Solution to wrinkle of materials in ultrasonic compounding machine

Reduce the tension of the traction substrate. The film is stretched too much, and the setting is not enough. When it is cooled and contracted, it is easy to cause the composite film to wrinkle. Wrinkling can be reduced by appropriately reducing the running tension of the substrate. Adjust the flatness of the substrate If the guide rollers assembled on the dry laminating machine have parallelism errors, some plastic film substrates are easy to produce wrinkles on the guide rollers. During production, the flatness of the base material can be adjusted by adjusting the position of the deflection roller.
