Valmet's Innovative Board Making Line to Enhance Sun Paper's Sustainability in China

Valmet, a leader in technology solutions for various industries, has announced a significant project in collaboration with Sun Paper. This initiative involves the delivery of a comprehensive board making line along with lifecycle support to Sun Paper’s mill in Nanning, China. This strategic partnership aims to bolster Sun Paper's production capacity and promote energy-efficient and resource-conscious operations from the start of its operations.

The board making line is expected to commence its operations in the fall of 2027, with enhancements including advanced automation and lifecycle services to ensure long-term efficiency and performance. Ying Guangdong, Vice General Manager and Chief Engineer of Sun Paper, emphasized the importance of this project, stating that the high-capacity machine concept, complemented by selected advanced technologies, will significantly contribute to energy-efficient and stable production.

The technological innovations in this board making line include the transformative Sleeve roll technology. This advancement allows for highly effective dewatering in the forming area through strategic forming fabric compression, leading to reduced energy consumption and superior product quality. The driver of growth for this initiative is the targeted increase in containerboard production capacity, which also focuses on maintaining a reliable operational foundation.

In addition to the forming technology, the dryer section of the board machine presents groundbreaking compact geometry that ensures the efficient drying of paper with superior performance metrics. This setup not only optimizes production but also enhances the overall runnability of the machine. The integration of two winders in this system further guarantees high-capacity output and excellent roll quality.

Moreover, the delivery package encompasses various lifecycle services. These services not only include essential spare parts but also essential digital services and specialized paper machine clothing, aimed at creating a solid foundation for the mill's productivity and ensuring consistent lifecycle performance of the board machine.

Valmet’s commitment to continued support for Sun Paper’s projects underlines its dedication to fostering functional sustainability in the industry. The extensive automation solutions included in this project are designed to enhance the efficiency and safety of production while positioning Sun Paper for a transition toward higher levels of operational autonomy.

Valmet's rich experience over more than two centuries in process technology has endowed it with the expertise needed to deliver exceptional service and solutions worldwide. With the value of the order undisclosed, it remains a significant addition to Valmet's portfolio and is counted among the orders received for the second quarter of 2026.
