Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

(iv) Effect of film roll tightness on product quality

2. The volume is too loose:
1 Shift: Due to the looseness of the winding, the film roll is easy to move in series and shifts. If the degree is serious, it cannot be used.
2 Core-pulling: Due to the looseness of the winding, the film roll has serious end face misalignment near the paper tube during the loading or unloading or use process, commonly known as “core pulling”, which affects the appearance and use effect of the product.
3 The film wrinkles produced by the loosening of the rolls and the pit lines (stars) formed by the tightness of the inner pines affect the appearance quality and the use effect of the products to some extent.
4 Face wrinkles: Due to the looseness of the winding, the point support force of the end face of the film roll during the movement is reduced, and the fish scale-like end face wrinkles are easily generated.
5 Eccentricity: If the winding is too loose, the film roll will be eccentric (elliptical), and the unwinding tension will be uneven during the unwinding process, which will affect the use effect, especially the printing overprinting effect.

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

nine. Scratch
      Whether the slitting and scratching can be compared and determined by the film surface before and after the slitting, there are various reasons for the scratching of the membrane surface, and the analysis should be based on the appearance of the scratch, such as short-line scratching. The difference of the speed ratio of each drive roller exceeds the process setting requirement, and it needs to be carefully tested and adjusted. If the film surface scratch occurs continuously, the film on the slitter should be inspected for whether it touches the fixed object or cuts each. Whether the roller adheres to dirt such as fine sand grains scratches the film surface.
Scratch is the appearance quality problem of the film, which directly affects the quality appearance of the deep-processed product. Therefore, it is not allowed to exist in the film quality control standard. The slitting process finds that the scratching problem must be carefully checked and quickly eliminated. Since the scratch on the film surface is an irreversible appearance quality problem, it is not allowed to operate the disease when the film surface is scratched, so as to avoid the continuous occurrence of the problem.
