在我們生活中餐具的種類有很多，例如一次性紙餐盒。那么，這種餐盒可以微波爐加熱嗎？實際上是不可以的，下面來分析分析。

There are many kinds of tableware in our life, such as disposable paper lunch boxes. Well, can this kind of lunch box be heated in a microwave oven? In fact, it is not possible. Let's analyze it.

現在紙包裝盒也很流行，比如比薩、漢堡等食品都會用到。紙包裝盒現在也很流行，比如比薩、漢堡等食品都會用過的。紙飯盒內側摸起來很滑，是一層塑料薄膜，叫聚乙烯涂層。這是一個比較新的工藝，在澆鑄時紙的表面鍍了一層。一層薄薄的聚乙烯塑料涂層相當于覆蓋在紙上的一層塑料薄膜。這樣紙飯盒不僅可以承受90℃左右的高溫，水，包裝食物，處理冷熱飲料都沒有問題。但溫度較高的紙飯盒處理不了，所以不建議直接放入微波爐中熱的。

Now paper packaging boxes are also very popular, such as pizza, hamburgers and other foods. Paper packaging boxes are also very popular now, such as pizza, hamburgers and other food will be used. The inside of the paper lunch box feels very slippery. It is a layer of plastic film called polyethylene coating. This is a relatively new process. The surface of the paper is plated during casting. A thin layer of polyethylene plastic coating is equivalent to a layer of plastic film covering the paper. In this way, the paper lunch box can not only withstand the high temperature of about 90 ℃, but also have no problems in water, packaging food and handling hot and cold drinks. However, paper lunch boxes with higher temperature cannot be processed, so it is not recommended to put them directly into the microwave oven for heating.

因為這種材質的飯盒熔點非常低，經微波爐加熱之后，會與食物融化在一起無法食用。同時，也會起化學反應產生有毒物質，例如致癌物，對人體會造成很大的傷害。另外，不僅僅是一次性紙餐盒不能加熱，只要是沒標能微波加熱的容器都不可以。

Because the melting point of the lunch box made of this material is very low, it will melt with food after being heated in the microwave oven and cannot be eaten. At the same time, it will also react chemically to produce toxic substances, such as carcinogens, which will cause great harm to human body. In addition, not only disposable paper lunch boxes can not be heated, but also containers that are not marked with microwave heating can not be heated.

對于一次性紙餐盒來說，只能用于盛裝食物，并且不能二次使用。因為對于這種餐具來說，它基本都是以聚苯乙烯為主要物質的，耐腐蝕非常差，并且還沒有抗油脂的能力，所以不建議二次使用，容易滋生細菌。

For disposable paper lunch boxes, they can only be used to contain food, and can not be reused. For this kind of tableware, polystyrene is the main material, which is very poor in corrosion resistance and has no ability to resist grease. Therefore, it is not recommended to use it again, which is easy to breed bacteria.

一次性紙餐盒微波加熱后是否有毒，取決于飯盒的具體材質，如果是pp聚丙烯5號塑料飯盒，可以用微波爐加熱，并且是安全的。PP（聚丙烯）多用于制作水桶、垃圾桶、籃子、籃子和微波爐的食品容器等。常見的豆漿瓶、酸奶瓶、果汁飲料瓶、微波爐飯盒。它的熔點高達167°C，是可以放入微波爐中并經過仔細清潔后可以重復使用的塑料外殼。請注意，有些微波爐飯盒本體是5號PP，蓋子是1號PE。由于PE不能耐高溫，因此不能與盒體一起放入微波爐。

Whether a disposable lunch box is toxic after microwave heating depends on the specific material of the lunch box. If it is a PP polypropylene No. 5 plastic lunch box, it can be heated in a microwave oven and is safe. PP (polypropylene) is mostly used to make buckets, garbage cans, baskets, baskets and food containers for microwave ovens. Common soymilk bottle, yogurt bottle, fruit juice drink bottle, microwave lunch box. Its melting point is as high as 167 ° C. It is a plastic shell that can be put into a microwave oven and reused after careful cleaning. Please note that some microwave lunch boxes have No. 5 PP body and No. 1 PE cover. Because PE can not bear high temperature, it can not be put into the microwave oven together with the box.
