Among the materials for food use, polypropylene (PP) can withstand 140°C, followed by polyethylene (PE) which can withstand heat at 110°C, and polystyrene (PS) ) can only withstand heat up to 90°C. Currently commercially available plastic lunch boxes for microwave ovens are mainly made of PP or PE. If the temperature exceeds their heat resistance limit, the plasticizer may be released. Therefore, long-term use of high-temperature heating of plastic tableware to reheat food should be avoided. .
