Liansheng Paper Industry Starts up New Containerboard Line at Longhai Site in China

Liansheng Paper Industry (Longhai) Co., Zhangzhou, China, has started up its new Metso (Finland)-supplied containerboard production line, PM 5, at the company's Longhai site in Fujian province in China. The new 7.25-m-wide PM 5 has an annual production capacity of approximately 350,000 metric tons of recycled testliner in the basis weight range of 100 to 140 gsm. The design speed is 1,200 m/min.

Metso's delivery included a complete boardmaking line from headbox to reel with air systems, a size supply system, a quality control system, and a winder.

The PM 5 testliner production line features a novel two-layer forming process with only one hybrid forming unit equipped with the new OptiFlo layering headbox. With this innovative technology, a two-layer web can be produced with only one headbox, providing excellent profiles due to a unique dilution system and good formation due to new type of hydraulics.

"The PM 5 startup was successful with a stable operating process. The desired targets were achieved. I hope that we can continue a very good cooperation with Metso also in the future," said Rongjun Xue, project manager of Liansheng Paper.

Liansheng Paper Industry is a subsidiary of Fujian Liansheng Paper Co., Ltd. A third Metso-supplied production line for Fujian Liansheng, PM 6 is to start up at the Longhai site this month. The PM 6 boardmaking line will produce recycled fluting grades. It has the same width and design speed as PM 5.
