Different concentrations of PVA blended Gelatin were taken for grafting under γ-radiation. Better grafting means better cross-linking of polymer. We observed the effect of concentration of polymers and the effect of radiation doses. Various physico-mechanical and morphological properties like tensile strength (TS), elongation at break (Eb), FTIR, Scanning Electron Microscopy (SEM) of films were observed. For untreated (virgin) Film, radiation doses were optimized for such types of properties. By casting process Gelatin-based polyvinyl alcohol (PVA) films were prepared in different ratios. These films were irradiated under gamma radiation (60Co) at different doses (0.5-5 kGy). The mechanical properties of these films were evaluated. It was found that 95% gelatin +5% PVA film exhibited the highest tensile strength (TS) value at 0.5 kGy gamma radiation (51 MPa), which was 46% higher than that of nonirradiated films.
