Abstract

In this paper, polyvinyl alcohol (PVA) /Corn Starch (CS) blend films were prepared using the solution casting method by changing the blending ratio of starch/PVA. The effects of gamma irradiation and soil burial on the biodegradability of the tested films were investigated by the mechanical properties (tensile strength and elongation to break %) and the determination of weight loss. Nevertheless, the results from the tensile strength and elongation at break tests showed that as the CS content increased, the strength decreased. After irradiation, the tensile strength and elongation to break of the films were improved the blends due to the crosslinking caused by the chemical reactions between starch macromolecules under the action of ionizing radiation. Finally, It was noticed that the weight loss increases with increasing of CS content.
