Description

  The present invention relates to a label paper for pressure-sensitive adhesive labels, and more particularly to a label paper that can form a laminate layer on the surface of a label during use.

A label paper in which a label paper and a film are laminated is known so that a user can write characters on the surface of the label paper and then stick an adhesive film on the surface of the label paper to form a laminate layer.
For example, the conventional label paper has a structure in which a first release paper, a film, a second release paper, and a label paper are laminated in this order, and a pair of identical laminated structures, symmetrical to the folding line provided on the first release paper. Label paper with the same shape is placed. In use, after writing characters on one label paper, remove the other second release paper and label paper, fold it from the fold line, stick the film on the label paper, release the fold, and laminate To obtain a labeled label. (For example, refer to Patent Document 1).

  There is also a label paper in which a film, release paper, and label paper are laminated in this order. In this method, after writing characters or the like on a label sheet in use, a label is first attached to an object. Subsequently, the film remaining on the label paper is removed and a laminated layer is formed on the label. (For example, refer to Patent Document 2).

Due to the recent development of computer-related technology, there is a demand for users to print characters and images on the label surface using a printer.
The above-described conventional four-layer laminated label paper has a large thickness and is difficult to pass through with a normal printer. Also, half of the label paper is discarded, which is uneconomical.

Next, in the second conventional example, it is necessary to further stick a film after sticking the label paper to the object. Labels can be attached to curved surfaces such as the back cover of books, vertical surfaces such as cabinet doors, and slopes. After sticking a label on such a surface, it is difficult to attach an adhesive film from above, and a laminate failure may occur, such as wrinkling of the film.
Furthermore, it is difficult to accurately position the adhesive film according to the label surface in such a place, and the positional deviation between the label paper and the film also occurs.

Accordingly, an object of the present invention is to obtain a label sheet with a laminate film suitable for printing using a normal printer. Moreover, this invention makes it a subject to obtain the label paper which can perform a lamination operation | work at appropriate work places, such as a desk. Furthermore, an object of the present invention is to obtain a label sheet that can be easily positioned during a laminating operation.
Other problems and advantages of the present invention will become apparent from the description of the present invention described below.

In the label paper of the present invention, an adhesive layer A is formed on a film, a release paper is pasted on the adhesive layer A, an adhesive layer B is formed on the release paper, and the adhesive paper The release paper has a release treatment layer a on the surface in contact with the pressure-sensitive adhesive layer A, and the release paper is in contact with the pressure-sensitive adhesive layer B. A label paper having a release treatment layer b on its surface, where Fa is the peel force between the film and the release paper, and Fb is the peel force between the label paper and the release paper, the formula (1 ) Label paper satisfying
Fa <Fb (1)
For the label paper of the present invention, after filling in the necessary information on the label paper, the laminate of the label paper and the release paper (hereinafter referred to as “pre-coated label”) is peeled off from the label paper, and turned over and turned into the label paper. The label film is laminated by pressure-bonding to the remaining film.

  A laminate structure (hereinafter sometimes referred to as a differential release structure) in which the peel force (Fa) between the film and the release paper was weaker than the peel force (Fb) between the label paper and the release paper was employed. That is, the peel force (Fa) between the film and the release paper is relatively lightened, and the peel force (Fb) between the label paper and the release paper is relatively heavy. For this reason, it is possible to easily peel off the uncoated label from the label paper as a single unit.

The label paper of the present invention has a three-layer structure of film, release paper, and label paper. The total thickness of the label paper can be reduced, and printing can be performed with a normal printer. In particular, the label paper of the present invention is suitable for printing with a printer because there is no step on the entire surface of the label paper.
In addition, laminating work by peeling off the label paper before coating, turning it over, and pressing on the fill surface can be performed at an appropriate work place.

  Furthermore, since both sides of the label before coating are not exposed, it is possible to hold or change any part of the label paper before coating during the laminating operation, which facilitates operations such as positioning. Yes. In addition, except for the second label described in detail below, the label piece and the laminate film have the same shape, the film does not protrude from the label, the aesthetic appearance around the pasted label is maintained, and the laminated label with a small amount of waste Paper can be obtained. Furthermore, the laminate can improve the water resistance of the label and the printing applied to the label.

