Classification according to the use of polyester film (2)-film supplier
4. PET universal film has excellent strength and dimensional stability, cold resistance and chemical stability, and is widely used in various substrates such as composite packaging, photosensitive film, metal evaporation, audio and video. Specifically, there are the following: ① Semi-reinforced membrane. The main feature is that it has high longitudinal tensile strength and is not easy to break under high tension. It is mainly used for packaging seals for boxed items. Commonly used standard thicknesses are 20μm, 28μm, 30μm, 36μm, 50μm, etc. ②Foil stamping film. The biggest feature is good tensile strength and transparency, stable thermal performance, and low binding force with certain resins. It is mainly suitable for small dimensional changes during high-temperature processing or as a transfer carrier. The conventional standard thickness is 9μm, 12μm, 15μm, 19μm, 25μm, 36μm and so on. ③Printing composite packaging film. The main features are good transparency, good penetration resistance, superior chemical resistance, temperature resistance and moisture resistance. It is suitable for the packaging of frozen food and food, medicine, industrial products and cosmetics. Commonly used standard thicknesses are 12μm, 15μm, 23μm, 36μm, etc. ④ Aluminized film. The main characteristics are high strength, good temperature and chemical resistance, good processing and anti-aging properties, and proper corona treatment, which makes the adhesion of the aluminum layer and the film stronger. After being used for aluminum plating, it can be widely used in food packaging bags such as tea, milk powder, candies, biscuits, etc., and can also be used as decorative film such as flower crafts, Christmas trees and other decorations; at the same time, it is also suitable for printing composite bags or cardboard composite bags And other packaging films. Conventional standard thicknesses are 12μm, 16μm, 25μm, 36μm and so on. ⑤ Magnetic recording film. It has the characteristics of good dimensional stability, uniform thickness and high tensile strength. Suitable for base film and special packaging film of magnetic recording materials, including audio and video tape base (commonly used standard thickness is 9-12μm) and black film (commonly used standard thickness is 35-36μm). 5. Nano-level PET film a. High transparency and gloss: The particle size of nano particles is between 1-100nm, which is smaller than the wavelength of visible light, which has little effect on the transparency of the film. b. High barrier performance and heat resistance: the use of nanomaterials with special properties and unique processing technology to make the nanomaterials uniformly dispersed in the PET matrix in nanometer size, and stretch the orientation during the film production process, thereby making the PET film appear Excellent barrier properties, the permeability of O, CO2, H2O and other substances has been doubled down, and the heat resistance has also been greatly improved. Based on its characteristics, it has expanded the application field of PET, greatly extended the shelf life of the packaged goods, and can also be used in hot filling or sterilization industries. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
