Therefore, staff or machines are needed to collect and pack multiple single-piece express bags. This process is cumbersome and inconvenient to transport. At the same time, since the surface of the express bag needs to be waterproofed, a waterproof coating will be sprayed on its surface, and the waterproof coating will affect the adhesion of the glue at the subsequent express paper joints, causing the express bag pieces to be easily pulled apart during use.
