Plastic packaging has dominated the waste and the number is increasing every year. Candy plastic packaging waste is most often considered trivial because of its small size so it is usually disposed of carelessly. Every year the candy packaging waste contributes 0.3 billion. Due to its nonbiodegradable, it causes environmental pollution. Edible filmpackaging is an alternative to reduce the impact of candy packaging waste pollution.The purpose of this study was to obtain the optimum formula of edible film between based maize starch, carrageenan and rice bran as a hard candy packaging with the Response Surface Methodology (RSM) Central Surface Composite Design using the Design Expert 10.0.7. The prediction data obtained is then verified and tested by t-test at a 5% reliance interval.The optimum formulation of RSM results is 3,4% of maize starch, 1,1% of carrageenan and 0,38% of rice bran with predicted response of water content of 14,51%, WVTR 61,06 g/m2/hour, viscosity of 258,8 cP, tensile strength of 107,9 kgf/cm2, elongation of 19,41%, and modulus of response young 586,28 kgf/cm2. The verification had a moisture content of 14,37%, WVTR 63,34 g/m2/hour, viscosity of 244,9 cP, tensile strength of 96,9 kgf/cm2, elongation of 20,96%, and young modulus of 462,49 kgf/cm2
