Translucent, a little waxy. Is it po, PE, OPP or some other material? Is it expensive to buy? The more detailed the expert answers, the better. Thank you
it seems that most of them are made of PP, but also PE and PVC. PP is brittle, hard in texture, slightly expensive in price, good in environmental protection performance, high in transparency, smooth and soft in texture and relatively low in price.
