在這個快節(jié)奏的社會，很多人無暇自己做飯。因此，經常吃一次性飯盒的外賣成了一種習慣，偶爾飯菜涼了，必須要用到微波爐加熱。所以，一次性飯盒能不能放到微波爐加熱呢？加熱后食用對身體有沒有害呢？

　　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?

　　總的來說,只要不含金屬材料的器皿都可以放進微波爐加熱。比如一次性餐盒，泡沫塑料，紙品，方便面碗，都是可以加熱的。但是，加熱后是否安全，這個就另當別論了，我們看一下用微博爐加熱應該注意什么呢？

　　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

　　認準「PP」標識

　　Identify the "PP" logo accurately

　　許多外賣商家都喜歡用塑料一次性盒子來打包飯菜，然而不是所有的塑料一次性盒子都可以放到微波爐里加熱的。

　　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.

　　大部分塑料盒上都會有一個三角標識，上面還會標有數字。

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

　　有些人誤以為這里的數字是代表塑料盒可以重復使用幾次：「1」代表只能用一次，「2」代表可以用兩次……

　　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

　　但實際情況并不是這樣的，這里的數字是代表塑料容器的材質。制作材質不同，使用上禁忌上也不同。有的不耐高溫，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

　　而耐高溫、適合微波爐加熱的材質只有一種，那就是聚丙烯（PP），塑料材質辨識碼為「5」，如下圖所示。

　　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，在把外賣放進微波爐里前，一定要查看塑料餐盒上是否有「PP」或三角箭頭上是否標有「5」的標識。

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

　　如果一次性餐盒上沒有相應標識，最好換一個適合微波爐的容器進行加熱。

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

　　當然，即便是可以微波加熱的外賣盒，加熱一次之后也不建議再次使用了。微波加熱和食物中本來的油脂，都會讓包裝盒中一些可能對身體有害的物質加速遷出。并且，外賣盒的材料也相對比較薄和脆，不太適合重復使用。

　　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.

　　紙質一次性餐具

　　Paper disposable tableware

　　注意有無塑料覆蓋膜

　　Pay attention to whether there is a plastic cover film

　　除了塑料一次性餐盒，也有不少餐廳選擇紙質的一次性餐具來打包食物。

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

　　一般來說，質感啞光，沒有塑料膜的這一類包裝盒是可以放進微波爐的。

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

　　這類餐具是用甘蔗渣、秸稈等原料制作，它最大的優(yōu)勢就是安全性高一些，使用的技術比較接近造紙技術。質量比較過關的產品，還可以放進微波爐里加熱。

　　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.

　　但是紙板制作加塑料覆膜這種餐具，盡量不要放進微波爐里加熱。

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

　　我們常見到的紙杯、方便面桶、牛皮紙餐具，都屬于這一類餐具。

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

　　這類餐具內部覆膜所用到的塑料膜大多是 PE 淋膜材質的，隨著環(huán)保意識的增強，使用可降解的 PLA 淋膜餐具的商家也越來越多。但這些覆膜都不耐高溫，不適合放進微波爐加熱。

　　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.

　　除了這類餐具外，有的貼心商家為了防止湯汁外濺，往往會在外賣盒外面包裹一層保鮮膜。

　　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.

　　保險起見，盡量把保鮮膜撕去再進微波爐。因為不清楚商家用的是 PE 聚乙烯保鮮膜，還是 PVC 保鮮膜。PE 可以進微波爐，PVC 則不能（增塑劑會遷出）。

　　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).

　　如果擔心微波加熱時湯汁飛濺，可以自己用包裝上聲明可以進微波爐的保鮮膜包一層，或者用微波遮罩蓋上。

　　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.
