It is a kind of Amorphous copolyester. The material has high transparency, high impact resistance, high hardness and good low temperature toughness. It is widely used in the fields of sheet material, high-performance shrink film, profiled materials, toys, food, high-grade packaging materials, etc.

    PETG has been used more and more in the card industry because of its lower filling temperature (about 100%), higher mechanical strength and excellent flexibility, higher transparency than PVC, good gloss, and easy Printing and has environmental advantages.

    In Europe, the United States, and Elben, PETG materials are widely used in electronic payments and identification documents. Visa has recognized PETG as its card base material. Some domestic high-end cards and important legal documents have begun to use PETG as card base materials.

    The main manufacturers of PETG resin in the world are Eastman and SK. Manufacturers of card-based materials purchase PETG resin and formula through calendering or casting to add T into plates, sheets, films, etc. There are currently four domestic manufacturers of PETG materials, all of which use imported Eastman The resin produces card-based materials.
