Solution PM 15 containerboard machine to produce low basis weight kraftliner grades

In 2013 Valmet supplied a dryer section rebuild to the machine to improve production efficiency, produce lower basis weight fluting and liner under 100 g/m2, decrease the number of breaks, and cut unplanned shutdown time.
