Abstract
A method of producing overpressure valves for packaging containers supplied in a roll, transported in this form to a packaging machine, separated at the machine and attached to packaging containers by means of an adhesive coated surface. For this purpose the overpressure valves have a layer of emulsion bonding on their underside. To prevent individual layers of the roll from sticking together, the overpressure valves have an adhesive-repelling layer on their top side. The overpressure valves are connected to one another in one piece and in a row, and are separated consecutively in a packaging machine.
