Valve Sealed Bags What are they and Why are they Used

Coffee is an important part of the day for many people. More than half of all Americans over the age of 18 drink coffee each day with the average amount of coffee being just a little more than 3 cups. No matter what the reason is for choosing coffee, everyone can agree on one thing. The packaging of coffee bags is most definitely distinct and unique. This isn’t so much done just for custom printed coffee bags, or paper coffee bags. Valve sealed bags, or coffee bags with valve seals serve a purpose. Read below to see what some of those reasons are and what purpose the valve on valve sealed bags holds for consumers.


Yes coffee beans are typically roasted before being placed into a bag, but they still emit gases after bagging and during the shipping process. These gases can last for up to two weeks. If there was no valve on your coffee bag then these gases would have no where to go and would be forced to remain in the same bag as your coffee. This can make for some stale and gross coffee.

When it Works

The valve that is on valve sealed bags is only good until you open the bag. Once you open the bag, this valve serves no purpose. Closing the bag doesn’t help it either. This is why it’s important to look for a coffee bag that is still completely sealed before deciding which one to purchase. Purchasing a bag that the seal has been broken on, means the valve no longer works, which compromises the taste of your coffee.

It Works Perfectly

This hole makes perfect sense for a coffee pouch because it does exactly what it was designed to do. Little holes will not work, because they will get clogged with dirt and blocked. The gases would then fill up the bag of coffee and then possibly burst. The vacuum seal works to let air out without letting air in. This protects your coffee and the bag its in.

The next time you buy coffee look really close at the bag. You will notice that each one has a vacuum seal on it. Take time to look at each seal and see where it is placed. See how big it is, and how different size bags have different size valves. Each valve serves a purpose and now that you know what they are for, it will be interesting for you to see each one.
