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.
