Release foil allows you to use aluminum foil on barbecue ribs or sticky cinnamon rolls or other food items that would "stick" to regular foil. I think this is a good fix for that problem. The foil has one side (the shiny side) that works like regular foil and then a dull side that is designed to "release" sticky messes. This foil is useful if you, for example, bake ribs or chicken in your oven covered with barbecue sauce. If you use regular foil, the baked on bbq sauce can act like glue and make it hard to scoop up the meat. You can end up with small pieces of foil sticking to the meat and that is very unappetizing. With the release foll, the foil is a mess, but you can easily remove the food from the foil without the foil getting into the food. It is a good name because the foil does "release" the food --unlike regular foil. I like to have this foil on hand for those instances when sticking can be problematic, but I use regular foil if I'm not worried about anything sticking.
