The hollow board is a new environmentally friendly plastic sheet. The material is pp, hollow structure, waterproof, moisture proof, dustproof, and other properties. When producing hollow plates, it is preferred to set the thickness and material density of the hollow plates in the machine. The material density is also called gram weight, which is the weight of the hollow plate of 1 square meter. For example, 1 square meter, the thickness of the hollow plate with a thickness of 5mm is 850g, then the weight of this hollow plate is 850g.

The thickness of the hollow plate varies from 2mm to 12mm, and the conventional weight of the hollow plate with different thicknesses is as follows:
