The air column bag, as a buffer package expected in recent years, has good protection, environmental protection and convenient transportation.At present, it has been loved by manufacturers and consumer.When choosing our air column bag, many customers will ask a question, which is equal to the way our air column bag is made, why does the air column bag not leak when inflated?  

                                                                                                                                                                                                                                                                     What is the manufacturing principle and technology?Below, I will break down these mysteries one by one:

Air coiumn bag manufacturing technology: 

1: The air column bag is made of PA PE nylon co-extruded composite material, which is different from the seven-layer film used in commercial places. The air column bag is selected from the high nine-layer co-extruded film in the current industry. It is made by heat sealing with an air cushion bag making machine. The nylon content determines the ductility and compressibility of the air column bag.

2: The air valve of the air column bag adopts the most advanced physical reversing valve in the packaging industry today. The differential pressure of the air is used to lock the valve securely so that air cannot flow out through the valve. The specific reason is the use of air pressure to firmly compress the two diaphragms of the valve. Therefore, the air column bag does not easily leak.
