Abstract

Biopolymer films with antimicrobial properties are gaining significant attention in the food packaging industry due to their potential to extend the freshness and shelf life of perishable products. These films, derived from natural polymers such as starch, chitosan, and cellulose, offer a sustainable alternative to conventional petroleum-based plastics. By incorporating antimicrobial agents such as essential oils, plant extracts, or metal nanoparticles into the biopolymer matrix, these films exhibit enhanced microbial resistance, effectively inhibiting the growth of spoilagecausing bacteria, fungi, and molds. This paper explores innovative approaches in the development of biopolymer films with antimicrobial properties, discussing advancements in film formulation, the selection of antimicrobial agents, and their impact on food safety and quality. Furthermore, the challenges associated with scalability, regulatory approval, and consumer acceptance are addressed, while the potential applications of these films in various food products, including meats, dairy, fruits, and vegetables, are examined. The future outlook for biopolymer films in food preservation and their role in reducing food waste and environmental impact is also highlighted.
