It's two pieces of film that didn't stick well. It's a little difficult to adjust. It doesn't blow and it has rotten bubbles. It needs master's skill

其次就是氣泡膜又稱氣墊膜、汽珠膠，汽泡卷等等,使用低密度 防靜電氣泡卷聚乙烯加工而成，是當前普遍使用的一種透明軟包裝材料,用途廣泛。其原理是以薄膜包含空氣使之形成汽泡來防止產品撞擊，確保產品受到震動時起到保護作用，同時亦有保溫隔熱的作用，適合各行各業的不同產品包裝或周轉之用！由于氣墊膜中間層充滿空氣，所以體輕，富有彈性，具有隔音，防震、防磨損的性能，它防水，防潮，抗壓．

The second is bubble film, also known as air cushion film, bead rubber, bubble roll, etc., which is made of low-density antistatic bubble roll polyethylene. It is a kind of transparent flexible packaging material widely used at present. The principle is that the film contains air to form bubbles to prevent the impact of the product, so as to ensure the protection of the product when it is vibrated. At the same time, it also has the function of thermal insulation, which is suitable for different product packaging or turnover in all walks of life! Because the middle layer of air cushion membrane is full of air, it is light, elastic, sound proof, shockproof and abrasion proof

汽泡袋又分單面和雙面兩種,單面汽泡袋適宜保護自身重量較輕的產品，雙面汽泡袋防震力強適合體積較大較重之物品包裝。單、雙面汽泡袋均適

There are two kinds of bubble bags: one-sided and two-sided. One-sided bubble bag is suitable for protecting products with light weight. Two sided bubble bag has strong shock resistance and is suitable for packaging larger and heavier goods. Single and double side bubble bags are suitable

分全新料和回料兩種，全新料的質量肯定是好些的，但是相對來說成本也會高點，如果你只是郵寄東西包裝下的話，可以選擇用80%左右新料的，這種材質里面只加入了20%回料，質量也是很不錯的，氣泡里的氣很足，緩沖抗壓效果也是很不錯的！這樣你的包裝成本也降低了不少。

There are two kinds of new materials and recycled materials. The quality of the new materials is certainly better, but the cost will be higher relatively. If you just mail things for packaging, you can choose about 80% of the new materials. This kind of material only adds 20% recycled materials. The quality is also very good. There is enough air in the bubbles, and the cushioning and compression effect is also very good! In this way, your packaging cost is also reduced a lot.
