2 Rolls 20cm x 6.7m of FoodSaver. Rolls help you keep food fresher for longer in the refrigerator, freezer or cupboards. By removing air and prolonging food freshness for up to five times longer, your meals will stay fresh in the freezer for months, even years—without freezer burn. Cheese keeps in the refrigerator for months and fresh produce can last for weeks. 5 approved layers that prevent air from entering the bag, guaranteeing vacuum packaging. FoodSaver™ Bags and Rolls are made with a patented, high-resistance 5-layer material, with special channels that allow efficient and complete air removal, so that no air is trapped in “bags” around the food. Their design makes them a particularly effective barrier against oxygen and moisture. Pre-made bags, as well as those made from rolls, can be frozen, boiled, or microwaved, and have been shown to prevent freezer burn better than mainstream freezer bags. Suitable for refrigerator, freezer, microwave and cooking.
