Abstract

A method for producing a packaging material comprises providing a core material layer of fibre-based material having an inner side and an outer side, embossing the core material layer for forming embossed features having an initial height, the embossed features protruding from the outer side of the core material layer to later form a tactile pattern on a side of the package to be formed by the packaging material, and laminating at least one layer to the inner side of the embossed core material layer such that the height of the embossed features is temporarily reduced to a minimum height.
