A coated food cardboard that is comprised of a cardboard layer and a coating layer at least on one side of it, and a method of producing it. Between the coating layer and the cardboard surface is formed by dispersion coating a barrier layer that is comprised of binder and slate-like pigments. The layer is formed of a dispersion that is prepared by dispersing slate-like pigment in water and mixing this with a non-hydrophobic binder. The cardboard has excellent barrier properties and it can be used, for example, in such a pigment coated cardboard, in particular fresh fibre cardboard that has good properties of mineral oil migration and fat penetration prevention. |
