Our coffee bag use the WIPF valve that we imported from Swistzerland,which has 3 year warranty. WIPF valves can preserve the flavor and aroma of the coffee excellently.
A coffee valve is a small, one-way valve that is typically placed on coffee bags to allow carbon dioxide to escape while preventing outside air from entering the bag. This helps to maintain the freshness of the coffee beans by preventing oxidation and staleness.
The valve works by allowing the carbon dioxide gas that is naturally produced by coffee beans to escape the bag while preventing outside air from coming in. This is important because if the carbon dioxide is not allowed to escape, it can build up inside the bag and cause the bag to swell, potentially leading to a burst bag. On the other hand, if outside air is allowed into the bag, it can cause the coffee beans to become stale and lose their flavor.
Coffee valves are usually made of a thin, flexible material, such as a plastic or rubber, and are designed to be inserted into a small hole in the coffee bag. The valve is typically placed near the top of the bag, where it can allow gas to escape while still providing a barrier to outside air.
In summary, a coffee valve is an important component of coffee packaging that helps to maintain the freshness of the coffee beans by allowing carbon dioxide to escape while preventing outside air from entering the bag.
