Vacuum seal bags are specially designed storage bags that remove air from the inside before sealing. This process helps to preserve food by slowing down spoilage and preventing freezer burn. They are commonly used for storing meats, vegetables, and leftovers, extending their shelf life significantly. These bags work with a vacuum sealer machine, which sucks out the air and seals the bag tightly. Vacuum seal bags are also useful for organizing items, such as clothing or camping gear, by compressing them to save space. They are available in various sizes to accommodate different storage needs.
