1. Open the outer packaging of the self-adhesive label before labeling, and put it in the labeling workshop for a period of time before labeling. In this way, the label can be fully balanced with the humidity of the labeling environment, and the label will not swell and wrinkle due to excessive water absorption after labeling.
2. To change the processing technology of self-adhesive labels, the lamination process can be used instead of the varnishing process, which can effectively block the label from absorbing external moisture, thereby reducing the probability of wrinkles.
3. During the printing process, the moisture of the label can be increased by means of secondary rewetting. For example, in the process of label processing and die-cutting, a humidifier can be used to humidify the bottom paper of the label to ensure that the label is not too dry, thereby reducing the impact of external humidity changes on the label.
