The Products Function of Molded Pulp Packaging

The molded pulp packaging is a new booming packaging material in recent years and it is a good substitute for wood. On the earthquake excellent performance, reasonable price, the whole cycle of degradation and pollution-free use of the advantages, it will entirely replace the EPS foam. The paper pulp compression molding product had the very long history, very early is a paper product member. It takes waste paper as raw material and added with moisture proof agent (aluminum sulfate) or waterproofing agent. According to different purposes, paper pulp packaging can be manufactured into various shapes and sizes to provide safe protection for the products due to its good buffer protection performance. Its basic process includes: materials preparation, molding, forming, drying and shaping.



It has four major advantages: wide source range; the raw materials include all kinds of waste paper or paper board; its production process is completely harmless to the environment and the products can be recycled; the volume is smaller than foamed plastics and it can be overlapped. This kind of products is mostly applied to industrial packaging.

Tolerance and protection is the first function of molded pulp packaging products. They should be reliable for packaging products, preventing the products from being damaged in the transportation, loading and unloading and use, and meet the requirements of the products' strength, stiffness and stability.

Easy to use makes the molded pulp products seem more human that their shape or structure should not harm the human body and they are convenient in operation, handling and carrying.

Molded pulp products extend the corresponding time and absorb energy through the character change of their own special structures when they are loading, thereby reduce the shock and vibration. It is different from cushioning mechanism of the foam plastic packaging products, due to the internal distribution of bubble hole, no matter what the product's shape is, it has good buffer performance. For instance, the paper pulp and foam materials are respectively used to make a big plane, the former is obviously good in buffer performance while and the latter is not. And plastic products cannot meet the requirement of large-scale package as the bad cushioning performance. So as for the pulp products, good structural design is the basic guarantee in its complete protection, improvement of the damping capacity in the process of transportation and handling.
