The subject of the research nanocomposite film materials obtained by sputtering and bulk introduction of metal nanoparticles into a polymer matrix. The purpose of the research development of a technology for obtaining and welding packaging materials with effective antimicrobial action for high-quality and safe storage of food products based on environmentally friendly materials – biopolymers of polylactide (PLA), polyhydroxybutyrate (PHB) and polycaprolactone (PCL) and Ag, Zn, ZnO, Ag/Zn or Ag/ZnO nanoparticles. Research methodology formation of nanocomposite film materials, research of their structure and properties. Results and their novelty. Film materials based on PLA, PHB, PCL biopolymers were developed by spraying and bulk introduction of Ag, Zn, ZnO, Ag/Zn or Ag/ZnO nanoparticles into the polymer matrix. A correlation was found between the formation, welding, structure and properties of the samples. The bactericidal activity of the created materials was revealed against the microorganisms Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa. It was established that the developed samples do not exhibit a genotoxic effect. The inhibitory effect of packaging film materials on meat and bakery products and plant raw materials was revealed. It was established that biopolymer packaging materials with bactericidal properties allow to increase the shelf life of food products based on meat and bakery products and plant raw materials.
