Amongst other things, Packaging industry is challenged by increasing recycling rates and the usage of monomaterial-like packaging foils, due to increasing social and legal requirements regarding to ecologically beneficial packaging. This will result to the abandonment of the conventional separation into carrier and sealing layer in packaging films and is accompanied by a decreasing efficiency in packaging processes based on heat-sealing technology.
Therefore, other techniques are receiving more attention, like ultrasonic sealing. Their market penetration is still low, because of higher process complexity and a generally higher sensibility against process variation. In addition to the advantage of using cold sealing tools, this technique benefits from an electronically process control, which makes a variety of process data available. Currently, these data are not being used sufficiently, but automatic process evaluation can be done by us-ing current methods, like machine-learning algorithm.
