Abstract
Disclosed is a method for processing cut edges of a blank member, so galled “package sleeve”, made from packaging material, in particular paper/plastics composite material, the cut edges of which are open from above and/or below, by applying a processing medium. In order to develop a simple and cost-effective method, in which the risk of contamination of the packagings and the aseptic region of a filling installation when the package sleeves are filled and closed is reduced, the processing medium contains at least one sterilizing medium and the sterilizing medium remains after being applied to the cut edges and is introduced into the packaging material.
Claims16
A method for processing open cut edges of a plurality of adjacent packaging sleeves comprising paper/plastic composite packaging material and combined in a folded flat state, comprising applying a processing medium from above and/or below onto the open cut edges in the combined folded flat state, wherein the processing medium includes at least one sterilizing medium, the sterilizing medium includes hydrogen peroxide or peracetic acid, and the sterilizing medium remains after being applied to the open cut edges and penetrates into the packaging material via the open cut edges.
