A pulp mixture comprising a first pulp and a second pulp， the first pulp consisting of a chemical softwood pulp which has been subjected to high consistency refining followed by low consistency refining， the second pulp consisting of a bulk increasing pulp selected from the group consisting of a chemi-thermomechanical pulp (CTMP)， a thermomechanical pulp (TMP) and a chemical softwood pulp which has been subjected to low consistency refining without preceding high consistency refining， and wherein: in the case the second pulp is a CTMP or a TMP， the first pulp is present in an amount of 20-90 %， such as 25-90 %， such as 50-90 % by dry weight of the total dry weight of the first pulp and the second pulp; in the case the second pulp is a chemical softwood pulp which has been subjected to a low consistency refining without preceding high consistency refining， the first pulp is present in an amount of 5-90 % by dry weight of the total dry weight of the first pulp and the second pulp.
