Abstract:
Polylactic acid/chitosan blends with bio-released Ag nanoparticles nanocomposite films were prepared for eco-friendly food packaging materials. These food packaging materials were prepared to enhance the biodegradability of packaging materials as well as to increase the shelf life of food products against microbial action. The preparation was made by dissolving PLA and chitosan using suitable solvents with PEG 400. To this, blend silver nanoparticles obtained from Tulsi leaves extract were added and homogenized. PLA/chitosan blend with Ag-NPs was prepared and characterized for their spectral, morphological, and antimicrobial properties. The spectral and morphological studies showed the blending of PLA/chitosan as well as Ag nanoparticles in the nanocomposites. The antibacterial activity of the PLA/chitosan/AgNPs nanocomposites (PCAg) showed a greater inhibitory effect against Staphylococcus aureus and also against Escherichia coli.
