Main Purposes of a Gas Flush Chamber Vacuum Sealer
“Gas flushing is a user-friendly automated system… bringing your vacuum packaging experience to the next level!”
Vacuum Sealing is a reliable storage option providing the longest shelf life, preventing freezer burn, and increasing cooking options such as sous vide. However, this process can be damaging to fragile items due to the collapsing bag, but it can also fail to create the ideal atmosphere specific to that product. Consequently, gas flushing has become a helpful feature of any vacuum sealer. Depending on the product types and vacuum packaging endeavors, a gas flush vacuum sealer might be just the thing for you!

What is Gas Flush Vacuum Sealing?
Gas flushing is a user-friendly automated system that functions with the vacuum sealing process to provide a version of modified atmosphere packaging, bringing your vacuum packaging experience to the next level! Essentially, all vacuum sealers remove oxygen so aerobic bacteria do not grow and cause food spoilage. Gas flush vacuum sealers take the process a step further by replacing the oxygen with a nontoxic gas like nitrogen gas. This system creates an ideal atmosphere specific to the product for optimal shelf life and safe transportation.
How do Gas Flush Chamber Sealers Work?
Chamber vacuum sealers with a gas flush feature are constructed with valves next to the seal bar within the chamber. Once the oxygen is removed, these valves push the desired gas into the bag immediately after the oxygen has been drawn out. Tanks of the desired gas are installed within the body of the chamber vacuum sealer that can be switched out when necessary. Simply set the gas flush program specific to the vacuum sealer and you are good to go!
Benefits of Gas Flush Vacuum Sealing
Food Safety
Fragile Products: Simply drawing all the air from the package holding a fragile product such as chips or medical products could collapse or break the food even if you apply a minor vacuum draw. The gas flush feature allows the benefit of reducing the oxygen for food storage purposes and replacing it with an inert gas to keep the packages from collapsing and damaging the product.
Transportation: Primarily, the gas flush operation is utilized for commercial vacuum packaging that involves the transportation of the products. Vacuum sealing could leave any item susceptible to damage during transportation. However, gas flushing provides an alternative. Adding a gas creates space between the packaging and food products for a slight cushion to keep your product damage-free!
Decreases Labor Costs
Less Food Damage: As a domino effect of food safety, less food is damaged in transportation or storage. As a result, less money is spent replacing the waste.
Longer Storage Times: Some gases, such as CO2, are specifically added to increase shelf life depending on the item requirements. This means the product stays fresh even longer. Accordingly, you will spend less money replacing spoiled food.
Fresher Products
Additionally, some gases can be applied to save the natural color and structure of the product. A fresher product and appealing appearance increase the overall value while attracting your customers.
Getting Started & Selecting The Appropriate Gas For Your Application
Many gases are used during the vacuum sealing process for many different applications. Which gas is right for your application? This is where JVR Industries steps away, and where your local gas company can provide you with additional information. Your local gas company should be able to provide you with the type of gas for your specific application in a tank and a regulator.
CAUTION! Certain Uses of Gas Flush Can Be Dangerous!
JVR Industries has worked with a myriad of commercial companies that have navigated the waves of danger. In our 50+ years, we have seen a plethora of approaches, including the reintroduction of oxygen. The introduction of oxygen can raise some concerns due to its flammable properties. Please bear this in mind as you enter the gas flushing world. Using unorthodox approaches, such as oxygen, is a use-at-your-own-risk application.
Vacuum Seal Using the Right Equipment with Gas Flush
Many vacuum sealing machines are constructed with the gas flush capability and each style accordingly fulfills unique vacuum packaging needs. For example, options include external vacuum sealers, Rollstock vacuum packaging machines, a continuous band sealer, and chamber vacuum sealers. That’s an all-around wide variety, but each variance holds a purpose depending on someone’s priorities.
With 50-plus years of vacuum packaging experience, JVR Industries stands by the guaranteed effectiveness of chamber vacuum sealers that house an oil pump. An oil pump (read here), undoubtedly, provides the highest vacuum draw, pulling up to 99.8% of air from the pouches! If you pair this with a gas flush feature, you got yourself a winner of a machine!
