There are many types of packaging films on the market, including pof shrink film, PVC shrink film, heat shrink film, pe heat shrink film, etc., according to their respective materials, their functions are not the same. The packaging film with luster and close to the appearance of the product, its energy saving, high shrinkage rate, transparent gloss, strong tear resistance, etc. have subverted the limitations of the traditional packaging film, and have been well received by the market and received by consumers. favorite. Today I will talk about the difference between pof shrink film and PVC shrink film:
PVC heat shrinkable film is a synthetic material with heat resistance, toughness, ductility, etc. The upper layer of this surface film is a lacquer, the main component in the middle is polyethylene, and the lower layer is the back coating adhesive. It also has the unique properties of rainproof, fireproof, antistatic, and easy to form, and is widely used in building materials industry and packaging industry.
POF heat-shrinkable film is a new type of heat-shrinkable film material, which uses linear low-density polyethylene as the middle layer (LLDPE) and co-polypropylene (PP) as the inner and outer layers, plasticized and extruded through three extruders. Then it is processed by special techniques such as die head forming and bubble inflation. POF is a packaging film with high transparency, high shrinkage, good heat-sealing performance, high gloss, toughness, tear resistance, and uniform heat shrinkage. It is suitable for automatic high-speed packaging and is a replacement for traditional packaging. It is widely used Used in audio-visual products, tobacco, non-staple food, gifts, washing products, and so on.
