How To Avoid Folding Of Stretched Film

When the stretch film is produced, if the quality control is not good, it is easy to fold. The fold of the stretch film will affect its quality and use. The following Xiaobian will teach you how to avoid the fold of the stretch film.

1, do not let the composite membrane material of the base material position skew, if the skew accumulated to a certain degree, it is easy to produce folds. In addition, it is also necessary to check whether the thickness of the composite film material substrate is uniform. Too large a difference in thickness is also easy to cause the folding of the stretch film.

2, the substrate is easily affected by humidity of the film material, and the occurrence of hygroscopic phenomenon, in the extrusion composite process will be easy to produce folds.

3, control the tension, if the control is improper, the tension of each part is not coordinated, mismatch is easy to cause the stretch film fold.

4. The surface of the guide roller should be kept clean. If there are foreign bodies stuck to it, or the surface of the guide roller is uneven, and there are pits, scratches, bruises and other phenomena, it will lead to wrinkles on the surface of the winding film.

The above is the way to avoid folding of stretch film. I hope it will help you to understand stretch film. If you want to know more about winding film, please pay attention to the dynamics of our company.
