Ultrasonic sealing technology has become an established and economic alternative to heat sealing. For packaging with thermoplastic sealing layers, – such as capsules, pouches, drink cartons, cups and trays – the efficient sealing process offers several advantages for the packaging industry: above all, high cycle rates and tight seals despite potential product residues in the seal area.

Successful ultrasonic solutions

Our solution for maximum efficiency

Sealing through contamination

With ultrasonic sealing, packages are sealed 100 % tightly even if there are residues of the contents in the seam area.
In the sealing process, the vibrations of the ultrasonics displace these residues reliably from the sealing zone – regardless of whether the contents are solid, moist or liquid.
This significantly reduces rejects and at the same time extends the shelf life of the products.

New process: Sealing uncoated paper with ultrasonics

Ultrasonic sealing of uncoated paper is a joining process that is as innovative as it is environmentally friendly, enabling packaging companies to save significant amounts of energy and resources. Patent holder Syntegon Technology GmbH recently handed over exclusive rights to the process to Herrmann Ultraschall. The company wants to move the process to market maturity and establish it in the packaging industry.

Sustainable and efficient sealing with the new TSM

Save energy and material permanently: with the TSM Top Seal Module Herrmann Ultraschall offers a simple solution for sealing packaging materials more efficiently and reliably. Thanks to the new solution for sealing the hermetic and cosmetic seal at the same time, companies can also reduce the size of their packaging machines.

News

Three in one go

It’s a space-saving and sustainable solution for sealing hermetic and cosmetic seals on stand-up pouches: with the COS upgrade for the top seal module TSM from Herrmann Ultraschall, manufacturers of packaging machines will be able to perform several work steps in just one sealing station.

News

Save 75% plastics

Together with the packaging service provider Verdesoft, Herrmann Ultraschall has developed a cup and a tube that can be closed by ultrasonics. The packaging concepts have a comparable product protection as conventional plastic packaging and save up to 75% plastic.

Ultrasonic sealing: Enabling Sustainability

Mono-materials and paper composites for packaging are increasingly in demand and the number of inquiries regarding new recyclable materials is increasing at the ultrasonic laboratory of Herrmann Ultraschall. Many of the major food companies have set themselves high sustainability targets and are testing the new materials.

News

And the winner is... Herrmann Ultrasonics!

Herrmann Ultrasonics has been named the winner of the Electrolux Supplier Innovation Award for Food Preservation. The company was awarded the top honor out of an initial 40,000 suppliers world-wide at the annual Supplier Awards event, held in Stockholm a few weeks ago.

Ultrasonic welding of bio-based plastics

As of now there are few inquiries for the welding of recycled materials, ie plastics that already have been processed once or more before. The weldability must be determined empirically in the test laboratory.

News

Circular economy

Ultrasonic technology can also deliver good sealing results with narrow process limits, especially with regard to tightness and visual appearance. The thermal expansion is kept to a minimum. Thermal processes demonstrate disadvantages of excessive heat input, especially in the continuous welding of film webs.
