Plastic film refers to the use of resins such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, etc. as the main raw materials, mixed uniformly with other additives in a certain proportion, then molded into plastic products with a certain thickness (thickness of 0.01-0.25 millimeters), infinite width, smooth soft surface on plastic molding machinery.

1. The use of plastic film

The application of plastic film can be seen everywhere in agricultural production, as a mulching film packaging for various agricultural products; As packaging for various industrial products in industrial production; In people's daily lives, composite films are used as packaging rainproof tools for clothing food, as well as toy decorations, for special functions on various material surfaces.

2. Types of plastic films

BOPP plastic film only has the advantages of low density, good corrosion resistance, heat resistance of PP resin, but also has good optical properties, high mechanical strength, abundant raw materials. PVA high barrier composite film is based on polyethylene plastic, which has good barrier properties meets environmental requirements. It has a broad market space in the food industry. LDPE polyethylene products have 8 major categories, including low density, softness, low temperature resistance, good impact resistance, good electrical insulation performance, polyester film (PET), nylon polyamide (PA), cast polypropylene film (CPP), aluminum plated plastic film, etc.
