What kind of plastics are used in microwave?

Microwavable plastics typically include polypropylene (PP), which has a high melting point and is resistant to heat, and polyethylene (PE), specifically low-density polyethylene (LDPE) for some containers. These plastics are designed to withstand microwave temperatures without melting or releasing harmful chemicals. It's important to check for microwave-safe labels on containers, as not all plastics are suitable for microwave use. Avoid using plastics like polyvinyl chloride (PVC) or polystyrene (PS) in the microwave, as they can warp or leach harmful substances.
