1. Poor die cutting. Whether the label is broken during labeling has an important relationship with the quality of die-cutting. Suppose that the die-cutting pressure is too large to cause the bottom paper to be cut through, causing the bottom paper to decrease in tensile strength and cause labeling to break. The cracked surface of the labeling machine labeling broken bottom paper caused by poor die-cutting is relatively uniform, and the crack is in the direction of the die-cutting line. 2. The release layer is damaged. Assuming that the release layer (usually the silicone oil layer) of the backing paper is damaged, it will also cause the label to be broken. If the label is broken due to this condition, the cracked surface of the backing paper is jagged. The cause of the damage to the release layer is the shortcomings of the raw material produced and coated. At the same time, the process of checking and replenishing the standard in the printing plant may also cause the release layer to be scratched due to improper methods. 3. There is a crack on the bottom edge of the label. This is the main reason for the broken label. After the label is die-cut and processed into a product, the backing paper is generally left wider than the label, in order to facilitate the removal of the label when the customer is labeling. However, it is very easy to crack the bottom paper on the edge of the label to form a small crack during the packaging and transportation process. The labeling machine has a certain tension when labeling, and the label with a crack on the edge of the bottom paper is simply pulled off under the effect of the tension of the automatic labeling machine, causing the label to break. In addition, label breakage may also be caused by improper adjustment of the rollers on the labeling machine, resulting in the rollers fracturing the edges of the label. In this case, the label bottom paper has more regular cracks. Fourth, the label is rewinded too tightly, which constitutes glue leakage. When a roll of labels with leaking glue is used for active labeling, it is likely that the backing paper from which the label is removed will be broken under the effect of the tension of the labeling machine and the tension from the inside of the roll during the labeling process. It constitutes a labeling broken tape. The labeling caused by this situation is broken, because the tensile force causes the section to be regular, but the backing paper is cracked irregularly.
