Title: Innovations of Toshiyuki Shimizu
Introduction
Toshiyuki Shimizu is a notable inventor based in Ohtsu, Japan. He has made significant contributions to the field of materials science, particularly in the development of polylactic acid resin compositions. With a total of 7 patents to his name, Shimizu's work has implications for both packaging and molding materials.
Latest Patents
One of Shimizu's latest patents is a polylactic acid resin composition and film. This innovative composition serves as a useful molding and packaging material. It comprises a resin composition (l) made of poly-L-lactic acid with an L-isomer content of 90-100 mol % as the main component, and a resin composition (d) consisting of poly-D-lactic acid with a D-isomer content of 90-100 mol %. These resin compositions are alternately stacked, with each layer having a thickness of 0.01-2.5 μm. The resulting polylactic acid resin composition exhibits specific thermal properties, allowing it to be used at high temperatures even after high-temperature melt molding. It also provides molded polylactic acid articles that are suitable for various processing methods, including printing, and boasts excellent transparency. Additionally, Shimizu has developed a stretched polylactic acid resin film, which is obtained by heating the resin composition to 280°C or higher, cooling it, forming it into a film, and then stretching it in at least one direction. This film is designed for high-temperature applications and offers excellent processing suitability and transparency.
