Disposable tableware widely exists in our lives, because of the advantages of low cost and convenience, even in the case of plastic, plastic ban "plastic" habit still exists. But now with the improvement of environmental awareness and the influence of low-carbon life, degradable meal boxes in the market gradually occupy a position, sugarcane pulp tableware is one of them. Sugarcane pulp belongs to a kind of pulp, the source is the sugar pressed bagasse, after pulp crushing, dredging, mixing, pulp, molding, cutting, disinfection, finished products and other steps made tableware. Sugarcane fiber is a medium long fiber, with moderate strength, moderate toughness advantages, is relatively suitable for making molding products as raw materials. The properties of bagasse fiber can be naturally twisted together to form a tight mesh structure, which can be made into a meal box for human use. The new green tableware, which has a good hardness, meets the needs of takeout packaging and home holding food, and is made of safe material, naturally degradable and can decompose into organic matter in the natural environment. These organic matter are usually carbon dioxide and water. Wouldn't our usual leftovers be composted with these boxes to save time sorting? In addition, bagasse can also be directly composted in daily life, processed with microbial maturation agent, and put directly into flower pots. Bagasse can make the soil loose and breathable, and improve the acidity and alkalinity of the soil. The production process of sugarcane pulp tableware is plant fiber molding, and one of its advantages is high plasticity, so now the tableware made of sugarcane pulp can basically meet the needs of family life and used in the gathering of relatives and friends. And in some high-end mobile phone support, gift box packaging, cosmetics packaging are used. Sugarcane pulp tableware in the production process is pollution-free, no waste water discharge, product safety testing and use quality is up to the standard, and one of the highlights of sugarcane pulp tableware, can be heated in the microwave oven (120°), can hold 100° hot water, can also be refrigerated in the refrigerator. With the continuous adjustment of environmental policies, products made of biodegradable materials have sprung up in the market, and eco-friendly cocoa degradable tableware will gradually replace plastic products in the future.

Pulp molding is a three-dimensional papermaking technology. It can use waste paper, wood pulp and various straw pulp as raw materials, and use a mold with a filter screen to form a certain shape of paper products on the special mold of the molding machine. Pulp molded products can be made into various shapes of model products according to different uses, most of which are auxiliary materials with protective functions for various products, generally including cushioning packaging materials, pulp molded agricultural products, pulp molded materials molded products, disposable tableware, etc. 1. Buffer packaging of industrial products: It is mainly used as the internal buffer packaging liner of industrial products, which can fix and protect the internal fragile products and precision instruments from collision during transportation. There are many kinds of buffer packaging, which is suitable for medium and small batch production. At the same time, it is necessary to design the geometric structure of buffer packaging according to the internal core products. 2. Buffer packaging of poultry, eggs and fresh fruits: It is mainly used for outer packaging of fresh foods such as poultry eggs and fresh fruits, and is suitable for various batch transportation. In the process of mass transportation, it is necessary to match the corrugated boxes placed in batches. It not only has the protection function, but also can isolate the internal items and prevent the friction and collision between the internal items; The strong permeability of pulp molding materials can absorb water to a certain extent, ensure the freshness of the goods, and better slow down the decay of fresh fruits loaded inside. Pulp molded agricultural products: It is mainly used for farm nursery products and flower protection. The seedling products made from it are also used to improve the quality of seedlings. Survival rate of agricultural products and preservation of agricultural and sideline products. Pulp molding material mold products: Generally, it is a special shape processed from pulp molding materials. It is generally a handicraft and can be used for household goods, household appliances, props, etc. Disposable environment-friendly tableware: Generally, white paper pulp is used as raw material, which is superior to traditional foamed plastic tableware in environmental protection. With the reduction of production costs and the rise of "paper instead of plastic", it is widely used.

