DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrapping paper made of a laminated sheet such as kraft paper, and more particularly to a reinforced structure in the laminated wrapping paper.

[0002]

2. Description of the Related Art Conventionally, as wrapping paper for various industrial products,
Reinforced wrapping paper using kraft paper is often used because of its toughness, excellent moisture resistance, and low cost.

[0003] Conventional reinforced wrapping paper has two kraft papers bonded together and a bonding structure in which a synthetic resin mesh made of PP and PE is interposed at the bonding interface, or at the bonding interface. It has a bonding structure in which a synthetic resin film made of PP and PE is interposed.

[0004]

However, since these reinforced wrapping papers have a laminated structure in which a mesh or film made of synthetic resin is sandwiched, the point of lack of recyclability is pointed out as the biggest problem. It has become. Further, the conventional reinforced wrapping paper has a problem that harmful gas is generated during the incineration treatment.

The present invention is to provide a reinforced wrapping paper which appropriately solves the above-mentioned problems in the prior art while securing the purpose of strengthening the reinforced wrapping paper.

[0006]

In this reinforced wrapping paper, a first paper sheet and a second paper sheet represented by kraft paper are bonded together, and a bonding interface between the first and second paper sheets is provided. In this case, a paper tape made of the same kraft paper or the like is attached in parallel at intervals. Therefore, while achieving complete recycling, the purpose of strengthening was also achieved.

Further, crepe paper is applied as a paper tape interposed at the bonding interface between the first and second paper sheets,
The above-mentioned recyclability is also provided while enriching the buffer action. The paper at the most parallel end in the paper tape interposed in parallel.
The tape made from the edge of the tape and the first and second paper sheets
Of the ear so that it matches the edge of the ear.
Effectively prevent tearing of the wrapping paper from the ear. Again
Fold the paper tape in two in the longitudinal direction
The bonding interface between the first paper sheet and the second paper sheet
For the purpose of strengthening with the paper tape.
Up.

The reinforced wrapping paper uses kraft paper for the first paper sheet and the second paper sheet, and the same kraft paper is used for the flat tape or crepe paper. The reinforcement purpose and the recycling purpose were achieved while utilizing the above characteristics.

Further, the first paper sheet and / or the second paper sheet is formed of a transparent or translucent, for example, glassine paper or the like which can see through the paper tape, and the printing on the surface of the paper tape is visually recognized through the sheet. I was able to do it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a first paper sheet 1 made of kraft paper and a second paper sheet 1 made of kraft paper are shown.
A paper sheet 2 is prepared, a paper tape 3 made of kraft paper is interposed between the first and second paper sheets in parallel, and the three members are bonded to each other via an adhesive.

As a result, as shown in FIG. 2, paper tapes 3 made of the same kraft paper are interposed in parallel at intervals at the bonding interface between the first and second paper sheets 1 and 2 made of kraft paper. To form a reinforced wrapping paper having a laminated structure.

The first and second paper sheets 1 and 2 and the paper tape 3 forming the reinforced wrapping paper are all made of paper (made of pulp) and can be completely recycled. Achieve reinforcement objectives while making the best use of them.

Preferably, the most parallel end of the paper tape 3 in the paper tape 3 is a first tape or a second tape, as shown in FIGS.
The edge of the paper sheet 1, 2 is interposed so that the edge 5 of the paper tape 1 and the edge 6 of the paper tape 1 coincide with the edge 5. This effectively prevents the reinforced wrapper from tearing from the ears.

As shown in FIG. 3, a paper tape 3 interposed at the bonding interface between the first and second paper sheets 1 and 2 is provided.
In addition to flat tape made of kraft paper, crepe paper 3 '(wrinkled paper) made of kraft paper is applied, and the above-mentioned recyclability is also provided while enhancing the buffering action. The wrinkled shape of the crepe paper is given at the time of paper making or after the paper making by a known method, and the paper kraft paper is slit into a tape and applied.

As shown in FIG. 4, the first paper sheet 1 and / or the second paper sheet 2 is formed of a transparent or translucent paper sheet through which the paper tape 3 can be seen. The print 4 applied to the surface of 3 is made visible through sheet 1 and / or 2. The print 4 is a character, a graphic, a pattern, etc., and selects a print intended for the user's visual effect.
Protect this print with a sheet.

FIG. 5 shows a state in which the flat tape or the wrinkled tape forming the paper tape 3 is folded in two or S-shaped in the longitudinal direction so that the first paper sheet 1 and the second paper sheet 2 are adhered to each other. 5 shows a reinforced wrapper interposed at the mating interface. This reinforced wrapping paper significantly enhances the purpose of reinforcement by the paper tape 3.

The first and second paper sheets 1 and 2 and the paper tape 3 may be made of other papers having an appropriate property according to the intended use, in addition to kraft paper.

[0018]

As described above, the reinforced wrapping paper can achieve the purpose of complete recycling while achieving the purpose of the reinforcing structure of the wrapping paper, and can provide a reinforced wrapping paper utilizing the advantages of the reinforced kraft wrapping paper.
