Tensile Strength (TS) for gelatin film significantly
increased with growing irradiation doses (improved by 30% for 60 kGy), but the TS of chitosan and blend
films were not significantly affected. On the contrary, irradiation significantly reduced elongation at
break (%E) for chitosan and blend film up to 50% whereas it twice increased the Young modulus. Moisture
barrier efficiency (30e84% RH gradient) of blend films was slightly improved after irradiation
