What is the difference between PVC and POF heat shrinkable film? Which one is better?

    When the shrinking machine market is locked up, heat shrinkable film has started a new controversy. How to choose so many kinds of heat shrinkable film in the market? PVC, PE, PET and POF are our common heat shrinkable film. What is the difference between PVC and POF, and which one is better?

PVC

    The material is PVC, which is one of the largest plastic products in the world. It is cheap and widely used. The PVC resin is white or light yellow powder, which cannot be used alone and must be modified. PVC is white powder with amorphous structure, with low branching degree and poor stability to light and heat. Different additives can be added according to different uses, and PVC plastics can show different physical and mechanical properties. A variety of hard, soft and transparent products can be made by adding appropriate amount of plasticizer into PVC resin.

POF

Environment-friendly POF shrink film is the abbreviation of biaxial oriented polyolefin shrink film. It is a new type of environment-friendly shrink film which is widely used and developing rapidly in the world. This product adopts the advanced special technology of biaxial stretching and three-layer melting co-extrusion. Produce a safe and reliable soft shrink film with high transparency, high shrinkage, high toughness, high heat sealing performance, excellent antistatic and cold resistance.

    After reading the above introduction, it should be clear to everyone that POF has a great advantage, and we in Foshan Wellpomp always recommend customers to use the environmentally friendly POF heat shrinkable film.
