PE (Polyethylene) protective film is a common protective material used to shield various surfaces during manufacturing, transportation, storage, and installation. It prevents damage, dirt, and other contaminants from affecting the surface. The film is made from polyethylene, offering good flexibility and toughness. It can be transparent, semi-transparent, or opaque depending on specific requirements. PE protective film is easy to apply and remove, leaving no residue, making it ideal for protecting surfaces like glass, metal, plastic, and painted materials.
