Product Description:Compatible with FoodSaver brand and most other brands of vacuum-packaging systems, this set of three 27.9cm -by-4.88m rolls of plastic bagging material allows for creating custom bags for storing average-sized perishable foods that may be oddly shaped, such as pork chops or wedges of cheese. The heavy-duty, nylon-reinforced wrap preserves food's flavour and freshness for up to five times longer than other storage methods when used with a sealing appliance, which means less food wasted. Designed with channels that make air removal more efficient, as well as multi-ply construction that offers a superior barrier against moisture and oxygen, the bags actually prevent freezer-burn. Furthermore, they can be safely used in a microwave or dropped directly into a pot of boiling water to thaw--making home-cooked meals a breeze. A great alternative to flimsy, landfill-clogging zip-top storage bags, the bags can be washed out by hand or in the dishwasher and reused, as long as they have not previously stored raw meats, fish, or greasy foods that could pass along food-borne illnesses.
