two. Wrinkle (wrinkle, vertical wrinkle, cross wrinkle, line wrinkle)
1. The effect of wrinkles on the quality of use
BOPP film is commonly known as "cellophane", which reflects the film's high stiffness, high transparency and good gloss. The film is wrinkled, which means that the flatness of the film is damaged to a certain extent. This is not allowed for any film. Not only will it affect the appearance of deep-processed products, but also cause quality defects in use, such as lack of coating, lack of printing, and so on. 2. Causes and countermeasures of wrinkles
The wrinkles caused by the slitting of the film have various forms such as wrinkles, longitudinal wrinkles, cross wrinkles, and line wrinkles, and the causes are also different, as follows:
(1) Wrinkle: also known as bottom wrinkle, initial wrinkle, etc., is the wrinkle appearing in the section of the original winding film of the paper core. Since the wrinkle is mostly irregular wrinkles, the user generally uses the film to wrinkle. Disposal. The degree of wrinkling is an important indicator reflecting the level of cutting technology of a BOPP film company. The film produced by different companies has a wrinkle length ranging from a few meters, tens of meters to several hundred meters, and the more serious the wrinkles, the more The greater the losses caused by users, therefore, each film company is committed to improving the research of slitting and wrinkle. Through many years, the BOPP industry has carried out a series of intensive and meticulous work on solving the problem of wrinkling. From the two aspects of process parameter screening and equipment adjustment and transformation, we have found a set of effective solutions and received very good results. effect,
Reasons, countermeasures and effects of BOPP film slitting quality ---
Seven. Sharp edge
The curling occurs at the edge of the film winding, which causes the curling. The reason is that the edge of the thick film is curled up and the edge part is lifted up; the second is that the winding is too tight, and the tension can be shortened by slitting. Speed ??to improve the resulting edge curling phenomenon; third, the cutter is too blunt, and the stretching phenomenon occurs at the slit when slitting, causing the edge of the film roll to be turned outwards after winding to cause the curling edge, and the cutting should be replaced in time. The knife can avoid the occurrence of the curling problem; the fourth is that the tool is not installed correctly, such as the blade is close to the edge of the sipe and the blade is passivated. Cutting with a round knife can improve the curling of the film roll.
In the use of the unwinding process, there will be different degrees of side-floating in the unwinding process, and it is impossible to track the alignment with the electric eye, which directly affects the use effect. Therefore, it is necessary to change the product with the curled edge.
