在这个快节奏的社会，很多人无暇自己做饭。因此，经常吃一次性饭盒的外卖成了一种习惯，偶尔饭菜凉了，必须要用到微波炉加热。所以，一次性饭盒能不能放到微波炉加热呢？加热后食用对身体有没有害呢？

　　In this fast-paced society, many people have no time to cook for themselves. Therefore, eating disposable lunch boxes for takeout has become a habit, and occasionally when the food gets cold, it must be heated in a microwave. So, can disposable lunch boxes be heated in the microwave? Is consuming after heating harmful to the body?

　　总的来说,只要不含金属材料的器皿都可以放进微波炉加热。比如一次性餐盒，泡沫塑料，纸品，方便面碗，都是可以加热的。但是，加热后是否安全，这个就另当别论了，我们看一下用微博炉加热应该注意什么呢？

　　In general, any container that does not contain metal materials can be heated in a microwave oven. For example, disposable lunch boxes, foam plastics, paper products, instant noodles bowls can be heated. However, whether it is safe after heating is another matter. Let's take a look at what to pay attention to when heating with a Weibo stove?

　　塑料一次性餐具

　　Plastic disposable tableware

　　认准「PP」标识

　　Identify the "PP" logo accurately

　　许多外卖商家都喜欢用塑料一次性盒子来打包饭菜，然而不是所有的塑料一次性盒子都可以放到微波炉里加热的。

　　Many food delivery businesses prefer to use disposable plastic boxes to package their meals, but not all disposable plastic boxes can be heated in a microwave.

　　大部分塑料盒上都会有一个三角标识，上面还会标有数字。

　　Most plastic boxes will have a triangular logo with numbers on it.

　　有些人误以为这里的数字是代表塑料盒可以重复使用几次：「1」代表只能用一次，「2」代表可以用两次……

　　Some people mistakenly believe that the numbers here represent how many times the plastic box can be reused: "1" means it can only be used once, "2" means it can be used twice

　　但实际情况并不是这样的，这里的数字是代表塑料容器的材质。制作材质不同，使用上禁忌上也不同。有的不耐高温，有的不易清洗……

　　But the actual situation is not like that, the numbers here represent the material of the plastic container. The production materials are different, and the taboos for use are also different. Some are not resistant to high temperatures, some are difficult to clean

　　而耐高温、适合微波炉加热的材质只有一种，那就是聚丙烯（PP），塑料材质辨识码为「5」，如下图所示。

　　There is only one material that is resistant to high temperatures and suitable for microwave heating, which is polypropylene (PP). The plastic material identification code is "5", as shown in the following figure.

　　所以，在把外卖放进微波炉里前，一定要查看塑料餐盒上是否有「PP」或三角箭头上是否标有「5」的标识。

　　So, before putting takeout in the microwave, be sure to check if there is a "PP" or "5" symbol on the plastic lunch box.

　　如果一次性餐盒上没有相应标识，最好换一个适合微波炉的容器进行加热。

　　If there is no corresponding label on the disposable meal box, it is best to replace it with a container suitable for microwave heating.

　　当然，即便是可以微波加热的外卖盒，加热一次之后也不建议再次使用了。微波加热和食物中本来的油脂，都会让包装盒中一些可能对身体有害的物质加速迁出。并且，外卖盒的材料也相对比较薄和脆，不太适合重复使用。

　　Of course, even takeaway boxes that can be microwave heated are not recommended for reuse after being heated once. Microwave heating and the inherent oils and fats in food can accelerate the migration of some potentially harmful substances from packaging boxes. Moreover, the material of the takeaway box is relatively thin and brittle, making it less suitable for repeated use.

　　纸质一次性餐具

　　Paper disposable tableware

　　注意有无塑料覆盖膜

　　Pay attention to whether there is a plastic cover film

　　除了塑料一次性餐盒，也有不少餐厅选择纸质的一次性餐具来打包食物。

　　In addition to plastic disposable meal boxes, many restaurants also choose paper disposable tableware to pack food.

　　一般来说，质感哑光，没有塑料膜的这一类包装盒是可以放进微波炉的。

　　Generally speaking, packaging boxes with a matte texture and no plastic film can be placed in a microwave oven.

　　这类餐具是用甘蔗渣、秸秆等原料制作，它最大的优势就是安全性高一些，使用的技术比较接近造纸技术。质量比较过关的产品，还可以放进微波炉里加热。

　　This type of tableware is made from raw materials such as sugarcane bagasse and straw, and its biggest advantage is higher safety. The technology used is relatively similar to papermaking technology. Products with relatively good quality can also be heated in a microwave oven.

　　但是纸板制作加塑料覆膜这种餐具，尽量不要放进微波炉里加热。

　　However, tableware made of cardboard with plastic film should not be heated in the microwave as much as possible.

　　我们常见到的纸杯、方便面桶、牛皮纸餐具，都属于这一类餐具。

　　The paper cups, instant noodle buckets, and kraft paper tableware that we commonly see belong to this category of tableware.

　　这类餐具内部覆膜所用到的塑料膜大多是 PE 淋膜材质的，随着环保意识的增强，使用可降解的 PLA 淋膜餐具的商家也越来越多。但这些覆膜都不耐高温，不适合放进微波炉加热。

　　The plastic film used for the internal lamination of these tableware is mostly made of PE film material. With the increasing awareness of environmental protection, more and more businesses are using biodegradable PLA film coated tableware. But these films are not resistant to high temperatures and are not suitable for microwave heating.

　　除了这类餐具外，有的贴心商家为了防止汤汁外溅，往往会在外卖盒外面包裹一层保鲜膜。

　　In addition to these types of tableware, some thoughtful merchants often wrap a layer of plastic wrap around their takeaway boxes to prevent soup from splashing out.

　　保险起见，尽量把保鲜膜撕去再进微波炉。因为不清楚商家用的是 PE 聚乙烯保鲜膜，还是 PVC 保鲜膜。PE 可以进微波炉，PVC 则不能（增塑剂会迁出）。

　　For safety reasons, try to tear off the plastic wrap before putting it into the microwave. Because it is unclear whether the merchant is using PE polyethylene cling film or PVC cling film. PE can enter the microwave oven, while PVC cannot (plasticizers will migrate out).

　　如果担心微波加热时汤汁飞溅，可以自己用包装上声明可以进微波炉的保鲜膜包一层，或者用微波遮罩盖上。

　　If you are worried about splashing soup during microwave heating, you can wrap it with plastic wrap that says it can be microwave heated, or cover it with a microwave mask.
