Water-resistant biodegradable packaging material development process

Recently, three research teams, including the Japan Showa Industrial Co., Ltd. and the Food Research Institute, focused on the injection molding method widely used in the manufacture of plastic products, and eventually developed wastes such as adding corn gluten meal, bean curd refuse, etc. Raw materials, methods for making biodegradable packaging materials with excellent water resistance.

The company used the joint research of the Japan Food Research Institute and the Japan Steel Institute to develop the additive-free corn gluten meal and soybean curd residue as raw materials. The degree of freedom in producing water-resistant organisms is low, and this newly-developed water-resistant biodegradability has been developed. It is difficult for materials to be fully utilized and promoted. The company's Food Research Institute conducted a new study on a method for producing a biodegradable film with good water resistance, and finally found that in order to improve water resistance, it is effective to use corn seed protein prolamin. In order to reduce the production cost, it is possible to use the bean curd of cereal and gluten meal containing phytolysin, the stems and leaves of crops, and the mushroom culture medium as the main raw materials, use the extrusion method to make tablets, and successfully injection-mold the tablets. For the film.
