In our daily life, we have to deal with all kinds of plastic bags almost every day. What should we pay attention to when using plastic bags?

1、不能放食物的塑料袋坚决不要装食物，只能用来装建筑材料或垃圾的；

1. Plastic bags that cannot hold food must not contain food. They can only be used to contain construction materials or garbage;

2、用来装服装的自封袋或塑料袋，也不要用来装食物；

2. Self sealing bags or plastic bags for clothes, and don't use them for food;

3、可勉强用来盛放食品的自封袋，不要用来装热食。

3. A self sealing bag that can be reluctantly used to hold food, not hot food.

以上三种塑料袋或自封袋都含“毒性”，如聚氯乙烯塑料就是有毒的品种，其原材料是没毒性的，但在制作塑料胶袋过程中加入了有毒的苯、烯料等物质。颜色特别深的塑料袋，如黑色、红色和深蓝色的都是用回收的废旧塑料制品重新加工而成的，对人体有巨大的危害，因此不能用来装入食品。

The above three kinds of plastic bags or self sealing bags contain "toxicity". For example, PVC plastic is a toxic variety, and its raw materials are non-toxic, but toxic substances such as benzene and olefin materials are added in the process of making plastic bags. Plastic bags with particularly dark colors, such as black, red and dark blue, are reprocessed from recycled waste plastic products, which do great harm to human body, so they can not be used for food.

有些商家专用废弃的塑料袋和塑料制品在加工做成塑料袋或自封袋，这些废弃塑料的主要成分是聚氯乙烯，在加工过程中若与不符合国家规定或严重超标的劣质添加剂结合，会产生很强的致癌物。用这样的塑料袋来包装食品、瓜果蔬菜，有害物就会吸附在食物上，即使冲洗也难以除去，对健康危害非常。

Some special waste plastic bags and plastic products are processed into plastic bags or self sealing bags. The main component of these waste plastics is polyvinyl chloride. If they are combined with inferior additives that do not meet national regulations or seriously exceed the standard, they will produce strong carcinogens. When such plastic bags are used to package food, fruits and vegetables, harmful substances will be adsorbed on the food, which is difficult to remove even if washed, which is very harmful to health.

如果用聚氯乙烯塑料袋自封袋盛装超过50℃～60℃的食品，袋中的铅会溶入食品中，塑料袋还会释放有毒气体，侵入到食品当中。人体长期摄入会严重损害身体健康，导致疾缠身。尤其是热的食品装入塑胶自封袋，高温会使塑料中的有毒物质被食物吸收，一旦进入人体就会造成积蓄性中毒，所以装热食品时不可乱用塑料袋。

If the PVC plastic bag is used to contain food with temperature above 50 ℃ ~ 60 ℃, the lead in the bag will dissolve into the food, and the plastic bag will release toxic gas and invade into the food. Long term human intake will seriously damage health and lead to illness. In particular, when hot food is put into plastic self sealing bags, the high temperature will make the toxic substances in the plastic absorbed by the food. Once they enter the human body, they will cause cumulative poisoning. Therefore, do not use plastic bags indiscriminately when loading hot food.
