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

four. Deviation
Deviation refers to the phenomenon that part of the film on the end face of the film roll is misaligned, which is caused by the sliding of the film during the winding process.

1. The effect of deviation on usage
The effect of deviation on the use is basically the same as that of the end face, which is mainly to track the problem of alignment and the influence on the appearance of the product. Because the degree of misalignment of the deviation is much more obvious than that of the end face, it does not meet the requirements of the customer. Therefore, it must be processed twice, and it can be graded and packed into the warehouse after meeting the requirements.

six. Burr

Another reason for the burrs is the quality of the parent roll.
First, when the mother roll product is wrinkled, the burr phenomenon is likely to occur when the film is cut to the sipe roll and the film is not effectively flattened;
Second, when the film is thick or thin for a long time, the film is prone to burr phenomenon when the film is not attached to the sipe, especially in the triangular position of the thickness. In addition, since the thinner the film, the lower the stiffness, and the higher the chance of burrs.
