Whether it is safe to microwave food on plastic or not depends on the type of plastic and how it is used.
Microwave-safe plastics marked with symbols are safe for heating food. 2, 4, and 5 are recommended for food storage, avoiding numbers 1, 3, 6, or 7.
To prevent chemical leaching in the microwave, use thicker, sturdier containers instead of damaged or flimsy plastic to prevent warping or melting.
Choose microwave-safe food storage & heating options for greasy or acidic foods, avoid using cracked, scratched, or broken plastic containers.
Glass, ceramic, and silicone are safe and sustainable alternatives for microwaving due to their heat-resistant and non-reactive.
