Product Description

Eastar™ GN007 Copolyester is a water-clear glycol modified polyethylene terephthalate (PET) with an added mold release. Eastar™ GN007 copolyester will not crystallize and thus offers wider processing latitude than conventional crystallizable polyesters. This material offers an excellent combination of clarity, toughness, and melt strength that makes it useful for a variety of processing techniques and end-use applications. This makes this product one of our most versatile materials for the cosmetics and personal care packaging market.
