PE PE polyethylene shrink film, it is transparent thermoplastics. PE commonly used three categories, namely: LDPE HDPE LLDPE Polyethylene three kinds of monomers are the same, but, in the synthesis of these polyethylene, used in the process conditions are not the same, so it generates three different polyethylene Variety opp shrink film, performance of the three materials are quite different. PE film is a very tough material, not easy to use ordinary plastic grinder crushed. Because PE film soft and tough, not easy to shred, not to mention the high speed cutting tools, high temperature, make LDPE melt adheres to the blade. PE granulation, can be placed directly into the extruder feed inlet section, the shear force by the screw barrel heating PE film dragged melt extrusion granulation. PE recycled material level, still be blown film for non-food and pharmaceutical packaging, but also widely used in the production of waterproof leather and waterproof, the future is bright. Features PET polyester film of heat-shrinkable type: it is stable at room temperature, heating (above the glass transition temperature) shrink heat shrinkable film printing, and is more than 70% of thermal shrinkage occurs in one direction. Shrinkable polyester film packaging advantages are: ① fitted transparent, reflecting the product image. ② tight packaging, anti-casual good. ③ rain, moisture, mildew. ④ no resilience, there is a certain security features. Shrinkable polyester film used in convenience food, beverage market, electronics, metal products, especially shrink label is its most important applications. With the rapid development of shrink film because PET beverage bottles, such as Coke, Sprite, a variety of juices and other drinks bottles need to do PET shrink film sealing label accompanying shrinking film plant, they belong to the same class of polyester, is Environment-friendly materials, easy Recycling. Shrink film sealing, red plastic (certified), shrink film is provided by Xiong Red Plastic Factory.
