Liansheng Paper Industry (Longhai) Co., Ltd started up their new Metso-supplied containerboard productionline, 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 productionline 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.
