Plastic bags are more common in our days, providing more rapid use. They are more commonly used in supermarkets and major business malls. From the current plastic products circulating in shopping malls, they are generally processed from polyethylene film. In addition, another kind is processed from polyvinyl chloride. We should know some basic common sense when using them in the day. Here, the plastic bag manufacturer briefly introduces the basic skills of using differences in daily life.

塑料袋生產廠家指出塑料袋的分類主要便是聚乙烯以及聚氯乙烯，在區別的時分可以注意兩種物質自身的特性來看。

Plastic bag manufacturers pointed out that the main classification of plastic bags is polyethylene and polyvinyl chloride. When distinguishing, we can pay attention to the characteristics of the two substances.

聚乙烯薄膜是沒有毒性的，呈現乳白色的半透明狀況，假如底層疊加起來看的話會愈加明顯。聚乙烯是比較光滑的，表層看上好像是有蠟層，假如顫動袋子的話，還可以聽到洪亮的聲響。這種資料遇到火會呈現黃色，產生一種蠟燭燃燒后的味道。

Polyethylene film is non-toxic, showing a milky translucent state, which will be more obvious if the bottom layer is superimposed. Polyethylene is relatively smooth. The surface seems to have a wax layer. If the bag vibrates, you can hear a loud sound. This kind of information will appear yellow when encountering fire, producing a smell after candle burning.

聚氯乙烯是受歡迎的合成資料，假如沒有添加色素的話，一般都是透明狀，假如用手觸摸的話會感覺到外表磨砂的。一般假如顫動袋子，這種資料的聲響是比較低沉的，而且一般不容易燃燒，即使短暫的有火焰，也是呈現綠色。這兩種資料的區別相對來說其實是比較簡單的，通過這些都是可以快速辨認。

PVC is a popular synthetic material. If no pigment is added, it is generally transparent. If you touch it by hand, you will feel the frosted appearance. Generally, if the bag vibrates, the sound of this material is relatively low, and it is generally not easy to burn. Even if there is a short flame, it is also green. The difference between the two materials is relatively simple, which can be quickly identified.

塑料袋的運用現在正在減少，為更好的環保日子提倡塑料袋生產廠家運用其他資料來代替，不過即使如此，其作為咱們便當日子的挑選，依然有著非常重要的定位。

The use of plastic bags is decreasing now. In order to better protect the environment, plastic bag manufacturers are encouraged to use other materials to replace them. However, even so, it still has a very important positioning as the selection of our convenient days.
