PE polyethylene, which is transparent thermoplastic. PE commonly used in three categories, namely: LDPE HDPE LLDPE three kinds of polyethylene monomer is the same, but in the synthesis of these polyethylene, the process conditions used are not the same, therefore, only the generation of three different polyethylene varieties, three kinds of materials have a greater difference in performance.
PE film is a good toughness of the material, not easy to use ordinary plastic shredder crushing. Because the PE film is soft and tough, it is not easy to chop, not to mention the high speed of the tool temperature, will make LDPE melt adhesion to the blade. PE granulation, can be directly into a strip into the extruder feeding port, by the shear force of the screw to drag the PE film into the barrel heating melt extrusion granulation. PE Recycled primary materials, still can blow film, used in non-food and pharmaceutical packaging, but also widely used in the production of Oxford leather and waterproof cloth, the future is bright.
PE heat Shrink film Application
PE heat Shrink film is widely used in alcohol, cans, mineral water, a variety of beverages, cloth and other products of the whole set packaging, the product flexibility, impact resistance, tear resistance, not easy to break, not afraid of moisture, shrinkage rate is large.
PVC heat Shrink film Application
PVC shrink film, plus ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, the lowest layer is the back coating adhesive. It is a well-loved, popular and widely used synthetic material in the world today. PVC is the most suitable material in materials that can produce three-dimensional surface membranes.
Because of the unique properties of PVC (Rainproof, Refractory, antistatic, easy to form) and PVC low input high yield characteristics, is widely used in the building materials industry and packaging industry, therefore, PVC film has high transparency, good gloss, high shrinkage characteristics.
