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.

First claim

The invention claimed is:

1. A method for treating open cut edges of a packaging sleeve, blank or rolled web material of a packaging material, comprising:
applying a treatment agent containing a disinfectant to an outer region of the cut edges, wherein at least some of the treatment agent is not applied directly to the cut edges;
loading a load carrier, wherein the load carrier absorbs the treatment agent, so that an actively sterilising atmosphere is created;
wherein the actively sterilising atmosphere acts on the open cut edges of the packaging sleeve, blank or web material and performs a sterilisation.

2. The method according to claim 1 , further comprising indirectly transferring at least some of the treatment agent by evaporation and subsequent absorption in the open cut edges.

3. The method according to claim 1 , further comprising separating the actively sterilising atmosphere from surroundings by a container.

4. The method according to claim 3 , further comprising wetting at least parts of the container, in particular parts of an inside, with the treatment agent, and using the parts as the load carrier.

5. The method according to claim 3 , further comprising inserting carrier elements into the container, and using the carrier element as the load carrier.

6. The method according to claim 3 , further comprising loading the load carrier with the treatment agent before the container is closed.

7. The method according to claim 3 , further comprising loading the load carrier with the treatment agent after the container is closed.

8. The method according to claim 1 , further comprising using a treatment agent which contains a dye, and discoloring treated regions.
