When the paper tray product is loaded, through its special structure, it can extend the corresponding time and absorb external energy, thereby reducing the impact and vibration of the packaging. Pulp molding is different from the cushioning mechanism of foam packaging products, because regardless of the shape of the product, the material There are a large number of compressible foams distributed in them, and the foam products have good cushioning properties. If the paper pulp plastic film material and foam plastic are made into a large plane respectively, it is obvious that the former can cushion, but the latter cannot.
Paper trays, environmentally friendly paper tray products include egg trays, fruit trays, mobile phone paper trays, toy paper trays, disposable medical bedpans, etc. Pulp molding uses waste paper as raw materials, and adds moisture-proofing agent (aluminum sulfate) or waterproofing agent to the parts, depending on the difference Use to make model products of various shapes, with good cushioning and protection performance. The function of the paper tray product is to contain and protect the packaged product, which is convenient and practical.
Containing and protecting packaging products is the main function of paper products (3) The hardness and packaging strength of the product during transportation should not meet the specified requirements, and the product should not be reliably damaged during loading and unloading. The materials used in paper-supported products are also safe for packaging products, and there is no interaction between the two.
Therefore, for paper support products, a good structural design is the basic guarantee for protecting the contents and improving the damping capacity during transportation and handling. The structural performance of the design will directly affect the strength, rigidity, stability and practicability of the packaging, that is, the structure of the pulp molded paper support product will directly affect the realization of its packaging function.
