All modified starch films were oxidized and crosslinked using hydrogen peroxide and boric acid by casting technique. Degree of crystallinity and swelling behavior of both dual-modified starch films were found to decrease. Moreover, O-CS film showed smoother fractured morphology than C-OS and NS films. Both C-OS and O-CS films presented not only high stress at maximum load and Young's modulus but also high strain at maximum load, as compared to single-modified film. Furthermore, water vapor permeability, thermal property and biodegradability of all modified films were also studied.
