- Abstract
This article presents the results of a study on the potential of microbially degradable poly‑3‑ hydroxybutyrate P(3HB) synthesized from waste fish oil (WFO) for the production of food packaging films. A technology for manufacturing single- layer films was developed using flat- slot extrusion of a polymer melt with a laboratory- scale Brabender E19/25 D extruder. Batches of film samples were produced and subjected to comprehensive testing in accordance with the current GOST standards in the Russian Federation and international ISO standards. The study evaluated the films’ physico-mechanical properties, structure, surface characteristics, moisture and vapor permeability, resistance to liquid environments, and antibacterial activity against microflora associated with meat and dairy products. The experimental samples were found to meet the requirements for food packaging films, demonstrating suitability for practical applications in this field
