Vacuum Sealers and the sealer bags that come with them have become a valuable combination for sealing cooked or uncooked food products, extracting air from inside the sealer bags and providing a moisture barrier that keeps sealed food fresher. Vacuum packed foods last longer and prevent freezer burn on meats stored in the freezer. Most sealer bags are BPA-free & safe to microwave, boil & freeze. Sealer bag rolls come in multiple widths; simply determine the length of bag you need, cut it off the roll and place the food inside. Place the bagged item in the vacuum sealer, push the button and watch the air get extracted from the bag and the bag get sealed. Then, simply place the sealed item in the refrigerator or freezer. Using vacuum sealers to preserve cooked and uncooked food for storage makes time in the kitchen fun and efficient.
