Description

Akestra™ 100 is an amorphous copolyester with sparkling glass-like clarity suitable for food packaging containers, sheets and films as well as in durables. It has outstanding features in heat resistance, chemical resistance and hydrolytic stability. Akestra™ has excellent processing properties, is easy to process in standard PET equipment and can be used in most polymer processes like extrusion casting and coating, injection molding. The high melt strength also enables good processability in film blowing and blow molding.

Akestra™ 100 is compatible with PET and can be coextruded with PET and used in thermoforming of cups for hotfill as a sustainable replacement for PS. Akestra™ may be used in food contact application and complies both with FDA and EU regulations for direct food contact.
