The world’s largest cartonboard production line, Ningbo Asia Pulp & Paper’s (APP) PM 6 in Xiaogang, Ningbo City in Zhejiang Province, China, has reached a new milestone in its operation. On August 20, 2010, PM 6 produced 300 g/m2 art board at the amazing speed of 1,020 m/min for 17 hours without any breaks.
"Surpassing the 1,000 m/min limit is another proof of this line’s capability, and the result of the combined efforts of both Ningbo APP and Metso to maintain the number one position," says Chen Hsing Liang, COO of APP industrial papers business units.
The 410-m-long Ningbo Xiaogang PM 6, which was started up in November 2004, today produces high-quality graphic art board and folding box board in the basis weight range of 250 to 450 g/m2. It can also produce white lined chipboard (WLC). The line has a trim width of 8.1 m and a design speed of 900 m/min. Supplied by Metso, the line consists of a complete eight-line stock preparation system for both virgin and recycled fiber, and a complete five-ply board machine including a five-station on-line coater.
