Internal Valve Side Gusset Pouch
We are aware that tea and coffee require very specific conditions in order to keep their peak flavour and quality. Our special pouches include an internal valve, which helps preserving the freshness of your delicacies by removing the excess gas inside the bag. Thanks to the valve we are able to protect your product from humidity and oxygenation, which are common causes of lowering the long-term quality of tea and coffee. Our special pouches are available in four distinct colours: silver, gold, maroon and black.

How does the valve work?
The valve consists of a valve body and a membrane. Even a very slight overpressure in the package causes the membrane to bulge. As the pressure increases, the membrane rises at one valve location until a channel is formed, through which the gases can escape to the outside. After the gas has been successfully vented and the pressure is compensated, the valve closes and the membrane lies once again against the valve body. The content is thus reliably protected against external oxidation.
