What is the difference between PVC shrink film and POF shrink film

Author: admin / 2022-03-09
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 also different, among which POF shrink film is a transparent glossy And the packaging film that is close to the appearance of the product has the characteristics of energy-saving and environmental protection, high shrinkage rate, transparent luster, and strong tear resistance, which subverts the limitations of traditional packaging films, and is well received by the market and consumers. favorite. Today, I will tell you 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 paints, the main component in the middle is polyethylene, and the lower layer is a back coating adhesive. It also has the unique properties of rainproof, fire resistance, antistatic and easy molding, and is widely used in the 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 copolymerized polypropylene (PP) as the inner and outer layers, and is plasticized and extruded through three extruders. It is processed by special processes such as die forming and film bubble inflation. POF is a packaging film with environmental protection, 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 product for traditional packaging. It, Widely used in audio and video products, tobacco, non-staple food, gifts, washing products, and so on.
