Best vacuum sealer for long term food storage. Just what can you use these sealers for? You can seal meats, vegetables, fruits, breads, cakes, and even liquids such as punch drinks, soups, and stews. Some sealers even have a sous vide feature and a marinate feature, so you’ll want to read the descriptions carefully to make sure you’re getting what you want. If some of these features aren’t that important to you, you can save a little money by finding another sealer.
