Why are the commonly used inner pallets of packaging boxes made of paper?

1. Dry pressed paper tray: This type of tray is used in the market as a product protection for packaging, such as trays for storing eggs. Its raw materials are waste newspapers and pulp, with a dark yellow color, which is not environmentally friendly, let alone hygienic. However, the mold price and unit price may be slightly lower. After the product is formed, it needs to be dried in the sun, so it is called dry pressing. The production of the product is affected by the weather and is most afraid of moisture.

2. Wet press paper tray: The material is sugarcane bagasse, which is environmentally friendly and can reach the food grade. It has a beautiful appearance and is generally aimed at some high-end or branded products, but the mold price and product unit price will be higher. After the product is formed, when it is still wet, it is directly hot pressed at high temperature, and the product comes out, so it is called wet pressing. The production of the product is not affected by the weather.

For environmental protection, the raw material of paper pallet packaging is waste pulp, which not only does not pollute the environment, but also helps to save resources and protect the environment. The paper tray has a wide range of applications. With the improvement of paper mold technology, the products using foam as the inner lining packaging can be exchanged with paper tray. The production cost of paper trays is relatively low, and the process of paper trays is simpler and faster than that of foam adhesive. The production time and cycle are shorter, and the cost and raw material cost are lower. It can avoid static electricity, is not afraid of erosion, and prevents vibration. These functions are superior to foam adhesive and are superior to other materials in many aspects.