In one embodiment of the label paper of the present invention, the total thickness of the label paper may be 300 μm or less.
General inkjet printers and laser printers used in offices and homes can pass printing media having a thickness of about 300 μm. According to the present embodiment, a label sheet that can be printed using such a printer can be obtained. The label paper of the present invention can be made thicker. Especially for handwritten label paper, it is not necessary to consider the thickness.

In one embodiment of the label paper of the present invention, the surface state of the release treatment layer a may be different from the surface state of the release treatment layer b.
In the present embodiment, the difference peel structure of the label paper is realized mainly by changing the peel processing on the front and back surfaces of the release paper. If it does in this way, it will become possible to design the adhesive force of an adhesive layer, especially adhesive layer B comparatively freely. For example, if the pressure-sensitive adhesive layer B has a relatively weak adhesive strength, it becomes a laminate label that can be easily peeled off after adhesion, and uses of the label are expanded.
For adjusting the adhesive strength of the pressure-sensitive adhesive layer B, various means for realizing a differential peel structure described later by the difference in the pressure-sensitive adhesive layer can be applied.

In one embodiment of the label paper of the present invention, the label paper and the release paper are punched with the same contour line, and the line portion of the film facing the contour line is cut leaving a part of the uncut portion. The first label area may be provided which is divided into a fixed shape by a contour line.
In the present embodiment, the number of first label regions provided on one label sheet may be single or plural. There is a lower limit to the size of a print medium that can be passed by a general printer, and it is usually about a public postcard. According to the present embodiment, even a label smaller than the lower limit of printer paper feeding can be printed by the printer. In other words, a label piece with a small finished print can be printed and printed using a normal printer.

The outline of the punching process may be an independent single line surrounding the label area, or a part thereof may be common with the outline of the label sheet. For example, when two label regions are provided on a label sheet, the punching line may be a single straight line.
When a plurality of first label areas are provided, the film area after the uncoated label is peeled is adjacent to at least one side of the label paper on which the label paper remains. When the pre-coated label is turned upside down and pressure-bonded to the film, the other first label area that remains is a guide for positioning.

In one embodiment of the label sheet of the present invention, a plurality of first label areas may be formed on the label sheet, and the plurality of first label areas may be provided at intervals.
If there is an interval between the plurality of first label regions, the film surface after the pre-coated label is peeled is divided by the label paper left on the interval. When the pre-coated label is turned over and pressure-bonded to the film, the existing label paper serves as a guide for positioning and makes positioning easier.

In one embodiment of the label paper of the present invention, the first label area may be a square-like shape.
A square-like shape is a square, a rectangle, a square with rounded corners, a rectangle with rounded corners, a shape in which some of these sides are expanded outward, a shape in which some of these sides are indented, and its sides Some or all of them are squares or rectangles with wavy lines.
Since the label generally has a square-like shape, according to the present embodiment, the label sheet is more convenient to use.

In one embodiment of the label sheet of the present invention, the first label area is an index sheet, and a part of the label sheet is on a straight line connecting the midpoints of two long sides facing each other of the rectangular similar shape. It may be cut.
In the present embodiment, the middle line of the first label region is at least partially cut, and the work of folding the label in half is facilitated when attaching the index label. Since the index sheet is folded in two and pasted, the work of pasting the laminate film after pasting the label in the conventional example is very difficult. Therefore, this is a preferred example of use of the present label paper to be pasted after laminating at an appropriate work place (for example, on a desk).

In one embodiment of the label paper of the present invention, a mark indicating the long side of the square-like shape may be attached to the surface of the label paper between the first label regions.
When peeling off the pre-coated label from the label paper of the present invention, it is preferable to peel off the linear portion of the first label area. In the case where the first label region has a square-like shape, the preferred peeling position is a part on the long side. Therefore, a label sheet that is more convenient to use can be obtained by attaching a mark indicating the long side and clearly indicating the peeling position. Here, when the first label region is square or substantially square, the long side referred to in the present embodiment means any one of the four sides.

