The FoodSaver is a vacuum seal machine that seals anything from steak to blueberries inside a plastic bag while removing extra air with an internal vacuum. The result is a compact bag of food that deters mold and bacteria by locking in natural moisture and blocking oxygen. A vacuum-packaged loaf of bread may stay fresh up to five times longer than a twist-tied loaf in your bread box. All 25 models of FoodSaver vacuum sealers share the same basic function of food preservation. Choose a model with features that satisfy your food storage needs.
