FoodSaver 11" Vacuum Seal Rolls let you create custom-sized bags to package and protect food and non-food items using your FoodSaver Vacuum Sealer. Made from the exact same material as our bags, FoodSaver Rolls give you great flexibility. Simply cut a piece to your desired length, seal one end, fill and then vacuum seal. Channels allow complete air removal and multi-layer construction blocks moisture and oxygen and makes the bags strong enough to simmer and microwave. BPA-free.
