Universal film. With excellent strength and dimensional stability, cold resistance and chemical stability, are widely used in composite packaging, photographic film, metal evaporation, audio and video recordings and other substrates. There are several specific types of the following:
① semi-fortified membrane. The main feature is the longitudinal tensile strength, under the larger tensile force is not easy to break, mainly used in boxed items packaging seals. Common standard thickness has 20μm, 28μm, 30μm, 36μm, 50μm.
② bronzing Film. The biggest characteristic is the tensile strength and the transparency is good, the thermal performance is stable, with certain resin's binding force is lower. It is mainly suitable for the use of small size change or as transfer carrier during high-temperature machining. The conventional standard thickness is 9μm, 12μm, 15μm, 19μm, 25μm, 36μm.Polyester Film
③ Printing Composite Packaging film. The main features are good transparency, excellent penetration resistance, excellent chemical resistance, temperature and moisture resistance. Apply to frozen food and food, medicine, industrial products and cosmetics packaging. Common standard thickness is 12μm, 15μm, 23μm, 36μm.Polyester Film
④ aluminized Film. The main characteristics are high strength, mild resistance to chemical performance, good processing and anti-aging performance, appropriate corona treatment, so that the aluminum layer and film adhesion more firmly. Used for aluminum plating, can be widely used in tea, milk powder, candy, biscuits and other packaging, can also be used as decorative film such as bine crafts, Christmas trees; Conventional standard thickness is 12μm, 16μm, 25μm, 36μm.Polyester Film
⑤ Magnetic recording film. It has the advantages of good dimensional stability, uniform thickness and high tensile strength. It is suitable for the base film and special packing film of magnetic recording material. Includes audio tape base (common standard thickness has 9-12μm) and black film (common standard thickness is 35-36μm).Polyester Film