In one embodiment of the label paper of the present invention, the label paper and the release paper are punched with the same contour line, and the film is punched into a shape surrounding the contour line outside the contour line. A second label region may be provided which is provided with a line and is divided into a fixed shape by the contour line.
The second label according to the present invention is laminated with a film that is slightly larger than the label, and is attached to an object with an adhesive applied to the back surface of the label itself and an adhesive film attached to the film protruding from the label. It is done. For this reason, the label is more strongly protected from the ingress of water and gas. Moreover, the adhesion of the label becomes stronger.

Furthermore, when removing the release paper remaining on the second label piece separated after lamination, it is easy to apply a force in the bending direction to the label piece using the protruding film part as a finger. Paper removal work becomes easy.
As described in the embodiment of the label sheet provided with the first label area, in this embodiment, the number of second label areas provided on one label sheet may be single or plural. Also good.

Further, the film punching line may be an independent single line surrounding the second label region, or a part thereof may be common with the outline of the label sheet.
In the present embodiment, the film area after the uncoated label is peeled is surrounded by the label paper remaining on the label paper. When the pre-coated label is turned over and pressure-bonded to the film, the remaining label paper is used as a guide for positioning.

In one embodiment, the label paper of the present invention is a label paper provided with a plurality of second label areas, and the second label area has a square-like shape and surrounds the plurality of second label areas. The blanking lines may be provided at intervals.
A square-like shape is a square, a rectangle, a square with rounded corners, a rectangle with rounded corners, a shape in which some of these sides are expanded outward, a shape in which some of these sides are indented, and its sides Some or all of them are squares or rectangles with wavy lines.
Since the label generally has a square-like shape, according to the present embodiment, the label sheet is more convenient to use.
In addition, after removing the label area, a part of the film remains on the label paper, and the effect of facilitating the removal of the adjacent label area can be obtained.

  The embodiments of the present invention described above can be implemented in combination as much as possible.

According to the present invention, it is possible to obtain a label sheet with a laminate film suitable for printing using a normal printer in an office or home. Further, according to the present invention, a label sheet that can be easily laminated can be obtained.
In a preferred embodiment of the present invention, it is possible to obtain a label sheet in which the label and the film can be easily positioned during the laminating operation.

In the present invention, the peeling force (Fa) between the film and the release paper is adjusted by changing the surface shape of the release treatment layer a and the adhesive strength of the pressure-sensitive adhesive layer A (in some cases, the surface shape of the film at the same time). Can do. Preferably, Fa is adjusted by changing the surface shape of the release treatment layer a.
The peeling force (Fb) between the label paper and the release paper can be adjusted by changing the surface shape of the release treatment layer b and the adhesive force of the pressure-sensitive adhesive layer B (in some cases, the surface shape of the label paper at the same time). . Preferably, Fb is adjusted by changing the surface shape of the release treatment layer b.

  The pressure-sensitive adhesive layer A and the pressure-sensitive adhesive layer B used in the present invention are pressure-sensitive adhesives. As such an adhesive, a known adhesive (for example, acrylic, rubber, urethane, etc.) can be used. An acrylic pressure-sensitive adhesive is preferred.

The peel force Fa between the film and the release paper and the peel force Fb between the label paper and the release paper satisfy Expression (1).
Fa <Fb (1)
Preferably, Fb is 1.5 times or more of Fa, more preferably 1.5 times or more and 10 times or less, further preferably 1.5 times or more and 5 times or less, and most preferably 2 times or more. 4 times or less. When the relationship between Fa and Fb is within this range, the label before peeling can be easily peeled off, and the degree of freedom in designing the adhesive strength of the adhesive layer A and / or the adhesive layer B is improved.
Here, peeling force (Fa, Fb) is the median value of the measured values measured by the T-type peeling method according to JIS-Z-0237 (the same applies hereinafter).
To give a specific example, Fa is in the range of 70-300 mN / 100 mm, Fb is in the range of 140-800 mN / 100 mm, and satisfies the above formula (1). The numerical range described above is an example and does not limit the technical scope of the present invention.

