For coffee companies, maintaining the freshness, flavor, and aroma of coffee is crucial to delivering a premium product. One of the most effective ways to achieve this is by using a freshness valve (also known as a degassing valve) in coffee bags.
What is a Freshness Valve?
A freshness valve is a small, degassing valve installed on coffee bags that allows carbon dioxide (CO2) to escape while preventing oxygen from entering. This is especially important because freshly roasted coffee beans release CO2, and without a proper outlet, the bags can swell or even burst.
