What are the factors that determine the quality of paper tray forming

Do you know how the paper tray is produced and processed? Why can the paper tray be formed when it is produced? Below, the paper tray manufacturer will take everyone to take a look at the factors that determine the shape of the paper tray.

1. The density of the build-up layer depends on the type of fiber, the beating conditions and the molding conditions, which determine the air permeability and bulk of the paper support.

2. The degree of fiber entanglement determines the strength of the paper support product in the thickness direction and the horizontal direction.

3. The obvious difference in structure between the laminated surface part and the middle part and the difference between the filter surface (the side of the laminated mesh) and the non-filter surface is due to the fact that fine fibers and solid particles such as fillers and additives are on the filter surface. The retention rate is low, and after the original long fiber forms a filter layer on the filter surface, the retention rate gradually increases along the thickness direction.

Fourth, the directionality of the fiber arrangement determines the anisotropy of the paper support product.

Baihua Paper Products Pulp Molded Environmental Protection Packaging Paper Tray (Paper Tray for short) is made of waste paper and raw paper edges as raw materials. After being pulverized and blended into a certain concentration of slurry, it is formed by vacuum adsorption on a special mold, and then passed through Air-dried and dried to form lining body packaging products of different types and uses.
