These FoodSaver FSB4802-I vacuum storage bags are designed to work with FoodSaver sealing systems to keep your ingredients fresh up to five times longer than traditional storage methods. Measuring 20.7 cm by 29.2 cm, each transparent bag features impressed air ducts that allow the vacuum sealer to remove air efficiently, which helps protect your food from freezer burn. The rip-proof material is versatile enough for various cooking and storage needs, as it is safe for use in the refrigerator, freezer, microwave, and even boiling water for sous-vide preparation. You can easily organize your pantry using the dedicated labeling space on the bags, and since they are washable, you can reuse them to reduce waste.
