The mechanical properties (TS and %E) and WVP of the rice starch film, modified rice starch films and various films were compared ( Table 7). The DMRS films had greater both mechanical properties and water vapor barrier than NRS films. This indicated that the DMRS films from this study were successful for improvement the properties of native rice starch film. Therefore the characteristics of the modified rice starch films were compared with those of other biopolymers and synthetic polymer films in order to evaluate their quality for further applications.
