  • Publication number: 20240426060
    Abstract: The present invention relates to a method for manufacturing a multiply paperboard, comprising forming a first web on a first wire, a second web on a second wire and a third web on a third wire. The second web comprises a delamination web layer formed from a second pulp suspension comprising 5-80 weight-% refined CTMP and/or CMP. A first coating layer comprising 0.2-20 g/m2 starch is applied to a non-wire side of the first web by curtain application. A second coating layer comprising 0.2-20 g/m2 starch is applied to a non-wire side of the second web or the third web by curtain application. A multilayer web is formed by joining the third web with the second web via the second bonding layer and by joining the second web and the first web via the first bonding layer. The multilayer web is further dewatered and optionally dried to form the multiply paperboard. The invention relates also to a multiply paperboard.
