Vacuum packing removes air or oxygen from the package prior to sealing. This involves placing the product in a plastic bag, removing air from the inside, and sealing the pack.  The vacuum sealer removes oxygen to extend the shelf life of foods and or reduce the size of the package.
Aerobic bacteria requires oxygen, the vacuum packing will remove this oxygen from inside the bag to reduce the growth of the bacteria slowing down decay. Use the vacuum sealer for fresh or dried foods to extend the shelf life for vegetables, meats, fish, nuts, cooked meat, cheese, coffee, etc.
