Randomized trial demonstrates enhanced mechanical and antibacterial properties in bioplastic films using potato peel starch, indicating their potential for sustainable packaging.
Key Points
This research focuses on developing biodegradable bioplastic films from potato peel starch blended with PVA and reinforced with MCC and chitosan.
Films were synthesized through solution casting with varying MCC contents.
Density, tensile properties, thermal stability, morphology, antibacterial activity, and biodegradability were characterized.
FTIR analysis was conducted to evaluate hydrogen bonding among components.
Increased MCC content improved film compactness and tensile strength, with strong interfacial interactions.
Thermal analysis indicated enhanced resistance to degradation of the films.
Bioplastic films displayed antibacterial activity against Staphylococcus aureus and Escherichia coli, especially at higher MCC loading.
