Valmet has confirmed it has been selected by Sun Paper to deliver a complete board making line, including automation and lifecycle support, for its mill in Nanning, China. The investment aims to increase containerboard capacity while ensuring reliable, energy- and resource-efficient operation. The start-up is scheduled for autumn 2027.
“The high-capacity machine concept and the selected advanced technologies support our targets for energy-efficient and stable production,” says Ying Guangdong, Vice General Manager and Chief Engineer, Sun Paper. “We expect these solutions to deliver strong performance while reducing energy consumption and ensuring our capacity goals are achieved. We value the long-standing relationship we have built with Valmet and look forward to continuing our cooperation with this new project.”
“The machine, including the Sleeve roll technology and compact dryer geometry, provides an excellent foundation for optimised and energy-efficient containerboard production. We are pleased to continue supporting Sun Paper with this board machine project and lifecycle services,” says Pekka Tolvanen, Sales Manager, Packaging and Paper Business Area, Valmet.
The delivery includes a complete board machine from headboxes to winders, incorporating several technologies designed to support high-capacity production of kraft and testliner while improving energy efficiency and runnability.
The forming section will feature Valmet’s Sleeve roll technology, which uses forming fabric compression to enable efficient dewatering while supporting quality targets and reduced energy consumption. The dryer section will include a compact geometry design to improve drying efficiency and machine performance, while two winders will support reliability and roll quality.
The order also includes lifecycle services to support stable production and long-term machine performance, including spare parts, digital services, and paper machine clothing. Improvements to other existing machinery at the customer’s site are also included.
A comprehensive automation package will help improve production efficiency and machine safety while providing a foundation for the mill’s transition towards increased levels of autonomy.
