Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crepe band.

[0002]

2. Description of the Related Art As an application of a band, there is, for example, a tag band. It is manufactured by making conventional tag paper and base paper in one or two layers by a circular paper machine and slitting it at a predetermined width.

[0003] When sealing a 10,000-yen bill in units of one million yen, a heat-sealable roll band having a width of 20 mm is used as a band, and a width of 4 mm is used for sealing a bundle of 10 million yen.
It is used in banks and the like as a 0 mm heat-sealing roll.

[0004]

However, since the conventional tag band paper has an elongation of less than 5%, especially in a heat-sealing roll large band or the like, the band breaks due to the volume of the sealed tag. There was a problem that easily occurred.

Therefore, it is conceivable that a crepe treatment is applied to the sash to increase the elongation, thereby improving the toughness and making the sash less likely to occur. However, since the crepe paper is creped by a dryer, the front and back surfaces of the base paper are wrinkled, and there is a problem that it is difficult to process the heat-sealable resin for heat-sealability. Furthermore, the name of a bank or other financial institution is printed or stamped on the non-resin-processed side, on which the heat-sealable resin is not applied, but the crepe is applied to the wrinkled paper. On the non-resin-processed surface side, there arises a new problem that good printing and imprinting cannot be performed. In addition, when creping is performed, the thickness increases, and when it is wound up in a roll, there is a problem that a long product cannot be formed.

[0006] An object of the present invention is to solve the above-mentioned problems and to provide crepe having appropriate elongation and printability by providing the surface with smoothness despite being creped. It is intended to provide attached paper.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a wrapping paper having a predetermined width is creped and at least one surface is smoothed. The essence of the invention is a crepe band.

According to a second aspect of the present invention, in the first aspect, the sixth aspect is provided.
The gist is to have an elongation of ２５25%.
According to a third aspect of the present invention, in the first or second aspect, the heat seal resin is applied to one surface.

The invention according to claim 4 is the invention according to claims 1 to 3.
In any one of the above items, the smoothing means that the creping process is performed in a wet paper state and the smoothing process is performed simultaneously with the drying.

[0010] The invention of claim 5 is the invention of claims 1 to 4.
In any one of the aspects, the gist is that the surface subjected to the smoothing processing is printed.
According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the width is 8 to 50 mm.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to FIGS. (Raw material used) Examples of the raw material used include pulped vegetable fibers, but are not particularly limited.

The pulped plant fiber can be selected from wood fiber, wood bast fiber, hemp bast fiber, and leaf vein fiber. There are conifers, hardwoods, mitsumata, mulberry, ganja, mulberry, flax, ramie, cannabis, jute, kenaf, manila hemp, sisal hemp, etc.

The pulping method includes a kraft method, a sulfite method, a simple alkali method and the like, and is described in detail in "Craft pulp, non-wood pulp" edited by Japan Society of Paper and Pulp Technology (issued by Japan Association of Paper and Pulp Technology in March 1967). Have been.

Other fibers used as raw materials include
According to the required physical properties, blending of synthetic fibers such as rayon, vinylon, polyester, and polyolefin can also be performed. In addition, polyvinyl alcohol fibers to which a small amount of adhesive synthetic fibers can be added, hardly water-soluble carboxymethylcellulose fibers, chitosan short fibers and the like can be used in an amount of 10% or less, preferably 5% or less. (Preparation method of crepe paper) The wrapping paper of the present invention is prepared by converting a slurry mainly composed of pulped vegetable fibers into a paper having a basis weight of 40 using a paper machine using a net such as a circular net, a short net, an inclined wire, and a long net.
and paper in ^{g / m 2 ~75g / m 2} , the wet paper before drying lead to doctor blade onto a contact roll, and dried against a cylindrical dryer after performing creping, winding and stripping Built in a way to take.

FIG. 1 shows an example in which paper is made by two round paper machines 11. In the same figure, doctor blade 1
Is also used as a metal roll of a press roll, and can effectively perform creping. Thereafter, the creped wet paper web S is pressed against the cylindrical drying cylinder (dryer) 4 by the touch rolls 3 and 12 to be dried effectively. With the touch rolls 3 and 12, smooth processing is performed on both front and back surfaces of the crepe paper. In the present embodiment, smoothing is performed by both touch rolls 3 and 12, but smoothing may be performed only by touch roll 3.

Reference numeral 8 denotes a take-up roll for winding the crepe paper S1 which has been made and smoothed, 9 denotes a blanket, 10 denotes a tension roll, and 13 and 14 denote separation rolls for separating the papermaking S from the blanket 9.

(Creping in the state of wet paper) The wet paper is preferably creped with a water content of 40 to 80%, preferably 50 to 70%. If the water content is 70% or more, the strength of the wet paper becomes weak, and it is difficult to pass the paper from the crepe treatment to the drying step. If the water content of the wet paper is 50% or less, the crepe shape becomes hard and the wet paper becomes hard. Becomes difficult.

