Density and introduction of shrink film

Common shrink films are PVC heat shrink film, POF heat shrink film and PE shrink film.

The density of PVC heat shrinkable film is: 1.4g/cm3

The density of POF shrinkable film is: 0.925g/cm3

The density of PE shrink film is: 0.993g/cm3

PVC heat shrink film is made of ethylene PVC resin mixed with more than a dozen auxiliary materials after secondary blowing, which is characterized by good transparency, easy shrinkage, high strength, shrinkage rate can be freely adjusted according to user needs, and strong operability! It can be made into tubular film, L-shaped folded film according to requirements, and can be processed into cylinder bags, flat bags, etc. It has a wide range of applications, mainly used for aluminum profiles, aluminum alloy doors and windows, stainless steel, silencing guide rails, wood line food and beverage packaging.

PVC heat shrink film is called multi-layer co-extruded polyolefin heat shrinkable film, which is made of linear density polyethylene as the middle layer and copolypropylene as the inner and outer layers, plasticized and extruded by three extruders, and then processed by special processes such as die molding and film bubble blowing. Due to its environmental protection, high transparency, high gloss, toughness, tear resistance, good heat sealing performance and suitable for manual, semi-automatic, fully automatic high-speed packaging and other characteristics, it is widely used in automotive supplies, stationery, daily necessities, food, cosmetics, medical supplies and other types of packaging.

PVC heat shrink film is mainly made of several different types of polyolefin resin mixed and extruded, with puncture resistance, super strength and high performance, and the goods stacked on the pallet are wound and packaged, making the packaging more stable and tidy.
