Analysis of the reasons for the label breaking of the paste labeling machine-industry news

When using a paste labeling machine, we often encounter the situation that the self-adhesive label is broken. The following editor briefly teaches you how to distinguish the reason for the self-adhesive label breaking: 1. There is more information on the edge. It is good for work. After the self-adhesive label is die-cut and processed into a product, the bottom paper is generally left wider than the label. This is to facilitate the peeling of the label when the customer is labeling, and it will not waste time. In the process of label transportation and transfer, it is easy to crack the bottom paper at the edge of the label to form a small crack.　　　　 paste labeling machine has a certain degree of tension during labeling, and labels with cracks on the edge of the bottom paper are easy to be pulled and cause the labeling to break. In addition, the improper adjustment of the rollers on the labeling machine caused the rollers to fracture the bottom paper at the edge of the label and cause the labeling to break. Generally, the labeling broken band formed by the roller crushing the bottom paper, the bottom paper has more regular cracks.　　　　 2. Tight formation 　　　　 If the label is rewinded too tightly, the adhesive in the self-adhesive will be squeezed out, causing the glue to bleed, and the oozing glue will stick to the back of the backing paper to make the entire roll of labels difficult to loosen. This situation is particularly noticeable in summer. If the label is relatively narrow, the tensile strength per unit area of u200bu200bthe backing paper will not be too great. The paste labeling machine has a certain tension during the labeling process.　　　　During the labeling process, it is very likely that the backing paper from which the label has been removed will be broken under the effect of the tension of the labeling machine and the tension from the inside of the roll to form a labeling broken band. The labeling broken band formed under this condition has irregular cracking of the bottom paper due to the tensile force, but the cracking surface is relatively uniform.
