Reasons, countermeasures and effects of BOPP film slitting quality ---
two. Wrinkles (wrinkles, vertical wrinkles, cross wrinkles, wrinkles)

 

(2) Causes and countermeasures of longitudinal wrinkles
Longitudinal wrinkles mean that the surface of the film roll forms a circumferential rib line. In the process of slitting, a large amount of air entrapment or cumulative thickness unevenness is the main cause of longitudinal streaks, and it is difficult to eliminate the occurrence of a relatively serious stripe. When the longitudinal wrinkles appear in the slitting process, the tension is reduced and the pressure is applied to discharge the air in the film roll to improve the longitudinal wrinkle problem. However, the adjustment range should consider the impact on wrinkles and other aspects (according to relevant professional information, longitudinal wrinkles One of the reasons is that the slitting speed is too fast, and the film roll is most prone to the quality problem of the longitudinal stripe at high speed, but there is no obvious influence in actual production, which remains to be studied). Another reason for the vertical wrinkles is the influence of the running accuracy of the equipment. For equipment with high requirements for running accuracy, after a long period of continuous use, the running accuracy of some components has decreased. For large slitting machines, it is more difficult to ensure the running accuracy due to the large number of running parts. Moreover, since the plastic film is a polymer product, its thickness is very thin, and it is more susceptible to damage during processing. Therefore, once the running accuracy is insufficient, quality problems such as vertical streaks are likely to occur. For this reason, it should be cautious when replacing equipment parts and accessories. It is advisable to use durable and high-precision parts, and it must also ensure a certain precision during installation. Otherwise, it is difficult to meet the operation requirements of the slitting machine.
The flattening roller flattens the film and eliminates some of the longitudinal wrinkles produced by the film under tensile stress.
(3) Causes and countermeasures of cross wrinkles
In addition to the influence of the parent-rolling factor, the transverse wrinkles of the film are mainly caused by the sag-like transverse wrinkles produced by the loosening of the slit film roll. Generally, the slitting process is effective in reducing the wrinkles and reducing the pressure, and should be effective for different types of products. Adjusting the slitting and pressure can effectively eliminate the occurrence of cross wrinkles.

ten. Color circle
The color circle is caused by a certain degree of contamination inside or outside the film, which causes the quality of the color circle on the end face of the film roll after slitting and winding. Membrane surface pollution sources come from two aspects. One is the film-forming process. The color circles generated in the front part of the film, such as raw materials, feeding systems, extrusion systems, and die flow channels, generally cause pollution to the inside of the film (core layer). Some color-circle products can clearly observe a large amount of fish-eye impurities in the film. The color circles generated in the film-forming stage and the slitting process mainly cause pollution to the outside (surface) of the film, but whether it is internal or external pollution, It is impossible to remove the impurities from the contaminated film and restore the original appearance. The product with serious color circle has low transparency, the film color is different from the normal product, and it can not be used at all. It can only be reduced to other external treatments, while the products with slight color circles are It has little effect on the transparency of the product and does not affect the use effect of the single film. However, due to the inconspicuous appearance of the color circle product, the “selling phase” is poor, which has a great influence on the image of the German brand. It is not suitable for direct delivery. Secondary processing. If the color circle is caused by external dust pollution factors, the dust will be adsorbed on the surface of the film, resulting in poor quality of heat sealing and poor laser compression.
