Why do you want to add the one way exhaust valve to coffee bag? What is the role of the exhaust valve?


1. The roasted coffee beans are sealed in aluminum foil bags with one way exhaust valve, to prevent the entry of external oxygen and moisture, and cause the fragrance to dissipate and taste quickly.


2. The roasted coffee beans will emit carbon dioxide (CO2) naturally. If it is stored in the bag, it will affect the quality of the coffee beans. The holes on the exhaust valve on the bag can discharge CO2 from the bag, and when customers buy the coffee, they also can squeeze the bag to smell fragrance of the coffee.


3. The one way exhaust valve can obstruct the light and air go into the bag, let the coffee beans in the best save package status. so that the coffee beans can maintain the fresh original flavor.
