1. It can form products with various specifications and complex shapes through molds, so that you can get used to the packaging requirements of products with various shapes, which is convenient for blocking positioning and avoiding bumps.
2. The paper is light and soft, and the overall structure has suitable strength and rigidity, which makes it excellent in maintenance and cushioning.
3. It has ideal ventilation and moisture absorption, which is conducive to the preservation of food. As long as the appropriate amount of waterproofing agent is added to the slurry, the paper molded product can obtain excellent water resistance; for example, egg trays and fruit trays can be incompatible with water marks within 24 hours after being filled with water not higher than 35°C; but The inner packaging of general industrial products does not need to have this function, because waterproofing should be a requirement for storage, transportation, and outer packaging.
4. According to needs, pulp molded products can be flame-retardant, anti-static, waterproof, laminating, printing, and applied to terminal retail packaging.
5. In terms of protective packaging, pulp molded parts have many advantages over EPS, EPE, and EPP cushioning parts: the raw materials of molded pulp packaging products are waste paper and various fiber materials. The sources are wide and easy to collect. The environment and recovery constitute an obstacle, which is conducive to the export of products. However, foamed plastics are derived from petroleum products, and the problem of resource depletion and price will become more and more serious.
Pulp molded packaging products have a wide range of applications. The products currently using foam as lining can basically be replaced by pulp molded products. Pulp molded products can be stacked and stored, and the storage space occupied by foamed plastics is 1/2~2/5 smaller, and the freight and storage costs are smaller.
Paper products have good anti-static properties, and the friction of foamed plastics can easily generate static electricity, which plays a good role in maintaining electronic products and home appliances.
When plastic products are packaged, the water content of the food is not easy to volatilize, and it is easy to mold and decay, while paper products have the function of water vapor permeability, and then achieve the anti-corrosion effect.
Now, paper molded products are cheaper than foam plastics in terms of specific packaging costs.
6. The materials are extensive and can be used as wastes, and the social benefits are significant. The products can be recovered and reused at a high rate. Regardless of the waste products in production or the used products, they can be made from scratch.
All the external elements that the package comes into contact with in the circulation link are the circulation environmental elements. The circulation environment factor is the primary external factor that causes damage to the package.
The environmental factors that affect the planning of the pulp molded cushion liner mainly include the following three categories:
1. Physical and mechanical elements mainly refer to external elements such as shock and vibration in the transportation link, and stacking in the storage link. Before planning the pulp molding cushioning liner, it is necessary to fully understand the loading and unloading equipment, loading and unloading height, transportation methods and means in the transportation link, and the number of stacking layers in the storage link. Oscillation will cause the fiber to fall off the surface of the molded pulp cushion and scratch the surface of the packaged product, and make relative adjustments to different product characteristics.
2. Biochemical elements mainly include the effects of natural conditions such as temperature, humidity, rain, radiation, harmful gases, and microorganisms. Among them, the humidity in the transportation and storage links has a relatively large impact on the pulp molded cushion liner, which can cause the risk of the cushion liner to be damp and fail.
3. Human factors, mainly refer to barbaric loading and unloading, etc. The drop impact caused by the loading and unloading process will damage the package more severely and is the primary consideration. Clear the nature of the packaged product
The packaged product is the research object of the pulp molding product planning. Before the structural planning, the primary properties related to the planning must be clarified, including the shape, quality, size, fragility, fragile value, vulnerable parts, accessories, and other aspects of the packaged product. Size and so on. In addition, it is necessary to understand the customer's planning requirements.
