Liansheng Paper PM5 containerboard machine in China
Valmet's delivery to Liansheng Paper's Longhai site in Fujian province in China included a complete boardmaking line from headbox to reel with air systems, a size supply system, a quality control system and a winder. The 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 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 Valmet also in the future.”
