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.

Claims (9)

1. A container for receiving a plurality of flat-folded packaging sleeves, blanks or web material, rolled up into a roll, wherein at least parts of an inside of the container are wetted with a treatment agent, and load carriers wetted with the treatment agent are provided inside the container, and

wherein the treatment agent contains ethanol and a disinfectant,

wherein the treatment agent is configured to be absorbed from the container and the load carriers into open cut edges of the flat-folded packaging sleeves, blanks or web material.

2. The container according to claim 1 , wherein at least an outer surface of the container is sealed at least in a treated region.

3. The container according to claim 1 , wherein cardboard is used as material for the container, and wherein the container comprises a covering box with one or more closable flaps.

4. The container according to claim 1 , wherein plastics is used as material for the container.

5. The container according to claim 4 , further comprising a plastics container and a plastics lid as well as at least one load carrier.

6. The container according to claim 4 , further comprising a shrink film with load carriers.

7. The container according to claim 1 , wherein the disinfectant comprises hydrogen peroxide solution.
