DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strip-shaped adhesive sheet material composed of two upper and lower sheet substrates attached by a plurality of strip-shaped adhesives. The present invention relates to wrapping paper used for wrapping paper and the like.

[0002]

2. Description of the Related Art Conventionally, in order to manufacture a strip-like bonded sheet material composed of two upper and lower sheet base materials bonded by a plurality of strip-shaped adhesives,
There is a method called hot-melt coater method, in which a hot-melt adhesive made of a thermoplastic resin is placed in an applicator called an applicator at intervals in the width direction of the sheet base material. There is a method in which a hot-melt adhesive is heated and melted, and in a molten state, the adhesive is applied in a striped shape on a base material sheet by an applicator, and the upper and lower two sheets are pressed and adhered.

[0003] The sheet base material thus coated with the adhesive in a striped manner and adhered thereto is lower than the case where the adhesive is applied to the entire surface and the upper and lower two sheet base materials are adhered. Since it is not bulky and easy to bend (fold) at the time of packaging, it is used, for example, for coiled steel wrapping paper.

[0004]

However, in this case,
In the case where the sheet base material after the pressure bonding is applied, or in the case where it is wound on a roll, for example, air (air) exists in a portion between the stripe-shaped adhesive application areas, and the air escapes. Since there was no portion, it was easy to wrinkle, and because of the presence of air, it was hard, bulky, and very difficult to wind up on a roll.

[0005] In view of such circumstances, the present invention easily removes air (air) existing in a portion between the stripe-shaped adhesive application areas, is less likely to wrinkle, is soft, is not bulky, and is wound around a roll. It is an object of the present invention to provide a striped adhesive sheet material that is made up of two upper and lower sheet substrates attached by a plurality of adhesives applied in a stripe shape.

[0006]

SUMMARY OF THE INVENTION A striped adhesive sheet material according to the present invention has been made in order to achieve the above objects and objects, and has the following (1) to (6). It is assumed that.

(1) A strip-shaped adhesive sheet material composed of two upper and lower sheet substrates adhered by a plurality of strip-shaped adhesives, wherein And a strip-shaped adhesive sheet material provided with an adhesive missing portion.

(2) The striped adhesive sheet material according to the above (1), wherein the adhesive missing portion is provided at a zigzag position when viewed from the upper surface of the sheet.

(3) The striped adhesive sheet material according to the above (1), wherein the adhesive missing portion is provided at a corrugated position as viewed from the upper surface of the sheet.

(4) The strip-shaped adhesive sheet material according to the above (1), wherein the adhesive missing portion is provided at a V-shaped position as viewed from the upper surface of the sheet.

(5) The strip-shaped adhesive sheet material according to the above (1), wherein the adhesive missing portion is provided at a quadratic curved position as viewed from the upper surface of the sheet.

(6) The striped adhesive sheet material according to the above (1), wherein the adhesive missing portion is provided at an arcuate position as viewed from the upper surface of the sheet.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an enlarged perspective view of a first embodiment of the striped adhesive sheet material of the present invention, and FIG. 2 is a top view thereof. In the figure, reference numeral 10 denotes a striped adhesive sheet material of the present invention, and the sheet material 10 is composed of two upper and lower sheet materials.
12 and 14 are pressure-bonded through hot-melt adhesive application areas 16 and 16 provided by applying a plurality of rows in the longitudinal direction. Then, adhesive missing portions 18 are provided at zigzag positions indicated by imaginary lines A in FIG. 2, respectively. In this case, a method called a hot melt coater method is used as a method of providing such adhesive missing portions 18 and 18, and this method uses a hot melt adhesive made of a thermoplastic resin with an applicator called an applicator. The hot melt adhesive is heated and melted in an applicator, and the adhesive is applied in a striped manner to the base sheet using the applicator in the molten state. This is a method in which the upper and lower two sheets are pressed and adhered, and this can be performed by shifting the timing of this coating machine by a predetermined time and then turning it on and off.

In this case, the hot melt adhesive is not particularly limited, and can be changed according to the types of the upper and lower two base sheets to be stuck.
For example, an EVA-based adhesive may be used. The upper and lower sheet bases are not limited at all. For example, in the case of wrapping paper for steel, “PET (9 μm
) / Kamimi Net (Woven in 2cm square, 2cm square) / PE (20μm) / Kraft paper (75g basis weight) / PE (20μm
) / PE cloth (number of yarns to be driven: number of yarns in one inch, 6 (vertical) x 6 (horizontal)) "and" PP (20 μm) / PE cloth (number of yarns to be driven: number of yarns in one inch, 6 (vertical) × 6 (horizontal)) / PP (20 μm) ”may be attached using a hot melt adhesive.

As described above, the hot melt adhesive application areas 16, 16 provided by applying a plurality of rows in the longitudinal direction are provided.
In addition, since the adhesive missing portions 18 are provided at the zigzag positions indicated by the imaginary lines in FIG. 2, air existing in the spaces 19 between the adhesive application regions 16 and 16 is removed. ,
When sticking the sheet base material, when using as a wrapping paper or winding, etc., air (air) existing in the portion between the stripe-shaped adhesive application areas via the adhesive missing portions 18, 18 Will come off easily.

FIG. 3 is a view similar to FIG. 2 showing a second embodiment of the striped adhesive sheet material of the present invention. The second embodiment is different from the first embodiment in that the adhesive missing portions 28 and 28 are provided at the corrugated positions indicated by the imaginary lines B, respectively.

FIG. 4 is a view similar to FIG. 2 showing a third embodiment of the striped adhesive sheet material of the present invention.
The third embodiment is different from the third embodiment in that the adhesive missing portions 38, 38 are provided at V-shaped positions indicated by the imaginary lines C, respectively.

FIG. 5 is a view similar to FIG. 2 showing a fourth embodiment of the striped adhesive sheet material of the present invention. The fourth embodiment is different from the fourth embodiment in that the adhesive missing portions 48 and 48 are provided at the positions of the quadratic curve shown by the imaginary line D, respectively.

FIG. 6 is a view similar to FIG. 2 showing a fifth embodiment of the striped adhesive sheet material of the present invention. In the fifth embodiment, the adhesive missing portions 58, 58 correspond to the virtual lines E, F.
Are provided at the arcuate positions shown in FIG.

[0021]

In the striped adhesive sheet material of the present invention having the above-mentioned structure, the striped adhesive sheet composed of the upper and lower two sheet substrates adhered by an adhesive applied in a plurality of stripes. In the adhesive sheet material, an adhesive missing portion is provided in the stripe-shaped adhesive applied area, so that when the sheet substrate is attached, it is used as a wrapping paper or when the adhesive is missing. The air (air) existing in the portion between the stripe-shaped adhesive application regions easily escapes through the portion, so that it is hard to wrinkle, soft, not bulky, and can be wound on a roll.
