1. Is the microwave lunch box healthy?
Recently, the Consumer Council of Hong Kong released an investigation report that nearly 30% of plastic lunch boxes that can be heated by microwave will release plasticizers, including some big brands of microwave lunch boxes, such as Lock &；; Locking. Most of us think that microwave lunch boxes are specially designed for microwave ovens, so we all think that microwave lunch boxes should not release plasticizers when heated in microwave ovens. Not only consumers think so, but also many box lunch salesmen don't know about it. Here, I would also like to add that the microwave lunch box actually has a shelf life, and it will be risky to use it beyond the time limit.
Some unqualified microwave lunch boxes will release four plasticizer components, namely DBP, DEHP, DINP and DIDP, when heated in the microwave oven, with the content ranging from 0.05 mg/kg to 5 mg/kg. If the quality is worse, the lid will change color.
Plasticizers can enhance the flexibility of plastics and are widely used in industry. At present, polypropylene (PP) can withstand 140℃, while polystyrene (PS) can only withstand 90℃. At present, the plastic lunch boxes of microwave ovens mainly use polypropylene and polyethylene, which can withstand the high temperature of 100 degrees. But once the temperature exceeds this temperature, the plasticizer may be released, so it is necessary to avoid heating food at high temperature for a long time.
Plasticizers can interfere with the endocrine system of human body. Long-term intake of plasticizer will damage liver and kidney and affect development and growth. For men, plasticizers can also have an impact on the reproductive system. However, the content of plasticizer in general microwave lunch boxes is lower than the European standard EU10/1,which is still harmless to people's health, so consumers need not worry too much. But be careful after heating.

My conclusion: the lunch box in the microwave oven is safe without being heated in the microwave oven, and it is not harmful to people's health. However, some lunch boxes will release plasticizers and other substances harmful to human health after heating. But there are still many microwave lunch boxes that are safe after reheating, so pay special attention when buying them.
