Degassing Valve

You've seen valves on many of the pouches you have

A degassing valve, also called a one-way degassing valve, allows gases produced by oxygen in the bag to escape, preventing the bag from bursting due to the built up pressure. Bags designed with a one-way degassing valve help extend product freshness. These are commonly used for rigid coffee packaging but can be used in any pouch application where the bag's products emit gas, such as kimchi or sauerkraut.

Our premium degassing valves are imported from Switzerland for the highest level of product protection and are considered the world's leading degassing valve from WIPF AG.

Degassing valves allow the built of gas inside the bags to be released but do not allow normal air to enter the bags within the performance limits of the valves. We offer several types, versions, and sizes to meet the different capacity needs of your items.

What is Degassing?

When talking about a degassing coffee valve, we are mainly talking about coffee beans. As you might know, roasting is a much-needed process when dealing with coffee. Green coffee beans are soft and mushy with a grassy smell. Through roasting, the beans unlock that rich aroma and flavor we all love. Along with it, gases are formed inside the beans and are released for several days. In the first 24 hours, almost 40% of gases (mainly carbon dioxide) leave the beans. Degassing can be a challenge when it comes to packaging, and that's when the degassing valve steps in.

What is a Degassing Valve?

A degassing valve is a one-way valve that allows the gas released from the beans to be expelled from the bag without letting air come inside it. This helps promote freshness and keeps the products inside the package free from contaminants for a long time.

Coffee Bags with Degassing Valve

Due to degassing process, coffee beans release gases even after being packaged. The coffee package can become bulged and eventually burst, provoking loss of packaging and product, even hurting workers and customers. A valve will prevent that by letting the gases out.

Since it is a one-way valve, it won't allow the outside air to come in. That will avoid oxidation and moisture, keeping the beans fresher for longer, preserving the original aroma and flavor.

Stand up gusseted bag

Stand up pouches are manufactured with a bottom gusset which, when deployed, allows the bag to stand up on the shelf in a store instead of laying down like flat pouches. Commonly referred to as SUPs, this gusseted bag has more space than a 3-seal with the same outer dimensions

Side Gusseted

Side gusseted pouches are an older and more traditional style. This square bottom pouch is trendy in the coffee industry, can be used with most closure options, and it's fully printable. Differently from the stand up pouch, this bag will only be standing after it is loaded.
