Yunda’s Complete Stock Preparation System for Jinlong’s 6600 mm Packaging Paper Project Enters Commissioning Stage

In April 2026, the complete stock preparation system supplied by Yunda for Zhejiang Jinlong Renewable Resources Technology Co., Ltd.’s 6600 mm paper machine project for specialty packaging paper was successfully installed and has now entered the commissioning stage.

The paper machine has a net paper width of 6,600 mm and a design speed of 900 m/min. It is mainly designed for the production of high-basis-weight T paper and linerboard.

Yunda’s scope of supply includes:

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

For this project, the equipment incorporates innovative energy-saving technologies. Compared with conventional equipment, the new system is designed to significantly reduce energy consumption in stock preparation while providing greater stability, reliability, and efficiency.

This project marks the third collaboration between Yunda and Jinlong, following the two 300,000 t/a grayboard paper projects of PM9 and PM10. The successful cooperation further strengthens the strategic partnership between the two companies and supports Jinlong’s development of high-end paper production lines.

Three successful collaborations reflect Jinlong’s recognition of Yunda’s technical capabilities and project execution expertise, as well as its confidence in high-quality Chinese papermaking equipment.
