Metsä Board Corporation has selected Valmet as the supplier for its new folding boxboard production line at Husum mill, Sweden. The new machine will produce high-quality folding boxboard with an annual capacity of 400,000 tons. The start-up of the machine is scheduled for the beginning of 2016. The value of this size of an order is typically around EUR 60M–70M and it is part of Metsä Board’s EUR 170M investment in the mill.
Valmet’s delivery includes a wet end of the latest OptiConcept M design with headboxes, forming section and press section, as well as a rebuild of the off-machine coater, winder and the roll wrapping line. The wet end area of the machine features the OptiConcept M frame construction without the need for cantilever beams for fabric changes. The fabric changes will be carried out by means of fabric insertion units from Valmet. The 6660 mm-wide (trim) machine, BM 1, will produce folding boxboard (FBB) grades in the basis weight range of 180-350 g/m2 at a design speed of 1000m/min.
