How is POF Heat Shrink Film Manufactured?

Currently, the market offers a wide variety of heat shrink films, including PE, PVC, PP, POF, and other types. Environmentally friendly POF shrink film stands for biaxially stretched polyolefin shrink film. As an eco-friendly shrink film, it is widely used globally and shows a rapid growth trend. So, how is POF heat shrink film manufactured?

POF stands for multi-layer co-extruded polyolefin heat shrink film, consisting of a linear low-density polyethylene core layer (LLDPE) and copolymer polypropylene (PP) inner and outer layers. The manufacturing process involves melting and extruding the materials through three extruders, followed by shaping through a die head and processing using special techniques like bubble inflation to create the film.

POF heat shrink film is primarily used for packaging products with regular and irregular shapes. Its features include non-toxic and eco-friendly properties, high transparency, high shrinkage rate, excellent heat sealing properties, high glossiness, toughness, tear resistance, uniform heat shrink characteristics, and suitability for fully automatic high-speed packaging. Therefore, POF heat shrink film has become a substitute for traditional PVC heat shrink film.

POF heat shrink film products are produced using advanced biaxially stretched three-layer or five-layer co-extrusion technology, offering high transparency, high shrinkage rate, toughness, excellent heat sealing properties, anti-static properties, excellent cold resistance, and safe and reliable flexible shrink film characteristics.

In conclusion, POF heat shrink film has gained popularity in recent years as a new alternative product and is gradually becoming more prevalent in the market.
