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.
