International technology Group ANDRITZ has successfully started up the rebuilt PM10 at Laakirchen paper mill for the Heinzel Group, Austria. The machine that originally produced SC paper was converted to a fluting and testliner machine producing basis weights ranging from 70 to 140 g/m² based on recycled fibers. With a design speed of 1,600 m/min and a working width of 7,500 mm, it is now one of the world’s most productive paper machines for fluting and testliners.
