Custom make bags according to your needs with the Food Saver Rolls. Simply cut to the desired length and seal one end with your Food Saver appliance-your custom-size bag is ready to go. Food Saver 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 Food Saver Rolls are safe to freeze, simmer or microwave, and are proven to prevent freezer burn better than leading freezer bags.
