Ternary polymer blend films of poly (vinyl pyrrolidone) (PVP) doped poly (vinyl alcohol) (PVA)/chitosan (CS) blend films were prepared by solvent casting method. In this study, films containing different concentration (wt %) of PVP and equal quantity of CS/PVA (50/50) were characterized. With increase in the concentration (wt%) of PVP into the equal quantity of CS/PVA, blend shows slight increase in tensile strength and significant increase in elongation at break and decrease in young’s modulus.
