Introduction to the treatment method of broken label of horizontal self-adhesive labeling machine

Horizontal self-adhesive labeling machine is a common type of Zui in recent years, and its technology is also rapidly improving For drug manufacturers, whether from labeling production equipment, or from self-adhesive label and the bottle to be pasted itself, will improve higher requirements Now facing the domestic market of adhesive labeling machine, how can drug manufacturers choose the adhesive labeling machine with higher cost performance ratio will be the problem people pay attention to In the process of production and labeling, the horizontal self-adhesive labeling machine will inevitably encounter various problems The following describes the common handling method of label breaking in the process of labeling: there is a crack on the edge of the bottom paper of the label Self adhesive label in the die-cutting processing into finished products, will generally leave the backing paper wider than the label, so as to facilitate the release of the label when the customer labels In the process of label packaging, transportation and handling, it is easy to crack the bottom paper at the edge of the label, resulting in small cracks The automatic labeling machine has a certain tension when labeling, and the label with a crack on the edge of the bottom paper is easy to be pulled off under the action of tension, resulting in the label breaking In addition, the improper adjustment of the roller on the automatic labeling machine causes the bottom paper on the edge of the label to be fractured and the labeling belt is broken Generally, the bottom paper is broken due to roller pressure, and the cracks of the bottom paper are regular If the label rewinding is too tight, it will cause the adhesive in the adhesive to be squeezed out, which will cause the adhesive to seep The seeping glue will stick on the back of the backing paper, which will make the whole label not easy to loosen This is especially true in summer If the label is relatively narrow, the tensile strength of the base paper per unit area will not be too large The automatic labeling machine has certain tension in the labeling process When a roll of labels with glue leakage is used for automatic labeling, it is likely that the bottom paper of the label removed will be pulled and broken under the effect of the tension of the labeling machine and the tension from the inside of the roll body during labeling In this case, due to the tensile pull, the bottom paper breaks irregularly, but the fracture surface is relatively uniform Poor die-cutting quality also has a great impact on whether it is easy to break in the automatic labeling If the die-cutting pressure is too high, the bottom paper will be cut through, which will cause the tensile strength of the bottom paper to decline and lead to the label breaking The bottom paper fracture surface of the label fracture belt caused by poor die cutting is relatively even, and the crack is at the die cutting line position If the release layer of the backing paper (usually silicon oil layer) is damaged, it will also lead to labeling fault zone This situation will cause the horizontal self-adhesive labeling machine in the labeling process of labeling broken belt, the broken surface of the bottom paper is serrated The reasons for the damage of the release layer are the defects in the coating process of raw material production At the same time, in the process of inspection and supplement of the standard in the printing factory, due to improper techniques, it may also cause the scratch of the release layer.