It implement | achieves by changing the surface state of a peeling process layer by means, such as.
Furthermore, the difference peel structure can also be realized by using the difference in the adhesive strength of the pressure-sensitive adhesive layer and the difference in the surface state of the release treatment surface in combination.

The punching process in the case where the first label area is provided refers to a process in which a laminated body having a laminated structure can be cut and an area surrounded by a cutting line can be peeled off. The blanking line is provided for the purpose of peeling off the pre-coated label from the label sheet in units of label areas.
The label paper and the release paper are cut by the punching process, and these are supported by the film and the adhesive layer A, and the label paper and the release paper hold the shape of the label paper. Here, a cutting line is also provided in the film, but a part of the cutting line has a non-cutting part. Therefore, the film maintains the shape of the label paper, and the release paper and the label paper supported by the film also maintain the shape of the label paper.

  One or more anchor portions may be provided on the cutting line for punching. The anchor portion is a portion where a very short line is connected without being cut on the cutting line, and has a role of assisting in maintaining the shape of the label sheet. An example of the distance between the anchor portions is 0.2 mm. In order to print / print on label paper with a printer, it is preferable to provide an anchor portion on the punch line.

When the first label region is provided, a cutting line that leaves a part of the non-cutting portion is further provided in the line portion of the film that faces the punching line. The film cut line is provided to separate the film from the label paper after the laminating process.
“A cutting line that leaves some uncut portions” means a cutting line (for example, a micro-sewing machine line) in which a short interval cut and an uncut are alternately repeated, a relatively long cut and a relatively short uncut. Alternately continuous cutting lines (for example, one-dot chain line or two-dot chain line), relatively long cuts and relatively short uncuts alternately and irregularly continuous cutting lines (having anchor portions) Cutting line). Among these, a cutting line in which a relatively long cut and a relatively short uncut are alternately arranged regularly or irregularly is preferable. Moreover, it is preferable that the length of a short chain line or the length of the anchor portion is 0.2 to 0.4 mm.

Further, when the outline of the punching process is an independent single line surrounding the label area and the label area has a square-like shape, one or more uncut portions are present on each of the pair of sides facing the outline. It is preferable to be provided.
Therefore, the film is kept integral until an appropriate external force is applied to the non-cut portion to separate it.

In the present invention, the shape of the label region can be a square, a circle, an ellipse, a polygon, a doll, a building exterior, or the like. Further, a plurality of label regions having the same shape can be provided on one label sheet, and label regions having different shapes can be mixed.
The intervals provided between the label areas may be provided all around the label area, or may be provided only in the vertical direction or only in the horizontal direction. More preferably, the spacing is provided all around the label area.

In the present invention, index paper refers to a piece of heading paper to be attached to a side portion of paper such as a notebook, ledger, or file.
In the index sheet of the present invention, it is sufficient that at least a part of the partial cutting line provided on the line connecting the middle points of the long sides is cut, or the whole cutting line may be cut. Only the label paper is cut at this cutting line, and the release paper portion corresponding to the line is not cut. The cut label paper is supported by the release paper and the pressure-sensitive adhesive layer B, and the shapes of the label paper and the uncoated label are maintained. Moreover, in the label piece after the lamination process, the cut label paper is supported by the film and the adhesive layer A, and the shape of the label piece is maintained.

  The place to mark the long side of the square-like shape is the interval portion of the label area, and is the surface of the label paper (the back surface of the surface in contact with the adhesive layer B). In addition, as the mark, an appropriate means such as an arrow, a square mark, a circle mark, or coloring along the side can be adopted.

  Regarding the second label region, the distance between the second label region and the film punching line surrounding the second label region is usually 1 mm to 5 mm, preferably 2 mm to 4 mm, more preferably 2.5 mm to 3.5 mm. If it is this space | interval range, the operation | work which separates the laminated label area | region will become easy. Further, the interval between the second label contour line and the film punching line may be the same interval around the entire circumference, or may be different intervals. According to the arrangement of the second label area provided on one sheet of label paper, this interval can be changed on the left and right and top and bottom of the second label area. Moreover, it is also arbitrary to change a space | interval on one side especially for reasons, such as a design, using a film with a pattern.

