Density of POF heat shrink film

POF heat shrink film is mainly used to package products of regular and irregular shapes. Because it has many advantages, it has been widely used. Do you know what the density of POF heat shrink film is? Let me give you a brief introduction today.

1. The shrink film has high puncture resistance, good shrinkage and certain shrinkage stress. It is mainly used in the sales and transportation process of various products to stabilize, cover and protect the products. The shrink packaging not only has a beautiful appearance, but also plays a role in moisture-proof, dust-proof, loose, anti-theft and collection.

2. The shrink film is divided into POF shrink film, PVC shrink film and PE shrink film. The density of POF is 0.925g/cm3; the density of PVC shrink film is 1.4/cm3; the density of PE shrink film is 0.993g/cm3. The shrinkage temperature of POF heat shrink film is: 130-150 degrees. The shrinkage temperature of PET shrink film is: about 200 degrees. The shrinkage temperature of PVC heat shrink film is: 80-100 degrees.

3. POF means heat shrink film. The full name of POF is multi-layer co-extruded polyolefin heat shrink film. It uses linear low-density polyethylene as the middle layer (LLDPE) and co-polypropylene (pp) as the inner and outer layers. It is plasticized and extruded by five extruders, and then processed by die head molding, film bubble blowing and other special processes.

In general, the density of POF heat shrink film is 0.925g/cm3. At present, POF heat shrink film is widely used in food, cosmetics, gifts, medicines, stationery, toys, audio-visual products, electronics, wood products, plastic hardware, daily necessities and other industries. The product is suitable for semi-automatic or fully automatic shrink packaging machines.
