Guar gum doped chitosan (GG/CS) films prepared by solvent casting method. The tensile properties of fabricated films containing different concentration (wt %) of GG/CS were characterized using universal testing machine (UTM). As concentration of GG increases, tensile strength and young’s modulus decreases and elongation at break increases compared to pure CS film. The structural morphology of GG/CS films were studied using scanning electron microscope (SEM). The SEM micrograph of the pure CS shows smooth and homogeneous surface with some straps on the top surface and GG/CS films shows smooth surface with reduced straps on the top surface.
