Before talking about the printing process and processing method of self-adhesive labels, we should first understand what is the printing of self-adhesive labels, and what is the difference between it and traditional label printing. Self adhesive labels are also called self-adhesive labels. They are made of paper, film or special materials, coated with adhesive on the back, and silicon coated protective paper as the base paper. They are printed, die cut, and then become finished labels. During application, it is only necessary to peel off the backing paper and press it gently to paste it on the surface of various substrates, or use the labeling machine to automatically label on the production line.
Compared with traditional labels, self-adhesive labels do not need to be painted, pasted or dipped in water. They are pollution-free, save labeling time, and are convenient and fast to use in various occasions. Various labels of different fabrics, adhesives and backing paper can be applied to materials that ordinary paper labels are not competent for. It can be said that self-adhesive is a universal label. The printing of self-adhesive labels is very different from the traditional printing. The self-adhesive labels are usually printed and processed on the label linkage machine, and multiple processes are completed at one time, such as graphic printing, die-cutting, waste disposal, cutting or rewinding. That is, one end is the raw material input of the whole roll, and the other end is the finished product output. The finished products are divided into single or roll labels, and the finished product labels can be directly applied to the goods. Therefore, the self-adhesive label printing process is more complex, and the requirements for equipment performance and printing staff quality are also higher.
While talking about the printing and processing technology of adhesive labels, we must also understand the basic structure and functions of each part of the adhesive materials as printing materials. The structure of the self-adhesive material is from the surface, that is, the surface material, the adhesive and the backing paper, that is, the self-adhesive printing material is composed of three parts.
