As an "important role" in commodity circulation, packaging must well meet and serve the cushioning and seismic packaging requirements of internal commodities. Nowadays, with the more and more popular of bubble bags, the bubble bags produced in the market have various materials and uneven quality. So, what's the material of the bubble bag? How to distinguish the quality of material?

一、PA材质气泡袋

1、 PA material bubble bag

PA就是(PE+PA，PA材质的气泡袋承压强，拉伸性强，可用于重量级产品，大型产品或需加强性保护的产品。一般PA材质的气泡袋我们都是做成有阀门的，这种气泡袋可以手动充气也可以机器自动化充气。

PA is (PE + PA). The bubble bag made of PA has strong pressure bearing and tensile properties. It can be used for heavy products, large products or products requiring enhanced protection. General PA material bubble bag we are made of valve, this kind of bubble bag can be manually inflated, also can be automatically inflated by machine.

二、PO材质气泡袋

2、 Po material bubble bag

PO材质就是HDPE，这种高密度聚乙烯做成的气泡袋呈乳白色、抗冲击性强。这种材质的气泡袋一般会做成无阀门的，充气的时候需要封口机一边封口一边充气，由于相对低廉，缓冲能力明显，而且可以实现自动化充气，所以现在很多商家企业发货都会选择这种材质的气泡袋。

Po material is HDPE, this kind of high density polyethylene bubble bag is milky white, strong impact resistance. This kind of bubble bag is usually made of valveless material. When it is inflated, it needs a sealing machine to seal and inflate at the same time. Because the price is relatively low, the buffering capacity is obvious, and automatic inflation can be realized, many businesses now choose this kind of bubble bag for delivery.

三、PE材质气泡袋

3、 PE Bubble Bag

PE就是LDPE，低密度聚乙烯，这种材料透明、手感柔软、外观美观。材质可以做成有阀门也可以做成无阀门的气泡袋，这个要看客户的需要。

PE is LDPE, low density polyethylene, this material is transparent, soft, beautiful appearance. The material can be made into bubble bags with or without valves, which depends on the needs of customers.

根据经验人士表示，的气泡袋在基本原料选用上，主要系利用的PE+PA（尼龙）薄膜，属于聚乙烯材料。尼龙含量高，延展性好。所用原料、可回收、无环保问题。气泡膜平滑细腻，表面印刷性佳。气体包装袋通过ISO 140001标准，符合ROHS规范；劣质的用料通常使用回收杂料，颜色泛黄，暗沉，纹路粗糙，或是降低质量标准等损害消费者的行为。尼龙含量低，用力一挤就爆了。

According to experts, the selection of basic raw materials for high-quality bubble bags is mainly made of high-quality PE + PA (nylon) film, which belongs to polyethylene material. High Nylon content and good ductility. The raw materials used are safe, non-toxic, recyclable and environmental friendly. The bubble film is smooth and fine with good surface printability. The gas packaging bag has passed ISO 140001 standard, which conforms to ROHS standard; the inferior materials usually use recycled miscellaneous materials, with yellowing, dark, rough grain, or lower quality standard, which damages consumers. The nylon content is low, and it will explode if you squeeze hard.
