Classification of heat shrinkable film PE heat shrinkable film PE polyethylene, which is a transparent thermoplastic. There are three types of PE commonly used, namely: LDPE HDPE LLDPE The monomers of the three kinds of polyethylene are the same, but the process conditions used are different when synthesizing these polyethylenes, so three different polyethylenes are produced. Varieties, the properties of the three materials are quite different. PE film is a material with very good toughness, and it is not easy to pulverize with ordinary plastic grinders. Because the PE film is soft and tough, it is not easy to be shredded, not to mention the high temperature of the tool at high speed, which will cause the LDPE to melt and adhere to the blade. PE pelletizing can be directly put into the feeding port of the extruder into strips, and the PE film is dragged into the barrel by the shearing force of the screw to heat, melt, and extrude to pelletize. PE recycled first-grade materials can still be blown film, used for non-food and pharmaceutical packaging, and also widely used in the production of Oxford leather and tarpaulin, with a bright future. PE heat shrinkable film is widely used in the whole assembly packaging of wines, cans, mineral waters, various beverages, cloths and other products. The product has good flexibility, impact resistance, tear resistance, and is not easy to break and fear. Moisture and high shrinkage rate. PVC shrink film PVC heat shrink film PVC polyvinyl chloride, with additional ingredients to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. Due to the unique properties of PVC (rain-proof, fire-resistant, anti-static, easy to form) and low-input and high-output characteristics of PVC, it is widely used in the building materials industry and packaging industry. Therefore, PVC film has high transparency, good gloss and shrinkage. Features such as high rate. OPS heat shrinkable film OPS (oriented polystyrene) heat shrinkable film is a new type of skin packaging material that meets environmental requirements. OPS heat shrinkable film has high strength, high rigidity, stable shape, and good gloss and transparency. Convenient processing, easy coloring, good printing performance, and extremely high printing resolution. For trademarks that are constantly pursuing fine printing, it is completely an improvement in materials. Because of the high shrinkage and strength of OPS film, it can fit closely with various containers of different shapes, so it can not only print exquisite patterns, but also meet the use of various novel packaging containers with different shapes. A non-toxic, odorless, grease-resistant film that meets food hygiene standards allows designers to use eye-catching colors to achieve a 360° label design, giving full play to creativity and imagination, so that beverages and other products can be on the label The patterns in use are more vivid, highlight the image on the shelf, and produce an unexpected container effect. PET heat shrinkable film PET heat shrinkable film is a new type of heat shrinkable packaging material. Because it is easy to recycle, non-toxic, odorless, good mechanical properties, especially in line with environmental protection, polyester (PET) has become an ideal substitute for polyvinyl chloride (PVC) heat shrinkable film in developed countries.
