Abstract

PROBLEM TO BE SOLVED: To improve the reproducibility of fine patterns, and to improve the appearance by assembling a plastic film of a blank which is formed by laminating the plastic film provided with a printed layer on a back side and punched to a specified shape on an outer surface side. SOLUTION: A laminate material to constitute a detergent carton comprises a plastic film 21, a printed layer 22, an adhesive layer 25, a paper layer 23, an adhesive layer 26 and a paper layer 24, and the adhesive layers 25, 26 consist of either one kind of a dry laminate adhesive, a wet laminate adhesive, or a molten resin. The plastic film 21 is formed of an oriented film consisting of polyethylene terephthalate, polypropylene, and polyamide. These materials are excellent in glossiness, transparency, mechanical strength and printing suitability, and the reproducibility of fine printing and appearance of the printed layer are improved. To give the metallic glossiness, an aluminum foil is laminated in addition to an aluminum deposition layer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a detergent carton having excellent surface gloss.

[0002]

2. Description of the Related Art A small paper carton for storing a powder detergent generally has a paper layer as a base material, a pattern layer made of a heat-drying type ink on the outside thereof, and an ultraviolet-curing varnish (hereinafter referred to as a UV varnish).
Is provided with a coating layer made of, and is implemented with a configuration excellent in glossiness and aesthetics. As described above, by providing a pattern layer made of a heat-drying type ink and a coating layer made of a UV varnish on the front side of the paper layer, a certain level of gloss can be obtained. However, it is difficult to produce a carton having higher gloss. there were. In addition, since the pattern layer and the coating layer are provided on the surface of the paper layer as the base material, ink transfer is poor due to the problem of the smoothness of the surface of the paper layer, poor reproducibility of fine patterns, and improvement of cosmetics. There were restrictions.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a detergent carton having a reproducibility of a fine pattern, a good gloss, and an excellent cosmetic appearance.

[0004]

According to the present invention, a laminated material, in which a plastic film having a printed layer provided on the back side via an adhesive layer on the outside of a base material mainly composed of a paper layer, is punched into a predetermined shape. A detergent carton, characterized in that the bangs are assembled with the plastic film facing outward. The invention according to claim 2 is the detergent carton, wherein the plastic film is made of a stretched plastic film. The invention according to claim 3 is the detergent carton, wherein the adhesive layer is made of any one of a dry laminate adhesive, a wet laminate adhesive, and a molten resin.

[0005]

FIG. 1 is a sectional view of a laminated material constituting a detergent carton of the present invention. As shown in FIG. 1, the laminated material constituting the detergent carton has a configuration of plastic film 21 / printed layer 22 / adhesive layer 25 / paper layer 23 / adhesive layer 26 / paper layer 24. 26
The layer 20 is made of any one of a dry laminating adhesive, a wet laminating adhesive, and a molten resin.

Further, as shown in FIG. 2, a plastic film 21 / printing layer 22 / adhesive layer 25 / aluminum deposited layer 33 / adhesive layer 25 / paper layer 23 / adhesive layer 26 / paper layer 2
4 may be adopted.

Here, the paper layers 23 and 24 may have any thickness as long as they can maintain the strength and the like as a detergent carton. Specifically, the total thickness of the paper layers 23 and 24 is 220 to 700.
A range of g / m ² is preferred. The paper layer is paper layer 2
In addition to the two-layer structure of 3, 24, a single layer having the above-mentioned thickness may be used.

As the plastic film 21, a stretched film of polyethylene terephthalate (PET), polypropylene (OPP), polyamide (ONy) or the like can be used. These films are glossy,
It is excellent in transparency, mechanical strength, and printability, and increases the reproducibility of fine printing and the aesthetics of the provided printing layer.
Further, in order to impart metallic luster, an aluminum foil may be laminated instead of providing an aluminum vapor-deposited layer. The thickness of the aluminum foil may be 7 μm or more.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is an example of a specific laminated structure used for a detergent carton. Configuration Example 1: PET film (12 μm) / printing layer / SP
E (15 μm) / paper layer (350 g / m ² ) Structural example 2: PET film (12 μm) / print layer / adhesive layer / paper layer (350 g / m ² ) The adhesive layer is a two-component curing type for dry lamination. The application amount was 4.5 g / m ² with a urethane-based adhesive. Compared to providing a printing layer on the paper surface, the surface smoothness is excellent, so the ink transfer is good, so there is no dropout of halftone dots, and the detergent has been printed with excellent reproducibility. Could be with carton.

[0010]

According to the present invention, since a stretched film having a printed layer on the back surface is used as the outermost layer, a detergent carton with good reproducibility of fine printed layers can be obtained, and cosmetics can be obtained because scratches are not easily formed. Can be kept. In addition, by combining the printing layer and the vapor deposition layer,
A detergent carton having a metallic luster was obtained, and could be distinguished from other commodities.
