EPE rolls are made from EPE EPE, but there are many poor-quality EPE rolls on the market, as well as a peculiar smell. So in addition to these, are there other ways to judge the quality of pearl cotton rolls? Bubble film manufacturers share the following small knowledge

1. "Touch" texture. As usual, pearl cotton rolls have a smooth surface, which is not good if there are particles.

2. "Pinch" softness. The texture of pearl cotton roll is very soft and can be shaped into any shape at will

3. "Smell" the smell. The important material of pearl cotton roll is EPE. Good pearl cotton roll has no odor, and the bad one has strange smell. It is likely that polyethylene is blended.

4, "burn" the smell of smoke. The material is mixed with plastic and other impurities, and the pearl cotton rolls will emit black smoke and have a pungent odor. And good materials will not only emit black smoke and odor after burning.

Bubble film manufacturers say that pearl cotton rolls, as an environmentally friendly material, have a wide range of uses.
