Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material, and a special mold is used to mold a certain shape of paper product on a molding machine. Pulp molded products are a fast new packaging material in recent years and an excellent substitute for wood. Pulp molded products adopt the manufacturing process of raw material beating-ingredients-molding forming-drying-shaping. So what are the functional characteristics of pulp molding?
What are the functional characteristics of pulp molding:
1. The raw materials of molded pulp packaging products are waste paper and various fiber material paper mills. It has a wide range of sources and is easy to collect. It will not cause difficulties to the environment and recycling, and is conducive to the export of products. As foam plastics come from petroleum products, resource depletion and price problems will become more and more serious.
2. Containing and protecting packaging products is an important function of molded pulp products. Molded pulp products should be able to reliably contain the packaged products specified by the packaging, so that the packaged products will not be damaged during transportation, handling, and use, and It meets the requirements of strength, rigidity and stability by itself. The materials used in the molded pulp products are also safe for the packaged products, and there is no interaction between the two.
3. It is easy to use, that is, the structure of the pulp molded product 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.
4. Pulp molded products are modified to extend the corresponding time and absorb external energy through their special structure when loaded, so as to reduce the impact and vibration of the packaged objects. It is different from the cushioning mechanism of foam plastic packaging products, because foam products have a large number of compressible cells distributed inside 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 cannot be cushioned. 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.
5. Pulp molded packaging products have a wide range of applications. Now foam is used as a lining product. Basically, pulp molded products can be used instead. Pulp molded products can be stacked and stored in stacks. Compared with foamed plastics, it occupies 1/2-2/5 less storage space and has lower transportation and storage costs.
