Abstract: The invention relates to a paper or paperboard comprised of one or more plies, wherein at least one ply comprises a mixture of cellulose fibers and a strength enhancement agent selected from the group consisting of microfibrillated cellulose (MFC) and highly refined cellulose, and wherein said paper or paperboard has been subjected to grafting with a fatty acid halide such that ester bonds are formed between carbonyl groups of the fatty acid halide and hydroxyl groups of the cellulose fibers and the strength enhancement agent. The invention also relates to a method for manufacturing paper or paperboard.

Abstract: Method for hydrophobing a cellulose substrate (1), which comprising a first side and a second side, which faces away from the first side. The method comprising the steps of drying a cellulose substrate (1) to a dry content above 80%, preferably above 85%, adding a vaporized fatty acid halide, to the first side of the cellulose substrate, and, at the same time perform vacuum sucking at the second side of the cellulose substrate, such that, the vaporized fatty acid penetrates the cellulose substrate (1) in a predetermined direction through the substrate.
