PET- Polyethylene Terapthalate films are widely used by Color Labs and Printing Industry both. They offer high thermal stability and tensile strength. In terms of mechanical properties, such as modulus and tensile strength, PET typically outperforms BOPP. Basically, PET is well suited for applications requiring a strong film with high tensile properties, scuff resistance, and durability. … By comparison with PET, BOPP film offers an improvement in moisture barrier.
