Film Laminating Machine

How to solve wrinkles in the Film Laminating Machine , wrinkles in the film, in fact, this problem is widespread, and because of this, the problem of wrinkling of the film has become a problem that has been discussed in the post-press processing industry. Wrinkles appear in the film. How to solve it?

The reasons and solutions for the wrinkling of the Film Laminating Machine are as follows:

1. Vertical wrinkles.
 The film pull is too large, the pressure is not flattened, and there is a crease in itself, so wrinkles are formed after the film is finished.
Solution: Relax the film tension, adjust the spreader roll, and flatten the film before pressing.

2. Oblique wrinkles.
The film has large pulling force and improper adjustment of the roller position, resulting in inconsistent tightness of the film itself, uneven film transfer, and regular folding to the loose side.
Solution: Relax the film tension, adjust the stretch roll or temporarily change the film.

3. Horizontal wrinkles.
When the temperature of the heating roller is too high, the pressure of the rubber roller is too large, and the film is laterally creased into a lateral wrinkle when compounded.
Solution: Reduce the roll temperature or reduce the pressure of the rubber roller.
