Yunda Successfully Signs Contract for Complete Stock Preparation System for Jinlong Holdings’ 6600mm Packaging Paper Project

In February 2025, Zhengzhou Yunda successfully signed an order with Zhejiang Jinlong Renewable Resources Technology Co., Ltd. for the complete stock preparation system of the PM6 project.

The project features a paper machine with a net paper width of 6,600 mm and a design speed of 900 m/min, mainly used for producing high-basis-weight T-paper and testliner paper. Yunda’s supply scope includes:

• Conveying System
• Pulping System
• High-Consistency Cleaning System
• Coarse Screening System
• Fractionating Screening System
• Fine Screening System
• Refining System
• Approach Flow System
• Reject Handling System

The equipment adopts innovative energy-saving technologies. Compared with conventional equipment, the pulping energy consumption will be significantly reduced, while achieving greater stability, reliability, and efficiency.

Following the PM9 300,000 TPA grey board project and the PM10 300,000 TPA grey board project, this order marks the third time Zhengzhou Yunda has empowered Jinlong Holdings’ high-end production line development. It signifies that the strategic cooperation between the two parties has entered a new stage.

This third collaboration not only reflects the industry leader’s high recognition of Yunda’s technical strength, but also represents strong confidence in domestically manufactured papermaking equipment. It further demonstrates that Yunda’s innovative technologies and service capabilities in the global pulp and paper equipment industry have gained wide customer recognition.
