Description

The present invention relates to a laminated sheet, a continuous sheet, and a baggage tag for wrapping around an object having a longitudinal direction.

Conventionally, when shipping baggage (carry-on bags, backpacks, Boston bags, etc.), the baggage is often delivered by covering it with a transparent plastic cover and placing a delivery slip showing the delivery destination in a pocket in the transparent cover, wrapping a large tag around the baggage and attaching the delivery slip to the tag, or wrapping a bag-shaped tag around the baggage and placing the delivery slip inside the tag (bag). The delivery slip used in this case is in the form of a laminated sheet made of multiple base materials and uses an adhesive layer and a release layer (see Patent Document 1).

JP 2013-94974 A

However, with the above-mentioned conventional delivery slips, when the release paper is peeled off, a relatively strong adhesive layer is exposed, which raises the risk that the wrapped delivery slip will stick to the handle of the baggage and soil the baggage. One possible solution to this problem is to expose some of the adhesive so that it can be attached, but this creates a gap between the handle of the wrapped baggage and the delivery slip, which has a ring-shaped cross section, making it difficult to secure the delivery slip in place. There is also a demand to conserve the adhesive that is exposed in order to wrap it around the baggage.

The present invention aims to provide a laminated sheet, continuous sheet, and baggage tag that can conserve exposed adhesive and can be easily fixed to the object to which it is attached.

In order to solve the above problems, the present invention provides
A laminated sheet comprising a surface substrate having a release piece and a support substrate bonded to each other via an adhesive layer, a release layer being provided between the release piece and the support substrate, and the release piece being peelable from the support substrate,
The present invention provides a laminated sheet in which an adhesive layer containing a pressure-sensitive adhesive is formed on the surface of the supporting substrate opposite to the surface substrate, and the adhesive layer is formed such that adhesive-coated sections to which the pressure-sensitive adhesive is applied and adhesive-uncoated sections to which the pressure-sensitive adhesive is not applied are alternately formed so as to extend in a diagonal direction relative to one side of the laminated sheet.

The laminate sheet according to the present invention is
The width of the adhesive-coated portion may be narrower than the width of the adhesive-free portion.

The laminate sheet according to the present invention is
The angle that the adhesive-coated portion makes with one side of the laminated sheet may be equal to or greater than 30 degrees and equal to or less than 60 degrees.

The laminate sheet according to the present invention is
A delivery information field may be formed on the surface of the release piece and on the surface of the surface base material other than the release piece, so as to function as a delivery slip.

The laminate sheet according to the present invention is
A delivery information section is formed on the surface of the release piece and on the surface of the surface base material other than the release piece, and an adhesive layer superimposed on the portion of the surface base material other than the delivery information section formed on the portion other than the release piece may function as an attachment section for wrapping around an attachment target.

In addition, in the present invention,
A continuous sheet formed by connecting a plurality of the laminated sheets via a separation line,
The directions in which the adhesive-applied portions of the adjacent laminated sheets extend are symmetrical with respect to the intended separation line;
A continuous sheet is provided in which the centers of the ends of the adhesive-coated portions along the intended separation line are offset from each other.

In addition, in the present invention,
A baggage tag comprising: a surface substrate having a release piece and a support substrate bonded to each other via an adhesive layer; a release layer provided between the release piece and the support substrate; and the release piece being removable from the support substrate,
A self-adhesive layer containing a pressure-sensitive adhesive is formed on the surface of the support substrate opposite the surface substrate, and the self-adhesive layer has adhesive-coated sections to which the pressure-sensitive adhesive is applied and adhesive-uncoated sections to which the pressure-sensitive adhesive is not applied alternately so as to extend in a diagonal direction relative to one side of the laminated sheet.

The present invention makes it possible to conserve exposed adhesive and to easily attach the product to the object of attachment while reducing the risk of soiling the object of attachment.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
<1. Configuration of Laminated Sheet>
FIG. 1 is a diagram showing a laminated sheet according to an embodiment of the present invention. FIG. 1 shows a laminated sheet in the form of a baggage tag as an example. In FIG. 1, FIG. 1(a) is a front side plan view, FIG. 1(b) is a cross-sectional view corresponding to A-A in FIG. 1(a), and FIG. 1(c) is a back side plan view. In the laminated sheet 1, in reality, either side may be the front side (front side) or the back side, but for convenience, the side shown in FIG. 1(a) will be the front side and the side shown in FIG. 1(c) will be the back side, and the following description will be given. In addition, in the layer structure of FIG. 1(b), either side may be the upper layer and either side may be the lower layer, but for convenience, the upper side (the side of the surface substrate 2) of FIG. 1(b) will be the upper layer, and the lower side (the side of the self-adhesive layer 7) of FIG. 1(b) will be the lower layer, and the following description will be given. The ratio of the thickness of each layer expressed in FIG. 1 and the ratio of the thickness of each layer to the area of the plan view are not necessarily the same as the actual ones for convenience of illustration.

