The Fresh & Save vacuum bags are designed to work with the vacuum pump to keep food fresh up to five times longer than non-vacuum storage. Available in small, medium, and large individually or in handy sets, these bags hold a variety of portion sizes. Freeze whole dinners, reheat lunch for one, or package up fresh ingredients. The easy-zip closure ensures a tight seal and no spills, and the included liquid barrier helps to ensure liquids aren't absorbed by the vacuum pump.
