The Shield N Seal heavy-duty professional-grade vacuum sealer seals packages up to 16 inches wide and features an impact seal mode. This mode ensures that nothing gets pulled into the sealer, a problem with some lower-quality devices produced by other manufacturers. Foods won't be crushed in the sealing process, and the sealer works with bags and rolls up to 16 inches. In addition, a marinate mode guarantees foods come out flavorful and moist, and the powerful seal protects against freezer burn and the mingling of food tastes and odors. The roll holder accommodates a 50-foot roll, and the machine comes with an extra-wide seal bar and a super easy cutter. The sequential timer mode allows for the rapid sealing of similar items.
