Parchment is a much better choice to prevent food sticking. Wax paper should work pretty well too but doesn't deal with heat as well.
Unfortunately, you can not wrap hot food in wax paper. It causes the very light coat of wax on the paper to melt onto the food. It is paraffin was, so it is food safe.
For foil, in the event you don't have the non stick foil, then give the sheet of regular foil a light spray with Spam or like product.
If you are using the plastic wrap for covering bread dough for rising, you should spray that also, so that the dough doesn't stick to it as it rises to the top and touches it.
The moral of the story, when in doubt, spray it.
