In the production process of the trademark, there are many complicated links, and the construction quality of each link is directly related to the final quality of the trademark. Once there are loopholes or problems in the link, the quality of the trademark will not be satisfactory. For example, there is an overflow of adhesive in the trademark of adhesive, and there are many reasons for this problem. How to solve it? Let's discuss it together. The label of non-drying adhesive appears excessive adhesive, first of all, we will consider the performance of non-drying label materials, different types of materials have different types of adhesive, before production should fully understand the relevant performance, the selection of suitable processing technology materials. In addition, the ambient temperature for label processing and storage of adhesive labels should be controlled within the range of 23+/-3 degrees centigrade, and the humidity should be controlled within the range of 55+/-5%. Too high temperature will cause the fluidity of adhesive, which is more prone to die-cutting overflow. Next, it is better to use sharp cutting tools in the die-cutting stage of non-drying adhesive trademark. Meanwhile, it should also be noted when die-cutting, too deep die-cutting pressure will cause excessive extrusion on label adhesive, too shallow die-cutting pressure may cause the viscose wire-drawing phenomenon in the die-cutting process, resulting in excessive glue. At the same time, the sliding friction during label processing should be avoided, which may contaminate the label edge and affect the appearance of the product.

In a word, the main causes of the problem of glue leakage are as follows. In order to avoid such problem, special attention should be paid to the die-cutting of the label to ensure the quality of the label.
