FoodSaver 12 Gallon-Size Vacuum Zipper Bags With the FoodSaver brand’s 12-count gallon-size vacuum zipper bags, reliable food storage and peace of mind are at your fingertips. Use the vacuum zipper bags for storing expensive cold cuts, freshly caught fish, garden vegetables, sliced fruit, and more. Whether you’re prepping food for a party, making sandwich fixings easily accessible during the week, or simply keeping healthy snacks on hand, the reusable and resealable bags offer exceptional convenience in the kitchen. Creates an Air-Tight Seal To use, simply add food to the bag–its expandable bottom helps ensure easy filling. Once filled, zip the bag completely shut using the reinforced double-track zipper. Next, place a handheld vacuum sealer (sold separately) over the valve marked within the circle on the bag, and press the button. In one smooth move, the system removes all the air out of the bag, creating a stay-fresh, air-tight seal. Multi-Layer BPA-Free Material The FoodSaver bags feature a unique multi-layer BPA-free material with specially designed channels that allow for the complete removal of air. By removing all of the air inside the bag and creating an air-tight barrier around foods, the durable bag material locks in freshness and effectively prevents stored items from spoiling or getting freezer burned. In addition to blocking moisture and oxygen that can compromise the freshness of food, the bags’ multi-layer construction makes the bags safe and strong enough for freezing, microwaving, and boiling.
