Description of the Related Art Conventionally, in order to prevent moisture absorption or water absorption of contents, a polyolefin polymer compound such as polyethylene or polypropylene having excellent moisture resistance and water resistance is used for a paper support for packaging industrial products. Laminated polyolefin-laminated paper (hereinafter referred to as poly-laminated paper) has been used.
In particular, kraft paper laminated with polyethylene with low moisture permeability is used for wrapping paper for printing paper, art paper, and coated paper for the packaging of paper whose quality fluctuates due to changes in environmental humidity, especially among industrial products. It is used in large quantities as flat paper wrapping paper.

ていた。[0003] However, such a polyethylene laminated paper is inferior in disintegration due to a strong coating layer. That is, even if the used paper is recovered and used after use, in the production process of the recycled paper, there is a problem that the coating itself remains in a large sheet shape, and the shredded material is fused to a cylinder dryer or the like. . Therefore, polylami paper cannot practically be used as waste paper, and after use, it is almost always incinerated as industrial waste. On the other hand, wax-based moisture-proof paper utilizing the water repellency of paraffin wax, and pigment-based moisture-proof paper invented by the present inventors,
Since the moisture-proof coating layer is easily decomposed by an existing disintegration device such as a pulper, it is an easily disintegratable (recycle type) moisture-proof paper that can be sufficiently used as a raw material for recycled paper. However, after these easily disintegrating moisture-proof papers have been used, if it is not easy to determine that the moisture-proof paper is not the above-mentioned poly-laminate paper but is an easily disintegrating moisture-proof paper, the moisture-proof paper is collected and used paper is recovered. It is not known whether it can be used as waste and may eventually be treated as industrial waste. At the same time, in order to avoid troubles caused by mixing of poly-laminate paper in the process of manufacturing recycled paper from used paper, it has been necessary to be able to easily determine whether or not the moisture-proof paper is easily disintegrated.

ましい。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
In the present invention, as a method of coloring the paper support, dyeing and / or pigmenting (hereinafter, both dyes and pigments) can be used at any position while the paper support is running continuously, such as a paper making process and a rewinding process of the paper support. A method of coloring a paper support in a continuous line by spraying droplets, or a method of linearly coloring using a jig such as felt filled with a colorant liquid, etc. Is mentioned. At this time, a drying device for drying the solution or dispersion of the coloring agent may be particularly provided, but the coloring device is installed immediately before the drying device already provided in the paper machine or the coating machine for the moisture-proof layer. It is desirable. When coloring is performed in the paper making process, the water content of the paper is 60%.
By providing the coloring step before and after the press roll and before and after the size press device, the coloring agent bleeds moderately, and at first glance, an effect different from ordinary printing is obtained. This is particularly preferable because it allows the user to recognize at a glance that it is a disintegrating moisture-proof paper.

The position of the colored portion by the colorant may be adjusted in consideration of the paper width of the final packaging unit in the entire width of the paper making so that at least a part remains in the final packaging unit. The width to be colored may be any width that can be visually identified.
It is preferably about mm to 100 mm.

好ましい。In order to spray a colorant onto a paper support in the present invention, a tube is connected to a tubular nozzle having a through hole,
A paper container is provided at the end of the paper support, and the paper support is colored in a continuous line using a device capable of ejecting a colorant liquid by applying an internal pressure to the inside of the container. The form of coloring is not limited to a normal linear shape, but may be a broken line shape by intermittently ejecting the colorant liquid or a wavy line by moving the nozzle. In addition, it is also possible to color these lines in an arbitrary combination. In addition, although it is also possible to color using a jig (marker) such as felt filled with a colorant solution,
In this case, the running speed of the winding needs to be reduced because the colorant liquid may run out. Alternatively, coloring may be performed by immersing a part of a roll having a specific width in an ink container and bringing the roll into contact with a paper support. In addition, various colors of the coloring agent used for coloring can be selected, and a green-based color in which an image of environmental protection is being established is particularly preferable.

ましい。As the moisture-proof coating layer provided on the moisture-proof paper of the present invention, any material can be used as long as the moisture-proof coating layer can be easily decomposed by an existing used paper re-disintegrating device such as a pulper and used as a raw material for recycled paper. Although the wax-based moisture-proof paper may cause problems such as slipping of the recycled paper after slipping, a flat pigment such as phyllosilicate compound particles on a paper support proposed by the inventors of the present invention may be used. Moisture-proof paper provided with a moisture-proof layer containing a synthetic resin latex (JP-A-9-291499, Japanese Patent Application No. 9-2074487, etc.) is particularly preferred. When the moisture-proof layer is provided on one surface of the paper support, it may be provided on the same surface as the colored surface, or on the opposite surface,
It is desirable to apply the coating on the inner surface where the moisture-proof layer is in contact with the contents, and since the colored surface is easier to identify when it is outside the package, it is desirable to provide the moisture-proof layer on the opposite side to the colored surface.
