Abstract
The present invention relates to a packaging machine having an ultrasonic device (), the ultrasonic device () comprising: an ultrasonic generator () which generates electric vibrations; an ultrasonic converter () which converts the generated electric vibrations into mechanical vibrations of the same frequency; a transformation intermediate piece () which transfers the mechanical vibrations to a sonotrode (); the sonotrode () comprising a sound-radiating end surface () at which it reflects the mechanical vibrations, so that a standing wave to be passed into a packaging foil () is formed, and the sound-radiating end surface () being disposed in a vacuum and/or in a modified atmosphere.
