Metso to supply folding boxboard machine rebuild for Cartones Ponderosa in Mexico

HELSINKI, May 17, 2011 (Press Release) - Metso will rebuild the folding boxboard machine at the San Juan del Río mill of Cartones Ponderosa, S.A. de C.V. in Mexico. The start-up of the rebuilt PM 1 machine is scheduled for the second quarter of 2012. The value of the order will not be disclosed.

Metso's delivery will include rebuilds of the coating and drying sections.
