How to Vacuum Seal Mylar Bags and Extend the Shelf Life of Your Food
To vacuum seal Mylar bags, place the items you want to seal inside the bag, leaving some space at the top. Place the opening of the Mylar bag into a vacuum sealer, and then turn it on, and wait as the air is sucked out of the bag. Once all the air is removed, the sealer will automatically seal the bag, and your items will be vacuum-sealed.