At present, paper-plastic products made from reed, straw shell, sugarcane, wheat straw, bamboo, wood and other raw materials are more and more widely used, including protective packaging of industrial products such as electronic products, household appliances, instruments and meters, glass-ceramic paper products, small machinery, as well as retail packaging of high-quality paper-plastic products for consumer goods. What are the characteristics of pulp molded products? 1. The mold can produce products of various specifications and shapes, meet the packaging requirements of products of various shapes, and is easy to isolate and locate to prevent collision. 2. The paper is soft, the overall structure has appropriate strength and rigidity, and has good protection and cushioning performance. 3. Ideal inflation and moisture absorption are conducive to food preservation. As long as an appropriate amount of waterproof agent is added to the pulp, the paper molded products can obtain good water resistance. For example, the egg rack and fruit rack can be filled with water at no more than 35 ℃ within 24 hours, without water stains on the reverse side; This property is not required for industrial packaging, because waterproof should be used for storage, transportation and external packaging requirements. 4. As required, pulp molded products can be flame retardant, anti-static, waterproof, film-coated, printed, and can be used for retail packaging terminals. 5. In terms of protective packaging, pulp molded parts have more advantages than EPS, EPE and EPP buffers. A. The raw materials of pulp molded packaging products are waste paper and various fiber materials. Wide range of sources, easy to collect. It will not cause difficulties to the environment and recycling, and is conducive to the export of products. Foam plastic comes from petroleum products, and resource depletion and price problems will become more and more serious. B. Pulp molded packaging products have a wide range of applications. Now foam is basically used as lining products, and pulp molding products can be used instead. Pulp molded products can be stacked and stored in the stack. Compared with foamed plastics, it occupies less storage space and has lower transportation and storage costs. C. Paper products have good antistatic properties. The friction of foam plastic is easy to generate static electricity, so the use of paper packaging can better protect electronic products and household appliances. D. The water in the food packaged with plastic products is not easy to volatilize and lead to decay. The paper products have water permeability and air permeability, so as to achieve the antiseptic effect. E. At present, in terms of specific packaging costs, paper products are cheaper than foamed plastics. 6. Raw materials are widely used and can be used as waste, which has obvious social benefits and product recycling rate. Waste products and finished products in production can be used as raw materials for remanufacturing.

The function of pulp molding products is to contain and protect the packaged products, which is convenient and practical. Containing and protecting packaged products is the primary function of pulp molded products. Pulp molded products should be able to reliably contain the packaged products specified in the package, so that the packaged products will not be damaged during transportation, loading and unloading, and use, and they should meet the requirements for strength, rigidity and stability. The materials used in pulp molded products are also safe for the packaged products, and the two do not interact. Convenience of use, that is, the structure of pulp molded products should be pleasant. The structure and shape of pulp molded products should not damage the human body, and adapt to the operation and transfer of the human body during use. Furthermore, the pulp molded product prolongs the corresponding time and absorbs external energy through its own special structure denaturation when loaded, thereby reducing the impact and vibration of the packaged object. It is different from the cushioning mechanism of foamed plastic packaging products, because the products of foam materials, because there are a large number of compressible cells inside the material, no matter what shape the product is, it has good cushioning performance, if pulp plastic film material and The foam plastics are respectively made into a large plane, obviously the former can be cushioned, while the latter cannot be cushioned. Therefore, for pulp plastic film products, good structural design is the fundamental guarantee for protecting the contents and improving the shock absorption capacity during transportation and transfer. The designed structural performance will directly affect the strength, stiffness, stability and practicability of the package, that is, the structure of the pulp molded product directly affects the realization of its packaging function.

With the increasing awareness of global environmental protection, the paper pulp molding industry has made great strides in recent years and quickly become the new darling of all industries. Paper pulp molding products are made of abundant, recyclable and biodegradable plant fiber as raw material. There is no waste water and waste gas discharge in the production process. It is a veritable green packaging material and the most potential alternative to all kinds of plastic packaging materials. Compared with traditional packaging, pulp molding packaging has four advantages: Raw materials are natural and degradable; The production process is completed by pulping, adsorption molding, drying and qualitative process, which is harmless to the environment. Smaller than foamed plastic, overlapping, convenient transportation. Pulp molding, in addition to fast food boxes, kitchenware, a large number of industrial production cache packaging, the current development trend is very rapid. Pulp molding products can be made into a variety of shapes according to different uses, for all kinds of industrial products and food auxiliary protection. According to the application scenarios of pulp molding, it is classified into four main categories: (1) Catering packaging: paper pulp molding tableware, such as lunch box, convenient bowl, tray, paper cup, etc.; (2) Industrial packaging: electronic products and cosmetics liners, household appliances liners, nursing products liners, etc.; (3) Agricultural packaging: fruit trays, egg trays and other trays, seedlings and crops nutrition bowls, wine, medicine packaging, etc.; (4) Other packaging: , medical packaging,clothing packaging, gifts, toys, handicrafts bottom blank, furniture, display packaging, etc.

