With FoodSaver bags and rolls, you can keep your food fresh longer in the kitchen and refrigerator. By removing air and extending shelf life by up to five times, you can keep food fresh in the freezer for months, even years, without the risk of freezer burn. Cheese can be stored in the refrigerator for months, and fresh produce can stay fresh for several weeks. FoodSaver bags and rolls feature a patented design that completely removes air, preventing air pockets from forming around the food. FoodSaver bags are made from a durable 5-layer material with special channels that allow for efficient and complete air removal.
