背心袋在我们日常生活中随处可见，很多商家和企业也需要定做背心袋，但是你知道背心袋定做的原料是什么吗？什么样的背心袋是合格的吗？

Vest bags can be seen everywhere in our daily life. Many businesses and enterprises also need to customize vest bags. But do you know what the materials are? What kind of vest bag is qualified?

定做背心袋的原料都有哪些？我们日常生活中常用的背心袋制作原料主要有两种，一是PO（即：HDPE高密聚乙烯）；二是PE（即：LDPE低密聚乙烯），前者(PO）的使用量多余后者（PE）。怎么样区分这两种原料呢？

What are the materials for customized vest bags? There are two kinds of materials commonly used in our daily life to make vest bags. One is PO (i.e. HDPE high-density polyethylene); The second is PE (i.e. LDPE low density polyethylene). The use of the former (PO) is more than that of the latter (PE). How to distinguish these two materials?

PO背心袋的光泽度较低，质感略硬，用手轻晃，能听到哗哗的响声；而PE背心袋的光泽度较好，质感较软，用手轻晃，响声很小。这两种材料都无味，卫生。

The glossiness of PO vest bag is low, the texture is slightly hard, and you can hear the noise when you gently shake it with your hand; The PE vest bag has good glossiness and soft texture. It makes little noise when you shake it with your hand. These two materials are non-toxic, tasteless and sanitary.

除了PE和PO之外，还有就是可降解材料，随着和人民对的重视，以后普通材料的背心袋可能会被可降解材料取代。

In addition to PE and PO, there are also degradable materials. With the national and people's attention to environmental protection, the vest bags made of ordinary materials may be replaced by degradable materials in the future.
