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

three. Irregular end faces

2. The effect of uneven end faces on usage
Regardless of the type and purpose of the film, the problem of "alignment" is involved, and the user generally uses the form of electric eye tracking to perform alignment. The film roll with irregular end faces, the wrong film layer appears to be bent under the pressure of the package, and the electric eye is difficult to track during use, which affects the use effect, such as inaccurate printing overprinting, misalignment of the bag, and the like. In addition, the film roll with irregular end faces is inconspicuous, and the "selling phase" is poor, which affects the brand image of the product.

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.
