Japan has developed a new biodegradable packaging material that can withstand water

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 plastics that use corn gluten meal and bean curd residue as raw materials. However, the water resistance of the manufactured packaging material is not enough to make this newly developed water resistant product. Biodegradable materials cannot 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 discovered that in order to improve water resistance, it is effective to use corn seed gliadin. In order to improve water resistance, the use of corn seed prolamins is effective. 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 the sheet, and successfully inject the sheet. For the film.
