PET film or PolyEthylene Terephthalate film is a thermoplastic polymer. Like most thermoplastics, PET films can be biaxially oriented (BOPET film), bubble extruded, and co-extruded (co-extruded PET film). Polyester film is one of the most common substrates used in the converting industry because of its balance of properties in relation to other thermoplastic polymers
