The functional layer of composite packaging bags mainly plays a role in blocking light, preventing penetration, good heat sealing, transparency, and sunlight opening. Nowadays, there are two ways to make bags. One is that packaging factories fill household rolls of film on automatic packaging machines, and then shape and package them into various packaging bags; In addition, another is the bag making machine that forms various types of packaging.
