Aroma Protection: Ensure freshness and extend shelf life

Degassing Valve Solutions for Fresh Dough, Yeast Products, Coffee & Beyond

Your packaging is essential when it comes to the quality of your oxygen-sensitive product. We make sure it keeps its quality – all the way to the shelf.

Dough and Coffee continue to release CO₂ long after it's sealed. Without the right valve solution, that means blown up packages, lost aroma, and dissatisfied retail customers. Syntegon's internal degassing valves are engineered to solve exactly this – releasing excess gas while keeping oxygen out, preserving freshness and protecting your brand.

The Challenge: Packaging Products That Are Still Alive

Oxygen-sensitive products, like fresh dough or coffee, don’t stop working once it's packaged. It produces CO₂ continuously – building pressure, threatening package integrity, and accelerating spoilage if oxygen gets in.

The consequences without the right valve:

Burst or deformed retail packaging

Aroma loss and reduced product quality

Shorter shelf life = higher returns and waste

Increased storage sensitivity and logistics costs

Challenge accepted: Internal Degassing Valves – engineered for your active food products:
              Excess gas escapes continuously – no pressure build-up
Oxygen stays out – full aroma protection, extended shelf life
Degassed packaging is more compact and less pressure-sensitive – saving storage costs
Ultrasonic sealing enables gentle and fast processing
