1. According to needs, pulp molded products can be flame-retardant, anti-static, waterproof, laminating, printing, and applied to terminal retail packaging.
2, the paper is light and soft, and the overall structure has suitable strength and rigidity, which makes it have good protection and cushioning properties.
3. Various specifications and complex shapes can be produced through molds, so that it can adapt to the packaging needs of various shapes of products, facilitate isolation and positioning, and prevent collisions.
4. It has ideal ventilation and moisture absorption, which is conducive to the preservation of food. As long as an appropriate amount of waterproofing agent is added to the slurry, the paper molded product can achieve good water resistance; for example, egg trays and fruit trays can be filled with water not higher than 35 ℃ within 24 hours without water marks on the reverse side; but generally The inner packaging of industrial products does not need to have this performance, because waterproofing should be a requirement for storage, transportation, and outer packaging.
5. In terms of protective packaging, pulp molded parts have many advantages over EPS, EPE, EPP cushioning parts: the raw materials of molded pulp packaging products are waste paper and various fiber materials, and the source is easy to collect, and it is not harmful to the environment. And recycling create obstacles, which is conducive to product export. However, foamed plastics are derived from petroleum products, and resource depletion and price problems will become more and more serious.
6. The raw materials can be used as wastes, and the social benefits are obvious. The recycling rate of products is high. No matter the waste products in production or the finished products after use, they can be used as raw materials for re-production.
All external factors that the package comes into contact with in the circulation link are the circulation environmental factors. Circulation environmental factors are the main external factors that cause damage to the packaging.
