　　关于塑料袋的相关介绍：

Introduction to plastic bags:

　　常用的食品塑料袋多为聚乙烯薄膜制成，该薄膜，故可用于盛装食品。还有一种薄膜为聚氯乙烯制成，聚氯乙烯本身也性，但根据薄膜的用途所加入的添加剂往往是对人体有害的物质，具有一定的毒性。所以这类薄膜及由该薄膜做的塑料袋均不宜用来盛装食品。如要鉴别聚氯乙烯塑料袋和聚乙烯塑料袋，可用下面简易法进行辨认。

The commonly used food plastic bags are mostly made of polyethylene film, which is non-toxic and can be used to hold food. There is also a type of film made of polyvinyl chloride, which itself is non-toxic, but the additives added according to the purpose of the film are often harmful substances to the human body and have a certain degree of toxicity. So this type of film and plastic bags made from it are not suitable for containing food. To distinguish between polyvinyl chloride plastic bags and polyethylene plastic bags, the following simple method can be used for identification.

　　聚乙烯薄膜（性）

Polyethylene film (non-toxic)

　　薄膜呈乳白色，半透明状（几层叠起来观察尤其明显），摸起来较润滑，好像表面上涂有蜡层，用力抖动，声音发脆，遇火易燃，火焰黄色，燃烧时有粘液滴落，并有蜡烛燃烧时的气味。

The film is milky white and semi transparent (especially noticeable when stacked several times). It feels relatively smooth to the touch, as if there is a wax layer on the surface. When shaken vigorously, the sound becomes brittle, and it is flammable when exposed to fire. The flame is yellow, and there are droplets of mucus during combustion, as well as the smell of candles burning.

　　聚氯乙烯薄膜（一般有毒性）

Polyvinyl chloride film (generally toxic)

　　如不加色素，为透明状，摸起来其表面有些发粘，用力抖动，声音低沉，遇火不易燃烧，离火焰即熄，火焰呈绿色。

If not colored, it is transparent and feels a bit sticky to the touch. Shake vigorously and the sound is low. It is not easy to burn when exposed to fire and extinguishes immediately after leaving the flame. The flame appears green.
