Polyolefin Shrink Film is a plastic and a class of polymers, which are extracted from the polymerization of monomers. POF films are generally used as stretch films, shrink films and others. The most commonly used POF is polyethene. Polyolefin Shrink Film is a polymer produced from an olefin monomer. It is a polyolefin produced by polymerizing ethylene. POFs are used to make plastic bags, stretch films, shrink wraps, geomembranes, and other plastics.
