[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging material having an area having a metallic luster and a mat-like area having a metallic appearance, for example, a decorative effect for packaging toilet soap, cosmetics, high-grade Japanese and Western confectionery, and the like. The present invention relates to a decorative packaging material for an exterior having a high level.

[0002]

2. Description of the Related Art In recent years, as a packaging material for exterior having a metallic luster area and a matte area and having a high decorative effect, for example, as shown in FIG. On the back side of the pattern layer (25) made of transparent coloring ink or a character or picture layer (22) made of synthetic resin ink, aluminum is provided from the side of the pattern layer (25) made of transparent coloring ink provided on the transparent plastic film (20). This is a packaging material provided with a metal vapor deposited layer (23) such as the above on the entire surface, and further provided on the surface with a suitably patterned mat varnish layer (24) other than at least the region of the pattern layer (25) made of transparent coloring ink.

As shown in FIG. 2 (b), a pattern layer (25) made of transparent coloring ink and a character or picture layer (22) made of synthetic resin ink are formed on the back surface of the transparent plastic film (20).
On the other hand, a metal vapor deposition layer (23) is provided in a pattern from the pattern layer (25) side of the transparent plastic film (20) on which a mat varnish layer (24) is appropriately provided in a pattern on the surface. It is.

The packaging material shown in FIGS. 2 (a) and 2 (b) is used so that the metal-deposited layer is on the back side (S) and is observed from the front side (K). The pattern-like mat varnish layer (24), the pattern layer (25) made of the transparent coloring ink on the back side (S), and the metal vapor deposition layer (23) provide a packaging material having a mixture of a matte tone region and a metallic luster region.

[0005]

However, the mat varnish used in the conventional mat varnish layer (24) has a low mat effect only with a normal mat agent. Therefore, if the particle size of the matting agent is increased to increase the matting effect and the amount of the matting agent is increased, the adhesive strength of the matting varnish is reduced, and the matting varnish is easily peeled off, for example, by hand rubbing. Also, when observed from the front side (K), the overlap between the pattern layer (25) made of transparent coloring ink and the pattern-like mat varnish layer (24) is conspicuous, and the decorative effect is reduced, and the transparency is reduced, and the characters and picture layers ( 22) disappears.

To avoid this, there is a method in which the pattern layer (22) is formed by hot stamping using a metal foil. However, it is difficult to register the front and back of the pattern layer with the pattern-like mat varnish layer (24), and as a packaging material, Decoration was a problem.

Accordingly, the present invention examines a lamination structure by a printing method, enhances the mat effect, and provides a highly decorative packaging material having a matte area having a metallic feeling and a pattern area having a metallic luster. Aim.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail. Fig. 1 (a)
1 is a side view showing a laminated structure of a decorative packaging material according to an embodiment of the present invention. FIG. 2B is a side view showing an example of the vapor deposition film.

As shown in FIG. 1 (a), as the transparent plastic film (10) as a base material, a film made of polyester, polyethylene, polypropylene, polyvinyl chloride, acrylic, or a composite material thereof can be used as appropriate. Can be.

The pattern layer made of the transparent coloring ink (12)
Is a gravure printing method using transparent yellow ink for printing,
A pattern layer (12) such as a character or a picture is provided by printing on a partial area on the back surface of the transparent plastic film (10) by an offset printing method or a screen printing method, and opaque in other parts. The picture layer (13) is provided by using the synthetic resin ink described above.

Further, the pattern layer (12) and the picture layer (13)
This is a configuration in which a transparent colored synthetic resin layer (11) is provided so as to cover the top. The transparent colored synthetic resin layer (11) is formed by appropriately selecting a pigment such as sumi, yellow, red, and indigo in a urethane-based, rubber-based, vinyl-based, polyamide-based, or nitrification-ray-based resin.
This is a printing ink having high transparency mixed with a weight%.

Subsequently, a metal deposition layer (1) having a thickness of, for example, 100 to 400 mm is formed on the entire surface of the printing base sheet (P) on the transparent colored synthetic resin layer (11) side by using a metal such as aluminum.
8) on a substrate (16) such as a polypropylene film, a low-density polyethylene film, a polyethylene terephthalate film, or paper (all having a thickness of about 10 μm to 50 μm), and a laminated film (V). When a vapor-deposited polyethylene terephthalate film or vapor-deposited paper is used, a sealant film may be further attached.

