Food quality is a basic human need. Current complaints decline in the quality of food as a result of contamination of insects carrying germs. One of the efforts to prevent the food packaged in containers. Packaging are widely used and appreciated by the public is styrofoam. Styrofoam is a polystyrene that aren’t biodegradable and can have a negative impact on health due to migration of chemicals in packaged foods. Moreover styrofoam doesn’t inhibit the entry of insects, especially ants. Presence of ants on the food can lower consumer acceptance of the food. To overcome these problems required modification in order to produce styrofoam packaging that can be degraded by natural and safe to use as food containers and has anti insects especially ants. Starch is a polymer that can be described as a mixture of biological allowing their use produces styrofoam packaging that is biodegradable and safe for health. Starch used is waste corn cobs. To give effect to anti-ant, given substitution peppermint extract of mint leaves (Mentha piperita) containing the active ingredient menthol and menthone flavonoids. In order to obtain packing with adjustable power, detainees tired, corrosion resistant, and has a power type is high then applied to the manufacture of nanocomposite technology. Manufacture of nanocomposite materials can be done with a simple approach to the complex and simple mixing method. Best results are obtained by the addition of methanol extract of leaves of mint 0,25 % concentration. In vivo toxicity tests using wistar mice showed no indication of toxicity or side effects. Biodegradation test using Aspergillus niger shows the effect of biodegradation in a few months. Faster than commercial styrofoam can be degraded within a period of hundreds of years.
