Coffee Bag With Valve
If the coffee beans are packed in a sealed bag, there is no channel for releasing gas, and they continue to expand. Once in this state for too long, the carbon dioxide molecules accumulated in the bag will form oxides on the surface of the coffee beans. Directly affects the freshness of coffee beans. The coffee flavor dissipates according to time, which makes the effect of water saturation during the brewing process worse, and the coffee liquid with insufficient taste is extracted. So bn pack coffee bags can keep the best flavor of coffee beans and taste the taste from the place of origin.

Most of the coffee beans I bought will touch a hard thing on the bag, and there are small holes on it. What does this mean? Why is there this thing on the bean bag?
The coffee bean bag is hard, with a small hole, we call it a one-way exhaust valve.
After the coffee beans are roasted, the coffee beans will contain carbon dioxide, especially in the few days after they are roasted, the coffee beans will release more gas. If the bag is completely sealed, you will find that the bean bag is bulging. Especially some dark roasted coffee beans, bulging and lovely. But with the one-way exhaust valve, the gas in the bean bag can be exhausted from this place, reducing the situation of excessive expansion of the bean bag.
Why a one-way exhaust valve?
Because this exhaust valve can only let the internal gas out, the external gas can not get in. Oxygen and moisture contained in the air are very necessary for us humans, but for coffee beans, they are things that damage themselves. Oxygen and moisture will shorten the shelf life of coffee beans and make it worse. Therefore, another function of the one-way exhaust valve is to prevent oxygen and moisture from entering to a certain extent.
There are many kinds of coffee one-way exhaust valves, there are particle styles, patch-type one-way exhaust valves, and particle one-way exhaust valves. There are also several types of one-way exhaust valves. The two well-differentiated ones are the 20MM diameter with filter. And the particle one-way exhaust valve without filter screen, this kind of particle one-way exhaust valve requires valve press equipment to install, bn pack can provide a variety of coffee packaging bags with valves, allowing customers more choices , more convenient to pack.
