Through the reflection light on the surface of the composite bag, you can clearly find out whether the surface of the composite bag is scratched or traces. Most of the drawing phenomenon is caused by the guidance roller of the bag making machine, so it is necessary to ensure that the guide roller is clean. In addition, no rotation of the guide roller will also cause the composite bag to cause drawing failure.

If the surface of the composite bag is curved and tilted out or arched inward, it means that the flatness of the composite bag is poor. On the contrary, this shows that the flatness is good.
