PETG film is a high performance transparent copolyester film made by copolymerizing ethylene terephthalate (PET) with some 1,4-cyclohexanedimethanol (CHDM). This unique chemical structure endows PETG films with excellent physical properties and broad application potential. It not only inherits the high transparency, good mechanical strength, and chemical resistance of PET film, but also improves its processing performance and thermal shrinkage by introducing CHDM, becoming one of the favored packaging materials in the market.
