Degradation of PBS and PET Under Processing Conditions

Polybutylene succinate (PBS, 51% bio-based) andpolyethylene terephthalate (PET, 20% bio-based) were developed into films via thermocompression. Crystallinity was analyzed using Differential Scanning Calorimetry (DSC), while mechanical properties were evaluated through tensile tests. The influence of aging was studied by varying thermocompression conditions, such as compression times and temperatures, followed by re-evaluation of thermal and mechanical properties. This work provides insights into the relationship between microstructure and mechanical behavior, contributing to the optimization of PBS, PET, and PEF films for sustainable packaging applications.
