The invention relates to a method for manufacturing SCK paper having a basis weight of less than 50 g/m, wherein an optimal combination of BSKP, BHKP and BCTMP is used to adjust the properties of the fiber furnish. In SCK papers with very low basis weight the formation of the paper web upon paper manufacturing may be controlled by means of the fiber furnish optimization, which can be used to produce exceptionally thin SCK paper without downgauging and without adverse effects to other paper properties, which would prevent the use of the SCK paper as substrate layer in a release liner. Thus SCK paper with a moderate share of BCTMP in the fiber furnish may be produced, that has quality characteristics of the paper sufficient for use as a substrate layer of an industrial release liner.
