The present study was carried out to investigate the preparation of chitosan-Ag nanocomposite filmfor food packaging. Since chitosan is a suitable alternative to produce packaging films due to favorablefactors such as biodegradability and abundance in the world, therefore in this study, it was preparedchitosan-Ag nanocomposite with antibacterial properties for food packaging b...
