Consumers should only use plastics for their intended purposes. Always read directions, but generally microwave-safe plastic wraps, wax paper, cooking bags, parchment paper, and white microwave-safe paper towels are safe to use in the microwave. For more complete information regarding the safety of using plastic in the microwave, see the U.S Food and Drug Administration explanation at http://www.fda.gov/fdac/features/2002/602_plastic.html.
