Reasons for bending of wet water kraft paper tape
Baijin is a professional wet water kraft paper tape manufacturer . Its products are used for printing high-weight wet water kraft paper tapes, especially those with higher wood pulp content. When printing, the closer to the core, the degree of bending The larger it is, it will be difficult to restore the original shape after bending, resulting in failure to print. Why does the wet water kraft paper tape bend? Is there a way to solve this problem? The root cause of the bending of wet water kraft paper tape: The bending of wet water kraft paper tape is mainly because the temperature and humidity of the environment cause the paper fiber to absorb water or lose water. Since the transverse expansion rate of the fiber fiber is much greater than the longitudinal expansion rate of the fiber, the wet water kraft paper tape will occur when it absorbs water or loses water. Bending, in addition, there is a special feature that causes stress bending under the action of external stress. ...
