Ultrasonic-seminars

Secure your spot now! Go to seminar overview

Sustainable materials with small processing windows are often difficult to work with. The seam result is shrunken and deformed, and is disappointing both visually and haptically.
The use of continuous ultrasonic sealing technology allows us to process even mono-materials to give them a secure seal, and the achieved seam result meets the expectations of the end user. The ZSM also achieves consistent sealing results even at varying speeds. Speeds of up to 35 m/min enable a high production capacity – and at the same time, digital Herrmann generators guarantee your process stability. 

 

 

ZSM

The ZSM module works by sealing the zipper continuously to the film for stand-up pouches and pillow bags.
The zipper is opened by the anvil before sealing and closed again after sealing via the zipper closure on the film.

 

  • for bags and pouches with zippers
  • speeds of up to 35 m/min
  • consistent sealing results, even at varying speeds
  • reduced space requirement
  • hygienic design for easy cleaning
  • easily accessible settings
  • maintenance-free flexure bearing
  •  greater degree of protection thanks to optional IP65/67 protection class

100% process stability
Safe + consistent sealing

The proven ultrasonic sealing technology ensures the controlled introduction of heat to the sealing zone and thus achieves very precise sealing results. Herrmann’s ultrasonic sealing modules therefore guarantee a stable production process – tailored to your specific application.
The digital Herrmann generator ensures that the process data which arises during sealing is recorded without a hitch. This makes reproducibility and controllability really simple, regardless of the time and place.
Problematic adhesion and the resulting need for cleaning are minimized thanks to the cold sealing tools. Down time is also reduced to a minimum.

  • Process safety thanks to a controlled heat introduction
  • Minimal down times as the need for maintenance and non-production times are reduced
  • The look: a perfect sealing result

Easy integration
Compact + flexible

Thanks to its compact size, the ZSM can easily be integrated into existing systems or new machinery. The hygienic design ensures ease of cleaning in the food industry and can also optionally be fitted to meet protection class IP65/67. Thanks to the continuous sealing process, the solution does not rely on bag sizes or number of rails – the production speeds can also be varied quickly and flexibly during the process.


Green packaging
Processing mono-materials safely + efficiently

The process window when sealing mono-materials is smaller than when sealing conventional packaging materials. We understand the challenges relating to sustainable packaging. ZSM is the solution for the safe processing of mono-materials with zippers – without compromising on the visual effect and production capacity! By using the continuous ultrasonic sealing technology, we are able to ensure both.

  • High production capacity
  • Available sealing solution
  • Tried and tested in practice


Like us, Herrmann Ultraschall recognized the significance of sustainable packaging materials early on and worked with us to develop the ZSM, a module for the process-safe ultrasonic welding of zippers. The ZSM is particularly relevant with regard to the processing of thin and sensitive packaging materials. Thanks to this development, we were able to optimize the entire unwinding and folding process in our pouch packaging machines and thus reduce the stress on film and zipper by up to 70%.

Ultrasonic vs. heat sealing

The crucial difference from conventional sealing using thermal jaws is the type of heat introduction. In thermal sealing, the heat comes from outside. The support layer is also warmed and can also be fused.
 In ultrasonic sealing, the heat is generated in a controlled manner via ultrasonic vibrations within the sealing layer. This bonds the sealing layers at a molecular level before any undesired, critical heat conduction is generated through the entire packaging material.
This means that the packaging can be sealed in a way which protects the packaging material itself, as well as the feed material. The risk of shrinkage and warping and possible leakage is minimized.
