I prefer this form of lamination to the "heat" laminating machines that are sold in craft stores. These sheets can be done to perfection without bubbles, curling, or incomplete seals. I've never seen any project using thermal lamination that could boast near perfection. In my experience, the heat doesn't create a perfectly sealed item. These sheets are IDEAL !
