Microwaving Plastic:

In general, it is best to follow the manufacturer’s recommendations when using any plastic products. When cooking with plastics, only use those plastic containers, wraps, bags and utensils for their intended purposes.

According to the USDA Food Safety and Inspection Service (FSIS), some plastics can be safely used in the microwave, but others should not:

Micowave Safe:
Microwave-safe wraps, heatproof glass, glass-ceramic, oven cooking bags, parchment paper, wax paper, heat-susceptor packaging, and heavy plastic wrap as long as it doesn't touch the food. You can also use cookware that's specifically labeled for microwave use, including some plastics.

Not Micowave Safe:
Plastic storage containers like margarine tubs, takeout containers, and whipped topping bowls can warp or melt in the microwave, which could allow harmful chemicals to get into your food. You should also avoid using thin plastic storage bags, brown paper or plastic grocery bags, newspapers, or aluminum foil in the microwave.

The U.S. Department of Agriculture Food Safety Inspection Service (FSIS) has some helpful guidelines for cooking with plastics in microwave ovens.
