Types and characteristics of heat shrinkable film

Types and characteristics of heat shrinkable film Heat shrinkable film is used for the sales and transportation of various products, and its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and a certain shrinkage stress. During the shrinking process, the film cannot produce holes. Since shrink film is often used outdoors, it is necessary to add UV anti-ultraviolet agent. Types of heat shrinkable film 1. PE shrinkable film PE polyethylene, which is a transparent thermoplastic. 2. POF shrink film POF has the characteristics of high surface gloss, good toughness, high tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film. 3. OPS shrink film OPS shrink film is a new type of skin packaging material that meets environmental requirements. OPS heat shrink film has high strength, high rigidity, stable shape, and good gloss and transparency. 4. PET shrink film PET heat shrink film is a new type of heat shrink packaging material. Because it is easy to recycle, non-toxic, odorless, good mechanical properties, especially in line with environmental protection, etc., in developed countries, polyester (PET) has become an ideal substitute for polyvinyl chloride (PVC) heat shrinkable film. The heat shrinkable film features high flexibility, not easy to break, strong blast resistance, strong impact resistance, strong tear resistance, strong tensile force, and can replace box packaging. The shrinkage rate is large, and the items can be tightly wrapped after heat shrinking. If the PE straight-through bag (opening at both ends of the bag) is heat-shrinked, the two ends of the opening can lift the items, which can bear a weight of 15KG, which is convenient for handling. It has good transparency and 80% light transmittance. It can display products and promote products invisibly. At the same time, it also reduces distribution errors in the logistics link. Moisture-proof, waterproof and dust-proof, it can not only achieve the packaging effect, but also beautiful and protect the product. Non-toxic, tasteless, and pollution-free are environmentally friendly packaging materials. PE heat shrinkable film application scope: medicine, beverage, mineral water, beer, laminate flooring, palletizing, building materials, metal products, dairy products, glass bottles, industrial paper and other large-scale packaging equipment, articles, etc. Previous: Characteristics of pet heat shrinkable film Next: Characteristics of shrinkable film
