The present study reports the synthesis of antibacterial biodegradable nanocomposite film of poly (vinyl alcohol)-biogenic silver. The biosynthesized silver nanoparticles were used for development of nanocomposite film. Ficus benghalensis leaf extract was used to synthesize silver nanoparticles which are cost effective, environmental friendly and rapid method. The PVA-biogenic silver nanocomposite film was characterized by AFM to determine the morphology of the film surface and confirm the incorporation of silver nanoparticles. The antibacterial activity of the nanocomposite film was investigated against Salmonella typhimurium by means of disk diffusion method. PVA-biogenic silver nanocomposite film shows excellent antibacterial activity against Salmonella typhimurium. This nanocomposite film can be a prominent material for food packaging
