Internal Valve Side Gusset Pouch

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 four distinct colors: silver, gold, maroon and black.

- Available capacities: 250 g, 500 g, 1000 g 

- Wide range of colors: black, gold, silver and maroon

- This type of bags protects your products from:

                - oxygen - which affects the airing and oxidation

                - heat and humidity - accelerate spoilage

                - foreign smell - easily lead to changing the flavour and natural fragrance of products


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.


 - removes excessive gases inside the pouch

Translucent Fully Biodegradable Stand Up with Zip Lock

We believe that organic products require special packaging. This translucent, stand up pouch is eye-catching and perfect to present your product on the shelf, as the customer can instantly check the quality of your product inside the bag. Freshness of your product is secured by a heat seal on the top and a resealable zip lock on the top, creating a good barrier against external factors. But the most important trait of this bag is full biodegradability – it completely decomposes in just 10 weeks, including the zip lock.