As shown in FIG. 1, the laminated sheet according to this embodiment also functions as a baggage tag. A baggage tag is attached to baggage in order to manage the baggage at an airport or the like, and has substantially the same function as a delivery slip for delivering the baggage. For this reason, a delivery slip 2a having a delivery information section (not shown) printed on its surface, a sticker 2b having a delivery information section (not shown) printed on its surface, and a surface base material 2 having an attachment section 2c for attaching to the baggage arranged in the left-right direction (horizontal direction) in the figure are provided on the top layer. That is, a delivery information section is formed on the surface of the delivery slip 2a, which is the peelable piece, and on the surface of the sticker 2b, which is the part of the surface base material 2 other than the peelable piece.

The self-adhesive layer 7, which is overlaid on the attachment section 2c, which is the portion other than the delivery information section formed on the attachment slip 2b, which is the portion of the surface base material 2 other than the peel-off piece, functions together with the attachment section 2c to wrap the attachment target. The delivery information section is formed on a typical delivery slip, and although not shown in the figure, it has a writing/printing frame within which the addresses and names of both the recipient and sender can be written and/or printed.

As shown in FIG. 1(a), the surface base material 2 is formed so that it can be separated into a delivery slip 2a and an attachment slip 2b by a separation planned line 9a formed in the vertical direction (vertical direction) of the drawing. The separation planned line 9a may be a perforation or any other form that allows separation of the delivery slip 2a, which is a peelable piece, but in this embodiment, it is a cut that penetrates the surface base material 2 and does not reach the support base material 6. In other words, in this embodiment, when viewed as a whole laminated sheet 1, the separation planned line 9a is a cut with a half-cut structure.

As shown in FIG. 1(a), the surface base material 2 is provided with an attachment portion 2c, which is separated from the sticker sheet 2b by a division line 9b formed in the vertical direction of the drawing. In this embodiment, the division line 9b is formed as a perforation.

As shown in the A-A cross-sectional view of FIG. 1(b), the lower layer of the delivery slip 2a (surface substrate 2) is superimposed on the support substrate 6, which has a sealing layer 5 on the surface and a self-adhesive layer 7 on the back, via a peeling layer 3 and an adhesive layer 4. That is, the delivery slip 2a, the peeling layer 3, the adhesive layer 4, the sealing layer 5, the support substrate 6, and the self-adhesive layer 7 are laminated in this order. The self-adhesive layer 7 is exposed as the lowest layer. In addition, the two layers, the peeling layer 3 and the adhesive layer 4, realize a pseudo-adhesive structure that can be pseudo-adhesive. The presence of the peeling layer 3 makes it possible to peel the delivery slip 2a, which is a peeled piece, from the support substrate 6. And in the lower layer of the sticker slip 2b (surface substrate 2), the configuration of the sealing layer 5, the support substrate 6, and the self-adhesive layer 7 is the same as the lower layer of the delivery slip 2a, but it is different in that it does not have a peeling layer and only the adhesive layer 8 is provided. The adhesive layer 8, which has strong adhesion, makes it difficult for the sticker slip 2b to peel off from the support substrate 6.

In this embodiment, the same adhesive is used for adhesive layer 4 and adhesive layer 8, but different adhesives may be used. The laminated sheet 1 is used by bending the mounting portion 2c and wrapping it around a part of the attachment target such as a delivery item, and bonding the self-adhesive layers 7 together.

In the A-A cross-sectional view of FIG. 1(b), the thickness of each layer is shown to be approximately the same for the sake of simplicity, but in reality, the thickness of each layer is different, as described below. In addition, in the A-A cross-sectional view of FIG. 1(b), the ratio of the length in the left-right direction of the drawing to the thickness in the up-down direction of the drawing is different from the actual ratio. In reality, the length in the left-right direction of the drawing is several centimeters to several tens of centimeters, while the thickness in the up-down direction of the drawing is approximately several hundred μm. Of course, these lengths and thicknesses are not limited to these. In addition, in the lower layer of the delivery slip 2a (surface substrate 2), the release layer 3, adhesive layer 4, and support substrate 6 are provided across the entire surface of the delivery slip 2a.

