industrial packaging film, pharmaceutical and food packaging film, mechanical parts, daily necessities, building materials, wires, cable insulation, coating and synthetic paper. (2) low-pressure high-density polyethylene (HDPE) crystallinity of 80% to 90%, density, the use of high temperature, hardness and mechanical strength of large, good chemical resistance. Uses: the use of injection molding, blow molding, extrusion, rotomolding and other molding methods, the production of film products, daily necessities and industrial

Various sizes of hollow containers, pipes, packaging with the rolling belt and ligation, rope, nets and weaving with fiber, wire and cable.
????(3) linear low density polyethylene (LLDPE) LLDPE and LDPE due to the molecular structure is significantly different performance is also different. Compared with LDPE, LLDPE has excellent resistance to environmental stress cracking performance and electrical insulation, high heat resistance, impact resistance and puncture resistance Uses: through injection molding, extrusion, blow molding and other molding methods, production film, , Pipe, wire and cable Second, polypropylene (PP)
Is the lightest plastic in a light, the only can boil in the water,
No solvent at room temperature can make polypropylene dissolved Use: film is mainly used for packaging clothing, knitwear, food, cigarettes and so on. Hollow molded articles include containers, bottles of polystyrene (PS) and K-resin. Polystyrene (PS) is a hard, brittle, transparent, amorphous thermoplastic. No smell, burning black smoke; easy to dye and processing, low moisture absorption, dimensional stability, electrical insulation and thermal insulation performance Excellent use: daily life of the common application of a variety of disposable plastic tableware, transparent CD box Wait
Second, K-resin
??Is a high degree of transparency and good impact resistance, low density, strong coloring, excellent processing performance, non-toxic Uses: Drink cups, salad plates, cooked dish and lunch boxes with membrane hinges and other polyvinyl chloride ( PVC) and polyvinylidene chloride (PVDC) First, polyvinyl chloride (PVC) is a non-toxic, odorless white powder, the higher the molecular weight of the polymer, mechanical properties, cold resistance, thermal stability, but the higher Processing more difficult to join the plasticizer, reduce the plasticizing temperature, and make it soft Uses: mineral water, beverages, cosmetic bottles, there are also used for refined oil packaging Second, polyvinylidene chloride (PVDC)
??For a lot of gas and solution has a very low transmittance in the heat, ultraviolet, ionizing radiation, alkaline reagents, catalytic metal
