Coffee beans will continuously release carbon dioxide several times the volume of coffee beans after roasting. In order to prevent coffee packaging from bursting and isolating from sunlight oxygen, a one-way air evacuation valve was designed on the coffee packaging bag to discharge excess carbon dioxide out of the bag.
In addition, the one-way air evacauation valve can also block the oxygen outside the coffee bag into the bag, so as to avoid the oxidation of coffee beans and lead to the rapid release of fragrance, thus ensuring the same flavor of coffee beans. Of course, when you buy coffee, you can squeeze the packaging bag and smell the coffee through the coffee exhaust valve.
