Custom Bags with Degassing Valve

Degassing Valve

You've seen valves on many of the pouches you have purchased. A Degassing valve, also called one-way valve, allows gases produced in the bag to escape, preventing the bag from bursting. These are commonly used at coffee bags but can be used in any pouch application where the bag's products emit gas, such as Kimchi.


Degassing valves allow the built of gas inside the bags to be released but do not allow normal air from entering the bags within the performance limits of the valves. We offer several versions to meet different needs and sizes of pouches.


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

What is degassing?


When talking about degassing, 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 gases released from the beans to be expelled from the bag without letting air come inside it.


Why do you need a valve at coffee bags?


Due to degassing process, coffee beans release gases even after being packaged. The coffee bag 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.


Another plus of having the degassing valve is faster packaging. Two-thirds of CO2 is released from the beans within the first hour after the roasting process. With valved bags, you can start packaging your products in coffee bags right away, being less time-consuming.


Custom Valve Coffee Packaging


From stand up gusseted bags to spouted ones, you can customize your bag in any way you think is the best for your brand and product.

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.


Different materials

We have several materials for you to choose from, depending on your needs.


  • CareClear is a flexible, durable, and robust barrier film due to BoPET and high nylon content. Despite having two layers of different polymers, CareClear is crystal clear, making it a great choice if you want to add die-cut windows to your bag.


  • CareSilver is our line of metallized PET that provides extra protection against moisture and oxidation. With high tensile strength, it's more affordable than aluminum foil packaging.


  • CareFoil is our line of flexible foil barrier packaging materials. We offer several variations of foil to meet the needs of different applications. This metallized material provides the best barrier to both oxygen and water.


  • CareKraft is our high barrier solution with kraft paper. It appears as paper bags but with high resistency. It's commonly used on coffee bags and when seeking a natural earthly look.

Features

You can add many features and seals in your bags: hang hole, tear notch, lip and seal, zippers, tin tie. The latter is very popular on coffee bags.


Printing

We provide two types of printing:

  • Digital printing – great for highly detailed images or if you want to choose a particular color. You can print a few copies for testing or roll printing.
  • Plate printing - following CMYK color, has a higher setup cost but the lowest cost per unit, making it an excellent choice for wholesale with roll printing.
