How to judge the product quality of PVC cling film？
First of all, we can smell the smelling of PVC plastic wrap when we open the box. Because qualified products are colorless and odorless, once the product has peculiar smell, it means that the quality is unqualified. Then, from the color point of view, the higher the transparency of the PVC plastic wrap, the better the quality, while the yellow plastic wrap, etc. are all waste recycling, and the quality is very poor.
Another way is to look at the elasticity of the film. Films that are prone to breakage are of poor quality when the film is pulled and tested. Film manufacturers remind us that the quality of a product is not determined by the thickness of the film, but by the toughness. The higher the toughness, the better the film quality
