Södra black is made from juvenile spruce and pine trees which are removed in thinning operations. The pulp fibres are thin and flexible, so they form strong bonds in the paper. Södra black produces a high-density paper with a smooth and even surface with strong tensile, burst and Z-strength properties. This pulp is also easy to process, which improves the energy efficiency of paper production.
