How to live in a Sustainable World

Everyone in the Industry talks about moving to more sustainable solutions – but when? Consumers are unhappy about the progress that has been achieved so far.

The reality is - in order to make the change actually happen, it’s key to have a tangible benefit. In order to live in a sustainable world we need smart solutions that are able to provide all benefits like more efficiency, decrease in costs and using sustainable materials. 

Join all of our partners and us on the mission to provide real applicable solutions to make the world a better place right now. This is what our Food Packaging solutions stand for: 
Connecting efficiency with sustainability

Connecting efficiency with sustainability

Increased Efficiency means:

  • Higher throughput and machine uptime, since hermetic sealing is possible even with product residue in the seal area. Additionally faster startup of the machine, since the tools are operating cold
  • Reducing or eliminating manual labor by integrated sealing process control and easy cleaning
  • Higher cycle rates, since tools can close earlier even if splashing product is in the seam

Sustainability means:

  • Economic use of product since more bags will be hermetic.
  • Less material consumption, since up to 50% less headspace is possible and much thinner sealing lines compared to heat sealing
  • Happier consumers by using sustainable materials and achieving longer shelf life through higher quality seals
  • Reduced energy consumption compared to heat seal, because the tools are cold

The food packaging sealers are used for products with thermoplastic sealing layers, such as capsules, pouches, drink cartons, cups and trays. That also includes easy sealing of sustainable materials such as mono-materials, bioplastics, coated paper and recycled materials, even with small process windows.

Ultrasonic sealing of food product packaging fulfills all criteria of process optimization and validation crucial to companies in this sector.


Application Engineering

Successful ultrasonic solutions

Film packaging

The advantages of using ultrasonic sealing for closing bags containing wet products are outstanding. Here is how the solution makes the production more efficient, while reducing waste and cost:

  • Higher quality hermetic sealing, because it is possible to safely push product residues out of the seal area
  • Significantly higher machine throughput, by providing more hermetically sealed bags
  • Decisively quick ROI, especially for wet, pasty or powdery products, because an automated line and a more efficient production are lowering your production costs
  • Using the product itself more economically, by decreasing food waste
  • More efficient use of film material, by reducing headspace

Ultrasonics provides these advantages for stand-up pouches, chained bags and sachets, both at longitudinal and transverse joints, in intermittent and continuous applications.

Capsules and Cups

The production of capsules and cups benefits from connecting a more efficient production with sustainable materials and economical usage of product. Here are the reasons:

  • Achieved output rates are the highest, compared to other plastic cup sealer technologies
  • The fine aroma of food products like coffee is preserved by using cold sealing tools
  • Products are used more efficiently, because of the ability to seal through powder residues in the seam
  • Process is safer and traceable, with the integrated quality control
  • Efficient use of machine space, cutting and capsule sealing takes place in one station

The cup sealer solutions we offer are for sealing of lid film onto capsules, sealing of filter materials, and welding of injection-molded lids onto injection molded plastic parts. Ultrasonic sealing is possible for all common sustainable thermoplastic materials.

Cartons

High output rates, process stability and elimination of aluminum makes ultrasonic sealing the more efficient and more sustainable solution for sealing of paper and carton packaging. Additionally the production benefits from:

  • Shorter sealing times and less energy requirements, since the heat buildup starts from the inside out
  • Safer sealing and wider process windows for fiber materials, since tools are cold and less of a thermal stress is necessary
  • Consistent high sealing quality, achieved by integrated sealing feedback

We offer ultrasonic sealing to weld coated cartons like in gable top sealing for drink packaging, welding of rigid parts like spouts and valves against carton.  

Blister packs, trays, bowls

On PET welding applications in particular, ultrasonic sealing results in an increase in production output because it quickly reaches the high melting point. The technology has the potential to process many more units per hour than other systems, especially for mono-materials.

Spouts, valves, zippers

In order to integrate these additional features to packaging, these also need to be made from the same sustainable materials. This is achieved using ultrasonic sealing, and provides these additional benefits:

  • Keeps barrier properties of attached film materials, since the vibration only impacts the actual sealing layer
  • Clean appearance without film shrinkage, because low thermal load is necessary

With ultrasonics, fast and safe welding of injection molded degassing valves or spouts on films of any type is possible. Moreover, ultrasonics allows for safe integration of zippers for re-sealable pouches and welding of the zipper ends (zipper-crushing).

Tea bags

All welding steps of tea bag production are efficient using ultrasonic sealing; this even includes adding the string and the label to it. For a clean look, it is possible to cut and seal at the same time for this application. Even sealing of sustainable materials such as bioplastics and PLA are possible.

Cutting

Clean cuts without deforming the product: this is easily possible with ultrasonic. As a result, you not only increase the quality of your products, but also reduce waste and therefore your costs. The sonotrode precisely separates the food without leaving any remains on the cutting tool. This also prevents any smearing, resulting in a visually perfect result. Our cutting sonotrodes are made to have a longer lifetime and durability.


Sealing through contamination

  • With ultrasonic sealing, packages are sealed 100 % tightly even if there is product residue 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.
