Problems solved by technology

[0002] PETG is a non-crystalline copolyester. Its products are highly transparent, have excellent impact resistance, and excellent processing and forming properties. They can be designed in any shape according to the designer's intention. Traditional extrusion, injection molding, and blow molding can be used. And molding methods such as blister, can be widely used in markets such as plates, sheets, high-performance shrink films, bottles and profiled materials, but most of the existing PETG heat shrinkable film production methods have complex production processes, low production efficiency, and low quality. Poor, unable to meet production needs
