Edge: After the self-adhesive label is die-cut and processed into a finished product, Labeling machine the bottom paper is generally left wider than the label. This is to facilitate the removal of the label when the customer is labeling. In the process of label packaging, transportation and handling, Labeling machine it is easy to crack the bottom paper on the edge of the label and cause small cracks. The automatic labeling machine has a certain tension when labeling, Labeling machine and the label with a crack on the edge of the bottom paper is easily broken under the action of the tension, causing the label to break. In addition, Labeling machine improper adjustment of the rollers on the automatic labeling machine may cause the rollers to fracture the bottom paper at the edge of the label and cause the labeling to break. Generally, Labeling machine the labeling is broken by the roller crushing the bottom paper, Labeling machine and the bottom paper has regular cracks.
Tightness: If the finished label is rewinded too tightly, the adhesive in the self-adhesive will be squeezed out, Labeling machine causing the glue to bleed. The oozing glue will stick to the back of the backing paper, Labeling machine making the entire roll of labels difficult to loosen. This situation is especially obvious in summer. If the label is relatively narrow, Labeling machine the tensile strength per unit area of the bottom paper will not be too great.
The automatic labeling machine has a certain tension during the labeling process. When a roll of labels with leaking glue is used for automatic labeling, it is very likely that the bottom paper from which the label is removed will be broken under the action of the tension of the labeling machine and the tension from the inside of the roll during the labeling process. Cause the labeling to break. In the labeling broken tape caused by this situation, Labeling machine the bottom paper breaks irregularly due to the tensile force, but the broken surfaces are relatively uniform.
