Chemical stability of PET polyester film-film supplier
PET polyester 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. The main feature of semi-reinforced film is that it has high longitudinal tensile strength and is not easy to break under large tension. It is mainly used for packaging seals for boxed items. Commonly used standard thicknesses are 20μm, 28μm, 30μm, 36μm, 50μm, etc. 2. Bronzing 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. 3. Printing 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. 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.
