Nowadays, there is an increasing demand for plastic corrugated sheet in the market, and people who often use it will find that its quality on the market is uneven, which is very troublesome. Then here we share some methods to distinguish the quality of plastic corrugated sheet:

The first way is to pinch, because the hardness of the poor hollow board is the worst, the edge part of the hollow board will be dented by hand. If it is found that the hollow board is dented gently, and even the original shape cannot be restored after the dent, Or it can be torn by gently tearing it with your hands. This kind of hollow board must be a low-quality hollow board.

The second way is to see whether the surface of the hollow board has a certain gloss and the color of its cross-section. The high-quality hollow board is made of new raw materials, with good color gloss, no pitting, slight spots, moths, and decay. And other problems exist.
