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.

Abstract: Packaging containers of single-use disposable type which are manufactured from flexible paper/plastic laminate normally display sealing fins (3) which extend over one or more of the walls (2) of the packaging container (1). In parallelepipedic packaging containers, triangular corner flaps (4) moreover occur over which extend the sealing fins (3). The corner flaps are folded down and secured on the final formation of the packaging container against its side wall. This however entails that the material with many times thickness must be double-folded, which entails deformations and stretching which damages the packaging material so that this no longer remains completely liquid-tight and gas-tight. According to the invention, the above-outlined drawbacks may be obviated in that the fibre layer included in the material is heated to a temperature of between 80 and 250° C.
