Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a highly glossy carton paper, which is among high-grade carton papers, and which has a glossy metallic luster.

Conventional 9 High Gloss Cult/Paper: In order to obtain a metallic luster, as shown in Figure 1, aluminum foil (7 to 20μ) (2
) are laminated via adhesive (3), the aluminum surface is decorated with printing, etc., and a printed colored layer (4) is applied, then p, p, o, p, s, p, v, It was common to laminate a hard film (15-20μ) (5).

As described above, the characteristics of conventional carton paper are that the printing ink does not stick well to the aluminum foil surface of the carton paper, and when laminating a film on the surface after printing, the surface gloss of the carton paper cannot be obtained sufficiently. There is a concern that air bubbles may occur due to lamination, and in paper laminated structures,
There were problems such as low abrasion resistance and poor suitability for bonding and bonding during box manufacturing.

The carton paper of the present invention can be manufactured by a simple method, and its workmanship quality has been further improved.
Using PET, P, P film, etc. with an easily adhesive layer,
By performing aluminum vapor deposition and laminating this onto paperboard, it is possible to create cult paper with better quality and lamination strength at a lower cost than conventional high-gloss cult paper. Therefore, one of the key points in carton production is that it must be possible to bond by sack bonding (emulsion adhesive).
This problem can be solved by creating a vapor-deposited film with an easily adhesive layer on its surface and using it as a laminated material as carton paper.

The gist of the present invention is to provide an anchor coat layer for metal vapor deposition on one side of a plastic film having an excellent adhesive surface such as polypropylene, a metal vapor deposited layer on the coat layer by a vapor deposition method, and ink adhesion to the side of the vapor deposited layer. This is a strong gloss cult paper made by providing a corona discharge treatment layer on the other side of the plastic film as an auxiliary layer and bonding it to a paperboard base material via an adhesive. Form an anchor coat layer for vapor deposition.

After forming a metal vapor deposited layer by a vapor deposition method, forming a solid or pattern colored printing layer on the side of the deposited layer via an ink adhesion auxiliary layer, and forming a corona discharge treatment layer on the other side of the film, 1.
This is a method for producing a highly glossy carton paper, characterized in that the rolled paperboard base material and the treated layer side are dry laminated via an adhesive.

The laminated structure of the carton paper of the present invention will be explained in detail according to the embodiment shown in FIG. Anchor coat layer α1. Plastic film layer (6), corona treatment layer 01) treated on the surface of the film layer, dry lamination adhesive N Oz, 31
09/- It has a laminated structure consisting of a paperboard base material (9).

The carton paper of the present invention is produced by forming an anchor coat layer 00 for metal deposition using a coater on the negative side of a winding film (6) made of polypropylene, etc., and using a vapor deposition method to form a metal deposition layer (8).
) is formed, and an ink adhesion auxiliary layer 03 is formed as an anchor coat layer for adhesion and printing on the vapor deposited layer (8) side, and a solid or pattern colored printing layer (7) is applied.

Next, a corona discharge treatment layer α℃ is formed on the other side of the film.
The paperboard base material αQ is heated and dry laminated via adhesive@.

The carton paper of the present invention is made by depositing aluminum on a film such as polypropylene, laminating it on a paperboard, coating the aluminum deposition surface with an auxiliary layer for easy adhesion, and then applying a printing layer to the auxiliary layer. Some carton papers are not laminated with a film for easy adhesion on the outermost surface, so there is no need to worry about air bubbles caused by film lamination due to residual drying powder during the printing process, and sufficient carton lamination strength is obtained. To obtain carton paper which is free of ruled line cracking during grain processing, has good adhesion and tone reproducibility of printing ink to the vapor-deposited layer side, has good adhesion suitability for sack attachment in box making, and has a colored luster due to the metal vapor-deposited layer of the carton paper. I can do it.
