1、一次性外卖打包盒分多钟材质，打包盒上有三角箭头标识且框内数字为5的PP材质的塑料打包盒可用于微波炉加热。其他的塑料打包盒都不可以放到微波炉加热。另外泡沫、纸质材质的打包盒也不能用微波炉加热，用玻璃打包盒加热时，加热时间好不要过久。

1. The disposable takeaway packaging box is made of multiple materials, and the plastic packaging box made of PP material with a triangular arrow mark and a number of 5 in the box can be used for microwave heating. Other plastic packaging boxes cannot be heated in the microwave. In addition, packaging boxes made of foam and paper materials cannot be heated by microwave oven. When heating with glass packaging boxes, the heating time should not be too long.

2、塑料材质主要分为七种，主要根据塑料物质上三角箭头里的数字来分辨，以下做具体介绍：

2. There are mainly seven types of plastic materials, which are distinguished by the numbers in the triangular arrows on the plastic material. The following is a specific introduction:

（1）三角箭头内数字为1的塑料为PET材质，纯净水瓶子以及各种饮料瓶子便是这类材质。这类材质不能放入微波炉中加热，瓶身会在高温作用萎缩，且产生有害的化学成分。

(1) The plastic with the number 1 in the triangle arrow is made of PET material, and pure water bottles and various beverage bottles are of this type. This type of material cannot be heated in a microwave, as the bottle body will shrink under high temperature and produce harmful chemical components.

（2）三角箭头内数字为2的塑料为HDPE材质，装药物、沐浴露、洗洁精的瓶子便是这类材质。不建议循环使用，更不能加热，里面含有非常多的化学成分，容易在高温作用下产生化学反应。

(2) The plastic with the number 2 in the triangle arrow is made of HDPE, and the bottles containing medicine, bath gel and Dishwashing liquid are made of this kind of material. It is not recommended to recycle, let alone heat, as it contains a lot of chemical components and is prone to chemical reactions under high temperatures.

（3）三角箭头内数字为3的塑料为PVC材质，PVC耐热度不高，在高温条件下，容易产生有毒、有害的成分，因此不能放入微波炉中加热。

(3) The plastic with the number 3 in the triangle arrow is made of PVC material, which has low heat resistance and is prone to producing toxic and harmful components under high temperature conditions. Therefore, it cannot be heated in a microwave oven.

（4）三角箭头内数字为4的塑料LDPE材质，这类材质一般用于制作保鲜膜，耐热性较差，放入微波炉中加热容易产生有害物质，人体食用后会有一定损伤。

(4) The plastic LDPE material with a number of 4 in the triangle arrow is generally used for making cling films, but its heat resistance is poor. Heating it in a microwave oven can easily produce harmful substances, which can cause certain damage to the human body after consumption.

（5）三角箭头内数字为5的塑料为PP材质，耐热性较强，放入微波炉中加热不易产生化学反应，因此是可以放心放入微波炉中加热的。

(5) The plastic with the number 5 in the triangle arrow is made of PP material, which has strong heat resistance and is not prone to chemical reactions when heated in a microwave oven. Therefore, it can be safely heated in a microwave oven.

（6）三角箭头内数字为6的塑料为PS材质，这类材质不能在高温条件加热，否则会产生有毒、有害的化学成分，还容易形成聚苯乙烯，可能会影响身体健康。

(6) The plastic with the number 6 in the triangle arrow is made of PS material. This type of material cannot be heated under high temperature conditions, as it will produce toxic and harmful chemical components, and can easily form polystyrene, which may affect physical health.

（7）三角箭头内数字为7的塑料为PC材质，多用于制造奶瓶、太空杯等，内含多酚A，加热后可能会与其他物质发生反应，产生对人体有害的物质。

(7) The plastic with a number of 7 in the triangle arrow is made of PC material and is commonly used in the manufacturing of baby bottles, space cups, etc. It contains polyphenol A. After heating, it may react with other substances and produce harmful substances to the human body.
