Method for producing a multilayer machine glazed paper comprising highly refined cellulose fibers and a multilayer machine glazed paper produced

A method for manufacturing a multilayer machine glazed paper comprising highly refined cellulose fibers, the method comprising the steps of:

• a) forming a first wet web by applying at least one first pulp suspension comprising highly refined cellulose fibers having a Schopper-Riegler (SR) value in the range of 65-99 as determined by standard ISO 5267-1 on a first wire;
• b) partially dewatering the first wet web to obtain a first partially dewatered web;
• c) forming a second wet web by applying at least one second pulp suspension comprising highly refined cellulose fibers having a Schopper-Riegler (SR) value in the range of 65-99 as determined by standard ISO 5267-1 on a second wire;
• d) partially dewatering the second wet web to obtain a second partially dewatered web;
• e) joining the first and second partially dewatered webs to obtain a multilayer web;
• and,
• f) glazing the multilayer web in at least one glazing unit to obtain a multilayer machine glazed paper comprising highly refined cellulose fibers, wherein the at least one glazing unit is a Yankee cylinder,
• wherein the first pulp suspension, the second pulp suspension, or both comprises between 50-99.9 wt % of unrefined or slightly refined cellulose fibers having a Schopper-Riegler (SR) value below 30, as determined by standard ISO 5267-1, based on a total dry weight of the respective pulp suspension, and
• wherein the first pulp suspension and, the second pulp suspension comprise 0.1-40 wt % highly refined cellulose fibers based on a total dry weight of the respective pulp suspension,
• wherein the first pulp suspension and the second pulp suspension have different compositions such that one of the first pulp suspension and the second pulp suspension comprises a lower amount of the highly refined cellulose fibers and a higher amount of the unrefined or slightly refined cellulose fibers than the other of the first pulp suspension and the second pulp suspension, and
• wherein the multilayer web is arranged such that a surface formed from the one pulp suspension comprising the lower amount of the highly refined cellulose fibers is directly contacted with the Yankee cylinder during glazing.
