PVP/PVA blended hydrogels as a biofilm for use in food packaging applications

Bio-films have been produced that attract attention with their functional behavior among conventional food packaging materials of bio-based polymer blends. The physical and morphological properties copolymeric biofilms extensively investigated. Biodegradable copolymer films were by in situ polymerization technique prepared as solution casting. strong water absorbency polyvinyl alcohol the antimicrobial property polyvinylpyrrolidone are combined a single material. Structural characterized Fourier-Transform Infrared Spectroscopy Scanning Electron Microscope analysis. These results show obtained can be used an environmentally friendly blend material to extend shelf life products.
