The design of pulp molded products is not only of structural equipment, but also is determined by raw materials, additives, fillers and production technology. Therefore, the design of pulp molded products is a comprehensive process of technology and structure. In addition to the strength and toughness of paper products, pulp molded products can also be made into various complex shapes according to the functional requirements. When used as industrial inner packaging, its shape is very complex and must meet the three standards of industrial inner packaging.
First, positioning requirements. The packaged products must be able to ensure that the packaged articles have a fixed position in the packaging box. The shape of the packaged products and the packaged articles shall be synchronous, the contact shall be appropriate and the size shall be accurate.
Second, buffer requirements. The whole product shall have certain toughness and flexibility, and the surface shall be soft. When contacting and rubbing with the packaged articles, the surface gloss of the packaged articles shall not be damaged, and the impact caused by collision and vibration during handling can be eliminated.
Third, bearing. The products are required to have certain strength and rigidity to support the packaged goods and bear external pressure. In order to meet the above functional requirements of products, in addition to selecting appropriate raw materials, additives and production processes, structural design is more important.
