Enstra Paper, member of the Corruseal Group and one of the largest producers of recycled containerboard grades in South Africa, has engaged Voith to rebuild its PM 6 for packaging paper in Springs, close to Johannesburg, in South Africa. Voith will supply a new BlueLine OCC stock preparation line to improve efficiency, runability and paper quality. The leading full-line supplier will also undertake substantial rebuild measures on the existing paper machine that was converted from newsprint to packaging papers in 2015.
