On October 28, 2012, Liansheng Paper Industry (Longhai) Co., Ltd started up their new Metso-supplied containerboard production line, PM 5, at their Longhai site in Fujian province in China.

"The PM 5 start-up 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,” says Rongjun Xue, Project Manager of Liansheng Paper.

The new 7.25-m-wide PM 5 has an annual production capacity of approximately 350,000 tonnes of recycled testliner in the basis weight range of 100 to 140 g/m2. 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.

Liansheng Paper Industry (Longhai) Co., Ltd. is a subsidiary of Fujian Liansheng Paper Co., Ltd. The company was founded in 1999 and is based in Zhangzhou, China. A third Metso-supplied production line for Fujian Liansheng, PM 6, is to start up at the Longhai site in December this year. The PM 6 boardmaking line will produce recycled fluting grades and it has the same width and design speed as the PM 5.
