Vacuum Sealers Explained
Vacuum Sealers remove oxygen from a package prior to sealing the bag. By removing oxygen from the package, vacuum sealing can extend the life of a food package or prevent rust of industrial items. Some vacuum sealers also provide gas purge/gas flush which can flush your pouch with nitrogen to ensure the complete removal of any oxygen in your pouch. Barrier type of bags must be used to ensure a proper vacuum...some sealers such as the external vacuum sealer require special channel or embossed bags in order to vacuum and seal. There are three major categories of vacuum sealers: external vacuum sealer, nozzle vacuum sealer, and the chamber vacuum sealer. We carry vacuum sealers in all three categories.
