Abstract:  Dual modified starch films were prepared by using crosslinked-oxidized starch via hydrogen peroxide and different crosslinking agents, including borax and a mixture of sodium trimetaphosphate/ sodium tripolyphosphate. The effect of different crosslinking agents on the properties of dual modified films was examined and compared to single modified starch films. The crosslinked and oxidation reactions were confirmed by diminished intensity peaks of hydrogen bonding and new IR peaks of carbonyl and carboxyl groups. Tensile strength and hydrophobicity of native starch film, and elongation of crosslinked starch films were improved by crosslinked-oxidized method, especially for crosslinked starch film with borax.