[0018] is (coated processing) papermaking as described above, with respect to coiled crepe paper, coated processing of 5g / m ² ~20g / m ² on one surface of the heat sealable resin base paper (crepe paper) Perform heat sealing. As the heat-sealing resin, a resin that matches predetermined heat-sealing conditions and characteristics can be selected. Examples of the resin include vinyl acetate or a copolymer thereof, a polyolefin-based copolymer, an acrylic-based copolymer, and a polyester-based copolymer. In addition, the shape or form in which these resins are supplied,
Pellets, films, aqueous or solvent solutions, aqueous emulsions or dispersions, etc., are processed by coating, hot melt coating, laminating, etc., depending on their shape or form, and are dried if necessary. It is desirable to select a resin having the same elongation as the base paper.

Incidentally, ethylene vinyl acetate (EVA) is included in the polyolefin copolymer or the vinyl acetate copolymer. (Paper band and manufacturing method thereof) A crepe paper which has been coated as described above is cut into a tape shape by a slitter such as a micro-slitter or the like, thereby forming a paper band. The paper width to be cut is set according to the purpose of use. In particular, the range of 15 mm to 50 mm is preferable as a tag band, but if it is 8 mm or more, it can be used for laver and the like.

According to the crepe-attached strip of the present embodiment configured as described above, since the crepe is attached, an appropriate elongation can be obtained in the length direction (papermaking direction). In particular, an elongation of 6 to 25% in the length direction is suitable when this paper band is used as a bill band. If the elongation is less than 6%, the band tends to be cut as in the conventional case. If the elongation exceeds 25%, when used as a bind, the elongation is too large in the length direction and the binding property is deteriorated.

In other words, when a 10,000-yen bill is sealed in units of one million yen, a heat-sealable roll band having a width of 20 mm is used.
It is generally used in banks and the like as a heat-sealable roll large band having a width of 40 mm.

Particularly, in the case of a paper strip having a width of 40 mm, 10
The load on the paper band increases because the volume of the bill bundle of one million increases, but if the elongation is in this range, the band expands in the length direction according to the load, so that the band does not break.

The band is used by binding an object along its length. For example, in the case of a tag band paper, the central portion of the tag bundle is surrounded, the end portions are overlapped with each other, and the overlapped portion is heated to be adhered to each other.

Further, since both front and back sides are smoothed, printing and stamping of financial institution names such as bank names, other symbols, store names, house marks, etc. can be performed in the same manner as in the conventional bill band, and crepe. However, printing, imprinting and the like do not become unclear. The smoothness is provided on both the front and back surfaces. Among them, the smoothness is formed larger on the side facing the surface (dryer surface) of the cylindrical drying cylinder 4.

Further, by smoothing, the heat-sealing resin can be smoothly applied at the time of heat-sealing, and the surface of the resin film formed by the application can be easily smoothed. Furthermore, since the smoothing suppresses an increase in thickness in the thickness direction, although it is provided with crepe, it can be easily formed into a long product when wound up in a roll shape.

Further, according to the present embodiment, the wrinkles given in the length direction at the time of creping become smooth on the entire surface when pressed by the touch roll. become unable to know. That is, in this state,
At first glance, it looks the same as a conventional paper band, and there is no uncomfortable feeling for the user.

FIG. 2 is an enlarged cross-sectional view of the conventional band (tag band) cut in the length direction (papermaking direction), and FIG. 3 is a longitudinal direction (band direction) of the band (tag band) of the present embodiment. It is the expanded sectional view cut | disconnected in FIG. As shown in FIG.
While the fiber (including plant fiber and other fiber) 21 extends straight in the papermaking direction, the band paper 30 of the present embodiment shown in FIG. 3 has the fiber (including plant fiber and other fiber). 31 is largely curved up and down, and both surfaces are made smooth. This is true for the crepe bandage 30.
This shows that the fiber 31 having a potential for stretching is temporarily fixed in a curved state by drying inside the smooth surface. When external tension is applied in the longitudinal direction, the group of fibers 31 temporarily fixed in a curved state expands, thereby exhibiting extensibility.

In addition, since a heat-sealing resin is applied to one side of the band paper 30 in the present embodiment and is temporarily fixed in a curved state by a drying process, a large tensile force acts. Unless otherwise, the state by this temporary fixing can be maintained.

The present invention is not limited to the above embodiment, and the crepe band may be provided with smoothness on only one side. Further, the band is not limited to the use of the tag band, but may be used for other purposes, such as laver, noodle, incense, origami, book, newspaper, mail, and the like.

[0030]

As described in detail above, according to the first to sixth aspects of the present invention, the band is cut off by providing smoothness on the surface despite the creping treatment. Thus, it is possible to provide appropriate elongation and printability.
