发明名称 METHOD OF PRODUCING A PAPER PRODUCT
摘要 The invention relates to a method of producing a laminate paper product c omprising at least two layers, said method comprising (i) providing an aqueo us suspension comprising cellulosic fibers (ii) adding to the suspension mic rofibrillar polysaccharide in an amount to yield from about 0.05 to about 50 wt% based on the weight of the cellulosic fibers (iii) dewatering the obtai ned suspension and forming a first layer having a density from about 150 to about 500 kg/m3 of said laminate paper product. The invention also relates t o a method comprising (i) providing an aqueous suspension comprising cellulo sic fibers (ii) adding to the suspension microfibrillar polysaccharide in an amount to yield from about 0.05 to about 50 wt% based on the weight of the cellulosic fibers (iii) dewatering the obtained suspension and forming at le ast a first and a second layer of said laminate whereby at least one of said at least first and second layer is formed from an aqueous suspension obtain ed in step (ii) containing microfibrillar polysaccharide; and joining said l ayers in such way that the laminate product obtains a density from about 150 to about 800 kg/m3. The invention also relates to a laminate paper product which can be obtained by the method and the use thereof.
