Chitosan films were prepared using four types of chitosans with different molecular weight and the effect of molecular weight of chitosan on select ed film properties such as color , water vapor permeability (WVP), water solubility (WS), tensile strength (TS), and elongation at break (E) was investigated. Generally , the total color difference (ΔE) and WS of the films decreased, while T S and E of the films increased as molecular weight of chitosan increased. WVP of the films did not show any significant relationship with molecular weight of chitosan.
