Problems solved by technology

[0004] The application improves the roughness of the adhesive layer and the stability of the adhesive layer by covering the gauze and corona treatment. Although the durability of the printing ink is improved, it will bring new problems. The adhesion of the gauze will directly Affects the performance of the label, therefore, it is more difficult to operate

Abstract

The invention discloses a preparation method of a durable self-adhesive label, which belongs to the technical field of self-adhesive label processing, and comprises the following steps: (1) surface paper pretreatment; (2) pretreating backing paper; (3) gluing; (4) carrying out ultraviolet-ultrasonic coupling treatment; and (5) preparing a finished product. The surface paper and the bottom paper of the self-adhesive label are pretreated, cold plasma-magnetic field circulation alternating treatment is conducted on the surface paper, the stability of the mechanical property of the surface paper is guaranteed while the surface activity of the surface paper is improved, and the surface is fine and smooth. Corona treatment is carried out on the backing paper, and a low-temperature plasma area is formed on the surface of the backing paper through corona with a certain working voltage, so that the surface characteristics of the backing paper are improved. Then the surface paper and the bottom paper coated with the adhesive sticker layers are subjected to ultraviolet-ultrasonic coupling treatment, the cohesiveness of the surface to ink is further improved through the acoustic streaming effect, the cavitation effect, the heat effect, the ultraviolet effect and other effects of ultrasonic waves, and on the other hand, the durability of a finished product is improved.

Description

technical field [0001] The invention belongs to the technical field of self-adhesive label processing, and in particular relates to a preparation method of a durable self-adhesive label. Background technique [0002] Compared with traditional labels, self-adhesive labels have the advantages of no need to brush glue, no paste, no need to dip in water, no pollution, and save labeling time. They have a wide range of applications and are convenient and quick. Self-adhesive is a kind of material, also called self-adhesive label material. It is a composite material with paper, film or other special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper. And after printing, die-cutting and other processing, it becomes a finished label. The printed pattern on the existing self-adhesive label has poor durability, poor adhesion fastness and easy to fall off, which brings inconvenience to the use of the self-adhesive label. [0003] Al...
