That would be mylar or something similar. I have gotten a roll at a local art supply house and used it for certain layups. There are construction techniques that involve doing layups on the mylar sheet and then leaving it on until the epoxy has cured. It will leave a very smooth surface. Alex Strojnik has written at least one book on the method of making wing skins that way.
