FoodSaver Rolls have all the same great features as FoodSaver Bags, plus one—rolls allow you to make custom-size bags so you can always have just the right size bag on hand. Most FoodSaver users like to keep both bags and rolls handy for the greatest packaging convenience and flexibility. With FoodSaver Rolls, you always get exactly the size you need. Simply cut to the desired length and seal one end with your FoodSaver appliance—your custom-size bag is ready to go. FoodSaver Rolls come in two widths: 8" and 11". Just like the ready-made FoodSaver Bags, FoodSaver Rolls are made of patented, heavy-duty 5-ply material with special channels that enable the efficient and complete removal of air so none is left trapped in “pockets” around the food. Their construction makes them an especially effective barrier to oxygen and moisture. Bags made from FoodSaver Rolls are safe to freeze, simmer or microwave, and are proven to prevent freezer burn better than leading freezer bags.