Furthermore, the space | interval provided between film punching process lines is 2 mm-5 mm normally, Preferably it is 2.5 mm-3.5 mm. With this spacing, the laminated label area can be easily separated.
The film-cutting line may be a continuous cutting line or a cutting line that leaves some uncut portions. A cutting line that leaves some uncut parts is a cutting line in which short-interval cuts and uncuts are alternately repeated (for example, a micro-sewing machine line), relatively long cuts and relatively short uncuts alternately Regularly continuous cutting lines (for example, one-dot chain line shape, two-dot chain line-shaped cutting line), relatively long cuts and relatively short uncuts alternately alternate cutting lines (cutting lines having anchor portions) ) Etc.
The punching process provided on the label paper and the release paper is the same as the punching process described for the first label region. An anchor portion may be provided on this punching line as in the punching process described for the first label region.

As the label paper used in the present invention, coated paper, fine paper, craft paper, finely coated paper, thermal paper, and other papers can be used. A synthetic resin film subjected to ink receiving processing can also be used.
When printing with an ink jet printer, it is preferable to use paper dedicated to the ink jet printer. Since a normal ink jet printer uses water-soluble ink, it is desirable to laminate the printing surface in order to protect the printing surface, which is a preferred field of application of the present invention.
As the label paper, white paper or colored paper can be used. In addition, vertical, horizontal and grid-like ruled lines may be printed in advance. Further, preliminary printing such as underline, company name, library name, and trademark may be made.

  The film is a transparent protective film. Therefore, transparent, translucent, colored films, patterned films, etc. can be used. The material is usually an olefin resin or an ester resin. Examples of the olefin resin include polyethylene, polypropylene, polystyrene, and polyvinyl chloride. Examples of the ester-based resin include polyethylene terephthalate (PET) and polybutylene terephthalate. PET is preferable from the viewpoint of dimensional stability and transparency.

  The label paper according to the present invention will be further described below with reference to examples. The dimensions, materials, shapes, relative positions, etc. of the members and parts described in the embodiments of the present invention are not intended to limit the scope of the present invention to those unless otherwise specified. It is merely an illustrative example.

  FIG. 1 is a schematic sectional view of a label sheet according to the first embodiment. The label paper 1 is a film 11, an adhesive layer A (12) formed on one side of the film 11, a release paper 13 adhered thereon, an adhesive layer B (17) formed thereon, It consists of label paper 18 affixed to. The pressure-sensitive adhesive layer A (12) is formed over the entire area of one side of the film 12. The pressure-sensitive adhesive layer B (17) is formed on the entire area of one side of the label paper 18. The film 11 is a PET transparent film. The release paper 13 has a release treatment layer a (15) on the surface facing the film 11. The release paper 13 has a release treatment layer b (16) on the surface facing the label paper. The release treatment layer is formed by applying a silicon resin solution to the release base paper 14.

The amount of silicon resin applied to the release treatment layer a (15) is larger than the amount of silicon resin applied to the release treatment layer b (16). The pressure-sensitive adhesive layer A (12) is a solvent-type acrylic pressure-sensitive adhesive. The pressure-sensitive adhesive layer B (17) is an emulsion type acrylic pressure-sensitive adhesive.
Since it was set as the above structure, peeling force (Fa, Fb) is mainly determined by the peeling process layer (15, 16). Since the release treatment layer a (15) has a larger amount of silicone resin applied than the release treatment layer b (16), the release force between the release paper 13 and the adhesive 12 is the same as the release force between the release paper 13 and the label paper 18. Compared to lighten. That is, the difference peel structure of the label paper 1 is mainly realized by the difference in the surface shapes of the release treatment layer a and the release treatment layer b.

