The composite bag cannot be scraped off. Composite bags are expensive, while ordinary plastic bags are cheap. Plastic composite bags are generally composed of BOPP and co-extruded films, BOPP and PET, and so on.There are many kinds of packaging materials and packaging bags on the market, and there are too many to list. Today, I will briefly introduce several common packaging materials, two-composite and three-composite, composite bags are usually photocopying, and those printed in the middle of the two films are generally tear-off composite bags. There will be two layers or one layer on the sexual side. This is a composite bag. The ordinary bag is printed on the surface of one layer, and the printing on it can be scraped off with a small input.
