A PE film is a type of plastic film made from polyethylene (PE) resin. Polyethylene is one of the most common types of plastic used in various applications due to its versatility, durability, and relatively low cost. PE films can be manufactured through processes like blown film extrusion or cast film extrusion, resulting in thin, flexible sheets of plastic. PE films find numerous uses across industries. They are commonly used as packaging materials for food products, pharmaceuticals, and consumer goods due to their excellent moisture resistance, flexibility, and ability to seal. Additionally, PE films are used in agriculture for greenhouse coverings, mulching, and crop protection. They are also employed in construction for vapor barriers and protective coverings.
