Description

A holographic packaging manufacturing method in which a nameplate identification part and a security identification part are provided together and a holographic packaging manufactured thereby {Manufacturing method of holographic packaging with built-in nameplate parts and security parts, and the same}

The present invention relates to a method of producing holographic packaging and to holographic packaging produced thereby. More specifically, when an external light source is irradiated onto the packaging, the holographic design formed on the film is reflected by the reflective layer and is reproduced so that it can be identified from the outside. A holographic packaging production method in which a nameplate identification unit and a security identification unit are provided together to identify the nameplate design from the outside through the nameplate area where a reflective layer is not formed when an internal light source is irradiated to the packaging, and a holographic packaging produced thereby. It's about packaging.

Recently, there has been an increasing number of cases where holograms are added to packaging materials or packaging boxes containing specific contents or items, such as cosmetics or toys, as a means of identifying the manufacturer or the names of each contents or toy. When a hologram is added to packaging materials, etc., it not only differentiates the product from other products due to its unique aesthetics, but is also used as a means of authenticating the product through its anti-counterfeit function.

Conventional hologram formation on packaging materials, etc. involves preparing a hologram master with a hologram convex-convex shape engraved on a glass substrate, then using the hologram master to sequentially produce a metal master and an embossing master, and using this embossing master to create a hologram convex-convex shape on one side of the film. After transferring, a metal thin film is deposited on one side of the film where the uneven shape is formed and then laminated with an adherend such as paper.

However, most of the packaging materials produced by these methods that are currently being proposed reproduce the holographic uneven shape transferred to the film or are reflected by the deposited metal thin film when a light source is irradiated onto the film from the outside. There was a problem in that it could not highlight the differentiation from competing products in that it was composed of a composition that simultaneously reproduces the name plate such as the manufacturer or name recorded along with it.

The present invention was proposed to improve the limitations of the prior art, and the purpose of the present invention is to reproduce the holographic uneven shape that can provide aesthetics of packaging materials, as well as to create a name plate that can identify the name of the product, etc. The aim is to propose packaging that can visually reveal the shape.

In order to achieve this object, the present invention includes the steps of preparing a first digital image of an arbitrary shape; generating a digital interference pattern for each area of the shape forming the first digital image using a computer and converting it into a second digital image; producing a hologram master by recording the second digital image as a hologram of an arbitrary shape on a glass substrate; Manufacturing a metal master using a hologram master; Producing a plurality of unit film replication masters using a metal master, and tiling the plurality of unit film replication masters produced into a film replication master having a certain area; Replicating a hologram film made up of a plurality of unit hologram films using a film replication master having a certain area; Forming a reflective layer on each surface of each unit hologram film of the hologram film, excluding the name plate portion having an arbitrary shape; Laminating the hologram film with a reflective layer formed on the adherend except for the name plate area; There is a technical feature including the step of cutting the laminated hologram film and the adherend into unit hologram film unit packaging.

The name plate is composed of a design or letter having an arbitrary shape, or a combination thereof; The adherend may be made of a transparent or translucent film.

Preferred embodiments according to the present invention will be examined in detail with reference to the attached drawings as follows. In describing the embodiments of the present invention in detail, there is no direct relationship with the technical features of the present invention, or general knowledge in the technical field to which the present invention belongs. Detailed explanations will be omitted for matters that are obvious to those with knowledge.

The present invention relates to a method of producing holographic packaging and holographic packaging resulting therefrom, comprising the steps of producing a metal master using a hologram master, and producing a film replication master in which a plurality of unit film replication masters are prepared using a metal master. , producing a film replication hologram, forming a reflective layer, and then laminating the adherend; It has the characteristic of including the step of cutting into a unit hologram film. Let’s look at each of these steps in detail.

First, prepare a first digital image of a random shape. The shape of the first digital image is not specified and may be composed of real images, shapes, letters, symbols, or a combination thereof. In addition, in the case of the first digital image, it is not excluded that it consists of a 3D image as well as a typical 2D image.

When the first digital image is prepared, it is converted into a second digital image. The conversion to the second digital image involves converting the shape of the first digital image into an interference pattern using a typical computer generated hologram (CGH) and then implementing it as a second digital image. The process is widely known in the related industry, so detailed description is omitted.

Figure 2a shows examples of second digital images converted using a computer-generated hologram. The disclosed second digital images show various examples of preparing different first digital images and then converting each of them into a computer-generated hologram.

When the first digital image is converted into a second digital image, a hologram master is produced using this. The hologram master can be made by recording the shape of the second digital image as an uneven shape 13 on the glass substrate 10, as shown in (a) of FIG. 1, using an optical system as shown as an example in FIG. 2B. .

The optical system illustrated in Figure 2b includes a light generating device and a reflector made of a laser, a spatial light modulator, a work plate on which a glass substrate is placed, a drive motor that moves the work plate at regular intervals in the X and Y directions, and a control device such as a computer. It may include, and since this optical system configuration may also be comprised of any one widely known in the related industry, detailed descriptions and operations related thereto will be omitted.

When the second digital image is recorded on a glass substrate and a hologram master is produced, a metal master 20 such as (b) in FIG. 1 is produced using this. As is widely known in the related industry, the metal master 20 is formed by forming a conductive thin film layer on the upper surface of a hologram formed in a concavo-convex shape 13 on one side of a glass substrate 10 (see FIG. 2C), and then conducting it using nickel, etc. This can be done by plating a certain thickness of metal on the upper surface of the thin film layer (see Figure 2d).

Accordingly, the uneven shape 13 formed on one side of the glass substrate 10 is transferred to one side of the metal master 20, thereby forming the uneven shape 23. Once the metal master is produced, a film reproduction master with a certain area is produced using it. Film Replication Master can be produced in the following way.

