Ever wondered what the small valve inside the coffee bag is for? Want to know why it exists, and its purpose? Our article below discusses why the coffee bag has a valve and what the valve does.
--What’s The purpose of a Coffee Bag Valve?
When you buy coffee beans, you may notice the circular valves on your coffee bag and wonder what they do. They are dedicated to keeping powdered beverages fresh, thereby maintaining their unique and wonderful aroma.
After the coffee beans are roasted, they will continuously emit a large amount of carbon dioxide for many hours. If there is no outlet for carbon dioxide in the sachet, the bag will expand and eventually burst. The valve is the only solution.
--How does the one-way coffee bag valve work?
One-way valve prevents harmful external elements from entering the packaging bag. At the same time, it will release air and gas in the bag. The one-way valve is designed to increase efficiency and coffee quality.
The one-way valve bag is not only suitable for coffee products, but also ideal for tea and other dry products.
All coffee valves are strictly tested to ensure that each valve meets the required standards. We work hard and constantly review our practices to improve quality and expand the products we offer.
