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 bottom paper is loaded into the rotary-shaped round labeling machine. At the same time, the tension on the bottom paper is manually adjusted. The tension on the paper is 100N, and the deviation 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: Apply an adhesive to the adjusted and leveled base paper, and paste the top sheet. The adhesive is acrylic latex, and the top sheet is made of polyethylene terephthalate, which has a good waterproof effect. 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 ventilated and dry fac...

Embodiment 2

[0028] The rest is the same as that of Example 1, except that in the step (1), the tension on the paper is 60N, in the step (3), the air-drying time is 3d, and in the 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] The rest is the same as that of Example 1, except that in the step (1), the tension on the paper is 75N, in the step (3), the air-drying time is 2.5d, and in the 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. The surface material of polyethylene terephthalate or polyprop...

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.
