PETG in Plastic Packaging

PETG (Polyethylene Terephthalate Glycol-modified) packaging materials face increasing scrutiny due to their persistence in the environment. While PETG offers excellent clarity, impact resistance, and processing characteristics at temperatures between 230-250°C, its non-biodegradable nature poses significant environmental challenges when compared to emerging sustainable alternatives.

The fundamental challenge lies in developing biodegradable alternatives that match PETG's mechanical properties and processing convenience while ensuring complete breakdown in natural environments.

This page brings together solutions from recent research—including PLA-PHB crosslinked blends, polyester compositions with aromatic-aliphatic combinations, and novel PET-PGA materials with enhanced degradation properties. These and other approaches focus on achieving the balance between material performance and environmental responsibility in modern packaging applications.
