The coffee bags with valve is also called coffee air valve bag. The content of this coffee bag with valve is “coffee beans”. After roasting, the coffee beans will continue to emit carbon dioxide gas for a long period of time and the volume is also relatively large. If you use a packaging bag with a strong sealing performance, these carbon dioxide gases cannot be discharged , and the phenomenon of bursting will occur. The coffee bags with valve are more conducive to the discharge of these gases.
However, in order to maintain the dryness and taste, the coffee beans still need to be blocked from the outside oxygen. Will it leak, if the bag installed such an valve? It is related to the particularity of this “exhaust valve”. The air valve installed on the coffee bag is also called “one-way vent valve” , The gas can only be discharged in one direction. There is not a relationship of mutual circulation.
