Ternary polymer blended films were prepared by mixing different weight percent of papain in equal weight percent solutions of poly (vinyl alcohol) (PVA) and chitosan (CS) by solvent evaporating technique. The phase morphology and mechanical properties of various polymeric blended films were carried out using scanning electron microscopy (SEM) and universal testing machine (UTM) at room temperature. SEM micrographs for the blend system showed good miscibility among the blend components. The tensile strength increases with increase in wt% of papain (dried papaya latex in power form) and then decreases.
