Causes of stretch wrap wrinkles
Source：Causes of stretch wrap wrinklesTime：2019-04-01Visitors：
1. The thickness of the stretch-wound film substrate is not uniform, and the thickness difference is too large.
2. The position of the stretched stretch film substrate is skewed, which causes the composite film to wrinkle, and the degree of wrinkles increases correspondingly with the accumulation of skewness.
3. The tension setting and control are improper, and the tension of each part is not coordinated or matched.
4. The composite pressure is not set properly.
5. The axis between the silicone rubber press roll and the cooled steel roll is not parallel.
