　　關(guān)于塑料袋的相關(guān)介紹：

Introduction to plastic bags:

　　常用的食品塑料袋多為聚乙烯薄膜制成，該薄膜，故可用于盛裝食品。還有一種薄膜為聚氯乙烯制成，聚氯乙烯本身也性，但根據(jù)薄膜的用途所加入的添加劑往往是對人體有害的物質(zhì)，具有一定的毒性。所以這類薄膜及由該薄膜做的塑料袋均不宜用來盛裝食品。如要鑒別聚氯乙烯塑料袋和聚乙烯塑料袋，可用下面簡易法進行辨認(rèn)。

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，半透明狀（幾層疊起來觀察尤其明顯），摸起來較潤滑，好像表面上涂有蠟層，用力抖動，聲音發(fā)脆，遇火易燃，火焰黃色，燃燒時有粘液滴落，并有蠟燭燃燒時的氣味。

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，為透明狀，摸起來其表面有些發(fā)粘，用力抖動，聲音低沉，遇火不易燃燒，離火焰即熄，火焰呈綠色。

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.
