The bubble bag is formed by the way that the film contains air, so as to prevent the impact of the product and ensure the protection of the product when it is vibrated. At the same time, it also has the function of thermal insulation. The manufacturing process of bubble bag is very helpful for our packaging. In the process of production, the middle layer of bubble on the surface of bubble bag is full of air, so it is light, elastic, sound insulation, shockproof and wear-resistant. It is waterproof, moisture-proof and compression resistant, which is very helpful for reducing vibration. In the process of bubble bag production, we should also pay attention to the selection of materials, try to choose some materials that can withstand high temperature, so as to better guarantee the safety of product packaging.
