Abstract: A method for treating open cut edges of a packaging sleeve, blank or web material of a packaging material rolled up into a roll, in particular a composite cardboard/plastics material, by applying or introducing a disinfectant-containing treatment agent to or into the outer region of the cut edges. To provide a particularly resource-efficient composite packaging and a production method required for this purpose, it is proposed that at least some of the treatment agent is not applied directly to the cut edges, but that a load carrier is loaded, which load carrier absorbs the treatment agent so that an actively sterilising atmosphere which is created then acts on the open cut edges of the packaging sleeve, blank or web material and performs the desired sterilisation. The invention also relates to a packaging material, to a combipack produced therefrom and to a container for receiving the packaging material.
