The function of the pulp molded product is to contain and protect the packaged product, which is convenient and practical.

Containing and protecting packaging products is the primary function of molded pulp products. Pulp molded products should be able to reliably contain the packaged products specified by the packaging, so that the packaged products are not damaged during transportation, handling, and use, and they should meet the requirements of strength, rigidity and stability. The materials used in the molded pulp products are also safe for the packaged products, and there is no interaction between the two.

The structure of the pulp molded product that is convenient to use should be pleasant. The structure and shape of pulp molded products should not harm the human body, and adapt to the operation and handling of the human body during use.

Furthermore, the pulp molded product is through its own special structure that deforms when loaded to prolong the corresponding time and absorb external energy, thereby reducing the impact and vibration of the packaged object. It is different from the cushioning mechanism of foamed plastic packaging products, because foamed products have a large number of compressible cells distributed in the material, regardless of the shape of the product, it has better cushioning performance, if paper pulp plastic film materials and Foam plastics are made into a large plane. Obviously the former can be cushioned, while the latter is not. Therefore, for pulp plastic film products, a good structural design is to complete the protection of the contents and improve it during transportation and handling. The basic guarantee of shock absorption capacity. The designed structural performance will directly affect the strength, rigidity, stability and practicability of the package, that is, the structure of the pulp molded product directly affects the realization of its packaging function.
