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.
