The scope of application of paper trays is becoming wider and wider. With the continuous advancement of pulp molding technology, products that use styrofoam, EVA, blister, and cardboard as lining packaging can basically be replaced by paper trays.
Paper trays can be divided into three categories: industrial paper trays, agricultural paper trays and food paper trays.
1. Industrial paper tray: Mainly used in lining packaging of home appliances, medical equipment, electrified materials, and lighting.
2. Agricultural paper support: mainly used for fruits, poultry eggs, agricultural nutrition bowls, etc.
3. Food paper tray: mainly used in food bowls, pots, supermarket food trays, etc.
Pulp molded products have developed rapidly and have good prospects because of their unique performance advantages:
1. The process technology is simple and practical, and there is basically no pollution in the production process, which meets the requirements of cleaner production. In addition, each process of its production line, except that the management of the automatic control system requires high quality of personnel, the rest are all skilled technologies, which can be mastered after short-term training, and the degree of localization of its equipment is very high, which is very conducive to the popularization of the project. Promotion, which is also a convenient condition for quickly taking advantage of the environmental protection advantages of pulp molded products.
2. Wide sources of raw materials and low cost. It is mainly made of waste paper or annual herb fiber pulp. The raw materials can be adapted to local conditions, and the raw materials can be obtained on the spot, which is inexhaustible and inexhaustible.
3. It has good shock resistance and cushioning properties, and uses the suspension method to generate adsorption, which can effectively protect the product from damage during transportation.
4. Light weight, low recycling cost, and can be used repeatedly.
5. Good protection, interchangeability and decoration performance.
6. From production and use to waste disposal, there is no pollution to the environment. The water consumption in the production process is small, no waste water is discharged, and environmental pollution is reduced.
7. Good air permeability, which has unique advantages for the packaging of fresh products.
8. Pulp molded products have good water absorption, hydrophobicity and heat insulation. Various additives can be added according to customer requirements during pulping to make the product resistant to acid, alkali, sunlight, water, oil, leakage, and deformation.
9. Modern production technology can realize high-speed, automated mass production.
10. Compared with traditional packaging materials, such as styrofoam (EPS), EPE foam, etc., it has a small volume and can be stacked and stored, saving stacking space and transportation costs.
11. According to the different requirements of users, the surface quality, color, graphics and other appearance elements of the product can be post-processed to meet the needs of product display.
