Material Notes:
Eastar GN002 Copolyester is a glycol modified polyethylene terephthalate (PET) with an added mold release. Eastar GN002 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.Applications/UsesBlister packaging
