材料文字说明

Eastar™ GN071 copolyester is a clear copolyester used in a variety of packaging and consumer product applications, including food and beverage packaging, general-purpose packaging, flexible film packaging, and consumer products. It is among the easiest resins to extrude into thin films and rigid, thermoformed containers.

Eastar GN071 enables fast-moving consumer goods brand owners to make high-quality packaging and replace materials of concern while providing the premium appearance consumers expect. Packaging converters prefer Eastar GN071 for its best-in-class processing ease, energy efficiency, thermoformability, and versatility.
