Generally, a plastic with a high degree of toughness is desired in food packaging application. The plastic which is able to resist any breakage under tensile strength is preferred. These can be achieved by exert the plastic films with the characteristics like high tensile strength and high degree of elongation. A packaging material or plastic material which is brittle in natures, and with poor tensile strength and flexibility will have a minimal use in food packaging industry. Basically, tensile
