In our daily life, packaging materials can be seen everywhere, in which heat shrinkable films are widely used in all walks of life. The following small series will introduce the classification of heat shrinkable films.
1) PE heat shrinkable film is widely used in the whole package of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance, tear resistance, not easy to damage, not afraid of moisture and high shrinkage rate;
2) PVC film has the characteristics of high transparency, good gloss and high shrinkage;
3) POF has the characteristics of high surface gloss, good toughness, high tear strength, uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film. POF means heat shrinkable film. POF is fully known as multi-layer coextrusion polyolefin heat shrinkable film. It is made by plasticizing and extruding linear low-density polyethylene as the intermediate layer (LLDPE) and co polypropylene (PP) as the inner and outer layers through three extruders, and then processed by special processes such as die forming and film bubble inflation.
5) Characteristics of pet heat shrinkable polyester film: it is stable at room temperature, shrinks when heated (above glass transition temperature), and more than 70% heat shrinks in one direction. The advantages of heat shrinkable polyester film packaging are: ① close to the body and transparent, reflecting the commodity image. ② Tight packing, good dispersion resistance. ③ Rainproof, moisture-proof and mildew proof. ④ No recoverability, with certain anti-counterfeiting function. Heat shrinkable polyester film is often used in convenience food, beverage market, electronic and electrical appliances, metal products, especially shrinkable labels. Because with the rapid development of PET beverage bottles, beverage bottles such as coke, Sprite and various fruit juices need pet heat shrinkable film as heat sealing labels. They belong to polyester, are environment-friendly materials and are easy to recycle.
The above is the classification of heat shrinkable film, the packaging material collected by Hangzhou Chaohong plastic packaging Co., Ltd. our company specializes in the production and processing of PVC heat shrinkable film, PE heat shrinkable film, POF heat shrinkable film, pet heat shrinkable film, PE winding film and other products, such as PVC heat shrinkable film, PE heat shrinkable film, POF heat shrinkable film, pet heat shrinkable film, PE winding film and other products, Welcome to negotiate.
