DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file having cotton or the like adhered to the surface thereof, and a heading such as a file made of cloth attached to a cover of a cloth such as a binder or a note as a heading or a pocket.

[0002]

2. Description of the Related Art Conventionally, a cover made of paper, such as a file, a binder, and a note, is provided with a label coated with a commercially available glue or various adhesives. Is attached with a head made of PVC film that is heat-sealed by high-frequency heating using the property of high dielectric constant, and a polypropylene cover is heat-sealed with polypropylene film by a heater or ultrasonic heating. Although a headline to be worn is attached, a small frame fitting is attached to a cloth cover, and paper is put in the metal cover and used as a heading.

[0003]

However, even if it is attempted to attach a heading to a cloth cover in the same manner as to attach it to a paper, vinyl chloride or polypropylene cover, the cloth is meshed. For this reason, labels that have been coated with an adhesive or the like have low adhesive strength and cannot withstand use.In addition, headlines that can be attached to the front cover are originally transparent or translucent, and have a certain level of waist strength. It is desirable to have a strong bond that can be strongly adhered to the cover surface, has hinge characteristics that can be closed and opened, and can be easily adhered without tearing from the adhesive part and peeling off, but it satisfies them It is impossible to attach a heading that can be attached to a cloth cover using a conventional method.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve such a problem and make it possible to carry out the heading effectively such as a cloth file. A transparent or semi-transparent laminating film obtained by laminating a hot-melt adhesive such as an adhesive nylon is attached to one side of a cloth cover such as a file by heating and pressing.

[0005]

Therefore, a base film such as polyester, nylon, or polyolefin film, an adhesive nylon or an adhesive polyester. The softening point of the hot melt adhesive is about 40 ° C. to 100 ° C. and the melting point is about 60 ° C. to 150 ° C. in combination with the olefin-based hot melt adhesive. When pressed, it can penetrate well into the cloth structure of the cloth and can be strongly bonded, and the hot melt adhesive has a rigidity (stiffness kg / cm ² ) of 200 to 15 mm.
00, tensile strength (kg / cm ² ) 100 to 1500,
Since the elongation (%) is 300 to 800, it is strong as a hot-melt adhesive film, elastic and strong in hinge, and adheres well to a base film or cloth of polyester or the like even at room temperature, and tears. Even if it does not come off easily, even if it comes off once, it can be used again by heating and bonding, and as a base film such as polyester, it has high tensile strength, rigidity and high melting point, so it is possible to fuse the film The interface is also improved in rupture resistance, and the film can be smoothly fed out, so that the hinge property is enhanced, the bending property is improved, and transparent or translucent headings can be effectively attached.

[0006]

Next, an embodiment of the present invention will be described.
INDUSTRIAL APPLICABILITY The heading according to the present invention can be strongly adhered to the mesh structure of a cloth cover of a cloth cover or the fiber structure which is a collection of fine threads, and is transparent or translucent, and has a certain degree of stiffness. It has a hinge characteristic that can withstand opening and closing of the cover, and can be easily adhered even if it is peeled off without tearing from the heat-sealed portion.

For this reason, hot melt adhesives such as nylon-based, polyolefin-based, polyester-based, polyurethane-based and rubber-based adhesives having a softening point of about 40 ° C. or more are used, and the thickness of the adhesive becomes 10 μm or more. A hot-melt adhesive laminating film having a thickness of about 30 to 100 μm having a hot-melt adhesive layer, and a base film of a film such as polyester, nylon, polypropylene, vinyl chloride, vinylidene chloride, etc. In addition, the base film of nylon, polyester, etc., has 20,000 cycles of the synergistic effect between the strength and flexibility of properties such as tensile strength and tensile strength, and the correlation between the adhesive strength and flexibility of hot melt adhesives. It is able to withstand the opening and closing of the cover as described above, and it is easy to tear the heat-sealed interface of the film. By using a film having a high melting point and high tensile strength, such as iron, as the base film, the thickness and characteristics of the base film do not change even when the hot melt adhesive layer is melted, thereby solving the problem.

FIG. 1 shows a first embodiment. In the case of laminating film 1, polyester is 50 microns, polyethylene is 40 microns, and ethylene-vinyl acetate copolymer resin is 30 microns. Softening point is 60
A three-layer laminating film having a melting point of 120 ° C. at 120 ° C., and the laminating film 1 is made of a cotton file note 2
, And both ends 1a and 1b are heat-sealed to the outer surfaces of the front cover 2b and the back cover 2c at a temperature of 120 ° C. and a compression time of 1 second, respectively. By inserting paper on which a name or a pattern is printed, the spine of the cotton file knot 2 can be attached, but the adhesive force between the laminating film 1 and the cloth is 8.0.
00g / 25mm, sufficiently adhered firmly.
Both end portions 1a and 1b, which are contact interfaces between the film 1 and the cloth
Has a tear strength of 4 kg / cm, which is very strong. Even if the cover of the cotton file knot 2 is opened and closed 20,000 times, the laminating film 1 does not tear and does not peel off from the cloth surface. Further, even if the laminating film 1 is peeled off from the cloth surface with a strong external pressure, the laminating film 1 may be removed with a household iron or the like.
When the heat bonding is carried out at 2 ° C. for 2 seconds, the film can be sufficiently bonded to the cloth.

[0009]

[0010]

As described above, according to the present invention, a transparent or translucent laminating film obtained by laminating a hot-melt adhesive such as adhesive nylon on one side of a base film such as polyester is made of a cloth such as a file. By applying heat and pressure to the cover, headings such as headings and pockets can be attached to the cover of a cloth file, etc., the breakage resistance of the fusion interface of the film is improved, and the film can be sent out smoothly. The hinges are strong, the bendability is also improved, and the headings can be effectively attached to the front surface of a cloth file or the like that has not been seen conventionally, and it has a feature that can be suitably implemented. .
