A method for producing at least one, in particular external, aroma protection valve for a packaging container, having a basic element and having a valve membrane which is connected at least in sections to the basic element in a joining process by an energy input, the basic element and the valve membrane being connected to each other without an adhesive in the joining process. The basic element and the valve membrane (14a) are connected at least in sections in the joining process by ultrasonic welding, wherein the basic element and the valve membrane are connected to each other in the joining process on a base element, in particular a film web, which is provided for handling and/or stabilizing the basic element and/or the valve membrane during the joining process.
A method for producing at least one aroma protection valve (10a) for a packaging container, having a basic element (12a) and having a valve membrane (14a) which is connected at least in sections to the basic element (12a) in a joining process (100a) by an energy input, the basic element (12a) and the valve membrane (14a) being connected to each other without an adhesive in the joining process (100a), wherein the basic element (12a) and the valve membrane (14a) are connected at least in sections in the joining process (100a) by ultrasonic welding (26a), wherein the basic element (12a) and the valve membrane (14a) are connected to each other in the joining process (100a) on a base element (50a) which is provided for handling and/or stabilizing the basic element (12a) and/or the valve membrane (14a) during the joining process (100a).
