As part of this comprehensive cooperation agreement, Köksan will invest a high triple-digit million Chinese Yuan amount in the coming years. The new plant will be in the Yangkou Chemical Industrial Park, Rudong County, Nantong, China. Köksan will be setting up its plant with a production capacity of 2.2-million-tons-per-year green polyester new materials for the packaging industry. The first phase of this project has now been officially launched. Production is scheduled to start in mid-2026.

“We are convinced that this investment will be a major step for our company's future. It is our first investment in China and one of the largest industrial investments by a Turkish company in this area of industry in China. Upon the completion and full operation of this project, Köksan will become one of the global giants in polyester production for the packaging industry”, said Murat Köko?lu, CEO of Köksan. “We are very pleased that Köksan has chosen our innovative CP technology. This is further proof of our capabilities in the field of polymerization technologies”, said Zhong Ming, General Manager of Oerlikon Barmag Huitong Engineering.
