The role of the small holes in the coffee bag

The role of coffee bag: anti-swelling bag + guarantee coffee quality

1. Exhaust (anti-expansion bag):

After roasting, the coffee beans will continue to release carbon dioxide larger than the volume of the coffee beans for a period of time. In order to prevent the coffee bag from bursting and isolate it from sunlight and oxygen, a one-way exhaust valve is installed on the coffee packaging bag. , And drain the excess carbon dioxide out of the bag.

2. No air intake (coffee preservation):

In addition, the one-way exhaust valve can also block the oxygen outside the coffee bag from entering the bag, preventing the coffee beans from oxidizing and causing the aroma to quickly spread, thereby absolutely ensuring that the flavor of the coffee beans remains unchanged.

3. Additional function: smell the fragrance

Of course, you can also squeeze the packaging bag when buying coffee, and smell the aroma of coffee through the coffee exhaust valve!
