Abstract (en)
[origin: WO2014029917A1] Printing paper product is made by multilayer technique starting from aqueous furnish comprising fibres and strength additive. In the aqueous furnish comprising fibres and strength additive, nanofibrillar cellulose and strength additive is fed in a middle layer to form a multilayer printing paper, and the paper product is made by dewatering of the furnish whereby the nanofibrillar cellulose and the strength additive migrate to the surface layers to increase the internal bond strength of the printing paper.
