Whether a takeaway box can be microwaved depends on the material it is made from. There are 3 main materials used in the common boxes on the market, which are No.1, No.5, No.6 and hydrogenated polypropylene boxes.

Specific as follows:

1, No. 1 polyethylene terephthalate (PET): mineral water, fruit juice, carbonated beverages, plastic bottles are made of it;?

2, No. 5 polypropylene (PP): the best heat-resistant, microwave-heated plastic appliances are commonly used to it;?

3, No. 6 polystyrene (PS): now a lot of milk tea cup cover with it With these materials, plastic lunch boxes packaged food, generally speaking, are safe. Packing food is safe, but that doesn't mean it's safe to heat it up. In these plastic packing boxes, only No. 5 plastic polypropylene (PP) can go into the microwave.

4, hydrogenated polypropylene box is more heat-resistant, can withstand high temperatures of about 200 ℃, so you can microwave heating, repeated heating will not be a big problem. While other plastics are much less heat resistant, it is best not to directly heat, and do not load too hot food, of course, can not be used repeatedly.

The use of microwave heating need to pay attention to the following matters:

1, the microwave oven should be placed in a balanced, ventilated place, the rear should be no less than 10 centimeters and the top of the space of no less than 5 centimeters, in order to facilitate the exhaust heat dissipation and to be far away from household appliances with a magnetic field, in order to avoid affecting the cooking effect.

2, microwave oven food do not put too full, to not more than 1/3 of the volume as well. Food should also not be placed directly on the turntable, to use heat-resistant glass, ceramic or heat-resistant plastic made of containers. Never use metal or enameled containers, or containers with metal patterns.

3, is strictly prohibited to microwave heating sealed food, such as bags, bottles, cans of food, as well as with the skin, shell food, such as chestnuts, eggs, etc., so as to avoid the explosion of contamination or damage to the microwave oven.?

4, the microwave oven is strictly prohibited to use the empty load, usually in the furnace can be prepared a cup of water (glass), out of the use, after heating the food and then put it in, so as not to burn the microwave oven empty load.

5, due to the limited microwave air power, the volume of food is too large, it should be uniformly decomposed, so as to avoid unevenly cooked food. Heating the whole chicken and duck and other large pieces of food, it is best to heat for a period of time, the food will be turned over, so that all parts can be evenly heated.