In this embodiment, Fa is 170 mN / 100 mm, and Fb is 500 mN / 100 mm.
The label paper 18 is paper for inkjet printer use.
The thicknesses of the film 11, the release paper 13, and the label paper 18 are 25, 100, and 100 μm, respectively, and the total thickness of the entire label paper is 270 μm.

In the figure, reference numeral 31 denotes a first label area, which is surrounded by a contour line 19. The contour line 19 is a blanking line, the label paper 18 is cut along a line 20, and the release paper 13 is cut along a line 21. The film 11 is cut at a line 22 corresponding to the contour line 19 leaving an anchor portion. (The line 22 is shown in a broken line shape for the purpose of explanation. Actually, cut and uncut sections appear.) The length of the anchor portion is 0.2 mm.
The film is continuous by the anchor portion and can retain the shape of the entire film. Although the label paper 18 and the release paper 13 are cut, since they are supported by the film 11 via the adhesive layers A and B, the entire shape is maintained.

FIG. 2 is an explanatory diagram of the surface of the label paper 1. The label sheet 1 of the present embodiment has twelve first label areas 31 surrounded by a contour line 19. The first label regions 31 are arranged at intervals (30a, 30b, 30c). The first label area 31 is an index label. Its shape is a square-like shape (a rectangle with rounded squares that is recessed at the midpoint of the long side). The length of the long side of the outer shape of the first label region 31 is indicated by an arrow 33.
Reference numeral 35 denotes a cutting line provided in the label area. The cutting line 35 is provided on a straight line connecting the midpoints 36a and 36b of the opposing long sides 32a and 32b of the first label region. As for the cutting line 35, only the label paper is cut, and the line portion of the release paper 13 facing the cutting line 35 is connected.

Next, how to use the label sheet 1 will be described with reference to FIGS. 1, 2 and 3 as necessary.
First, characters 41 are entered in the first label area 31 of the label paper 18 by means of a printer, handwriting or the like.
Next, the pre-covering label (label paper 18, pressure-sensitive adhesive layer B (17) and release paper 13 laminate) in the first label region 31 is peeled off. The first label region 31 has been punched, and the label paper and the release paper are cut along the contour line, so that the peeling can be easily performed. Further, since the label paper has a different peel structure, the peeling treatment layer a (15) and the pressure sensitive adhesive layer A (12) are peeled when a peeling force is applied.

As a result of this peeling, a laminate of the pressure-sensitive adhesive layer A and the film 11 remains in the label area of the label paper 1. The stacked body 42 is surrounded by intervals 30a, 30c and the like. The pre-coated label that has been peeled off first is turned over, and the label paper printing surface is pressure-bonded to the remaining laminate 42. At this time, the labels before peeling are positioned using the intervals 30a and 30c as a guide. Reference numeral 43 denotes an inverted pre-coated label.
The film 11 is laminated on the label paper printing surface through the pressure-sensitive adhesive layer A by this reversal and pressure bonding. Next, the film 11 is separated from the label paper 1 according to the cutting line provided on the film surface. In the figure, reference numeral 44 denotes a label region from which the film has been separated, and is hollow.

  Thus, the laminated index label is completed. The release paper 13 remaining on the label piece is removed, the pressure-sensitive adhesive layer B is exposed, and the index label is attached in a folded state with a part of the paper surface at the attaching position. At the time of folding in half, the cutting line 35 serves as a guide for the folding line.

FIG. 4 is a front view of the label sheet 1 according to the second embodiment. The laminated structure of the label paper 1 is the same as that of the label paper described in the first embodiment.
The label sheet 1 of the present embodiment has nine first label regions 311 surrounded by a contour line 191. The first label regions 311 are arranged at intervals (30d, 30e). The first label area 311 is a label. Its shape is rectangular.
The outline 191 is subjected to the same punching process as in the first embodiment.

In the figure, reference numeral 34 denotes a mark indicating the long side 321 of the first label region 311. The mark 34 indicating the long side is provided in the interval portion (30d) of the label area. A mark 34 indicating the long side is printed on the label paper.
The method of using the label paper 1 of this embodiment is the same as the method described in the first embodiment. However, when the pre-coated label is peeled off from the label sheet 1, the peeling can be performed more easily by using the mark 34 indicating the long side as a guide.