1. What are the ingredients used in disposable degradable lunch boxes and their respective proportions? The proportion of conventional lunch boxes is 70% - 90% sugarcane fiber+10% - 30% bamboo pulp fiber. Different tableware will also adjust the proportion of different fibers according to the shape, angle, hardness and stiffness of the product. Of course, wheat straw, wheat straw, reed and other plant fibers will also be added as needed. It is made of plant fiber without adding chemical materials such as PP and PET. 2. How can the disposable pulp lunch box achieve the effect of water and oil resistance? A certain amount of food grade additives will be added to the pulp molded lunch box. The general waterproof agent is 1.0% - 2.5%, and the oil repellent agent is 0.5% - 0.8%, so as to achieve the effect of water and oil resistance. The test is generally conducted with water at 100 ℃ and oil at 120 ℃ for 30 minutes; The oil temperature test time can be extended for special requirements. 3. Do degradable disposable tableware products contain fluoride? At present, most of the oil repellents in vegetable fiber tableware on the market contain fluoride, and the tableware that is waterproof but not oil repellent does not contain fluoride. If the degradable tableware is required to be fluorine free, waterproof and oil resistant, the current better alternative is film coating. PBAT is the most widely used composite material in the current pulp molded environment-friendly tableware. The products covered with film can better preserve the temperature, reduce the heat dissipation through the pores of the molded products, reduce the stickiness of rice, dumplings and other foods, and greatly reduce the use of waterproof agents and oil repellents. 4. How long can environment-friendly pulp tableware be completely degraded? In the absence of any industrial decomposer, it will take about 45-90 days for the paper pulp molded environment-friendly tableware to be completely decomposed in the natural state of the landfill site. No harmful ingredients will be produced, and no harm will be caused to land organisms, marine corals or marine organisms. After degradation, 82% of the ingredients are organic matter, which can be used as fertilizer for land use. The materials are natural and return to nature. 5. Can disposable pulp tableware be microwave heated and refrigerated? How much temperature can it reach? The degradable pulp lunch box can be heated by microwave and baked in an oven without harmful chemicals. The maximum temperature can reach 220 ℃. It can support refrigerator refrigeration, and the freezing temperature can reach minus 18 ℃. 6. What type of product quality inspection standard does the pulp molded lunch box meet? The biodegradable vegetable fiber lunch box complies with the national quality inspection standards of Pulp Moulded Tableware, the US Food and Drug Administration (FDA), the German New Food and Dietetic Act (LFGB), and other international standardized inspection standards. 7. Can the biodegradable lunch box be printed with logo? Logo can be printed. The printed products are mostly the circumference, bottom or top of the lunch box products. The cups, bowls and other products are mostly printed on the outside of the products. Curved surface printing is required. According to printing equipment, it can be divided into screen printing, pad printing and laser laser printing (inkjet printing). Printing products will increase product costs accordingly. 8. Have the raw materials used in white degradable lunch boxes been bleached? What bleach do you use? Unbleached plant fiber pulp is yellow and hard because it contains a small amount of lignin and colored impurities. Semi bleached pulp contains a large amount of pentosan, which is light yellow, commonly known as natural color. The fiber of bleached pulp is white, pure and soft, but the fiber strength is lower than that of unbleached pulp due to bleaching treatment. Hydrogen peroxide is generally used as bleaching agent, but chlorine is not allowed!

