Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative printing paperboard material made by pasting a printing surface and paperboard on one side of a transparent plastic film.

Conventionally, when beautiful printing is required, such as on magazine covers or cake boxes, after offset printing or gravure printing is performed on the surface of paperboard, vinyl processing, press processing, or film lamination processing is used to protect the printed surface. was being carried out.

However, in both cases, although the printed surface is protected and the gloss is improved, since printing is performed on the surface of the paperboard, the printing ink is absorbed by the paperboard (hereinafter referred to as ink sinking), compared to printing on film. However, it was inevitable that the printing effect would be inferior.

The present invention improves the above-mentioned drawback that when printing on the surface of paperboard, the printing effect is poor due to sinking of ink, and prints characters and designs on one side of a transparent plastic film.
Cosmetic printing board that ensures normal printing (letters and designs are not reversed) when viewed through the plastic film, and then glues the printed surface to the paperboard to prevent printing ink from sinking. Suggest materials.

The configuration of the present invention will be described below with reference to drawings related to embodiments thereof.

FIGS. 1 and 2 show conventional paperboard materials for decorative printing.

Figure 1 shows the printed paperboard 3, which is coated with an adhesive 4 after applying a layer of printing ink 2 to the plastic film 1, and is bonded to the printed paperboard 3. Figure 2 shows the printed paperboard 3. However, after providing a layer of printing ink 2, vinyl processing 5 was performed.

The paperboard shown in Figures 1 and 2 is a conventionally known example, and the paperboard used for this is printed directly on the paperboard, so the printing effect is improved and the sinking of ink is minimized. For this purpose, paperboard coated with clay (coated ball) is generally used.

FIG. 3 shows an embodiment of the present invention, in which printing is performed on a plastic film 1, adhesive 4 is applied to two sides of the printing ink, and paperboard 3 is coated with adhesive 4.
Paste with.

Since printing is performed on the plastic film 1, there is no sinking of the printing ink 2 compared to printing on the paperboard 3, and beautiful printing is possible.

Also, regarding the paperboard used, ordinary paperboard (uncoated board) can be used instead of one with a surface coating (coated board), and decorative printing can be easily performed.

It is a decorative printing paperboard material that is clearly better than the conventionally used paperboard material with a surface coating (coated ball) and vinyl processing or lamination with a plastic film.

The plastic film used in the present invention may be any film such as vinyl chloride, polypropylene, polyester, and nylon.

In the case of a polyolefin film, at least one side to be printed is corona treated, and when laminated together as a paper carton, both sides are desirably corona treated.

As for adhesives for laminating plastic films and paperboard and adhesives for laminating paper containers, vinyl acetate-based, ethylene-vinyl acetate-based, acrylic-based, rubber-based, urethane-based adhesives, etc. can be used. Adhesives must be selected depending on the type of plastic film.
