Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrapping paper composed of a laminated sheet, in particular, a reinforced wrapping paper which is made of paper as a whole and has a rich cushioning effect on the packaged product and improved tear strength. And its manufacturing method.

[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 it is tough, has excellent moisture resistance, and is inexpensive.

In this reinforced wrapping paper, two pieces of kraft paper are stuck together, and a bonding structure in which a synthetic resin mesh made of PP and PE is interposed at the bonding interface, or PP and PE are bonded at the bonding interface. It has a laminated structure with a synthetic resin film.

However, since these reinforced wrapping papers have a laminated structure in which a mesh made of a synthetic resin and a synthetic resin film are laminated, they have a problem that they are not recyclable and a problem that a harmful gas is generated during incineration. Improvement is an issue.

On the other hand, the applicant of the present invention is Japanese Patent Laid-Open No. 2001-233
No. 375 and Japanese Patent Application No. 2001-296924, a first paper sheet made of crepe paper, a second paper sheet made of the same, and a paper tape made of crepe paper are bonded to each other. Provided is a reinforced wrapping paper made of kraft paper, in which paper tapes are attached to each other at an interface so as to be interposed in parallel in the longitudinal direction and / or the lateral direction.

This reinforced wrapping paper is made entirely of paper without using the above mesh or film to achieve the reinforced purpose,
While having the advantage of being able to solve the problems in the above-mentioned conventional example and being able to enhance the cushioning effect by the above-mentioned crepe structure, the creped first paper sheet, the second paper sheet, and the paper tape When the three are bonded to each other via an adhesive, there is a problem that adhesion failure occurs in the valley of the crepe at the bonding interface, and then roll paper is wound, or the outer surface of the outer surface is compressed due to compression when the object is packaged. This causes problems such as crushing the crepe piles easily and diminishing the buffering effect.

[0007]

DISCLOSURE OF THE INVENTION The present invention appropriately solves the problems in the conventional example in which the above-mentioned synthetic resin mesh or synthetic resin film is interposed, and at the same time, JP-A-2001-23
To provide a reinforced wrapping paper and a method for producing the reinforced wrapping paper, which can appropriately achieve the buffering purpose and the tearing strengthening purpose in the reinforced wrapping paper proposed in No. 3375.

[0008]

This reinforced wrapping paper is made by bonding a first paper sheet and a second paper sheet with an adhesive, and making a paper at the bonding interface of the first and second paper sheets. The tape has a laminated structure in which the tape is laminated in the longitudinal direction and / or the lateral direction with the both sheets via an adhesive, and the reinforced wrapping paper is entirely creped in the laminated state.

As a method for producing the reinforced wrapping paper, a wrapping paper is prepared by pasting the first and second paper sheets and a paper tape together with an adhesive, and the wrapping paper is wetted. After compressing with a press roll and then peeling from the press roll using a doctor, the whole laminated packaging paper is creped at once. The crepe-wrapped wrapping paper is dried with a dryer and then wound as roll paper.

The reinforced wrapping paper has a structure in which the first and second paper sheets and the paper tape are bonded together with an adhesive,
Since the crepe is applied at one time, it effectively eliminates the adhesive failure of the valleys of each sheet and tape at the bonding interface, and each sheet and tape are creped while the crepes and valleys of the crepe are bonded to each other. It is firmly bonded and retains the crepe shape. Therefore, the crushing of the crepe against the compressive force when the roll paper is used or when the packaging object is packaged is effectively eliminated, and the cushioning purpose is appropriately achieved. In addition, it secures tear strength.

Further, the first paper sheet and the second paper sheet are bonded together with an adhesive, and a paper twisting string is longitudinally and / or laterally provided at the bonding interface of the first and second paper sheets. It has a laminated structure in which the both sheets are laminated with an adhesive material interposed therebetween in the direction, and in the laminated state, the entire reinforced packaging paper is temporarily creped.

As a method of manufacturing the above-mentioned reinforced wrapping paper, a wrapping paper prepared by pasting the above-mentioned first and second paper sheets and a paper twist string through an adhesive is prepared, and the pasting wrapping paper is wetted. Then, it is compressed with a press roll, and then peeled off from the press roll using a doctor to apply crepe to the whole laminated packaging paper at one time. The crepe-wrapped wrapping paper is dried with a dryer and then wound as roll paper.

The reinforced wrapping paper has a structure in which the first and second paper sheets and the paper twist string are bonded together with an adhesive,
Since the crepe is applied at one time, it effectively eliminates the adhesion failure between the sheets and the troughs of the twisted string at the bonding interface, and the sheets and the twisted strings are creped and bonded while the peaks and valleys of the crepe are bonded together. Securely adhered by the material to maintain the shape of the crepe. Therefore, the crushing of the crepe against the compressive force when the roll paper is used or when the packaging object is packaged is effectively eliminated, and the cushioning purpose is appropriately achieved. In addition, it secures tear strength.

Furthermore, the reinforced wrapping paper enables pollution-free incineration treatment and complete recycling (recycled paper recycling).

Are aligned with the edge portions 1'or / and 2'of the first paper sheet 1 and the second paper sheet 2, respectively, and the respective tapes are interposed,
Effectively prevent tearing of the reinforced wrapping paper from the ears.

The reinforced wrapping paper having the above-mentioned laminated structure is creped in the laminated state. As a result, the entire reinforced wrapping paper, that is, the laminated structure in which the crepes 1a, 2a and 3a are temporarily applied to the three parties 1, 2 and 3 or the crepes 1a, 2a and 3a to the four parties 1, 2, 3 and 4 ，
A bonded structure with 4a is provided. The extending directions of the crepes 1a, 2a, 3a, 4a are all the same.

As a method of manufacturing the above-mentioned reinforced wrapping paper, as shown in FIG. 3, a wrapping formed by bonding the first and second paper sheets 1 and 2 and the paper tapes 3 or 3 and 4 with an adhesive material. A method of preparing paper, wetting the laminated wrapping paper, compressing it with a press roll 11, and then peeling it from the press roll 11 using a doctor 13 to apply the crepes 1a to 4a to the entire laminated wrapping paper at one time. Take.

A specific example will be described in detail. As shown in FIG. 3, an adhesive is applied to the inner surface of the sheet 1 by the gluing device 5 while the first paper sheet 1 is unrolled from the base paper roll. Similarly, in synchronism with this, while the second paper sheet 2 is unwound from the base paper roll, an adhesive is applied to the inner surface of the sheet 2 by the gluing device 6, and the two paper sheets 1 and 2 are bonded together by a press roll 7 Then, the paper is passed through and pressure is applied, and the sheets are bonded together via the above adhesive.

On the other hand, on the inlet side of the laminating press roll 7, a supply unit for the paper tape 3 or 3, 4 is arranged between the first and second paper sheets 1 and 2, and the paper tape 3 While unrolling the paper tape 3 or 3, 4, the above-mentioned first and second paper sheets 1, 2 in the bonding press roll 7
Intervening in the meantime, passing through the bonding press roll 7,
First and second paper sheets 1, 2 and paper tape 3 or 3, 4
