Jin Shangyi Co. Ltd. is the composite structure and its application of professional research, promotion company. Company research institute under the concave convex structure, pilot plant, promotion and marketing center. In recent years, the company has made great achievements in scientific research. Concave convex structure of composite board are invented by the study of concave convex structure, the first use of extension type material, composite of two to finalize the design, materials, create a new structure. Domestic and foreign experts, the media, the authority first reported, successively in the "China Packaging newspaper", "Chinese and foreign", "packaging and printing packaging industry" magazine wrote many articles, the concave convex structure and corrugated, honeycomb structure mentioned in the same breath, points out that following the nineteenth Century British invented corrugated, honeycomb in twentieth Century after an American invention, twenty-first Century at the beginning of the Chinese invented the bump, known as the great invention, is a great contribution to the global corrugated box. The famous packaging critics, China Packaging newspaper outstanding reporter, Jiangsu Packaging Technology Association first Secretary General Mr. Huang Shanxiang in his "packaging by the theory of" quoted foreign scientists strongly "hole theory" theoretically, the concave convex structure is scientific and practical, the simple act of concave convex structure invention than American civil rights movement pioneer Rosa Parkes rejected as a white man and suffered arrest and lead the nation's civil rights movement to change the history of the United States: "in the concave convex structure invented in China, is also a very simple act, has the potential to change the world packaging structure history." Pilot plant research around the concave convex structure of the production equipment, process equipment has become mature. The concave convex structure of large area popularization of technology and provide a reliable guarantee, will be a new technology and innovation to our country and the world packaging, construction, iron and steel, ships, aircraft manufacturing productivity.
