Customer case:

Stora Enso Varkaus PM3 grade conversion rebuild

May 17, 2016

Growth in traditional retail and e-commerce is increasing global demand for sustainably produced packaging materials. In 2015, Stora Enso’s Varkaus mill in Finland converted their existing paper machine into a board machine to produce linerboard to better meet the market need for renewable packaging. They chose Valmet as their partner for this challenging rebuild.
