Pulp molding is a three-dimensional paper making technology. It takes waste paper as raw material and moulds a certain shape of paper products on the moulding machine. It has four advantages: raw materials for waste paper, including board paper, waste carton paper, waste white paper, etc., a wide range of sources; Its production process is completed by pulping, adsorption molding, drying and shaping, etc., which is harmless to the environment; Can be recycled and reused; Volume is smaller than foamed plastic, can overlap, convenient transportation. Pulp molding, in addition to dining boxes, tableware, more industrial buffer packaging, the development is very rapid.
Containment and protection of packaging products is the primary function of pulp molding products. The pulp moulded products shall be able to hold the packaged products as specified in the packaging reliably, so that the packaged products will not be damaged in the process of transportation, handling and use, and meet the requirements of strength, stiffness and stability. The materials used in pulp moulding products are also safe for the packaged products and do not interact with each other.

Easy to use that is, the structure of the pulp molding products should be agreeable. The structure and shape of the pulp molding products should not harm the human body and adapt to the operation and handling of the human body in the process of use.
Furthermore, pulp molding products are denaturated by their special structure during loading to prolong the corresponding time and absorb external energy, so as to reduce the impact and vibration of the packaged goods. It is different from the cushioning mechanism of the foam plastic packaging products, because of the foam products, with a large number of compressible materials due to the internal distribution of bubble hole, no matter why products shape, it has good buffer performance, if use the pulp plastic membrane materials and foam respectively made a big plane, the former is obviously to buffer, and the latter is not cushion, Therefore, for the paper pulp plastic film products, good structural design is the completion of the protection of the interior, in the transportation and handling process to improve the basic guarantee of shock absorption capacity. The designed structural performance will directly affect the strength, stiffness, stability and practicability of the package, that is, the structure of the pulp molding product directly affects the realization of its packaging function.
