Solutions for your high-performance and process-reliable application

Inside valves VIS/VAP

Thanks to proven ultrasonic technology, up to 100 valves per minute are sealed on the inside of the packaging material, even if made with mono-materials.

Outside valves V45

The right valve for every application: achieve maximum quantities with up to 120 self-adhesive valves per minute on the outside of all packaging materials.

Applicators & Engineering

Maximum flexibility for any application - all packaging materials and all valve types are easily integrated into Syntegon packaging machines or machines from other brands with the CVA applicators.

If the aroma vanishes, even the best coffee only adds up to a pile of beans.

With our recyclable aroma protection valves, coffee can be packaged freshly roasted and without interim storage in to sustainable packages. The valves allow the reliable and positive escape of roasting gasses from gastight packages.

For the perfect taste of coffee, aroma protection is a central component in production and processing. Here you will find information about Package Maker PMX and the different types of packaging.

Some products, such as coffee or fresh dough, continue to release gas even in airtight bags or cans. Our degassing valves discharge this excess gas while preventing oxygen from entering the packaging and spoiling the product. This allows your customers to enjoy the full product flavor and significantly extends the shelf life. You also save on storage costs, as degassed packaging takes up less space and is less sensitive to pressure.

Sustainable solution with ultrasonic technology

Using ultrasonic technology, valves are applied without heat, so in addition to maximum efficiency at up to 100 spm (sealings per minute), mono material can also be processed easily.

Minimize downtimes thanks to proven valve delivery system

With the CVA applicators, you get reliable valve feed without malfunctions through very gentle mechanical handling, thus achieving machine availability of over 98%. In addition, you save time and protect your employees, as refilling is carried out ergonomically at ground level.

Customized engineering with flexible solutions

Do you already have a packaging machine or a valve applicator in operation? We will be happy to advise you on your individual valve solution, which can also be retrofitted to existing applications.
