What's the vent on coffee bags for?

After roasted, coffee beans release a lot of carbon dioxide gas, which is several times the volume of coffee beans. If the gas is not released out from the bag timely, coffee bag will burst when the air in bag reach a certain degree. One-way vent valve is not only able to remove the carbon dioxide gas from the bag, but also prevents oxygen from entering bag to oxidize the coffee beans, which ensures the fresh quality of coffee beans and removes the risk that coffee bags bulge or burst.

Besides, since there are vent valves in coffee bags, customers can squeeze the bags directly when they buy coffee. Customers will smell the aroma directly emanated from the bags to better confirm the freshness and quality of coffee. Therefore, it is very essential to install one-way vent valve in coffee bags. Professional coffee bags definitely are installed with one-way vent valves.