It seems more and more urgent to protect the environment. The amount of white pollution entering the sea in the increasingly abnormal weather is gradually increasing, and the carbon emission of the plastic industry has a tendency to exceed that of burning coal power. These signals have to make people think deeply. Is the earth now riddled with holes? In recent years, it is more and more difficult for plastic product packaging to enter the international market. Many European and American countries have already explicitly prohibited the use of foam plastic packaging and non degradable tableware. In China, such as Hangzhou, Hainan, Wuhan, Chengdu, Xiamen and the Ministry of Railways, clear laws have been issued to prohibit and restrict plastic products. Every field has to start a green packaging revolution - pulp molded packaging. Compared with traditional packaging, the advantages of pulp molded packaging for environmental protection are clear at a glance. 1. Pulp molding raw materials usually use natural plant fibers such as bagasse, which is much lower than the use of wood in traditional packaging boxes. Besides, sugarcane is renewable and has strong sustainability. 2. In terms of volume, pulp molded packaging boxes vary in size, but their weight and utilization rate of raw materials are less than those of traditional packaging boxes. The traditional packaging box can not be made without wood, but the raw material of pulp molded packaging comes from bagasse, causing little pressure on the environment. 3. Pulp molded packaging box is biodegradable and compostable. Due to the natural advantages of materials, under natural conditions, whether in the open air or in the landfill, the pulp molded packaging discarded within three months can be seriously or completely decomposed, and can be turned into fertilizer to achieve green sustainability, which greatly reduces the environmental pollution of packaging. 4. Strong design sense and high plasticity. Due to the integrated molding of pulp molded packaging during production, its production process is simple, production equipment investment is small, and energy consumption is low. And it can be changed into packaging for various industries, such as skin care products, Chanel, Runbaiyan's outer packaging, Tencent's moon cake gift box, and common disposable bagasse lunch boxes. The appearance of these packages just proves that today's environmentally friendly packaging and sustainable development are the right way. With the continuous improvement of people's living standards and the enhancement of environmental awareness, pulp molding will contribute more highlights to the cause of environmental protection.

In the era of culture promoting consumption and inspiration bursting at any time, coupled with the influence of We Media, the packaging of "paper instead of plastic" has shown new vitality in the packaging of light industrial products. Although pulp molding has developed rapidly in recent years because of its advantages of biodegradation, high plasticity and environmental protection and safety, it is still a relatively small industry and is slowly penetrating into our lives. For example, common egg trays, biodegradable lunch boxes available for takeout, and sustainable environmental packaging. This mooncake gift box is made of bagasse, which is biodegradable. The ice cream scoop board is made of bamboo, which has a good function of preventing ice cream from slipping. The ice cream box is made of natural sugarcane fiber molded packaging box (plant fiber molded), which is warm and easy to carry. The box can be used for storage. Pulp molded packaging will continue to shine in the packaging industry with environmental protection and fashion intelligence in the future. I hope to see more creative culture and paper packaging design.

Disposable tableware is ubiquitous in our lives. Because of the advantages of low cost and convenience, the habit of "plastic use" still exists even under the circumstances of plastic restriction and ban. But now, with the improvement of environmental awareness and the impact of low-carbon life, biodegradable lunch boxes have gradually occupied the market, including sugarcane pulp tableware. Sugarcane pulp belongs to a kind of pulp. It comes from the tableware made of sugar pressed bagasse through pulping, dredging, mixing, pulp supply, molding, trimming, disinfection, and finished products. Sugarcane fiber is a medium length fiber with moderate strength and toughness, which is relatively suitable for molding products at present. The characteristics of bagasse fiber can be naturally wound together to form a tight network structure, which can be made into a lunch box for people to use. This new type of green tableware has good hardness, which can meet the needs of takeout packaging and family food storage. It is also safe, biodegradable and can be decomposed into organic matter in the natural environment. These organic matters are usually carbon dioxide and water. If the leftovers we usually eat are composted with this kind of lunch box, wouldn't it save time for garbage sorting? In addition, bagasse can also be directly composted in daily life. It can be processed by adding microbial decomposition agent and directly put into flower pots to grow flowers. Bagasse can make the soil loose and breathable, and improve the soil's acidity and alkalinity. The production process of sugarcane pulp tableware is plant fiber molding, and one of its advantages is high plasticity. Therefore, tableware made of sugarcane pulp now basically meets the requirements of household life and tableware used in family gatherings. It is also used in some high-end mobile phone holders, gift boxes and cosmetics packaging. Sugarcane pulp tableware is pollution-free and free of waste water discharge in the production process. The safety detection and use quality of the product are up to the standard. One of the highlights of the sugarcane pulp tableware is that it can be heated in a microwave oven (120 °), can hold 100 ° hot water, and can also be stored in a refrigerator. With the continuous adjustment of environmental protection policies, degradable materials have sprung up in the market, and environment-friendly cocoa degradable tableware will gradually replace plastic products in the future.

