Saving resources without compromises


Valuetainable – sustainable and profitable for brands and everyone who packages products.

Emission free future 

Valuetainable is about prioritizing conservation in areas that truly matter, such as energy, greenhouse gas emissions, raw materials, food, and, above all, costs.

Our use of Ultrasonic sealing in flexible packaging is a catalyst for greater sustainability for brands, packaging production, the circular economy, and economic benefits for all. As a "valuetainable company", we combine what is generally seen as distinct.

Food is better protected and kept fresh longer by good packaging. Ultrasonic sealing technology has become an established and economic alternative to heat sealing.

Sealing through contamination

Tight sealing under difficult conditions 

With ultrasonic sealing, packages are sealed 100 % tightly even if there are residues of the contents in the seam area. 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.

Contamination during thermal sealing processes compromises the tightness of the packaging.


Realize less headspace and save material

Stand-up Pouches

Ultrasonic sealing can create a hermetic sealing even with product in the sealing area. This makes the filling with more product possible and reduces the headspace without the risk of having more untight packages! Alternatively, it is also possible to reduce the packaging size keeping the same volume to save material.

What do elephants have to do with cat food?

A customer packs moist, chunky cat food in a stand-up pouch. This repeatedly resulted in defective packaging that had to be disposed of. By switching to our reliable sealing technology, the number of leaking packs was able to be reduced from 0.05 % to 0.001 %.

That might not sound like much, but it’s actually quite substantial: every day, more than 4.4 tons of cat food are saved from disposal – equivalent to the weight of a full-grown elephant.


Ultrasonic sealing is suitable for a wide range of applications.

Valuable for different applications

Ultrasonic sealing offers solutions to meet the demands of the future

Legal regulation for packaging

Whether you are looking to limit overpackaging, increase the product-specific recyclate usage rate, or replace multilayer packaging with new monomaterials, ultrasonic sealing offers a future-proof solution to meet your packaging needs.

EU-wide standards for over-packing will define maximum allowed empty space in packaging and ban certain forms of unnecessary packaging. The Ultrasonic technology allows to minimize the sealing area and as a result reduces unnecessary packaging space.

In the future an increased use of recycled plastics in packaging material is mandatory to meet the legal regulations and to decrease the use of virgin materials.

In order to meet future packaging recycling rates monomeric materials will become more and more a standard for packaging material. As monomeric material is quite sensible towards heat Ultrasonic offers here the right technology for a tight and reliable sealing process.


How ultrasonic sealing works


In ultrasonic welding, melt is created in the packaging material itself by introducing mechanical vibrations into the packaging material using a sonotrode. These vibrations generate friction between the molecular chains and the interfaces of the packaging material layers, resulting in localized melting. The use of cold ultrasonic tools enables rapid cooling, allowing for immediate loading of the produced seam. This minimizes the thermal load on the materials and the packaged goods.
