Compared with ordinary cardboard, the plastic hollow board has the advantages of moisture resistance, corrosion resistance, and lighter weight. It is currently widely used in many industries. Below, Corrugated Plastic Case Manufacturers introduces how to select high-quality hollow board:

1. Color: First observe from the color of the hollow board. The color of the high-quality plastic hollow board is bright and shiny, and the hollow board of the same color has uniform color and no color difference. Take the plastic hollow board to a place with good light. If you find that the color is dark or white-gray, then the raw material for the production of the plastic hollow board may be problematic.

 
2. Density: Generally, the higher the density, the better the quality of the board. Take two plastic hollow boards of the same size and place them in the left and right hands respectively, and tip them. The heavier hand feels better. The higher the density, the better the impact resistance. better.

 
3. Physical properties: Take a small piece of plastic hollow board and fold it in half by hand. The tough board is of better quality, can better deal with various situations during use, and has a better service life, but it is hard and brittle And the ones that are too soft are not very good.