Biodegradable packaging actually replaces traditional packaging with biodegradable packaging bags. At the beginning, it should be cheaper than the original plastic bags and paper bags, and the environmental protection indicators should be higher than the original plastic bags. Let this new material replace our traditional materials, create an environment-friendly earth, and let consumers enjoy the shopping experience better. Then let's learn about the applications of degradable materials in the food industry. Biodegradable raw materials are mainly used in packaging, synthetic fiber, agriculture and import. Among these packages, they are commonly used for packaging. Biodegradable raw materials are mainly used in packaging, synthetic fiber, agriculture and import. Among these packages, they are commonly used for packaging. The regulation of biodegradable raw materials has been greatly improved, including end products, packaging, agriculture and textiles. Biodegradable raw materials are also used in other fields. Especially in Europe, the diagnosis and treatment of nasal prosthesis and drug treatment system. Biodegradable materials are widely used in joint replacement, fixed steel plate, bone damage filler, human resource tendon, tendon, traditional Chinese medicine fixation, etc. in plastic surgery. Because of mastering many advantages of biodegradable raw materials, many scientific research institutions have begun to promote the application of this product. Degradable and environment-friendly packaging bags made of two different materials. One is made of renewable materials (such as bagasse, starch, etc.), which is called "environmentally friendly packaging bags for renewable materials". The other is the molecular formula interaction in the packaging bag made of degradable raw materials based on photothermal power generation. This kind of green packaging is also called "degradable plastic bag" The above contents are about the applications of degradable materials in the food industry. I hope they can help you after reading them.

Product features 1. Environmental protection: The molded pulp paper holder is made of sugarcane pulp or A4 pulp from the sugar factory and recycled paper products (carton leftovers). It does not need to cut down trees to destroy the ecology. The products can be naturally degraded into carbon dioxide and water after being buried in the soil, which will not cause adverse effects on the environment; 2.

Good protection: the fibrous tissue can form a very good buffer through the reinforcing rib; 5. Controllable cost: determine the production process of pulp molding according to the market positioning of the packaged products (dry press paper holder and wet press paper holder can be selected).

With the improvement of people's living standards, degradable disposable tableware has entered people's lives and gradually become one of the tableware most used in the market. The reason why disposable lunch boxes are so popular is that they bring us many benefits. Firstly, the biggest advantage of using degradable granular tableware is convenience. In the whole use process, you will find that the overall convenience is to take over and use it without cleaning or doing other work. For us, when we choose to use other tableware, this degree of convenience is almost impossible. Secondly, when using degradable disposable tableware, another advantage is that it is very clean and sanitary. Compared with traditional tableware, this product is only for one-time use and does not need to be used repeatedly, so it can truly ensure the overall cleanliness and hygiene, and there will be no first cleaning or disinfection work not in place. Thirdly, degradable disposable tableware is widely used, not only in restaurants, but also in hospitals, because hospitals are disposable. In addition, the current disposable tableware is also known as environment-friendly tableware because it is recyclable and can also be used as some industrial products after use. The above is a brief introduction to the benefits of degradable disposable tableware. Here we also remind users that disposable meal packs directly contact our health, so we should be careful to choose, and we must choose qualified disposable meal packs with regular manufacturers' production quality, in order to avoid affecting our health!

