Several kinds of standard marking and processing methods for labeling machines

Nowadays, the packaging industry is developing. With the improvement of some product packaging, the aesthetic requirements of the products are more strict, and the technical requirements for the labeling machine industry are also improved. The following describes the common types of labeling machines in the labeling process. Standard and processing methods.

First, the edge of the label bottom paper has a crack
After the die-cut label is processed into a finished product, the bottom paper is generally kept wider than the label, which is to facilitate the labeling when the customer labels. It is easy to split the bottom paper of the edge of the label into small cracks during the transportation and handling of the label package. The automatic labeling machine has a certain tension when labeling, and the label with a crack at the edge of the bottom paper is easily broken under the action of tension, resulting in labeling and breaking. In addition, there is also a situation in which the adjustment of the roller on the automatic labeling machine is inappropriate, which causes the bottom paper of the edge of the roller to be cracked to cause labeling and breaking. Generally, the labeling and breaking of the bottom paper caused by the roller crushing of the bottom paper is relatively regular.

Second, the label is too tight and the glue is too tight.
If the rewinding of the finished label is too tight, the adhesive in the adhesive will be squeezed out and the glue will be bleed. The oozing glue will stick to the back of the bottom paper and the whole label will not be easily loosened. This situation is particularly evident during the summer. If the label is narrower than the narrow base paper, the tensile strength per unit area will not be too large. The automatic labeling machine has a certain tension during the labeling process. When a roll of label with a glue phenomenon is used for automatic labeling, it is likely that the bottom paper of the label is pulled off during the labeling process under the tension of the labeler and the tension from the inside of the body. Causes labeling and breaking. The labeling breakage caused by this situation is that the bottom paper breaks irregularly due to the tension pull, but the fracture surface is relatively uniform.

Third, poor die cutting
The quality of the die-cutting quality also has a great influence on whether the automatic labeling is easy to break. If the die-cutting pressure is too large, the bottom paper is cut through and the tensile strength of the base paper is lowered, resulting in labeling and breaking. The fracture surface of the labeling tape with the poor die-cutting is relatively uniform, and the crack is at the position of the die-cut line.

Fourth, the release layer is destroyed
If the release layer of the liner (usually a layer of silicone oil) is destroyed, it can also cause labeling. In this case, the labeling tape is broken, and the fracture surface of the bottom paper is jagged. The cause of the damage of the release layer is the defect in the production of raw materials, and the release layer may be scratched due to improper handling in the printing factory inspection and replenishment process.
