Air within the hermetic storage is sucked out leaving little oxygen for living organisms to survive on. Suction of the air creates a low atmospheric pressure which is unfriendly and unconducive for invaders (i.e. insects). Gas Hermetic storage – filling the hermetic storage facility with carbon dioxide to expedite oxygen depletion.
The intent of vacuum packing is usually to remove oxygen from the container to extend the shelf life of foods and, with flexible package forms, to reduce the volume of the contents and package. [ 2 ] Vacuum packing reduces atmospheric oxygen, limiting the growth of aerobic bacteria or fungi , and preventing the evaporation of volatile components.
