In general, when printing domestic packaging paper, the gravure printing method, the flexographic printing method, and the offset printing method have been used to print.

In some plastic papers except for food packaging films, cookie packaging films, ice pack films, etc. which are conventionally used as packaging films for packaging food, etc., braille is formed on the outside of the plastic paper so that the blind can read, but the above food As a packaging film for packaging, etc., conventionally used food packaging film, cookie packaging film, ice pack film, etc. do not form braille, so normal consumers usually print on the outer surface of these food packaging film, cookie packaging film, ice pack film, etc. Information about the food inside can be grasped through the gravure-printed letters, patterns, or logos, but in the case of a blind person who cannot see, he could not know which food was contained in the film of the packaging material.

In addition, UV ink (or UV curable ink) is a method of forming Braille on some of the vinyl papers except for food packaging film, cookie packaging film, ice pack film, etc. which are conventionally used as a packaging film for packaging food, etc. ), but this kind of UV ink has an advantage, but it has a disadvantage that the manufacturing cost is relatively high because it has to be equipped with an ultraviolet dryer.

In addition, as another method of forming Braille on some vinyl papers except for food packaging film, cookie packaging film, ice pack film, etc. which are conventionally used as a packaging film for packaging food, etc., using a prescribed tool, A method has been proposed to engrave braille by inserting a dot paper between the dots, and pressing the dot paper from top to bottom using a dot pen. In this case, there was a problem in that it was not easy to transform the food packaging material film, the cookie packaging material film, and the ice pack film into the braille form only with the pressure of the sticky pen.

In addition, the conventionally used food packaging film, snack packaging film, ice pack film, etc., when food is packaged, when the packaged food packaging film, cookie packaging film, ice pack film, etc. is brought into contact with other foods, these food packaging material films, There was an unsanitary part in which the food that came into contact with the food deteriorated because the outer surface of the cookie packaging film and ice pack film was not treated with antibacterial treatment.

(Example 1)

As shown in Figures 1 to 3, and 5a, the manufacturing method of the packaging material by adhesion of the printing film and the general film of the present invention, the inner film 10 is made of antibacterial treatment on the inner surface; And an inner surface is laminated to the outer surface of the inner film 10, as a method of manufacturing a packaging material film comprising an outer film 20 gravure printed on the outer surface at least one of characters, patterns, and logos, antibacterial treatment step (S1) ), a gravure printing step (S2) of the outer surface of the outer film, a laminating step (S3) of the inner and outer films, and a braille forming step (S4).

In the antibacterial treatment step (S1) of the inner surface of the inner film, the inner surface of the inner film 10 is treated with antibacterial treatment. In this case, it is possible to prevent contamination and deterioration of such food.

In the gravure printing step (S2) of the outer surface of the outer film, gravure printing is performed on the outer surface of the outer film 20. In this embodiment, the gravure-printed ink is a gravure resin ink 50% by weight, a solvent 40% by weight, a fixing agent 5% by weight, preferably including 5% by weight of antibacterial metal nano, but the present invention is not limited thereto. Weight %, a configuration including 3 wt % of antibacterial metal nano is also possible. According to this configuration, even when the packaged food packaging film, the snack packaging film, or the ice pack film is brought into contact with other foods, it is possible to prevent deterioration of the food in contact with these food packaging film, cookie packaging material film, and ice pack film. .

The antibacterial metal nano may also include one or more nano-components of platinum (Pt), gold (Au), titanium dioxide (TiO 2 ), and silver (Ag), which are also packaged food packaging material film, confectionery packaging material film , or even when the ice pack film is brought into contact with other foods, it is possible to prevent deterioration of the foods in contact with these food packaging films, confectionery packaging films, and ice pack films.

In the laminating step (S3) of the inner and outer films, the inner surface of the outer film 20 is laminated on the outer surface of the inner film 10 to form a packaging film.

The braille forming step (S4) is a step of forming braille on the packaging material film, which is heated to form a liquid resin and includes an ink receiving unit and an ink nozzle for accommodating an ink base material that is cured when exposed to air or cold. The ink base material of the head is discharged in the form of drops on the outer surface of the laminated outer film 20 placed in the atmospheric or cold environment through the ink nozzle to form braille. According to this configuration, the ink base material is discharged in the form of drops on the outer surface of the laminated outer film 20 placed in the atmospheric or cold air environment through the ink nozzle and is cured to form Braille that the blind can immediately recognize by tactile sense. can do.

Here, the ink base material consists of 10% by weight of a zeolite resin, 50% by weight of a polypropylene resin, and 40% by weight of a polyethylene resin. Here, since the zeolite does not show a strong exothermic peak up to 600 ° C., it is thermally stable, so that a strong exothermic peak does not appear even when it is discharged in the form of drops by heating, and at the same time, it emits far-infrared rays to have an antibacterial effect, and the poly Since propylene resin is the main component of the ink base material, it is made into Braille to give a harder feeling than other conventional materials when the blind person touches their hand, thereby improving the tactile perception sense of the blind person, and the polyethylene resin is laminated by heating. When it is discharged in the form of droplets on the outer surface of the outer film 20 and cured, the laminated outer film 20 is usually made of polyethylene in most cases, so the adhesiveness or attachment with the laminated outer film 20 improve sex.

To improve the adhesion of the ink to be gravure printed on the outer surface of the outer film 20 and to improve the adhesion density of the ink, the process for improving the adhesion and the adhesion of the ink is performed. In this embodiment, the adhesion of the ink The improvement and ink adhesion density improvement treatment is not limited thereto, but is preferably a corona treatment performed on the outer surface of the outer film 20 . According to this, the adhesiveness of the ink gravure printed on the outer surface of the outer film 20 and the ink adhesion density are improved.
