发布日期:2022-09-06 作者:www.jnsuliao.com 点击:

塑料袋应该是我们日常生活中常见到并使用到的一种东西了,当然有的人认为这种塑料袋存在一定的毒性,对人体以及食物等不好就不会用,那么下面济南塑料袋厂家就来分析下它是否有毒性以及优点。
Plastic bags should be a kind of thing we often see and use in our daily life. Of course, some people think that this kind of plastic bag has certain toxicity, and will not be used if it is bad for human body and food. Then the Jinan plastic bag manufacturer will analyze whether it is toxic and its advantages.
塑料袋的毒性鉴别
Toxicity identification of plastic bags
常用的食品塑料袋多为聚乙烯薄膜制成,该薄膜无毒,故可用于盛装食品。还有一种薄膜为聚氯乙烯制成,聚氯乙烯本身也无毒性,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。
Most commonly used food plastic bags are made of polyethylene film, which is non-toxic, so it can be used to hold food. Another kind of film is made of polyvinyl chloride, which is also non-toxic. However, according to the use of the film, the additives added are often harmful to human body and have certain toxicity. Therefore, this kind of film and the plastic bags made of this film are not suitable for containing food. If you want to identify PVC plastic bags and polyethylene plastic bags, you can use the following simple method to identify them.
聚乙烯薄膜(无毒性)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。
Polyethylene film (non-toxic): the film is milky white and translucent (especially obvious when several layers are stacked). It feels lubricating. It seems that the surface is coated with wax layer. It shakes hard, and the sound is brittle. It is flammable in case of fire. The flame is yellow, and there is mucus dripping when burning. It also has the smell of candle burning.

聚氯乙烯薄膜(一般有毒性)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。
PVC film (generally toxic) is transparent if no pigment is added. It feels sticky on the surface, shakes forcefully, and has a low voice. It is difficult to burn in case of fire. It extinguishes immediately after leaving the flame. The flame is green.
