One-way Degassing Valve is their secret to keep ing your cof fee fresh. Once the cof fee is roasted, it off-gasses the one-way degassing valve. This lets the CO2 com ing off of the beans out of the bag while simul ta ne ously not allow ing any of the oxy gen back in the bag.
In its most common application, the valve is used to release, from a container, gas emitted by a product (such as roasted coffee) while preventing air from entering the container and coming in contact with the product itself. Besides, it used in food bags, medical devical packaging bags, pet food bags. etc..
The product should be stored in its original packaging, out of direct sunlight. Excessive handling should be avoided.
