Wetlaid web, selected from the group consisting of wet-laid non-woven fabrics and paper, comprising a cellulosic fibre material in the form of viscose fibre at an amount of at least 5% w/w, characterized in that the wetlaid web comprises microfibrillated cellulose at an amount of 0.5% w/w to 5% w/w, wherein the microfibrillated cellulose has a particle size distribution (x.sub.10) of 5 μm to 30 μm, and a wet-strength agent.

A method of making a paper product can comprise making one or more sheets at least by, for each of the sheet(s), forming a web from one or more furnishes that comprise fibers dispersed in water. The fibers of the furnish(es) can comprise a plurality of first fibers that are hardwood fibers and a plurality of second fibers that include softwood fibers and surface enhanced pulp fibers (SEPF), the SEPF having a length weighted average fiber length of at least 0.20 mm. The method can comprise at least partially dewatering the web to form the sheet. The sheet(s) can be laminated and/or embossed such that a total dry tensile strength of the paper product is less than or equal to 90% of the sum of the total dry tensile strength(s) of the sheet(s).
