What is the difference between POF shrink film and PVC shrink film?

Accepted Answer

POF shrink film, also known as polyolefin shrink film, offers superior clarity and flexibility. It offers superior puncture resistance and tear strength, providing excellent product protection. PVC shrink film is made from polyvinyl chloride. PVC shrink film contains chlorine elements. During production and recycling, it releases harmful chemicals. Therefore, PVC shrink film faces restrictions in many applications. POF recycling is more environmentally friendly. For enterprises pursuing sustainable development, POF shrink film is a more suitable choice.
