Japan developed a water-resistant protein film

This packaging film was successfully developed by the Food Research Institute of Japan's Ministry of Agriculture, Forestry and Fisheries. It is suitable for covering expanded starch foods. The film is a new type of packaging material that can replace Styrofoam, and its strength is comparable to that of a synthetic food packaging film. Because its main ingredient is corn, it has biodegradability and will not pollute the environment.
