Abstract Consumer demand warrants improved efficacy and environmental impact of food packaging modalities. Here, multifunctional biodegradable films were prepared using 10, 20, and 40 wt% sodium metabisulfite (SM) as an active compound along with polycaprolactone (PCL). Increased SM content significantly affected film oxygen scavenging, antioxidant, anti-browning, and antimicrobial properties (p
