What are vacuum sealers?

vacuum sealersVacuum sealers are the ones which help in vacuum packaging. Vacuum packaging is a method of packaging which removes air from the package before sealing. In this method the items are placed in a plastic film and the air is removed from inside and the package is sealed. Sometimes Shrink Film is used to give tight fit to the contents. The main intention of vacuum packing is to remove oxygen from the container so as to extend the shelf life of the food items. By removing the atmospheric oxygen, the growth of the aerobic bacteria or fungus is limited and also prevents the evaporation of volatile substances.

On a more short term basis, vacuum packing can also be used to store fresh foods, such as meats, vegetables, and liquids, because it inhibits bacterial growth. For delicate food items which might be crushed by the vacuum packing process (such as potato chips), an alternative is to replace the interior gas with nitrogen. This inhibits deterioration due to the removal of oxygen and has the same effect.
