在我们生活中餐具的种类有很多，例如一次性纸餐盒。那么，这种餐盒可以微波炉加热吗？实际上是不可以的，下面来分析分析。

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.

现在纸包装盒也很流行，比如比萨、汉堡等食品都会用到。纸包装盒现在也很流行，比如比萨、汉堡等食品都会用过的。纸饭盒内侧摸起来很滑，是一层塑料薄膜，叫聚乙烯涂层。这是一个比较新的工艺，在浇铸时纸的表面镀了一层。一层薄薄的聚乙烯塑料涂层相当于覆盖在纸上的一层塑料薄膜。这样纸饭盒不仅可以承受90℃左右的高温，水，包装食物，处理冷热饮料都没有问题。但温度较高的纸饭盒处理不了，所以不建议直接放入微波炉中热的。

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.

因为这种材质的饭盒熔点非常低，经微波炉加热之后，会与食物融化在一起无法食用。同时，也会起化学反应产生有毒物质，例如致癌物，对人体会造成很大的伤害。另外，不仅仅是一次性纸餐盒不能加热，只要是没标能微波加热的容器都不可以。

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.

对于一次性纸餐盒来说，只能用于盛装食物，并且不能二次使用。因为对于这种餐具来说，它基本都是以聚苯乙烯为主要物质的，耐腐蚀非常差，并且还没有抗油脂的能力，所以不建议二次使用，容易滋生细菌。

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.

一次性纸餐盒微波加热后是否有毒，取决于饭盒的具体材质，如果是pp聚丙烯5号塑料饭盒，可以用微波炉加热，并且是安全的。PP（聚丙烯）多用于制作水桶、垃圾桶、篮子、篮子和微波炉的食品容器等。常见的豆浆瓶、酸奶瓶、果汁饮料瓶、微波炉饭盒。它的熔点高达167°C，是可以放入微波炉中并经过仔细清洁后可以重复使用的塑料外壳。请注意，有些微波炉饭盒本体是5号PP，盖子是1号PE。由于PE不能耐高温，因此不能与盒体一起放入微波炉。

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.
