Beschreibung
Zusammenfassung:	Paper product is made starting from aqueous furnish containing fibres and filler. Anionically charged fibril cellulose (B) and cationic strength additive (A) are added to the aqueous furnish (1), and the furnish is made to a paper product by dewatering (D) the furnish. Filler content of the paper product can be increased above 40 wt-%. Paperituote valmistetaan lähtien vesipohjaisesta massalietteestä, joka sisältää kuituja ja täyteainetta. Vesipohjaiseen massalietteeseen (1) lisätään anionisesti varautunutta fibrilliselluloosaa (B) ja kationista lujuutta parantavaa lisäainetta (A), ja massaliete valmistetaan paperituotteeksi poistamalla (D) massatuotteesta vettä. Paperituotteen täyteainepitoisuus voidaan nostaa yli 40 p-%:iin.
