Abstract: A method for the production of highly refined or microfibrillated cellulose (MFC), comprising the steps of treating cellulosic fibres to remove at least a major part of the primary wall of the fibres, drying the treated fibres, rewetting the treated fibres, and disintegrating the wetted fibres by mechanical means to obtain the final product. Dried cellulosic pulp is produced as an intermediate product of the method, having an average fibre length of at least 0.4 mm, while less than 50% of the primary wall material of natural untreated fibres is left in the intermediate product. Instead of transporting large amounts of dilute MFC dispersion the invention enables transport of the dry intermediate product to the MFC end user, who would complete the process by turning the intermediate product to final MFC by use of standard disintegrating devices.

Abstract: The invention relates to a packaging board comprising a fibrous base and one or more polymer coating layers on one or both sides of the fibrous base. According to the invention the fibrous base contains the combination of an alkyl ketene dimer size, stearic acid anhydride, a wet-strength size and an aluminium compound, which give the board resistance to aggressive liquids as well as thermal treatment, particularly an improved resistance to raw edge penetration in such circumstances. The invention further relates to containers and packages made of the board, for instance disposable drinking cups, dairy product cartons and auto-clave packages, as well as use of the board for such purposes.
