Aroma protection - how do degassing valves work

Some products, such as coffee or fresh dough, continue to outgas even in airtight bags or tins.
Our degassing valves remove this excess gas and at the same time prevent 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.

Valves are applied without heat using an ultrasonic process, so that in addition to maximum efficiency with up to 100 spm (sealings per minute), mono material can also be processed easily.

Minimize downtimes thanks to proven valve supply

With the CVA applicators, you get a reliable valve supply without malfunctions, which is carried out very gently and mechanically, thus achieving machine availability of over 98%. You also save time and protect your employees, as refilling takes place ergonomically at ground level.

Customized engineering with flexible solutions