2. Composition of each layer
As the surface substrate 2, any material having sufficient strength and printability and transportability by a printer can be used. For example, high-quality paper, craft paper, copy paper, glassine paper, parchment paper, rayon paper, coated paper, synthetic paper, paper laminated with a resin film, and other papers are preferably used, but resin films such as cellophane, oriented polypropylene, polyethylene terephthalate, oriented polystyrene, and polyvinyl chloride may also be used. The thickness of the surface substrate 2 is preferably about 20 to 200 μm. Furthermore, in order to provide copying characteristics when a copy sheet or the like is superimposed on the laminated sheet 1, a heat-sensitive coloring layer made of a leuco dye or the like may be provided. The supporting substrate 6 may also be the same as the surface substrate 2.

The above-mentioned release layer 3, adhesive layer 4, sealing layer 5, and self-adhesive layer 7 are not particularly limited in composition as long as they are suitable for the laminated sheet according to this embodiment, but preferred examples are listed below.

As the peeling layer 3, it is preferable to use a resin with low adhesiveness so that the delivery slip 2a can be easily peeled off from the support substrate 6. It is most preferable to use an olefin-based (co)polymer such as polyethylene, polypropylene, or polybutylene, but other films made of thermoplastic resins such as polystyrene, polyvinyl butyral, vinyl acetate polymer, ethylene-vinyl acetate copolymer, vinyl chloride-vinyl acetate copolymer, acrylic resin, cellulose resin, and mixtures thereof may also be used. Films made of thermosetting resins such as polyurethane may also be used. Furthermore, antioxidants, heat stabilizers, ultraviolet absorbers, slip agents, antistatic agents, antifogging agents, colorants, fillers, and the like may be added as desired. The amount and thickness of the resin to be applied to form the peeling layer 3 are not particularly limited, but preferably the amount is 0.1 to 10 g/m ² and the thickness is 0.1 to 10 μm.

The adhesive layer 4 can be, for example, a thermoplastic resin such as a urethane or acrylic resin, and is applied to a thickness of about 0.1 to 50 μm by a known printing method such as a flexographic method or a gravure method, or a coating method, and is dried as necessary after bonding. The surface substrate 2 and the support substrate 6 are bonded together by a wet or semi-wet lamination method in which the adhesive (or resin) is bonded while it is still wet, a thermocompression bonding method, or a pressure-sensitive method.

The filling layer 5 is a layer for filling the supporting substrate 6 so that the adhesive of the adhesive layers 4 and 8 does not penetrate into the supporting substrate 6, and may be made of polyethylene, polyvinyl alcohol, clay, or the like. The application amount and application thickness of the filling agent for forming the filling layer 5 are not particularly limited, but preferably, the application amount is 0.1 to 20 g/ ^m2 and the application thickness is 0.1 to 20 μm.

The self-adhesive layer 7 is a layer capable of bonding self-adhesive layers together with a relatively weak pressure, and contains a pressure-sensitive adhesive. As the pressure-sensitive adhesive used for the self-adhesive layer 7, a natural rubber pressure-sensitive adhesive is most preferable, but an acrylic pressure-sensitive adhesive, a synthetic rubber pressure-sensitive adhesive, a silicone rubber pressure-sensitive adhesive, etc. may also be used. The amount and thickness of the pressure-sensitive adhesive to form the self-adhesive layer 7 are not particularly limited, but preferably the amount is 0.1 to 50 g/m ² and the thickness is 0.1 to 50 μm. In particular, a natural rubber pressure-sensitive adhesive has a relatively weak adhesive force and is relatively easy to adjust the adhesive force, so it is suitable for forming the self-adhesive layer 7. The self-adhesive layer 7 will not adhere unless layers of the same composition are superimposed on each other. Therefore, even if the self-adhesive layer 7 is placed on a table with the bottom side and the delivery slip 2a or the attachment slip 2b of the surface substrate 2 is filled in, there is little risk that the self-adhesive layer 7 will adhere to the table.

