Food packaging films that show post-consumer biodegradability are rarely explored by researchers. The present study was carried out to investigate the physicomechanical characteristics of ethyl cellulose (EC) based films to be used in food packaging. Ethyl cellulose was plasticized with different percentage of polyethylene glycol (PEG). The samples of standard dimensions were subjected to different testing such as soluble matter content, moisture content, oil permeability, surface morphology, mechanical testing etc. The data obtained was analysed to decide the moderate percentage of plasticizer that can be used to provide a rational explanation of a perfect quality specimen. It has been revealed that too high or too low percentage of plasticizer was not appropriate for a good film. Tensile stress analysis was used to estimate the mechanical properties of the films. The results have shown an increase in tensile properties with increase in coalescence temperature. Temperature-dependent plastic deformation was observed for coalescence temperatures above 50oC.
