NANNING, China — Valmet has secured an order from Sun Paper to supply a complete containerboard production line, automation systems and lifecycle services for the company’s mill in Nanning, Guangxi, supporting plans to expand containerboard capacity with improved energy and resource efficiency.

The new board machine is scheduled to start up in fall 2027 and will produce kraftliner and testliner grades for the growing packaging market.

Full Production Line to Boost Containerboard Capacity

The delivery includes a complete board making line, from headboxes to winders, along with advanced automation, digital services, spare parts and paper machine clothing.

According to Valmet, the project is designed to help Sun Paper achieve reliable, high-capacity production while reducing energy consumption and improving operational efficiency.

The order was recorded in Valmet’s second-quarter 2026 orders received, although the contract value was not disclosed.

Advanced Technologies Target Energy Efficiency

The new production line incorporates several of Valmet’s latest papermaking technologies, including its Sleeve Roll forming technology, which improves dewatering by optimizing forming fabric compression.

The company said the system enables more efficient energy use while maintaining high board quality.

Other key features include:

• Compact dryer section geometry for efficient drying
• Advanced runnability systems
• Two high-capacity winders for improved roll quality
• Integrated automation and digital monitoring solutions

The project also includes upgrades to selected existing equipment at the mill.

Automation Supports Future Smart Manufacturing

Valmet’s automation package is intended to improve production efficiency, machine safety and operational stability while supporting Sun Paper’s long-term transition toward more autonomous manufacturing.

Lifecycle services, including digital support and maintenance solutions, will help maintain machine performance throughout its operating life.

Supporting Integrated Forest-Pulp-Paper Production

Nanning Sun Paper is a wholly owned subsidiary of Shandong Sun Paper and operates an integrated forest-pulp-paper production model focused on intelligent manufacturing and low-carbon operations.

Based in Guangxi, the mill supplies customers across Southwest China while also exporting paper products to ASEAN markets.

Sun Paper said the investment will strengthen its containerboard production capacity while supporting more energy-efficient and reliable manufacturing as demand for packaging papers continues to grow.
