This study was conducted to extract cellulose and synthesis carboxymethyl cellulose from flour bran. Fourier Transform Infrared Spectrometer (FT-IR) was used to confirm the existent of the carboxymethyl group. The sample edible films were prepared using 1, 2, 3, and 4 % CMC, and two types of plasticizers glycerol and sorbitol, (20, 40 and 60) %. Their qualitative, mechanical, reservation and thermal characteristics were studied. Tensile strength ranged 28-51.3 MPa and elongation percentage ranged between 65.5-91.0 %. The thickness of simple cellulose films were 0.018-0.078 mm. The values of solubility (19.05-36.31%) and the permeability values of simple cellulose film increased with the increasing of the plasticized ratio. The highest permeability was 11.99 g.mm/m2.h.kp at 60% glycerol and thermogravimetric analysis for some simple cellulose film plasticized by glycerol were 135, 146.29, 125 and123.23° C.
