1. If the ambient humidity is too high or the humidity of the film is too high, the paper will be "tight edge", causing the paper to wrinkle. It can be flattened with a platen, and the number of times of tapping and kneading the paper is increased before lamination, and the environment and lamination temperature are reduced.
Second, the roller pressure is uneven, causing the paper to wrinkle during the lamination process. In this case, the roller pressure should be corrected first, and then the machine should be turned on.

3. The rubber roller itself is not flat, causing the paper in the lamination to wrinkle. It should be replaced with a new rubber roller or the old rubber roller should be smoothed for reuse.
4. There is dirt on the rubber roller, which causes the paper to wrinkle when laminating. The rubber roller should be cleaned in time, and the rubber roller must be kept clean frequently.
5. The tensile force is too large, the film is wound and torn, causing the paper to wrinkle when laminating, and the tensile force should be adjusted appropriately.
6. The feeding paper is skewed, causing the paper to wrinkle when laminating. The operation must be careful, so that the feeding paper is flat.
