Each plastic has its heat-resistance limit. In plastics for food use, the most heat-resistant is that polypropylene (pp) can withstand 140 ° C, and secondly, polyethylene (pe) can withstand heat of 110 ° C, while polystyrene Ethylene (ps) can only be heat resistant to 90 °C. At present, the commercially available plastic lunch boxes for microwave ovens are mainly made of pp or pe. If the temperature exceeds their heat resistance limit, there is a possibility of releasing plasticizers, so long-term heating of plastic lunch boxes with high temperature should be avoided. What are the hazards of plasticizers on the human body? According to the survey, plasticizers can interfere with the body's endocrine system and affect the reproductive system of the human body, especially men. Animal studies have shown that long-term intake of plasticizers may damage the liver, kidneys and affect growth.

If the lost part is not well, it will be eaten into the stomach." Don't believe it. Therefore, consumers must pay attention to the shelf life of plastic products. At the same time, aged plastics can release substances harmful to the human body.
