Custom-made plastic packaging bags are one of the materials we use. The flatness of plastic packaging bags is also one of the important standards to measure their quality. Now let's take a closer look at this knowledge introduction?
Speaking of the factors of the flatness of the plastic packaging bag, first of all, it has a lot to do with the adjustment of the warp tension. Generally, in the process of adjusting the warp tension, it is mainly through the guide holes passing through the creel and the flat yarn. 1. The warp let-off roller and the jump bar are carried out. If the warp tension is not balanced, there will be a big problem in the flatness of the product produced, and this must be paid attention to. The second is the rotation resistance torque of the tray shaft of each spindle of the warp yarn rack, which directly affects the source of the warp tension.
During the production process, the flatness of the plastic packaging bag is caused by a variety of factors. If the method of production is not correct, it will have a certain impact on the quality of the product in the future.
