Ignition Temperature Of Plastic
There are oven-tempered plastic wraps in your grocery store. Read the box for the correct cooking temperature.
The plastic will melt at a lower temperature than it will burn, so you shouldn't worry. What you should worry about is your reason for putting plastic in an oven. Different plastics have different melting and ignition temperatures, can you be more specific?
