Welding packaging

Welding is becoming increasingly important in the packaging industry as well. Flexible (e.g. films) or firm (e.g. drinks cartons) packaging types can be joined in this way. Ultrasonic sealing is a special kind of welding. The heat is generated only inside of the materials to be welded. This means that the contents of the packaging are only exposed to a very minimal thermal load. Anvils also focus the energy and ensure slim and tight seals. This saves energy and packaging material, and is therefore more environmentally friendly than other sealing methods.

Ultrasonic sealing is suitable for various applications

Especially suited to welding films

Film packaging in particular benefits from ultrasonic sealing. Here, product residues in the weld seal area are displaced. 100% tight seams are the result. The low thermal load means that the film does not shrink – this is important for a good product appearance.

Ultrasonic sealing technology for packaging technology

Tight packaging with high process speeds, even with contaminated seal areas – that’s what the sealing technology from Herrmann stands for. DAfter the packaging machine has been switched on, the ultrasonic tools are immediately ready for use. Short sealing times and cold tools allow the packaging material and product to be handled with a particularly high level of care. Herrman offers ultrasonic solutions for many different forms of packaging and applications that can be integrated quickly and easily into new and existing packaging systems.

Industry solutions

A variety of possible uses

The ultrasonic welding technology is used for the packaging of products in the FOODMEDICAL or CONSUMER industries. Everywhere where permanently strong, tight and visually flawless packaging is required. With all sealing applications, the ultrasonic generator guarantees reproducible results. With specially developed functions and external sensors, it is possible to safely detect faulty situations and for packaging with damaged seals to be rejected.
