Abstract

This study examines the degradation of starch-based biodegradable films under UV radiation, focusing on their mechanical properties. Tensile strengthand elongation were measured afterdifferent UV exposure durations. Results show a decrease in both properties, indicating material degradation, emphasizing the necessity for further research to enhance the stability of these films.

Keywords (in English)