FIG. 5 is a schematic sectional view of a label sheet according to the third embodiment. The laminated structure of the label paper 1 is the same as that of the label paper described in the first embodiment, and the same members are assigned the same drawing numbers.
In the figure, reference numeral 51 denotes a second label area, which is surrounded by a contour line 52. The contour line 52 is a blanking line, the label paper 18 is cut along a line 53, and the release paper 13 is cut along a line 54.

The film 11 is punched with a film punching line 56 that overlaps the film contour 55 surrounding the outside of the contour 52. In this example, the film punching line 56 is a continuous cutting line.
These punching processes are performed, for example, by creating a laminated label paper 1 and then cutting the label paper 18 and release paper 13 from the label paper 18 surface of the label paper 1 to cut the label paper 18 and the release paper 13 from the surface of the film 11 This can be done by inserting a sword and cutting the film 11.

FIG. 6 is an explanatory diagram of the surface of the label sheet 1. The label sheet 1 of the present embodiment has nine second label areas 51 surrounded by a contour line 52. The second label area 51 is slightly larger than the outline 52 and is surrounded by a film outline 55 surrounding the outline 52. (The film contour 55 appears on the back surface of the label paper 1 and does not appear on the front surface, but is illustrated in the front surface explanatory diagram for the purpose of explanation. Also, since it is a continuous cutting line, it appears on the back surface with a solid line. The film contour 55 (shown with a broken line for purposes) overlaps the film punch line 56.
The distance between the contour line 52 and the film contour line 55 is 3 mm between the short side 52a of the contour line and the short side 55a of the film contour line (indicated by the arrow 61), and between the long side 52b of the contour line and the film contour line The distance between the long sides 55b (indicated by the arrow 66) is 3 mm. The interval between adjacent film contours is 3 mm on both the short side (indicated by arrow 62) and the long side (indicated by arrow 67). Further, the distance between the outline of the label sheet 1 and the film outline (indicated by arrows 63 and 68) is 3 mm.

Next, how to use the label paper according to the third embodiment will be described.
First, characters are entered in the second label area 51 of the label paper 18 by means of a printer, handwriting or the like.
Next, the pre-covering label (label paper 18, pressure-sensitive adhesive layer B (17) and release paper 13 laminate) in the second label region 51 is peeled off. The label region 51 has been punched, and the label paper and the release paper are cut along the contour line, so that the peeling can be easily performed. Further, since the label paper has a different peel structure, the peeling treatment layer a (15) and the pressure sensitive adhesive layer A (12) are peeled when a peeling force is applied.

As a result of this peeling, a laminate of the pressure-sensitive adhesive layer A and the film 11 remains in the label area of the label paper 1. The pre-coated label that has been peeled off first is turned over, and the label paper printing surface is pressure-bonded to the remaining laminate.
The film 11 is laminated on the label paper printing surface through the pressure-sensitive adhesive layer A by this reversal and pressure bonding. Next, when the second label area is pushed in the reverse direction of the label paper, the film 11 is separated from the label paper 1 according to a film punching line 56 (a line overlapping the film outline 55).
Thus, the laminated index label is completed, and the release paper 13 remaining on the second label piece is removed.

FIG. 7 is an explanatory diagram showing an operation of removing the release paper 13 from the second label piece. As shown by the arrow 71, a part of the second label piece is sandwiched between fingers, and at the same time, the contour line portion of the film 11 is pushed and bent in the direction of the arrow 72. By this force, a part between the release paper 13 and the label paper 18 (indicated by an arrow 73) is peeled off. The label is changed, and the release paper 13 is removed from the partially peeled portion 73.
Thereafter, the label piece is attached to the object by the pressure-sensitive adhesive layer B exposed from the label piece and the pressure-sensitive adhesive layer A exposed from the film surface.

  The label paper according to the present invention can be used as an adhesive label paper, for example.
