SONOTRONIC GmbH
Roll seam module with cantilevered sonotrode
Ultrasonic sealing without heat loading of the filling material
An ever expanding application for the continuous ultrasonic sealing method from SONOTRONIC lies in packaging technology.
Applications
Here ultrasonic roll seam technology is applied mainly in horizontal and vertical tubular bag machines. Bags with four sealed edges can also be produced by ultrasonic roll seam sealing.
New possibilities in the choice of film
In addition, unlike other thermal processes, ultrasonic technology makes it possible to use monofilms, since no heat-insensitive outer layer needs to be laminated onto the film. Furthermore, even very thin polymer films (15 μm) can be sealed in high quality with the continuous ultrasonic process, which has not been possible satisfactorily with other thermal sealing systems so far.
Economic process Both the roll seam sonotrode and the anvil are driven in this process so that there is neither slip nor wave formation in the film. No relative movement is generated between the sealing wheel and film by the double drive either.
