Paper tray manufacturers Paper trays are actually the packaging linings of various products that can be seen everywhere in life. The paper trays are made of pulp as raw material, and a mold with a stainless steel filter screen is used to dehydrate the pulp under pressure (negative pressure or positive pressure). , Various packaging linings produced by fiber forming. Paper tray production mainly includes pulp preparation, forming, hot pressing, molds and other processes. Since most of the pulp used in paper tray products uses waste paper as raw material, which responds to the environmental protection requirements and the green development direction of packaging specified by the country, what are the differences between dry pressed paper trays and wet pressed paper trays?
The difference between dry pressed paper tray and wet pressed paper tray:

The color is dark yellow, not environmentally friendly, let alone hygiene, but the mold price and unit price will be slightly lower . After the product is formed, it needs to be dried in the sun, so it is called dry pressing, and the production of the product is affected by the weather.
At present, the applications of dry pressed paper trays include: egg trays, inner trays for middle and low-end products, and rough large-scale product packaging.
2. Wet press paper tray: The material is bagasse, the product is environmentally friendly, and can reach the level of food use, and the appearance is beautiful. Generally, it is aimed at some products, but the mold price and product unit price will be higher. After the product is formed, when the product is still wet, it is directly hot-pressed at high temperature and the product comes out, so it is called wet pressing, and the production of the product is not affected by the weather.
