A microwave-safe plastic plate will retain less heat than a traditional dinner in the microwave. Many people across North America consume TV dinners and use splatter guards in the microwave. If you decide to use a plastic plate in the microwave, I would recommend BPA-free one. Always avoid using Single-use containers in the microwave. If you still have concerns about using plastic dinnerware in the microwave, glass or ceramic is ideal. These options may not be as thermally optimal as plastic, but it’s the next best thing.