Advantages of disposable degradable tableware; It is harmless to human health. Because it is refined from corn starch and other environmental protection materials, it does not contain substances harmful to human health, and can be safely used for a long time. The zero pollution product is buried in the soil, and can be degraded to form carbon dioxide and water after 90 days at an appropriate temperature, which will not pollute the soil and air. Resource saving corn starch is a renewable resource, which is inexhaustible. Paper tableware and plastic tableware need a lot of wood and petrochemical products. Using corn starch as raw material can save a lot of petroleum and forest resources. High quality products have good tightness, water resistance, oil resistance, impermeability, and good high temperature and low temperature resistance. They are suitable for refrigeration, cold storage, fresh food, microwave heating, etc. Because polystyrene is non degradable and difficult to recover, it brings great inconvenience to the treatment. 1. Pulp molded tableware made of paper. It is mainly made of straw pulp, reed pulp and pulp through molding, trimming, drying and disinfection. 2. Disposable tableware made of corn starch. As the name implies, this kind of tableware is a disposable degradable tableware made of starch plants. Among them, paper tableware is the product with the largest production capacity and the largest number of production enterprises. As we all know, pulping and papermaking itself pollutes water resources, thus increasing the pressure on environmental governance! The disposable tableware made of corn starch is non-toxic, harmless and pollution-free, and can be degraded under natural conditions. The whole process from production to waste is pollution-free, which has been widely accepted by people. Its unique performance has become an incomparable substitute.

Today, let's make an inventory of disposable degradable lunch boxes on the market. 1. Pulp molded lunch box (vegetable fiber molded tableware) Pulp molded tableware products have certain advantages on the road of plastic prohibition. First of all, in terms of raw materials, the paper pulp molded disposable lunch box uses wheat straw, bagasse and other plant fibers as raw materials, without adding any PP materials. It is molded through the paper pulp molding wet pressing process. Food grade additives such as water and oil resistance are added to the paper pulp to achieve the effect of containing cold and hot food. Author: Watson degradable tableware. Vegetable fiber degradable lunch boxes are the most active type of lunch boxes on the market at present. Take Hainan Province, which is the first to ban plastic tableware, as an example. Hainan Province fully prohibits the use, circulation, sales and storage of plastic tableware. Pulp molded tableware is undoubtedly an ideal plastic substitute. Sugarcane pulp disposable lunch box is a fully degradable lunch box, which can be completely degraded into organic matter in 90 days under industrial composting or domestic composting conditions, returning to nature. 2. Corn starch lunch box The corn starch degradable lunch box is made of natural corn starch and plant fiber as the base material, supplemented by biological polyester, polyol and other materials. Corn starch degradable lunch box can be naturally degraded in soil and natural environment, and the degradation rate can reach 60% - 80% according to the composition of the lunch box. It can replace plastic products to a certain extent, reducing white pollution to the environment. It is an ideal substitute for the widely used but controversial "disinfection tableware" in the catering market. 3. PLA fully degradable lunch box PLA degradable lunch box usually refers to the product that combines PLA composite film and pulp molding product in the pulp molding process, namely PLA coated product. PLA composite membrane is a kind of completely degradable membrane produced and processed from polylactic acid, which can be compounded on pulp molding and paper products by heating. Polylactic acid (PLA) is a new type of biodegradable material, which is made from starch materials proposed by renewable plant resources (such as corn). The starch raw material is saccharified to obtain glucose, and then the glucose and a certain strain are fermented to produce high-purity lactic acid, and then the polylactic acid with a certain molecular weight is synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in the nature, and finally generate carbon dioxide and water, which do not pollute the environment. It is very beneficial to protect the environment and is recognized as an environmentally friendly material. In view of the advantages of PLA, the combination of the film covering process and the pulp molded products can not only save the use of waterproof and oil repellent agents, but also play a better role in sealing the pores of pulp molded products, so that the products that could not prevent alcohol can prevent alcohol leakage. At the same time, after the air hole is sealed, the tableware reduces the permeability of the product in the actual use process, with higher heat preservation performance and longer heat preservation time.

