What is polyester film?
Polyester is a versatile plastic film that excels in having an exceptional combination of optical, physical, mechanical, thermal, and chemical properties. Polyester is also known as Biaxially Oriented Polyethylene Terathalate (BOPET). The name “PET” is the common abbreviation for the chemical name “polyethylene terephthalate”.
