The use of stretched film will cause wrinkles after a period of time, which has a very large effect on the use effect. What is the reason for the wrinkles of the stretched film? Let me introduce it below!
1. The thickness of the stretched film substrate is not uniform, and the thickness difference is too large.
2. The position of the stretched film substrate is skewed, which causes the composite film to wrinkle, and as the skewness increases, the degree of wrinkles will increase accordingly.
3. The tension film tension setting and control are improper, and the tension of each part is not coordinated or matched.
4. The composite pressure of the stretched film is not properly set.
5. The axis between the silicone rubber press roll and the cooled steel roll is not parallel.
6. The surface of the guide roller is not clean, there is foreign matter stuck, or the surface of the guide roller is not flat, and there are pits, scribes, bumps and the like.
