You could buy a product that is used to protect floors during construction. It is a plastic that peels off. A cheaper way would be to packing tape, it's 1.88" wide and comes in 40 or 45foot rolls. Just tape the entire back the pull it off. It could be that regular plastic food wrap would work but you would have to try it because as you know sometimes it sticks and sometimes it doesn't but it always sticks to itself.
