2. Description of the Related Art
Conventionally, single-sided polyethylene laminate (hereinafter abbreviated as polylaminate) paper is mainly used for moisture-proof packaging such as information paper. Polylaminate paper is widely used because it is easy to control the moisture proof by adjusting the thickness of the laminate and can be supplied at relatively low cost.

[0003] These papers that have been subjected to flat judgment processing are subjected to secondary processing such as cutting and punching, and are also set in a printing machine as they are in a stacked state, or cut to a standard size such as A4 or B4 (small judgment mode). ) Is used as a final product in office machines such as copiers and printers. However, with the recent increase in the use of these printers and office machines, supply from the stacking state has been increasing. There is a problem that the workability is reduced due to a paper feed failure such as a double feed occurring at the time of paper.

The occurrence of such double feeding has been improved from the aspect of the apparatus, but the coefficient of static friction between the sheets, especially on the stacking surface between different books (between the books), has been considered from the viewpoint of the sheets. It is clear that this is due to a decrease in the coefficient of static friction. Japanese Patent Laid-Open No. 2-127 discloses a method for reducing the static friction coefficient between the volumes.
Japanese Patent Publication No. 042/042 proposes a wrapping paper in which the resin used in the polysand type is specified, and Japanese Patent Application Laid-Open No. Hei 5-42961 proposes a wrapping paper in which the resin used in the polylami paper is specified. It is said that a preventive effect can be obtained.

[0005] On the other hand, in response to increasing public opinion in recent years such as resource protection and promotion of recycling, these conventional moisture-proof wrapping papers are all obstacles when laminating resin is used for deinking and recycling pulp after recovery of used paper. I couldn't respond. Therefore, the development of a wrapping paper that can be recycled and pulped has been proposed (Japanese Patent Publication No. 63-39022, Japanese Patent Application Laid-Open No. 3-2).
79492, JP-A-8-144192, etc.) and some renewable moisture-proof wrapping papers have already been put on the market.

However, most of these moisture-proof wrapping papers are used for winding up such as newsprint and continuous slip paper, etc., and are used as they are after finishing.
Many papers are not suitable for use in small-size paper cutting such as C paper, and even if they can be used, they do not have sufficient moisture-proof properties, or they have a coefficient of static friction due to the effects of chemicals used in the moisture-proof layer. As a result, there is a drawback that the above-described paper feed failure is likely to occur.

That is, in the conventional renewable moisture-proof wrapping paper, a moisture-proofing agent such as a wax emulsion or an acrylic resin is applied to a base paper such as unbleached or bleached kraft paper by a coating machine such as an air knife coater or a blade coater. The structure of these moisture barriers has a corresponding mechanical strength,
It is practically useful as a moisture-proof paper for wound products.
When used for plain paper (especially small paper) such as C paper, the static friction coefficient of the surface that comes in contact with the wrapping paper is reduced, and when set in a copying machine or the like, a paper feed failure such as double feeding may occur. In addition to the tendency to occur, there is a disadvantage that the moisture-proof performance is reduced after packaging by an automatic packaging machine, and that the product moisture increases.

The present inventors have pursued the causes of these obstacles. As for the decrease in the coefficient of static friction, the wax and resin components contained in the moisture-proof layer penetrate into the paper in contact and transfer due to friction. In particular, if the static friction coefficient between paper sheets drops to less than about 80% of the static friction coefficient between paper sheets that do not come into contact with the wrapping paper, and the decrease in moisture resistance is caused by the robustness of the applied moisture barrier layer itself Although it depends on the degree, it was found that the folded portion of the wrapping paper was rubbed by the corners of the paper product as a result of vibration during transportation after the packaging, and the moisture-proof layer was scraped off.

That is, these moisture-proof layers emphasize the effect of pulverized and regenerated pulping in the recovery of waste paper after use. Therefore, the moisture-proof layers are made of resin used for moisture-proof layers of conventional moisture-proof papers such as polyethylene and polypropylene. By comparison, the coating film is not robust, and it is not preferable in terms of penetration of wax and resin, but in the packaging of surrounding paper, which is a main application in the past, the outermost layer paper is not usually used, Since the wrapping paper was used several times, the reduction of the coefficient of static friction of the wrapped paper and the reduction of the moisture permeability at the part in contact with the wrapped paper were not very problematic, and no effective solution was proposed. . Therefore, as a result of various studies on methods for maintaining the performance of the moisture-proof layer and suppressing penetration of components such as wax that lower the coefficient of static friction, a barrier layer made of a water-soluble resin or a water-soluble polymer was brought into contact with the moisture-proof layer and the product. The present inventors have found that the problem of reduction in the coefficient of static friction can be improved by sandwiching between the base paper on the side and the present invention.

That is, in the present invention, infiltration of the wax component and the resin component is blocked by the barrier layer, and the moisture-proof layer is protected by forming the base paper into two front and back sides, and at the same time, the paper to be wrapped is protected. Separate the moisture barrier and barrier layers.
This prevents problems such as a decrease in the coefficient of friction and a decrease in moisture-proof performance caused by direct contact between the product and the moisture-proof chemical,
In addition, it is possible to make pulp from disaggregated and recycled paper after collecting waste paper. If the barrier layer is omitted and the base paper after the formation of the moisture-proof layer and the front and back sheets are simply used, the wax and resin components penetrate during long-term storage after production, and the friction coefficient of the wrapped paper gradually decreases. I do.

No. 5 has been proposed. However, although the former is not suitable for pulverization and regeneration pulping, and the latter has pulverization properties, the paper friction coefficient decreases due to penetration of the resin during storage, and a double feed trouble occurs. The materials used in the present invention will be described below.

The base paper may be subjected to surface coating equipment such as a size press, a gate roll, a shim sizer or the like to impart sizing properties, dyeing, or pigment coating within a range that does not impair the properties of the moisture-proof layer and the barrier layer. It is also possible to impart arbitrary characteristics by performing the above. As the raw material pulp, in addition to wood pulp such as kraft pulp (KP) and mechanical pulp (MP), natural non-wood pulp such as kenaf pulp and bagasse pulp, and deinked regenerated pulp (DIP) can be used as appropriate. Although it is possible, it is desirable not to use different kinds of fibers such as glass fibers and aramid fibers which hinder the pulverization / recycling pulping.
