Abstract

The present invention relates to a shrink film pattern printing processing method, and in particular to a shrink film pattern printing processing method that prevents a pattern on the shrink film from being distorted after the shrink film is shrunk, and comprises an adhesive coating step, a hot stamping step, an adhesive secondary coating step, a coating printing step, a transfer glue coating step, and a pattern transfer step; wherein a particle setting step, a lamination step, and an adhesive tertiary coating step are sequentially added between the adhesive secondary coating step and the coating printing step. Through the above-mentioned shrink film pattern printing processing method, the present invention can set a preset gap between complete transfer patterns, and the preset gap prevents the pattern from being severely distorted and deformed when the shrink film shrinks, resulting in a situation where the pattern cannot be determined.

Description

Shrink film pattern printing processing method

technical field

The invention relates to a shrink film pattern printing processing method, in particular to a shrink film pattern printing processing method that prevents the pattern on the shrink film from being distorted and deformed after shrinking.

Background technique

Generally, when the product is manufactured and packaged, most of the product will be placed on the product with a shrink film, and the shrink film can be used to package the product by using the heat shrinkable packaging effect, so that the product can be isolated from the outside air and environment to keep the product Freshness or to avoid the pollution of the external environment.

In order to increase the effect of patterns and trademarks on the appearance of the product, most of the industry will print the pattern on the shrink film, please refer to Figure 2, the way to print the pattern is mostly to prepare a transfer paper with a complete pattern , and then coated with an adhesive on the transfer paper, after bronzing treatment on the complete pattern and coating of the transfer adhesive, the complete pattern can be transferred to the shrink film used for product packaging for use .

However, when using the patterned shrink film made by the above method, due to heat shrinkage, the complete pattern transferred on the shrink film will be distorted and deformed. In severe cases, consumers cannot even judge the shrinkage. What is the pattern printed on the film, so the printing method of this kind of shrink film pattern needs to be further improved.

Contents of the invention

The main purpose of the present invention is to overcome the deficiencies and defects of the prior art, and provide a shrink film pattern printing processing method that prevents the pattern on the shrink film from being distorted and deformed after shrinking.

In order to achieve the above-mentioned purpose of the invention, the present invention provides a shrink film pattern printing processing method, which includes the adhesive coating step of coating the adhesive on the transfer paper with the pattern, and the bronzing step of performing bronzing treatment on the adhesive. Steps, the adhesive secondary coating step of coating the adhesive on the bronzing layer after the bronzing treatment, the paint printing step of printing the paint on the adhesive of the pattern, the transfer glue coating of coating the transfer glue on the paint The cloth step, the pattern transfer step of transferring the pattern to the shrink film; wherein between the adhesive secondary coating step and the paint printing step, additional particles are set on the pattern, and there is a predetermined gap between the particles The particle setting step, the pressing step of tightly bonding the particle and the adhesive, and the three adhesive coating steps of coating the adhesive on the pattern after the pressing step.

Through the above-mentioned shrink film pattern printing and processing method, the present invention can set a preset gap between the complete transfer patterns, and the preset gap will prevent the pattern from being severely distorted and deformed when the shrink film shrinks, resulting in failure The situation where the pattern is judged occurs.

Fig. 2 is a flow chart of the existing method.

Detailed ways

Referring to Fig. 1 , the method for printing and processing the pattern of the shrink film of the present invention will be described in detail.

The inventive method comprises:

Adhesive coating step: the adhesive coating step is to apply adhesive on transfer paper with pattern;

Bronzing step: the bronzing step is to perform bronzing treatment on the aforementioned adhesive;

Adhesive secondary coating step: the adhesive secondary coating step is to coat the adhesive on the bronzing layer after the aforementioned bronzing treatment;

Paint printing step: the paint printing step is to print paint on the adhesive of the pattern;

Transfer printing glue coating step: the transfer printing glue coating step is to apply transfer printing glue on the paint;

Pattern transfer step: the pattern transfer step is to transfer the pattern to the shrink film;

Among them, between the above-mentioned adhesive secondary coating step and the paint printing step, there are added in sequence:

Particle setting step: the particle setting step is to set particles on the pattern, and a predetermined gap is set between the particles;

Pressing step: the pressing step is to tightly bond the particles and the adhesive, and;

Steps of applying the adhesive three times: the step of applying the adhesive three times is to apply the adhesive on the pattern after the pressing step.

The above step of disposing the particles is to use, for example, screen printing to place the particles at predetermined positions inside the pattern, so that a predetermined gap is formed between the particles, wherein the particles can be glass beads.

The patterned transfer paper used in the above adhesive coating step is the existing transfer paper, and the adhesive used can be ink or viscous colloid. The above bronzing step can utilize the existing bronzing methods such as cold stamping, hot stamping, etc. that can coat light-reflective powders such as gold powder and silver powder on the surface of the object.

In the pressing step above, the pressure wheel is used to apply pressure to the particles, so that the particles can be tightly pressed with the adhesive.
