Estimation of resistance of starch/polyvinyl alcohol blends to permeation by organic solvents

► Corn starch, glycerin and PVA were blended to prepare the starch/PVA samples. ► The addition of starch may result in enhancing the degradation rate of the blends. ► Tensile strength and chemical resistance were decreased with an increase in starch. ► The solvent with a large molecule size or low polarity is less permeable in samples.
