When the gas generated by the product sealed in the bag makes the inside of the bag reach to a certain pressure, the gas can be pushed from the inside to the outside to open the one way degassing valve sheet, and the excess gas is discharged outward. When the pressure in the bag reduced to the level which is not enough to open the valve, the valve will close automatically. Meanwhile, the valve will automatically open only when the pressure inside the bag is higher than the pressure outside the bag, otherwise, it will not open, and the air outside will not enter to the bag.
A degassing valve is a one-way vent that allows coffee beans and ground coffee to slowly release carbon dioxide (CO2) and other volatile gases from the bag, without coming into contact with the air outside.
