Polyethylene film is the main raw material of food plastic bags. It is widely used to contain food. However, plastic bags made of PVC are toxic. How to identify these two kinds of plastic bags? Here are five simple ways to tell:

1、目测法聚乙烯薄膜呈乳白色、半透明状（几层叠起来观察尤为明显）。而聚氯乙烯薄膜不加色素为透明状，加色素后颜色混浊或呈淡黄色。

1. By visual inspection, the polyethylene film is milky white and translucent (especially when several layers are stacked). The PVC film is transparent without pigment, and the color is turbid or light yellow after adding pigment.

2、抖动法抓住塑料袋用力抖动，的塑料袋声音清脆，而有毒的塑料袋声音闷涩。

2. The shaking method grabs the plastic bag and shakes it hard. The sound of the plastic bag is crisp, while the sound of the toxic plastic bag is dull and astringent.

3、触摸法塑料袋手摸时有润滑感，表面似有蜡，有毒塑料袋则手感发黏。

3. Touch method: the plastic bag has a sense of lubrication when touching, the surface seems to have wax, and the toxic plastic bag feels sticky.

4、漂浮法把塑料袋放入水中，塑料袋可浮出水面，有毒塑料袋浮不上来。

4. The floating method puts the plastic bag into the water, the plastic bag can surface, and the toxic plastic bag can't float up.

5、燃烧法聚乙烯薄膜遇火易燃，火焰呈黄色，燃烧时有黏液滴落，并有似蜡烛燃烧的气味。而聚氯乙烯薄膜遇火不易燃烧，离火即熄，火焰呈绿色。

5. Combustion polyethylene film is flammable in case of fire, and the flame is yellow. During combustion, mucus drops and smells like candle combustion. The PVC film is not easy to burn in case of fire. It goes out immediately after leaving the fire, and the flame is green.
