This happens automatically. Put the roll in at the top and pull out the required amount and there is a cutter. The vacuum sucks in the bag, seals it and releases it again after sealing. This is the lightest sealer I've ever used. He is also the most reliable. I use it almost every day to seal everything from fresh food to leftovers. I also use sealant to protect important documents. After several families lost their documents during the flood and hurricane, I sealed our birth certificates, passports, and other important papers in plastic and placed them in a safe. Social Security cards can't be laminated, but there's nothing stopping you from vacuum sealing them to protect the paper and then breaking the seal if you need to remove the card for an employer. Hurricane Harvey destroyed the photos and documents of so many important people that vacuum sealing seems the best way to protect these precious items.
