Pulp molded products are a fast new packaging material in recent years and an excellent substitute for wood. Pulp molded products are solid containers used to contain and limit the packaging, serving the circulation, storage and transportation of commodities, that is, they are mainly used in the transportation and packaging of commodities. Pulp molding has the advantages of light weight, cushioning, flame-retardant, moisture-proof, anti-static and other advantages of environmentally friendly packaging materials. Pulp molding saves resources, protects the ecological environment, and conforms to the development trend of international packaging industry materials. That
What are the functional characteristics of pulp molding:
1. The raw materials of molded pulp packaging products are waste paper and various fiber materials from 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 are not 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. 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.
4. Pulp molded products are modified by their special structure when loaded to prolong the corresponding time and absorb external energy, thereby reducing the impact and vibration of the packaged material. It is different from the cushioning mechanism of foam plastic packaging products, because foam products have a good cushioning performance because of the large number of compressible cells distributed in the material, regardless of the shape of the product.
If the pulp plastic film material and foam plastic are used to make a large plane respectively, it is obvious that the former can be cushioned, while the latter cannot be cushioned. Therefore, for pulp and plastic film products, a good structural design is to complete the protection of the contents. The basic guarantee for improving the shock absorption capacity during transportation and handling.
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.
The above content is an introduction to the functional characteristics of pulp molding. With the continuous progress of pulp molding technology, products that use styrofoam, EVA, blister, and cardboard as lining packaging can basically use paper trays. Instead. Paper-plastic products have good anti-static properties, are completely degradable, and are easy to recycle. They are very popular in the market today because they are more in line with my country's energy-saving and emission-reduction policies.
