Reasons, countermeasures and effects of BOPP film slitting quality ---

Fives. Multilateral

2. The causes and countermeasures of multilateralism:
(1) The mother roll is seriously deviated, wrinkled or uneven in thickness. When the film runs to the sipe roll, it does not stick to the roller and appears multilateral. It is necessary to improve the quality of film production.
(2) Due to the looseness of the parent roll, the floating roller in the slitting process fails to compensate for the slack in the mother roll in time to cause multilateral occurrence. At this time, it is necessary to accelerate to cope with the problem.
(2) The film roll is not effectively adjusted for the bending roll or the high and low roll or the pull wheel, and the flatness of the film during the slitting process must be improved by effective adjustment;
(3) The blade material does not meet the requirements for use, and the texture is too soft or the friction is deformed by heat. Replace the qualified blade;
(4) Poor cutting control, such as too fast slitting speed, slitting speed and poor sheet/pressure setting. Reasonable adjustment.
(5) The process of slitting due to the loss of sand skin can also cause wrinkles and a multilateral phenomenon.
(6) If the unwinding tension is too small, it will also cause multilateral phenomena.

nine. Scratch

     In addition, sometimes scratches due to slitting are difficult to detect by the naked eye, but scratches (scratches) will attenuate the corona value of the product. According to experience, the corona value is reduced by about half in the normal cutting process. Dyne, when the corona values ??differ by more than one dyne before and after cutting, the reasons for the cutting process, such as the speed ratio of the driving roller, the quality of the sand skin, the condition of the sipe roll, etc., should be checked to eliminate the influence. .
     It is worth mentioning that there is a kind of abrasion that is caused by the slitting process, but it is mainly caused by the cutting factor. It is mainly that the mother roll is too loose, and the product of the loose part is horizontally or vertically tilted during the slitting process. While scratching the film surface, it is found that the phenomenon is to install the upper splint on the mother roll for positioning, and secondly, the cutting speed should be properly controlled, and the influence of the quality of the mother roll on the cutting quality can be improved as much as possible.
