One way degassing valve 

The one way degassing valve is especially suitable for bean coffee. The one way degassing coffee valve effectively vents CO2 gas build-up while sealing-out environmental oxygen, moisture and contaminants.Fresh roasted coffees emit large amounts of CO2 for several days after roasting. At the same time, coffee requires protection from air to maintain its fresh roasted taste. A coffee roaster must seal his coffee in a package that will (1) not allow air to enter the bag to spoil freshness, and (2) will allow the COemitted from coffee to escape out of the bag.Our one way degassing coffee valve will help release the gas while preventing air entering the bags.Installing one way degassing valve is necessary for coffee packaging bags. This allows roasters to pack freshly roasted coffee immediately without the worry of having the bag burst open due to trapped air.


Application of one way degassing valve  

The most common application of the one-way degassing valve is for fresh roasted coffee.

Another application is for the release of entrapped air for stacking and producing stable shipping pallets,including large flexible packages for pet food, animal nutrition, plastic resin, and agricultural chemicals.
