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材質氣泡袋

1、 PA material bubble bag

PA就是(PE+PA，PA材質的氣泡袋承壓強，拉伸性強，可用于重量級產品，大型產品或需加強性保護的產品。一般PA材質的氣泡袋我們都是做成有閥門的，這種氣泡袋可以手動充氣也可以機器自動化充氣。

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材質氣泡袋

2、 Po material bubble bag

PO材質就是HDPE，這種高密度聚乙烯做成的氣泡袋呈乳白色、抗沖擊性強。這種材質的氣泡袋一般會做成無閥門的，充氣的時候需要封口機一邊封口一邊充氣，由于價格相對低廉，緩沖能力明顯，而且可以實現自動化充氣，所以現在很多商家企業發貨都會選擇這種材質的氣泡袋。

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材質氣泡袋

3、 PE Bubble Bag

PE就是LDPE，低密度聚乙烯，這種材料透明、手感柔軟、外觀美觀。材質可以做成有閥門也可以做成無閥門的氣泡袋，這個要看客戶的需要。

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.

根據經驗人士表示，優質的氣泡袋在基本原料選用上，主要系利用優質的PE+PA（尼龍）薄膜，屬于聚乙烯材料。尼龍含量高，延展性好。所用原料安全無毒、可回收、無環保問題。氣泡膜平滑細膩，表面印刷性佳。氣體包裝袋通過ISO 140001標準，符合ROHS規范；劣質的用料通常使用回收雜料，顏色泛黃，暗沉，紋路粗糙，或是降低質量標準等損害消費者的行為。尼龍含量低，用力一擠就爆了。

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.
