Vacuum Seal Bags
Vacuum sealing foods such as meat, cheese, and vegetables has become a widely used and trusted means of preserving foods for long periods of time. Food is typically frozen once it is sealed or the food is dried prior to sealing.
This technique is excellent for removing freezer burn from foods and prevents any sort of airborne mold or bacteria from reaching your food. Vacuum sealing is also a great way to preserve other items such as silver coins that would otherwise slowly corrode.