On the other hand, the transparent plastic film (10)
The alkyd synthetic resin or the olefin resin is coated with a silica-based or carion-based matting agent in an amount of 2% to 1% so as to slightly overlap the pattern layer (12).
A mat synthetic resin layer in which white synthetic resin ink is further added and mixed with 15% to 50% by weight to a mat varnish added with 0% by weight.
(15) is provided by printing. However, when the matting agent is added in an amount of 10% by weight or more, the printability deteriorates.
When the amount of the white synthetic resin ink is 50% by weight or more, the transparency becomes low and the lower picture layer (13) becomes difficult to see. Further, in printing of the mat synthetic resin layer (15), a reverse plate (negative printing plate) of a printing plate (positive printing plate) of the pattern layer (12) is used for front and back printing register alignment with the pattern layer (12). Printed using

Hereinafter, specific embodiments will be described.

<Example 1> A transparent biaxially stretched polypropylene film (corresponding to a corona discharge treatment on both surfaces) (for example, a thickness of about 10 μm to 80 μm) was used as a printing substrate (transparent plastic film 10), and a transparent region was formed on a part of the rear surface. A pattern layer (12) of characters and patterns with yellow ink and a pattern layer (13) with opaque synthetic resin ink are printed, and the entire surface is coated with urethane-based resin and 5% by weight of a suitable colored pigment. A transparent colored synthetic resin layer (11) was provided by printing using a high printing ink. Further, a polyethylene terephthalate resin film (16) (evaporated film V) obtained by applying aluminum evaporation (18) to the entire surface of the printed base sheet (P) on the pattern layer (15) side and a sealant film (for example, polyethylene, unstretched polypropylene) Film) are laminated by a dry lamination method via an adhesive.

On the other hand, on the surface side of a biaxially oriented polypropylene film as a base material, 8% by weight of a silica-based matting agent and 30% by weight of a white synthetic resin ink mainly containing titanium pigment are added to an alkyd-based synthetic resin. The matte synthetic resin layer (15) having a mat amount of 7% by weight is mixed so as to slightly overlap the pattern layer (12) region using a reverse version (negative printing plate) of the pattern layer (12). Provided by printing. This allows the front side (K)
From a further observation, a packaging material having a gold-like pattern layer (12) with a metallic luster and a matte region with a metallic feeling was obtained.

Table 1 shows the results of evaluation of the degree of adhesion of the mat synthetic resin layer (15) to the transparent plastic film (10) and the mat effect when the amount of the white synthetic resin ink mixed was changed.

[0019]

[Table 1]

From the results shown in Table 1, it can be seen that the transparent colored synthetic resin layer (11) overlapping the mat synthetic resin layer (15) to which the white synthetic resin ink was added significantly reduced the amount of the pigment to be added (10% by weight or less). Thus, it became possible to express pale matte tones. Also, even if there is a slight overlap between the pattern layer (12) and the matte synthetic resin layer (15) by the transparent coloring ink (transparent yellow ink), since the white synthetic resin ink is mixed, the transparent coloring of the overlapping part is performed. The pattern layer (12) made of ink became inconspicuous.

[0021]

According to the present invention, as shown in FIG. 1, a pattern layer (12) made of transparent coloring ink and a pattern layer (13) made of opaque synthetic resin ink are provided in a partial area on the back surface of a transparent plastic film (10). A transparent colored synthetic resin layer (11) is provided from above, and a metal deposited film (V) is laminated on the entire surface,
On the other hand, on the surface side of the transparent plastic film (10), a packaging material having a configuration in which a mat synthetic resin layer (15) is provided so as to slightly overlap the pattern layer (12) region of the transparent coloring ink, Observed from the front side (K), the printing register is aligned with the positive printing plate and the negative printing plate (reverse printing) in the gold-tone area with metallic luster and the matte area with metallic feeling, and clearly separated and visually recognized In addition to being a decorative packaging material, the matte synthetic resin layer (15) is enhanced by adding a matting agent and a white synthetic resin ink to enhance the matte tone.
Honeycomb adhesion to 0) can be strengthened.

[0022]

According to the decorative packaging material of the present invention, a pattern layer made of transparent yellow ink is provided on the back of a transparent plastic film.
A pattern layer made of synthetic resin ink, a transparent colored synthetic resin layer, and a metal-deposited film are laminated, and on the other hand, a matte synthetic resin layer is printed on the surface by using a reverse version of the pattern layer (negative printing plate). When the register is aligned and observed from the front side, the contrast is clearly visible through the transparent colored synthetic resin layer as a matte area with a metallic feeling due to metal deposition of the lower layer and a gold-like pattern layer area with metallic luster. It becomes a decorative packaging material that can be used. The mat synthetic resin layer is mixed with a white synthetic resin ink to significantly increase the adhesive strength to the base material, and the transparent synthetic resin layer to which a small amount of an appropriately selected coloring pigment is added to provide a pale color mat synthetic resin. The layer can be expressed, and a packaging material having an excellent decorative effect can be obtained.
