The Paperboard Process - Iggesund

Mechanical Pulp. Refiner mechanical pulp (RMP) is a two-stage process in which the debarked logs are first converted into small flat chips. These chips, with a moisture content of 25–30%, are forced between the rotating metal discs of a refining machine. The heat and water vapour generated soften the lignin so the fibres can be separated.
