 Mylar coffee bags

Most people cannot imagine starting a new day without having a cup of coffee. There are many factors go into making a perfect cup of coffee. Among which food packaging bags plays a significant role. After putting the roasted coffee beans into Mylar coffee bags , there are lots of carton dioxide would be released from the bag. Not only the carbon dioxide will cause the coffee bags explosion, but also it will make the coffee beans oxidation which affect the original taste.


Taking into account this problem, we add a one way degassing valve which is helpful to release the carbon dioxide outside of the bag. Meanwhile, it also could stop releasing the carbon dioxide outside of the bag after the internal pressure reach a lower level for keeping the coffee aroma in the coffee bag. This is the reason that you could smell the coffee aroma when you approaching the coffee in the supermarket. Nowadays, degassing valve especially has been widely applied in many foil pouch packaging.
