When buying coffee beans, many customers often see a white valve inside the packaging with some holes around it. Now let’s give a brief introduction of this valve.

The white valve is one way degassing valve, also called coffee degassing valve. The bag that packs the coffee beans has a silver membrane, so what functions of this two things are?

Actually, the baked coffee will release the carbon dioxide naturally. If the gas were stayed in the packaging, the quality of the coffee beans would be influenced. Sealed and packed with an aluminum foil bag can avoid coffee oxidation to produce odors, affecting the quality of coffee because one way degassing valve can discharge the produced carbon dioxide out of the package.

The difference between one way degassing valve and other products is that one way degassing valve with filter can isolate the influence of powder material on degassing valve, release the gas out of the package and prevent the inside solid (including dust) from getting out at the same time, guaranteeing to keep the outside air out of the bag.

The silver fil is similar to tin foil material. We professionally call it aluminum foil. Aluminum foil bag has the function of dampproof, licifuge, obstruction and also avoid exposure to light and air resulting in the aroma and oxidation of the beans.

Aluminum foil bag with one way degassing valve help to keep the air out and keep the beans fresh. Therefore, the package of coffee beans should have both aluminum foil and one way degassing valve.
