3. Low density polyethylene (LDPE) fresh-keeping film is mainly used to make the inner film of milk boxes and packaging boxes, because it has water-proof performance, but the heat insulation effect is poor, and it will melt when the temperature exceeds 120 ° C. It is better not to heat it. During daily use, it is best to take off the fresh-keeping film, and do not use it in the microwave oven, otherwise harmful substances will be dissolved.

4. Polypropylene (PP), with good transparency, is mostly used to make disposable boxes in hotels. Of course, the plastic boxes made of it can also be put into the microwave oven for heating. This material is the only plastic box that can be microwaved. When you buy, you must see clearly the polypropylene material and the words "microwaved" on the box.

5. Polystyrene (PS), which is heat-resistant and cold resistant, is mainly used to make fast food boxes and instant noodle boxes. However, it is not suitable to put it into the microwave rate for heating, because too high temperature will release harmful substances. In addition, try not to use it to pack hot food and do not use it to serve strong acid food.
