The materials, equipment, and processes used in the metal stamping industry have proven to be less costly than the original methods of forming metals and alloys into definite shapes. Metal stamping is the method of bending, clipping, and molding sheet metal or coil metal by stamping and pressing the material into the desired forms. The shaped metal is plated with nickel, tin, or some other metallic elements to protect it from corrosion. The most commonly used metals are steel, aluminum, zinc, and

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
