Plastic substitute material with biodegradable vegetable plastic in the form of edible film is an alternative material for vegetable plastics that can decompose naturally. The raw material for an edible film consists of corn cob flour and a mixture of plasticizers in the form of glycerol and sorbitol. The process of mixing edible film raw materials by means of dispersion, heating, printing, and drying. Variable corncob flour is 5-9 grams and the ratio of plasticizer glycerol-sorbitol is 0.25-4. These characteristics incorporate the esteem of malleable quality with the biggest esteem of 0.536 MPa and the littlest 0.066 MPa. The esteem of elongation with the biggest esteem of 21.4% and the littlest 4.1%, film thickness with the biggest esteem of 0.26 mm and the littlest esteem of 0.12 mm, and water vapor penetrability with the biggest esteem of 11.83 gr/m2 day and the littlest 8.86 gr/m2 day. The most excellent consumable film comes about was gotten at the proportion of glycerol-sorbitol plasticizer 1.0 and 7 grams of corn cob flour. Based on the characteristics of tensile strength, elongation, film thickness, and water vapor permeability, the results obtained to the requirements of edible films, but are still below the requirements of the Japanese Industrial Standard (JIS).
