摘要：
Thin gelatin films (about 0.25mm thickness) were prepared from granular gelatin via casting. The mechanical properties of gelatin films such as tensile strength (TS), elongation at break (Eb%), water uptake and water aging properties were investigated. To improve the water aging properties of gelatin films, gelatin-glucose and gelatin-urea films were prepared. Effect of gamma radiation on the tensile properties, water uptake and water aging properties of gelatin-glucose and gelatin-urea films were also studied. The results of the investigation show that both glucose and urea can improve the water stability of the gelatin films.
