From a professional point of view, if an enterprise user has certain conditions, you can look at its actual thickness, the flame color after combustion, or pass a series of tests identified by the quality inspection department of the enterprise to determine the quality of the buffer bubble bag.
However, these methods are still lack of operability for ordinary people. Next, there are some methods that individuals can try. First, we can check the appearance and color of the air. For the buffer bubble bag, its material is mostly a mixture of nylon and PEC, and it is also made of ledp. The first-class buffer bubble bag will not add any recycled miscellaneous materials or filling masterbatch. It is thick and not light. It can exude a light pearl shell color in the sun. It looks very comfortable.
If there is a yellowing or dark color, such an air bag is likely to be mixed with recycled old materials. Secondly, you can feel the texture of the buffer bubble bag by hand. The high-quality bubble bag is smooth and delicate without particle feeling; However, due to the impure composition of miscellaneous materials, the hot melt of waste film is uneven. If you touch it carefully with your fingers, you will feel a slight sense of particles. After, we can observe the workmanship of the buffer bubble bag. The high-quality cushion bubble bag is often atmospheric, beautiful and meticulous.
On the contrary, if the air column bag is of poor quality, the work is often poor. Usually, they will press heavy and light at the same time, the bottom seal is not aligned, the grain is rough, and even have serious problems such as fast air leakage and slow air leakage caused by weak pressure.
