Abstract Active and eco-friendly bionanocomposite films were developed using plasticized cellulose acetate butyrate (CAB) as the matrix. Silver nanoparticles doped-zeolite (AgZ) and thymol (Th) were incorporated at varying concentrations to serve as antibacterial and antioxidant bioactive components, respectively. The results revealed the formation of silver nanoparticles (AgNPs) within a zeolite framework with a face-centered cubic crystalline structure. While the films containing AgNPs showed a slight decrease in transparency, they exhibited significantly improved UV-blocking properties, and reduced water solubility and water vapor permeability mostly in M/AgZ5%/Th2% film prepared at 5% and 2% of AgZ and Th, respectively. Furthermore, both additives improved the wettability of film surfaces. Th-included films presented antioxidant activity and those with AgZ displayed antibacterial effects against pathogenic bacteria. Packaging tests confirmed the ternary films effectiveness in extending the shelf life of strawberries and shrimp. Thus, the proposed active films offer great potential for enhancing food safety through packaging.
