Including egg box, egg holder, fruit holder, flowerpot, disposable medical bedpan, etc. It takes waste paper as raw material, adds some moisture-proof agent (aluminium sulfate) or waterproof agent, and then makes model products of various shapes according to different uses. It can be used as packing liner for eggs, fruits, precision devices, fragile glass, ceramics, crafts, etc. It has good cushioning and protection performance. The equipment of pulp moulding technology develops very fast. The basic process is pulp preparation, moulding, drying and shaping. The domestic equipment is mainly semi-automatic, while almost all the foreign equipment is fully automatic and high energy consumption pipeline.
IV. Functions of Pulp Molded Products
The function of pulp moulded products is to contain and protect the packaged products, which is convenient and practical.
Inclusion and protection of packaging products is the primary function of pulp moulding products. Pulp moulded products should be able to reliably accommodate the packaged products specified in the packaging, so that the packaged products will not be damaged during transportation, loading and unloading, 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 there is no interaction between them.
The structure of pulp moulded products should be pleasant for easy use. The structure and shape of pulp moulded products should not endanger the human body and adapt to the operation and handling of the human body in the use process.
Thirdly, pulp moulded products can prolong the corresponding time and absorb external energy by changing their special structure during loading, thus reducing the impact and vibration of the packaging. It is different from the cushioning mechanism of foam plastic packaging products, because the foam material products, because of the distribution of a large number of compressible bubbles inside the material, regardless of the shape of the products, it has good cushioning performance. If the pulp plastic film material and foam plastic are made into a large plane, the former can be buffered. The latter can not be buffered, so for pulp plastic film products, good structural design is the basic guarantee to complete the protection of the contents and improve the shock absorption capacity in the transportation and handling process. The designed structure and performance will directly affect the strength, stiffness, stability and practicability of the packaging, that is, the structure of the pulp moulded products will directly affect the realization of its packaging function.
