Abstract: The invention relates to a method of making a paper or paper board, in which method cut pulp is prepared by cutting basic cellulosic fiber pulp at the consistency of at least 25 % so that the average fiber length of the basic pulp is decreased by more than 25 % and the SR number of the cut pulp is at most 20 % higher than that of the basic pulp, and the cut pulp is used as a raw material in the preparation of a stock.

Abstract: The invention relates to a method for manufacturing nanostructured paper or board and a novel paper or board. The method comprises providing a liquid suspension of nanocellulose-containing material, forming a web from the suspension and drying the web in order to form paper or board. According to the invention, the water content of the suspension at the time of beginning of the drying is 50 % or less by weight of liquids so as to form a paper or board having an average pore size between 200 and 400 nm. By means of the invention, very opaque paper, for example for printing applications, can be manufactured with low energy consumption.
