Product Description

Eastar™ copolyesters are brilliantly clear polymers that have excellent impact strength, chemical resistance, dimensional stability, and low shrinkage rates. Eastar™ DN004 copolyesters are the toughest materials for the cosmetics and personal care packaging applications. It's very shatter resistant and offers excellent chemical resistance. DN004 contains a mold release.

The GREENGUARD INDOOR AIR QUALITY CERTIFIED Mark is a registered certification mark used under license through the GREENGUARD Environmental Institute (GEI). GEI is an industry-independent, non-profit organization that oversees the GREENGUARD Certification Program.
