Protein based edible films are attractive for food application because of their high nutritional quality, excellent sensory properties, and good potential to adequately protect food products from their surrounding environment. Such films act as a carrier of antioxidant, flavor, and bacteriostats and can improve the quality of food products. Protein based films have received considerable attention in recent years because of its uses in edible and nonedible packaging materials. The proteins such as soybean , corn , wheat , peanut , and sunflower seed  etc., as well as gelatin from collagen  and milk proteins (casein and whey proteins)  are appropriate for the production of edible film because of its nutritional properties as aforementioned. Several globular proteins, including gluten , corn protein , soy protein , and whey protein  etc., have been investigated for their film properties. Protein based edible films have impressive gas barrier properties as compared with those prepared from lipids and polysaccharides . When they are not moist, the O2 permeability of the soy protein film was 500, 260, 540, and 670 times lower than that of low density polyethylene, methyl-cellulose, starch, and pectin, respectively . Several researchers studied the application of protein based edible films in food use [85, 86] and they reviewed the applications of protein films, such as soy protein film, casein emulsion film, whey protein film, and corn-zein films on nut and fruit products. The polymeric characteristics of the protein film have been used for edible food packaging application [45, 72, 81, 87, 88] but for nonfood packaging application the major problems are an advance of mechanical properties (such as toughness, strength, and elasticity, flexural, shear strength, tensile modulus, etc.). The step head blends of protein and nonprotein molecule have been prepared with improved mechanical properties [26, 89-92]. Massive chances still exist to create a new kind of blends with new characteristics, which could be used for both food and nonfood packaging.
