What is BOPET film? What are its characteristics?

BOPET film is a biaxially oriented polyester film. BOPET film has the characteristics of high strength, good rigidity, transparency, high gloss, etc.; Global Plastics believes that it has no odor, high toughness, high toughness, and excellent toughness; its tensile strength is 3 times that of PC film and nylon film, and its impact strength is 3-5 times that of BOPP film. It has good wear resistance, folding resistance, pinhole resistance and tear resistance, etc.; it has low heat shrinkage, and only shrinks by 1.25% after 15 minutes at 120°C; it has good antistatic properties, is easy to vacuum aluminum, and can be coated with PVDC, thereby improving its heat sealing, barrier and printing adhesion; BOPET also has good heat resistance, excellent resistance to cooking, resistance to low temperature freezing, good oil resistance and chemical resistance, etc.

Except for chloroform and benzyl alcohol, BOPET film cannot be dissolved by most chemicals. However, BOPET will be corroded by strong alkali, so be careful when using it. BOPET film has low water absorption and good water resistance, and is suitable for packaging foods with high water content.
