First, let’s understand the production process of wet-pressed paper trays. The manufacturing process of wet-pressed paper trays is mainly divided into three steps: raw material processing, wet-press molding, and drying.

The main raw materials for wet-pressed paper trays are waste paper and water. These raw materials need to be processed to give them high plasticity and adhesiveness. First, the waste paper is shredded into small pieces, then soaked in a large amount of water. At a certain temperature, the waste paper fibers disperse in the water and form a pulp.

After raw material processing, the pulp is transported to the molding machine. On the molding machine, the pulp is compressed into trays of the required size and shape. During the molding process, pressure is applied to the surface of the tray to make the fibers bond more tightly. At the same time, by using templates or special cutting tools, the tray can be cut into the required size and shape.

After the wet-pressed paper trays are produced, they need to be dried. During the drying process, the wet-pressed paper trays are sent to a drying chamber and dried using high temperature and strong air flow. This treatment makes the paper trays harder and more durable, while preventing deformation and deterioration.

The structure of wet-pressed paper trays is relatively simple. They are composed of multiple layers of paperboard, and each layer is compressed together to form a solid structure. This structure can bear weight and protect goods from damage.

Finally, let’s look at the advantages of wet-pressed paper trays. First, they are an environmentally friendly material. Since wet-pressed paper trays are mainly made of waste paper, they do not cause harm to the environment. Second, they are more economical than other packaging materials. The production cost of wet-pressed paper trays is low, and they can be reused, thereby reducing packaging costs. In addition, wet-pressed paper trays have good protective performance. They can effectively protect goods from damage and reduce the loss rate during transportation.

In conclusion, wet-pressed paper trays are a common type of packaging material. With their simple yet effective production process and environmental advantages, they have become an important part of the packaging industry.
