Internal valve uses:

- releases excess gases from inside the pouch
- protects contents from oxygen exposure
- preserves the product’s original flavour and aroma for longer

How does the valve work?

The valve is made up of a body and a membrane. Even the slightest overpressure inside the pouch causes the membrane to bulge. As the pressure increases, the membrane lifts at one point, creating a small channel through which the gases can escape. Once the pressure has been released and equalised, the valve closes, and the membrane returns to its original position against the valve body. This process reliably protects the contents from external oxidation.
