The results showed that adding different ratios of FG (20-50%) to the control film (50CMC/50PVAG:0FG) significantly reduced the solubility and tensile strength of the films, as the 25CMC/25PVA:50FG ratio has the lowest values; also, the moisture content, contact angle, whiteness index, water vapor permeability (WVP) and elongation at break (EAB) of the films showed a significant increase compared to the control (p < p >The present study was aimed to investigate the physical and mechanical properties of biodegradable ternary films based on carboxymethyl cellulose (CMC), polyvinyl alcohol (PVA) and fish gelatin (FG) at different ratios (50CMC/50PVAG:0FG, 40CMC/40PVA:20FG, 35CMC/35PVA:30FG, 30CMC/30PVA:40FG and 25CMC/25PVA:50FG) via a simple casting method.
