[0002] Self-adhesive label, also called self-adhesive label material, is a composite material made of paper, film or other special materials, with adhesive on the back and silicon-coated protective paper as the backing paper. There are many kinds of labels and processing techniques. For example, the document with the application number 201210520778.6 discloses a method for making a self-adhesive label, which includes the following steps: Step 1, making facial paper, selecting the facial paper that can be written and printed, and then applying it on the surface of the facial paper. The back is coated with a self-adhesive layer, step 2, the backing paper is made, and the silicone oil coating and the PP film are selected to make the backing paper. pattern, step three, the production of labels, combining the self-adhesive layer on the back of the surface paper and the self-adhesive layer coated on the surface of the bottom paper to obtain a finished product, which is clean and environmentally friendly, and can be recycled at the same time, but this process cannot Solve, in the production process, how to ensure that the speed of rewinding and unwinding is synchronized, the force is even, and the bottom paper is flattened, how to make the self-adhesive label, the product does not leave traces after washing with water, how to improve the printing effect and reduce the printing effect. cost, increase printing speed, improve the grade sense of printed matter and market competitiveness

Embodiment 1

[0019] A kind of processing method of self-adhesive label, described processing method comprises the steps:

[0020] (1) Unwinding: Continuous unwinding is adopted, and the backing paper is loaded into the wheel-type round labeling machine. At the same time, the tension on the backing paper is manually adjusted. The tension on the paper is 100N, and the correction is corrected to ensure The speed of rewinding and unwinding is synchronized and the force is even, so that the backing paper can be flattened and the coating operation can be carried out smoothly.

[0021] (2) Coating: smear adhesive on the base paper after adjustment and smoothing, and paste the top material, the adhesive is acrylic latex, and the surface material is polyethylene terephthalate material, and the waterproof effect is good. The product will not leave traces after washing with water, which is conducive to the long-term preservation of labels.

[0022] (3) Drying: place the coated blank label in a venti...

Embodiment 2

[0028] All the other are identical with described embodiment 1, and difference is, in described step (1), the tension force that described paper is subjected to is 60N, and in described step (3), described air-drying time is 3d, and described step ( In 5), the thickness of the ink layer is 300 μm. In the step (7), the embossing pressure is 200 N, and the heating temperature of the heating wire is 177° C.

Embodiment 3

[0030] All the other are identical with described embodiment 1, and difference is, in described step (1), described paper is subjected to tension force is 75N, and in described step (3), described air-drying time is 2.5d, described step In (5), the thickness of the ink layer is 100 μm. In the step (7), the embossing pressure is 150 N, and the heating temperature of the heating wire is 160° C.

[0031] In the above three examples, the obtained self-adhesive labels have the ideal mirror film effect of compactness, smoothness, high gloss and brightness, and can withstand high temperatures above 120°C. under the trace.

[0032] It can be seen from practical application that in the process of self-adhesive label processing, continuous unwinding is adopted, and the backing paper is loaded into the rotary-type circular press label machine. The speed of the roll is synchronized, the force is uniform, and the backing paper can be flattened, which is conducive to the coating operation....

Abstract

The invention discloses a method for machining a self-adhesive label and relates to the label manufacturing field. The method comprises the seven steps of unreeling, coating, stoving, sand blasting, printing, laminating and calendaring. Continuous unreeling is adopted, backing paper is placed on a rotary label machine, tension applied to the backing paper is manually adjusted and correction and rectifying are conducted at the same time, and then Synchronization of the reeling speed and the unreeling speed is guaranteed, stress is even, the backing paper can be flattened, and coating operation is facilitated; the backing paper is placed on a metal surface heated by an electric heating wire and polished to be pressed and cooled gradually till a glossy film surface is formed on a label, clear dopes used for polishing and coating are made denser and smoother, an ideal high-gloss and high-brightness mirror surface film effect is achieved, and the grade and market competitiveness of a printed product are improved.
