This Pacum Sous Vide Food Bag is a multipurpose bag. Use it as a sous vide cooking bag. Sous Vide is a luxurious French cooking technique. You place food in a bag and then use warm water for cooking it masterfully. These bags are small and durable enough to cook your food. It works as a reusable food storage bag too. Insert your food in the bag, put Pacum on the air valve, and then wait a minute. All the air is removed without wasting your time. One of the little-known benefits of vacuum packing is that it keeps bacteria out, as they don’t have the oxygen they need to survive. This is on top of keeping out water spills, odors from other foods, and anything else.
