Abstract
In the manufacture of aseptic packing containers from weblike laminate material, the material usually is brought into contact with a liquid sterilizing agent which, after a certain treatment period, is removed again. In order to avoid any accumulation of residues of sterilizing agent behind lugs, opening strips or the like a method and an arrangement for finishing an opening arrangement (2) on a packing container (1) are proposed, according to which an external gripping element (3) is placed over the opening region (4) only after the packing container (1) has been filled with the desired contents and has been closed. This is achieved with the help of a sealing unit (9) with a vacuum device (10) and a gas-permeable striplike gripping element (3).
