Which kind of packing box and lunch box do you use? Start with the most common plastic packaging boxes on the market.

So can the lunch box enter the microwave oven?
It is safe to pack food, but it does not mean that it is safe to heat. Of these plastic packaging boxes, only "5" plastic polypropylene (PP) can enter the microwave oven. Polypropylene (PP) is relatively heat-resistant and can withstand high temperatures of around 200°C. Therefore, it can be heated by microwaves and repeated heating does not cause any major problems. The heat resistance of other plastics is much worse. It is best not to heat directly, or to put too hot food, of course, can not be used repeatedly.
The heat resistance of the PS lunch box can fully meet the requirements. In addition, compared with the current PP on the market, there are paper lunch boxes, etc., because it has better heat insulation, so it has a heat preservation effect on the packaged food.

Any good packaging container, if it is used unreasonably or even destructively, will not be able to protect food or even be harmful.
