Films were prepared using the casting method from enset starch, as a filler material, glycerol & sorbitol as plasticizers at different concentrations (15, 25, and 35%). And glucose, fructose, and sucrose were added to enhance flexibility. The films were characterized and compared with the effect of plasticizer type (glycerol and sorbitol) and the concentration of some physicochemical properties of ES-based films. The films were analyzed for moisture content, film density, and thickness, swelling capacity, tensile strength, and percentage elongation. The study indicated that moisture content, film thickness, film density, swelling capacity, tensile strength, and percentage elongation are dependent on the type of plasticizer and its concentration. Increasing the plasticizer concentration from 15 to 35 % increases moisture content, and film thickness; decreases the film density, water swelling capacity, and tensile strength of films, regardless of the plasticizer type used.
