Right now on Amazon, you can get this 2 Pack of Vacuum Sealer Bags 50′ Rolls for Only $9.99! Simply add food to the bag, insert the open end in a heat-seal vacuum sealing system, and the machine takes care of the rest: removing all the air before creating an airtight seal. By using your vacuum sealing system, water can’t permeate through the bag and mess with your ingredients, so your food stays secure during its water bath. Our bags also resist punctures and tearing. Using bags and vacuum sealers means the pouches are completely airtight, which delivers consistent cooking results and prevents floating during the sous vide water bath.