As shown in FIG. 1(c), the adhesive layer 7 is coated with a pressure-sensitive adhesive in stripes. Specifically, adhesive-coated portions 7a coated with a pressure-sensitive adhesive and non-adhesive portions 7b not coated with a pressure-sensitive adhesive are arranged alternately. In this embodiment, the laminated sheet 1 is rectangular in plan view and has sides Sa and Sb, which are short sides facing each other. The adhesive-coated portions 7a and non-adhesive portions 7b are formed to extend in an oblique direction with respect to the side Sa on the delivery slip 2a side or the side Sb on the mounting portion 2c side. The oblique direction means that the angle is not 0 degrees or 90 degrees, but is greater than 0 degrees and less than 90 degrees. When the planar shape of the laminated sheet 1 is rectangular as in this embodiment, being oblique with respect to the short sides Sa and Sb means being oblique with respect to the long sides of the laminated sheet 1. The extension directions of the adhesive-coated portions 7a and non-adhesive portions 7b do not change within one laminated sheet and are all in the same direction.

In the self-adhesive layer 7, the adhesive-applied portions 7a and the non-adhesive portions 7b are alternately arranged, so that the pressure-sensitive adhesive can be applied widely over the entire surface while keeping the amount of pressure-sensitive adhesive applied small. As described below, when attaching the laminated sheet (luggage tag) to the object to which it is to be attached, the attachment portion 2c is bent as if it were wrapped around, and the self-adhesive layers 7 of the lower layers of the attachment portion 2c are overlapped and bonded by applying pressure. At this time, if it is parallel (0 degrees) or perpendicular (90 degrees) to the side Sa or side Sb, the adhesive-applied portion 7a may be entirely contained in the opposing non-adhesive portion 7b, and the adhesive-applied portions 7a may not overlap each other. In this case, the adhesive-applied portion 7a, which has a relatively weak adhesive strength, cannot bond the opposing attachment portions 2c to each other. This makes it impossible to attach the baggage tag to the object to which it is to be attached.

The angle R formed by the direction in which the adhesive-applied portion 7a and the non-adhesive-applied portion 7b extend with the sides Sa and Sb must be greater than 0 degrees and smaller than 90 degrees (0<R<90). The angle R is preferably 30 degrees or more and 60 degrees or less (30≦R≦60), and more preferably 40 degrees or more and 50 degrees or less (40≦R≦50). If the angle R is too small or too large, the contact area between the adhesive-applied portions 7a when the mounting portions 2c are overlapped will not be stable, making it difficult to maintain the adhesive force required for mounting. In this embodiment, R = 45 degrees. The closer R is to 45 degrees, the more preferable it is. The angle R is calculated by converting it so that the minimum value is 0 degrees and the maximum value is 90 degrees. For example, if the angle that the adhesive-coated portion 7a and the non-adhesive-coated portion 7b make with the sides Sa and Sb can be said to be greater than 90 degrees but equal to 180 degrees, the angle is subtracted from 180 and converted to a value in the range of 0 to 90, and the resulting value is taken as angle R.

<3. Continuous sheet>
Next, a continuous sheet in which a plurality of individual laminated sheets 1 are connected will be described. FIG. 2 is a diagram showing a continuous sheet according to an embodiment of the present invention. The continuous sheet 10 according to this embodiment is a continuous sheet in which a plurality of laminated sheets 1 are connected with a side Sa, which is a short side on the delivery slip 2a side of a certain laminated sheet 1, and a side Sb, which is a short side on the attachment portion 2c side of an adjacent laminated sheet 1, as a single separation planned line 10a. The separation planned line 10a can be folded when the continuous sheet 10 is conveyed, and is finally separated into each individual laminated sheet 1, so it may be formed in any manner as long as it is separable. In this embodiment, the cuts and joints (cut portions and tie portions) are perforated in an alternating manner.

In addition, in the continuous sheet 10, the stretching directions of the adhesive-coated portions 7a and the adhesive-uncoated portions 7b are different between the odd-numbered laminate sheets 1 and the even-numbered laminate sheets 1. Hereinafter, the odd-numbered laminate sheets 1 will be described as laminate sheets 1a, and the even-numbered laminate sheets 1 as laminate sheets 1b. It is the same if the odd-numbered laminate sheets 1 are referred to as laminate sheets 1b, and the even-numbered laminate sheets 1 as laminate sheets 1a. When describing features common to both laminate sheets 1a and 1b, they may be collectively referred to as laminate sheets 1.

