We are aware that tea and coffee require very specific conditions in order to keep its peak flavor 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 three distinct colors: silver, gold and maroon.

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 overpressure is increasing, 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 compensated, the valve closes and the membrane lies once again against the valve body. The content is thus reliably protected against external oxidation.
