Method for manufacturing a cellulose-based laminate comprising a mineral-based layer

A method for manufacturing a cellulose-based laminate comprising a mineral-based layer in a paper-making machine, the method comprising:

• a) forming a first web layer by applying a first suspension comprising at least 50%, by dry weight, of a cellulose-based fibrous material having a Schopper-Riegler (SR) value in a range of 18-50 on a first wire, and partially dewatering the first web layer on the first wire to form a partially dewatered first web layer;
• b) forming a second web layer by applying a second suspension comprising 60-95%, by dry weight, of a particulate mineral, and
• 5-40%, by dry weight, of a binder, wherein said binder is a highly refined cellulose (HRC) having an SR value in a range of 75-100,
• on a second wire, and partially dewatering the second web layer on the second wire to form a partially dewatered second web layer,
• wherein the second suspension has a dry solids content of at least 0.5 wt % and the second suspension is applied directly on the second wire using a curtain applicator;
• c) laminating the partially dewatered second web layer and the partially dewatered first web layer to obtain a laminate web;
• and
• d) dewatering, and optionally drying, the laminate web to obtain a cellulose-based laminate comprising a mineral-based layer.
