Several common marking machine and treatment methods

1. There are cracks on the edge of the label bottom paper

After the self-adhesive label is die-cut into a product, the base paper is generally left wider than the label, so as to facilitate the unveiling of the label when the customer labels. In the process of label packaging transportation and transfer, it is simple to crack the bottom paper on the edge of the label to form a small crack. The automatic opp 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 action of tension, resulting in the labeling broken tape. In other cases, the roller adjustment of the automatic labeling machine is inappropriate, resulting in the bottom paper on the edge of the roller fracturing label forming a labeling broken belt. Generally, the label broken belt is formed by the roller crushing the bottom paper, and the crack of the bottom paper is more regular.


2. Label rewinding is too tight to form percolation

It is assumed that the product label rewinding is too tight, which will cause the adhesive in the self-adhesive to be extruded, and the oozing glue will stick to the opposite side of the backing paper so that the whole roll label is not easily loosened. This is especially true in summer. If the label is relatively narrow, the tensile strength of the paper per unit area will not be too large. The automatic labeling machine has a certain tension in the labeling process. When a roll of labels with gelatinization is used for automatic labeling, it is likely that the bottom paper with the label removed will be pulled apart during the labeling process under the action of the labeling machine tension and the tension from the roll body to form the labeling broken tape. This situation constitutes the label broken belt, which is broken by the pulling force so that the bottom paper is cracked irregular, but the cracking surface is relatively uniform.


Three, poor die cutting

The same die-cutting quality has a great influence on whether the automatic labeling is simple broken tape. It is assumed that the die-cutting pressure is too large to cause the bottom paper to be cut through, causing the tensile strength of the bottom paper to decrease, leading to the label broken tape. The crack surface of the bottom paper caused by poor die cutting is relatively uniform, and the crack is on the tangent direction of the die.


Four, the release layer is damaged

It is assumed that the release layer of the backing paper (generally the silicone oil layer) is damaged, which will also cause the label to break. This condition causes the label to break, and the cracking surface of the backing paper is jagged. The cause of the damage of the release layer is the shortcomings of the raw material production coating, and the release layer may be bruised due to the improper method in the process of checking and supplementing the printing plant.