There are many kinds of disposable lunch boxes, including plastic type, cardboard type, starch type, pulp molding type, plant fiber type, etc. In recent years, environmental protection has been advocated. The original foam lunch boxes have been eliminated because they are not resistant to high temperature and the production process has caused environmental damage. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes, degradable lunch boxes, etc. Here is a brief introduction to the types of disposable lunch boxes. Being familiar with the materials, advantages and disadvantages of making them will help you to purchase them better. Cardboard lunch box Cardboard snack box is made of 300-350g bleached kraft wood pulp paperboard through die cutting and bonding, die cutting and pressing, shaping and other processes similar to sheet metal processing. In order to prevent oil or water seepage, it is necessary to coat its surface or apply chemical additives. It is non-toxic and has no side effects on human body during production and use. However, the quality of paperboard is required to be high, and the cost is also increased. Degradable plastic lunch box The raw material for making this kind of lunch box is degradable plastic. The so-called degradable plastic is that a certain amount of additives, such as photosensitizer, starch and other raw materials, are added in the production process of plastic. In this way, the degradable plastic products can be decomposed into fragments from the complete shape after being used and discarded in nature for three months, thus improving the environment visually at least. However, the disadvantage of this technology is that these fragments cannot be degraded any more, just change from large pieces to small pieces, and plastics are not fundamentally competent for the task of eliminating white pollution. Plastic lunch box The disposable lunch boxes made of plastic mainly include PP polypropylene and PS polystyrene, which are non-toxic, tasteless and odorless, and PP is relatively soft. Generally, PP is used at a temperature of - 6 ° C to+120 ° C, so it is particularly suitable for holding hot food, which can be heated in a microwave oven or even cooked in a steam cabinet. The use temperature of modified PP can be controlled at - 18 ° C to+110 ° C. In addition to being used at a temperature of 100 ° C, It can also be put into the refrigerator for refrigeration. In addition, plastic lunch boxes can also be recycled and more environmentally friendly. PS is hard and transparent, but it is easy to tear. PS starts to become soft when the temperature reaches 75 ℃, so it is not suitable for hot food.

Plant fiber pulp molding process is also widely used in the field of industrial packaging. Generally, it can be divided into high-quality industrial packaging and ordinary industrial packaging, both of which are different in terms of technology and raw material use. 1. High quality industrial packaging It is mainly made of sugarcane, bamboo and wheat as raw materials, and is a packaging container with shock proof, anti-static and compression resistant lining or outer box of high-end electronic products. The industrial packaging liner or container made of this material is fully biodegradable, which can be completely degraded into small biomolecules in 45-90 days under the conditions of industrial composting or domestic composting, returning to nature. It reduces the pollution of plastic products to the environment and is an excellent substitute for plastic products. In the production of high-quality industrial packaging, the mesh size is required to be high, generally more than 60 mesh. The product is more delicate and smooth than the tableware, and this type of packaging requires high precision. In the design process, it must be completely consistent with the angle and slope of the packaged product, and the positioning must be accurate. Therefore, this kind of packaging often has a 0 degree angle design, which is mostly used for the production of automatic machines or robots that do not rotate the net. At present, high-end products such as Dell tablet computers, Xiaomi mobile phones, HTC mobile phones, Gillette razors, etc. are all using high-grade industrial packaging such as pulp molding. Because of the restrictions of various countries on non degradable packaging containers, the demand for such packaging will explode. 2. General industrial packaging container It is mainly the pulp raw materials based on various cartons, newspapers, A4 papers, etc. These raw materials are cheap, reusable, and the production process is mostly dry pressing. This kind of packaging is mainly applicable to the shockproof protection of low-end electronic products or precision equipment. At the same time, the inner lining packaging of some alcohol and beverage products is also classified as industrial packaging.

I don't know whether the friends in front of the screen have seen a kind of tableware made of paper pulp. This kind of paper pulp tableware was actually born to replace the plastic tableware that we used to use before. Compared with plastic tableware, this kind of paper tableware has numerous advantages. In fact, it is not just paper tableware. There are many paper packaging like this, such as paper trays, some paper wine trays and bottle trays that we often see in our lives, paper shoe trays that we see when buying shoes, even egg trays that we hold eggs, and some industrial packaging are also made of paper pulp. This series of paper products can be called paper packaging, and it has another name "pulp molding"! Pulp molding has many advantages: low cost of raw materials, energy conservation and environmental protection in the processing process, and the finished product is not only beautiful but also green and environmentally friendly and can be naturally degraded. Among them, the degradable advantages of pulp molding should be emphasized. Compared with the difficulty of plastic products to degrade, pulp molded products can perfectly solve this problem. The latter can be completely degraded naturally, and it only takes about ten days. After decomposition, it will not cause any damage to the local soil.
