Polyester film (PET) polyester film is a polyethylene terephthalate as raw pe packaging film, using extrusion method into thick slices, then by two-way stretch film material. It is a colorless, transparent, glossy film pe packaging film wire and cable, excellent mechanical properties, high stiffness, hardness and toughness, puncture resistance, abrasion pe packaging film manufacturer, high temperature and low temperature pe packaging film manufacturers, resistance chemical resistance, oil resistance, air tightness and preserving flavor is good, it is one of the barrier composite film substrates commonly used. But higher prices of polyester film, generally a thickness of 12 μ m, often used for cooking and outer packaging materials, printing better. . The main measures to prevent the film negative corona corona treatment is to regulate the rubber roller before pinch roller pressure, pressure on both ends of the pinch roller and the pressure must be the same size but also appropriate. In addition, the corona roller and a pinch roller must be rigorous static and dynamic balance test, runout requirement is less than 0.05 mm, the purpose is to ensure the smooth plastic film roll into the corona, to prevent the clip into the air, thus avoiding the occurrence of negative corona phenomenon . pe packaging film wire and cable, Bayannao'er pe packaging film, Red Plastic Factory Xiongxian provided by Red Plastic Factory.
