Vacuum Sealer Information

How do vacuum sealers make food last longer?

1. The reduced oxygen content within the vacuum package slows down food break down. Most oxygen can be removed by creating a vacuum within the package.

2. Vacuum bags are made from poly woven materials to keep oxygen from permeating through the package. Standard poly bags will not hold a vacuum.

3. After oxygen is removed from the package, an airtight seal is made. The seal is important to ensure the package will continue to hold a vacuum during storage.

Vacuum Sealers and Modified Atmosphere Packaging

After a vacuum sealer completes the seal of a packaged product, the product is enclosed in modified atmospheric packaging. The atmosphere within the package is modified from the external atmosphere. This modification can be done in many different ways to help preserve consumable and non-consumable products.

A standard vacuum sealer that removes air from a vacuum bag is reducing the oxygen content within the package. This reduction in oxygen is a form of modified atmosphere packaging. Some vacuum sealers offer a gas flush option to even further modify the atmosphere within the package. The gas purge inserts a gas into the package to help with extending the product shelf life.

Nitrogen is a common gas used in gas flushing. It makes up 78% of the air we breathe. A set amount of nitrogen is flushed into a vacuum bag to push out oxygen and leave nitrogen within the package. The final package contains 99.9% of nitrogen surrounding the products. This atmospheric change can increase product shelf life and reduce food spoilage.   

Vacuum Sealers 

Commercial Vacuum Sealer

A vacuum sealer is a machine designed to remove oxygen from a package. After the air is removed, heat is used to seal off the package. Vacuum sealers can come in a variety of different forms and offer many features. Most all vacuum sealers offer the basic function of removing oxygen and sealing open packages. The right vacuum sealer will enable the desired efficiency and packaging settings to meet the needs of each specific goal. The products being wrapped will help determine the type of machine needed.

Nozzle sealers are the most popular vacuum sealers. Most home use vacuum sealers have a nozzle that is inserted into the bag to remove air. Other machines including thermoforming, skin packaging and chamber sealers are also used to attain a full vacuum. Each type of machine has advantages over 

Vacuum Sealers with Gas Purge

Vacuum sealer with gas flush

Vacuum sealers with gas purge enable users to introduce a gas mixture into the vacuum bag. The gas mixture is often an inert gas such as nitrogen. Gas purge is most often found in food packaging applications. The sealer removes oxygen from the package in inserts nitrogen to prolong the shelf life of the product being packaged. Depending on the product being packaged and the proper modified atmosphere within the package, shelf life can be prolonged 2 to 10 times longer.

All vacuum sealers with gas purge offer the same qualities as vacuum sealers with external compressors. A strong and sturdy sealing bar enables the sealing of vacuum bags up to an 8 mil thickness. The main difference between the two sealers is the vacuum sealer with gas purge is hooked up to two external tanks. One tank is the air compressor with at least a 15-gallon tank and the other is a bottle of inert gas, which is commonly nitrogen. Nitrogen bottles can be found at any local welding supply store.

Self Contained Vacuum Sealers

Self contained vacuum sealers come with built-in compressors for removing air and a gas flush option. The advantage of the self contained vacuum sealers is an all-in-one unit to save space. Home use vacuum sealers are self contained machines that do not require additional equipment for set up. The simplicity and ability to save space has many advantages over machines with external compressors.

Some contained vacuum sealers can be loud. Be sure the noise of the machine when in use will not disturb people in the area of operation. The noise and the internal compressor inside the sealer can be two major drawbacks. If the compressor begins to go out, it can be costly to fix. Machines with external compressors can quickly be replaced if problems arise.

Chamber Vacuum Sealers  

Chamber vacuum sealers are the perfect option for vacuum packaging liquids or products with liquids. Bags are placed inside the chamber and a vacuum is created within the chamber. The artificial vacuum pushes air out of the bag without spilling liquids. Once the desired vacuum is reached, the sealer lowers to make a seal. Multiple packages can also be sealed at once with a chamber sealer.
