The application of automatic labeling machines is a bit more in the packaging industry or in packaging products. Why? Because products need labels, we usually see a lot of snacks, vegetables, or meat in shopping malls. We don’t know all kinds of products without these labels. The first is the performance of these products, or the price of the products, or the printing of barcodes. Through the current development situation, we can Know the importance of the application of automatic labeling machine! So what is the reason for the automatic labeling machine to break the label? 1. Poor folding die-cutting: The quality of die-cutting also has a great influence on whether the automatic labeling machine is easy to break. If the die-cutting pressure is too large, it will cause the bottom paper to be cut through and cause the bottom paper to resist tension. Decrease in strength causes the label to break. In addition, poor die-cutting will cause the labeling to break with the bottom paper of the bottom paper. 2. Tight folding: If the finished label is rewinded too tightly, it will cause the adhesive in the sticker to be squeezed out, which will cause the glue to leak. The leaked glue will stick to the back of the backing paper and make the label not easy to loosen. open. This situation generally occurs more frequently in summer. If the label of the automatic labeling machine is relatively narrow, the tensile strength per unit area of u200bu200bthe bottom paper will not be very large. The automatic labeling machine has a certain degree of tension during the labeling process. When a roll of labels with leaking glue is used for labeling, it is very likely that the bottom paper from which the label has been removed will be pulled under the action of the tension of the labeling machine and the tension from the inside of the roll during the labeling process. The labeling tape is broken due to breakage. In the labeling broken band caused by such a situation, the bottom paper breaks irregularly because of the tensile force, but the broken surfaces are relatively uniform. 3. The fold is damaged: If the release layer of the bottom paper (usually the silicone oil layer) is damaged, it will also cause the labeling to break. For labeling broken tape caused by this situation, the broken surface of the backing paper is jagged. The cause of damage to the release layer is due to defects in the production and coating of raw materials. At the same time, the release layer may be scratched due to improper techniques in the process of inspection and replenishment in the printing plant.
