A small negligence, hundreds of thousands of sets of labels will be scrapped
[Kein Yin () News] In the entire process of label printing , any problem in one link can bring great economic losses, the same is true for beer labels. When I visited a large brewery, the case of such accidents that the quality control leader of the factory recalled to us has so far reminded me of the new memory. A small negligence, hundreds of thousands of sets of printed labels will be scrapped. [Article content correction description]
The labeling performance of the label is related to the productivity of the beer packaging line. Label waste accident caused by wrong direction of fiber
The labeling performance of aluminized paper labels is directly related to the quantitative, stiffness, flatness, curling, moisture content, back water absorption and other indicators of the base paper, as well as the performance of the labeling machine, the machine adjustment state and the labeling glue characteristics. In addition to the indirect relationship, it is also related to the fiber direction of the label base paper, and the wrong direction of the base paper fiber is the most deadly problem for the beer factory labeling production process.
The brewery's situation at the time was that when a batch of wet-glued beer labels were labelled on the filling production line, serious wrinkles, warping marks, smashing marks, and even frequent marks were found. The beer factory packaging workshop has repeatedly adjusted the labeling machine, and even replaced different types of labeling glue, which can not eliminate the abnormal failure of labeling. After careful observation, analysis, testing and comparison, the results showed that the quantitative, curling, moisture, elongation, tensile strength and other indicators closely related to the labeling quality of the beer labels were in line with the purchase of the brewery. Control quality indicators.
However, although the curling property also conforms to the index, the direction of the curl is completely different from that of other batches. The normal label should be curled inwardly on both the left and right sides, that is, the axis of the curl runs through the label. The label of the labeling abnormality is that the upper and lower sides are curled inward, and the axis of the curl runs through the left and right sides of the label (ie, corresponding to the circumferential direction of the bottle body). That is to say, the batch of labels purchased by the brewery is a problem label produced by the printing plant's process control error. The fiber direction of the paper is used in the wrong direction, and the fiber direction is the circumferential direction of the bottle, not the axial direction. Since the curling direction of the labels is perpendicular to the circumferential direction of the beer bottle, the labeling quality is seriously affected, causing frequent labeling, which makes the canning production unable to be performed normally and interrupted. After the brewery found out the cause of the labeling failure, the brewery decided to stop using the wrong label in the direction of the batch of fibers. The hundreds of thousands of labels that did not meet the labeling requirements were all disposed of for destruction, and the printing factory lost tens of thousands of yuan. . The brewery also affected normal production due to labeling failures, causing certain economic losses.
