Biodegradable Starch Based Film for Food Packaging

Recent developments in starch-based materials encompass both fundamental research and applied innovations. While pure starch is biodegradable and an excellent film-forming polymer, it lacks the tensile strength and moisture resistance needed for practical packaging. Microbial contamination is a significant concern in food packaging; thus, enhancing barrier properties and antimicrobial activity is essential. In this study, we developed a biodegradable starch-based film by blending 6% corn starch, 3% glycerol, 0.5% peppermint oil, and 1% cellulose. The mixture was homogenized at 90°C and dried at 50°C to produce films with improved antimicrobial and mechanical properties. Characterization of the films included mechanical, barrier, and biodegradability tests, with promising results supporting their potential for sustainable food packaging applications.
