Field of the Invention The present invention relates to a renewable moisture-proof paper, and more particularly, to a packaged material, for example, when used as a wrapping paper, by transferring a wax component or the like contained in a moisture-proof layer to the packaged material. The present invention relates to a renewable moisture-proof paper, a method for producing the same, and a wrapping paper, which prevent deterioration of the quality of the paper.

サイクルを不可能にしている。2. Description of the Related Art Moisture-proof paper is generally made of polyethylene,
Those coated with an olefin resin such as polypropylene are well known and widely used. The moisture-proof paper coated with the olefin-based resin is excellent in moisture-proof property, good in workability, inexpensive, and very excellent as moisture-proof paper. However, on the other hand, from the viewpoint of recyclability, that is, from the viewpoint of recycling waste paper, since the coating strength of the moisture-proof layer is too strong, in the pulper used in the process of regenerating and pulping the paper, it was detached from the fiber part of the paper. The olefin-based resin layer remains as a lump or film without being finely dispersed, and adheres to the drying roll of the paper machine or adheres to the surface of the recycled paper, causing bleeding and irregularities, and recycling waste paper. Making it impossible.

う問題を含んでいる。[0003] In recent years, with the demand for recyclable moisture-proof paper, a moisture-proof paper coated with an emulsion composed of a synthetic rubber latex and a wax emulsion has been proposed. Although this moisture-proof paper has excellent moisture-proof properties and also has recyclability to waste paper, it has a problem of poor slip resistance.

る。[0004] On the other hand, the present inventors previously applied a hot melt composition containing a specific component in a specific ratio to a paper base material, so that it has excellent moisture-proof properties and has recyclability to waste paper. Have found that it is possible to provide an inexpensive moisture-proof paper with less slippage between the moisture-proof papers, and have already filed an application (Japanese Patent Application No. Hei 9 (1998) -197686).

(E) 1 to 7 parts by weight of a compatibilizer, [100 parts by weight in total of (A) to (E)] are applied to a paper base material, and the paper base is disintegratable and excellent in moisture resistance. This method has excellent moisture resistance and defibration properties, has no problem with respect to slip resistance, which has been regarded as a drawback of the emulsion type, and almost satisfies the characteristics required for renewable moisture-proof paper.

It is required to prevent the slip resistance caused by the transfer of the substance contained in the paper to the paper to be packaged, and to prevent the blocking that occurs when the packages are stacked many times.

望されていた。However, regarding such required properties, moisture-proof paper coated with the above-mentioned wax-containing emulsion is also a moisture-proof paper made of a hot melt composition proposed by the present inventors in Japanese Patent Application No. 9-344313. Paper is hardly satisfactory. In addition, these moisture-proof papers have a problem that they repel ink and have poor printability, and they are not suitable for wrapping paper. Thus, it is excellent in moisture resistance and disintegration, and there is no transfer of substances from the moisture-proof coating layer to the paper, the slip resistance of the paper in contact with the wrapping paper does not decrease, and even when the packages are stacked. There has been a demand for the development of renewable moisture-proof paper and wrapping paper that do not cause blocking.

１〜１０重量部程度が好ましい。In the present invention, the barrier coat layer functions to prevent substances contained in the moisture-proof layer from migrating out of the moisture-proof layer and to impart and improve printability.
For example, an acrylic resin, a vinylidene chloride-acrylic copolymer resin, a chlorinated polyolefin, a polyamide resin, a nitrified cotton resin, a phenol resin, a polyurethane resin and the like are suitable, and these are used alone or in combination of two or more. These may be used alone or in combination of two or more to form a plurality of layers. In addition, it is used in combination with inorganic substances such as silica, titanium dioxide, talc, kaolin, and calcium carbonate as additives, fatty acids or salts thereof, surfactants such as long-chain hydrocarbon paraffins and waxes to prevent slip. It is also possible to enhance the effect of preventing the property from decreasing and the effect of preventing blocking. However,
Since a large amount of paraffins and waxes reduce slip resistance and printability when used in a large amount, it is preferably about 1 to 10 parts by weight based on 100 parts by weight of the resin.

紙を提供することができる。As shown in Table 1, the moisture-proof paper having the barrier coat layer of the present invention (Examples 1 to 4) has a higher moisture permeability than the conventional moisture-proof paper without the barrier coat layer (Comparative Examples 1 and 2).
It is good with no change in disintegration, and prevents slippage of the paper to be wrapped due to migration of the moisture-proof layer-containing material, which is regarded as important in applications such as individual packaging of copy printing paper such as PPC and LPB. it can. Furthermore, conventional renewable moisture-proof paper has the disadvantage that blocking occurs and printing cannot be performed on the surface of the moisture-proof paper with aqueous ink.However, the moisture-proof paper having the barrier coat layer of the present invention eliminates those disadvantages. In addition, a renewable moisture-proof paper and a wrapping paper having excellent surface characteristics can be provided.
