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

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.

3. Lack of insight into the characteristics of different materials at the time of slitting, distinguishing between control systems and structures
Everyone knows that the physical properties of different materials are inconsistent. Some materials are smooth and firm. Some materials are very soft and soft, and the physical properties of the same material with different thicknesses are not the same. Among the slitting machines, the structure is also different, and there is a lack of changes in the control system due to its structural changes. The difference is rarely studied. In particular, the change in the difference in the control curve is even less known, and its mature control system software is still very few in China. Although some people have tried the application of a slitter control software, the chances of success are very low. Most of them are characterized by “headaches and pains.” Although our company has experienced 7-8 years of hard work, Some experience has been gained and the control system is becoming more mature, but there is still a certain gap compared with the materials covered by well-known foreign brands.

three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:
1. Frame structure: Whether it is a slitting or a second or third slitting, domestic slitting machine manufacturers should invest their energy and study on the frame structure, and actually design a more reasonable slitting machine to get rid of the cutting machine manufacturers. At present, the plagiarism of the slitting machine produced, the research and design of a personalized slitting machine, making the different materials in the structure more detailed, in the next round of international market competition, to provide a favorable weapon for film-making enterprises, At the same time, I also find out the blue ocean for my own company.