First, a certain amount of UV resin is applied to one side of the metal master where the holographic uneven shape is transferred. When UV resin is applied to one side of the metal master, one side is covered with a film made of PVC or PET, and then, through a laminating process, UV light is irradiated to transfer the uneven shape to one side of the film (see Figure 2e). ). At this time, it is preferable to use an acrylic or urethane coated film to improve adhesion to UV resin.

Once the uneven shape is transferred to one side of the film, the uneven shape is transferred to the other side of the film in the same manner. When transferring a plurality of uneven shapes to one side of the film, adjacent uneven patterns are tiled without overlapping, and when this work is completed, each of the identical uneven shapes (33, A film duplication master 30 of a certain area equipped with a plurality of unit film duplication masters 31 and 35 (37) is manufactured.

The above-described method is a UV tiling method, but the present invention is a method widely known in the related industry when producing a film replication master, in which a metal master is attached to a pressurized device and then applied to one side of a polycarbonate or acrylic plate using heat and pressure. Of course, a mechanical tiling method of continuously tiling is not excluded.

FIG. 2F shows an example of a film replication master produced by tiling each of the unit film replication masters shown in FIG. 2E. This example shows the case of using unit film replication masters with different concavo-convex shapes, but it is of course possible to produce a film replication master by tiling unit film replication masters with the same concavo-convex shape.

When a film duplication master having a certain area is prepared, the hologram film 40 having a certain area provided with a plurality of unit hologram films 41 and 45 is duplicated, as shown in (d) of FIG. 1. The same uneven shapes 43 and 47 are transferred to each of the hologram films 41 and 45 provided in the hologram film 40. The hologram film may be made of a material similar to the film reproduction master. Figure 2g is an example of a hologram film replicated using the film replication master of Figure 2f.

When a hologram film having a certain area is copied, a reflective layer 50 is formed on the top of the uneven shapes 43 and 47 formed on each of the unit hologram films 41 and 45 among the hologram films 40, as shown in (e) of FIG. 1. forms. The reflective layer 50 formed on top of each of the uneven shapes 43 and 47 may be made of an aluminum deposition layer having a certain thickness or a continuous deposition layer of aluminum dioxide and titanium dioxide. Figure 2h shows an example of forming a reflective layer on the hologram film of Figure 2g.

At this time, a name plate is provided on each reflective layer formed on one side of each unit hologram film. The nameplate may consist of a design or text of any shape, or a combination thereof, and may include the logo or brand of the product manufacturer or manufacturer, or a design specified by the manufacturer or manufacturer.

The name plate provided on the reflective layer of each unit hologram film is a transparent portion where the reflective layer 50 is not formed among the uneven shapes 43 and 47, as indicated by reference numeral 60 in (e) of FIG. 1, and is a unit hologram film. When forming a reflective layer on each by a method such as vacuum deposition, one of various methods such as printing or attaching backing paper to the corresponding area can be used to prevent the reflective layer from being formed in the name plate area.

Meanwhile, the present invention does not exclude the case where a printing layer of various colors is added to one side of each unit hologram film before forming a reflective layer on one side of each unit hologram film. In this case, a color effect caused by the printed layer can be expected when the hologram is reproduced by passing through the unit hologram film and then being reflected by the reflective layer. The printing layer can be performed by silk screen printing.

When a reflective layer is formed in each unit of the holographic film that makes up the holographic film except for the nameplate portion, the hologram film with the reflective layer except for the nameplate portion is laminated with the adherend 70, as shown in FIG. 1(f). do. The adherend 70 may be made of various materials such as paper and film, and if it is necessary to recognize the name plate area from the outside, it is preferable to use a transparent or translucent film. Figure 2i shows an example in which a transparent film is laminated to the hologram film of Figure 2h.

When the hologram film is laminated with the adherend, the hologram film having a certain area is cut into individual packaging units, as shown in Figure 1 (g). Of course, the specific size of the unit packaging can vary depending on the size of the packaging paper or packaging box. Figure 3 shows various examples of unit packaging manufactured and cut according to the present invention. In the example, the English part is the nameplate part.

4A and 4B are examples of unit packaging manufactured according to the present invention applied to a packaging box (not shown), assuming that an internal light source 120 such as an LED is mounted on a PCB board 110 inside the packaging box. It was done. In this case, a separate battery (not shown) needs to be provided on the PCB board 110.

As shown in the figure, when the internal light source 120 turns on and illuminates the unit packaging, the light irradiated to the area where the reflective layer 50 is formed in the unit packaging is reflected and does not transmit to the outside, and the light irradiated to the area where the reflective layer 50 is formed is reflected and does not transmit to the outside. As the light irradiated to the name plate 60 is projected to the outside through the name plate 60, the user can identify the shape or text of the name plate from the outside.

On the other hand, when the external light source is irradiated to the unit packaging while the internal light source 120 is turned off, the light irradiated to the portion of the name plate 60 where the reflection layer 50 is not formed is transmitted through the name plate 60. The light projected into the unit packaging and irradiated to the area where the reflective layer 50 is formed is reflected by the reflective layer 50 and reproduces the uneven shape H formed on one side of the unit packaging so that the user can identify it.

In this way, the present invention forms a reflective layer on one side of the holographic concave-convex shape, but does not form a reflective layer on the nameplate area made of figures or letters, so that the holographic concavo-convex design as a security identification unit can be reproduced through an external light source. Of course, it is possible to reproduce the nameplate design as a nameplate identification unit externally through an internal light source.

Although the description above is limited to preferred embodiments of the present invention, this is only an example, and the present invention is not limited thereto and can be modified and implemented in various ways, and further, separate technical features are provided based on the disclosed technical idea. It is obvious that it can be added and implemented.
