The present study aimed to prepare film from chitosan by three treatment (D, C and B) with glycerol plasticizer (without added glycerol,15 and 30%) from weight chitosan was used to prepare edible film it was also noticed thickness increased film B from 0.044- 0.048 mm the and C from 0.042 to 0.046 mm and D from 0.040 to 0.044 mm and water vapor permeability values increased from 11.78-13.59 and from 10.32-12.23 and from 10.28- 12.94 g.mm /m2.hr.kpa.

the film D, C and B respectively with increased glycerol concentration whereas tensile strength decrease with increased glycerol added and all films prepared accompany increase elongation percentage the films prepared but water solubility the films it increase with increased glycerol added reach for high rate in film D 24.35%.

Effective aggregates also diagnosed chitosan film and at the same time as the thermal decomposition weighted in which showed several stages film of the disintegration of the start of the 100 °C and ends at a temperature of 558 °C as the molecular structure of X-ray appearance of semi- form amorphous film chitosan through the emergence of two peaks at an angle 2
