Abstract

Previous studies show that synthetic plastic has more disadvantages than bioplastic such as high cost and higher environmental risk. Recent studies tend to concern towards the environmental issues. The use of starch based TPS films act as an alternative synthetic plastic competitor. The aim of this project is to study the suitable composition of corn and tapioca starch as bio plastic materials and the properties of corn and tapioca starch based TPS as bio plastic materials. Corn and Tapioca starch is usually mix with glycerol and the composition that being selected is 70TPS/30GLY. Another than that, the fabrication process that used in this project is by using casting method, but the result of this method is not satisfying to do mechanical test so the effort that can made in this project going smoothly and efficiently is by fabricate bioplastic film in corn and tapioca starch-based TPS using hot press method to ensure the objectives of this project will be achieved. Three testing that have been done are Tensile Test by referring (ASTM D 3039), Hardness Test (ASTMD 2240 D) and Density Test. From all these three tests, found that the composition of 50% corn 50% tapioca starch has the highest tensile value which is 0.15(Mpa). The hardness test value of this composition is slightly lower than pure tapioca with the value 39 compared to 100% tapioca which is 48. While the density value of composition 50% corn and 50% tapioca is the highest of the overall sample composition which the value is 1.42. These findings present this hybrid TPS 50% corn and 50% tapioca starch composition as a best TPS properties for the development of biodegradable packaging materials.
