Benefits of Sonixs® Sealing Technology:


  • Proven to provide a reliably stronger seal, reducing cost and amount of strap needed per package with no negative impact on package quality or security.
  • Increased seal strength allows strapped products to withstand significant stress, enabling the use of thinner, narrower, less expensive strapping materials without loss of performance.
  • Conserves electricity by only using power during the strapping cycle compared to a heat-sealing system that uses constant resources.
  • Sonixs® sonotrode and generator include a 2-year warranty.


  • No smoke, fumes or smells.
  • Low noise levels.
  • Seals PET strap (made from recycled material, and 100% recyclable) providing customers an economical and more environmentally friendly choice for strapping.
  • Uses energy only during the sealing process. No warm-up required.


  • Innovative lever-style gripper, knife, and sonotrode drive with sealed bearing construction provide maximum durability with less wear and tear.
  • Minimal maintenance is required as no residues are created during the sealing process.
  • Seals both PP and PET strapping with broad tension ranges, ensuring tight straps and secure bundles under all conditions.
  • Easily switch between PP and PET strap when needed. (Minor adjustments and part change may be required.)
  • The self-calibrating system monitors major parameters before every seal for consistent sealing in any environment.
  • Our tool-less sealing head maintenance for easy and fast maintenance within 30 seconds.


Increase Flexibility, Lower Overhead Costs

In ultrasonic strap sealing, low-amplitude, high-frequency vibrations transfer to both ends of the plastic strapping material. The custom sonotrode, the heart of the high-speed sealing unit, joins the strap ends for a superior, solid bond and consistent strap seals that maintain strength to keep your products secure and protected. Its unique seal impression gives our customers the ability to identify and deter tampering easily.

Unlike heat seal systems, Sonixs® strap seals are made without the use of high-temperature components, reducing energy costs, improving safety, and generating lower emissions. The process-controlled system is operator-friendly, requiring minimal maintenance and reduced parts usage. Using ultrasonic sealing has also given our customers the ability to use PET in bundling applications, giving increased flexibility when it comes to a more sustainable plastic strap choice.
