Leakage proof

Packing wet pet food with 20 x less waste


Valuetainable – for Wet Pet Food

Hermetic sealing

In the packaging of food for people, thightness plays just an important role as it does when it comes to stand-up pouches. As packaging leaks mean costs in terms of materials, financial resources and consumer trust, our technology guarantees tight seams through the use of ultrasonic sealing. By doing so, wet pet food is packaged very securely, i. e. the use of ultrasonics can reduce the number of leaking packs to a minimum of 0.001 %.

How the magic happens

Added value in a nutshell

  • Ultrasonic sealing ensures a completely tight packaging seal, even if there are remnants of the filling goods present in the seam area.
  • Regardless of the consistency of the filling good (solid, moist, or liquid), the vibrations of ultrasonics reliably displace residues from the sealing zone during the sealing process.
  • The amount of leaking packages can be reduced considerably, as well as customer complaints.
