We purchased a couple of sheets of that black plastic looking stuff from a country market.Fantastic to use on the hotplate or grill when you may need to use a dodgy c/park BBQ,just wipe it and roll it up till next time.

We got some sandwich bags made of the black teflon stuff too. I used to use them to toast my sandwiches in the toaster at work. You get some funny looks when you put a cheese and pickle sandwich complete with bag in a normal toaster though.