Figure 3 is an enlarged view of part B in Figure 2(b). As shown in Figure 3, in this embodiment, in both laminate sheets 1a and 1b, the width of adhesive-applied portion 7a is W1, and the width of non-adhesive-applied portion 7b is W2. In addition, the positions of adhesive-applied portion 7a of laminate sheet 1a and adhesive-applied portion 7a of laminate sheet 1b are shifted from each other on planned separation line 10a. Specifically, as shown in Figure 3, when the distance between the centers of adhesive-applied portion 7a of laminate sheet 1a in the width direction on planned separation line 10a is 2D, the distance between the centers of non-adhesive-applied portion 7b of laminate sheet 1b in the planned separation line 10a is also 2D, and the centers of adhesive-applied portion 7a of laminate sheet 1a in the width direction and the centers of non-adhesive-applied portion 7b are shifted from each other by D on planned separation line 10a.

When laminated sheets 1a and 1b are folded along planned separation line 10a so that the self-adhesive layers 7 face each other, the width W1 of adhesive-applied portion 7a, the width W2 of non-adhesive-applied portion 7b, and the distance D between the center of the width of adhesive-applied portion 7a of laminated sheet 1a and the center of the width of non-adhesive-applied portion 7b at planned separation line 10a can be set appropriately as long as the adhesive-applied portions 7a do not come into contact with each other. Taking into account errors during manufacturing, it is preferable that the width W2 of non-adhesive-applied portion 7b is 1 mm or more larger than the width W1 of adhesive-applied portion 7a. For example, the width W1 can be 1 (mm), the width W2 can be 3 (mm), and the distance D can be 2.8 (mm).

The continuous sheet 10 according to this embodiment is transported in the longitudinal direction before being separated into the individual laminated sheets 1. For example, when the laminated sheet 1 is a baggage tag used for airline baggage, the continuous sheet 10 is transported in a baggage tag issuing machine installed in an airport by a travel agency, a transportation company, or the like. In this case, the individual laminated sheets 1 are cut and taken out at the take-out port of the baggage tag issuing machine and handed over to the user. In the baggage tag issuing machine, there is a method of supplying the continuous sheet in a so-called rolled state by winding it around the central axis, or a method of supplying the continuous sheet in a so-called zigzag folded state for each laminated sheet 1. The zigzag folded state is a state in which each separation planned line 10a is folded alternately in the opposite direction. The continuous sheet 10 according to this embodiment is particularly suitable for the method of supplying the continuous sheet in a zigzag folded state. Even if the self-adhesive layers 7 are stored facing each other before being separated into the individual laminated sheets in the issuing machine, the possibility of the self-adhesive layers 7 adhering to each other is reduced.

In the continuous sheet 10 according to this embodiment, the adhesive-applied portions 7a of two adjacent laminated sheets 1 are formed to extend at angles symmetrical to each other with respect to the planned separation line 10a. Specifically, as shown in FIG. 3, when laminated sheets 1a and 1b are connected by the planned separation line 10a, the angle RA that the adhesive-applied portion 7a of laminated sheet 1a makes counterclockwise from the planned separation line 10a is equal to the angle RB that the adhesive-applied portion 7a of laminated sheet 1b makes clockwise from the planned separation line 10a.

The end of the adhesive-applied portion 7a in the laminated sheet 1a and the end of the adhesive-applied portion 7a in the laminated sheet 1b are formed at positions offset from each other along the planned separation line 10a. In one laminated sheet 1, all adhesive-applied portions 7a and non-adhesive-applied portions 7b are formed to be parallel. The width of the adhesive-applied portion 7a is narrower than the width of the non-adhesive-applied portion 7b. Therefore, when the laminated sheet 1a and the laminated sheet 1b are folded along the planned separation line 10a so that the self-adhesive layers 7 face each other, the adhesive-applied portions 7a do not come into contact with each other. Therefore, as shown in FIG. 2(a), when the continuous sheet 10 is conveyed by zigzag folding, the laminated sheets 1 facing each other do not adhere to each other, and can be conveyed well.

4. Production of continuous sheets and laminated sheets
The laminate sheet 1 according to the above embodiment is configured by laminating a first sheet composed of a surface substrate 2, a peeling layer 3, an adhesive layer 4, and an adhesive layer 8, and a second sheet composed of a sealing layer 5, a support substrate 6, and an adhesive layer 7. The continuous sheet 10 before being separated into individual laminate sheets 1 is also configured by laminating a first sheet composed of a surface substrate 2, a peeling layer 3, an adhesive layer 4, and an adhesive layer 8, and a second sheet composed of a sealing layer 5, a support substrate 6, and an adhesive layer 7. As described above, in the adhesive layer 7, all adhesive-coated portions 7a and adhesive-non-coated portions 7b corresponding to one laminate sheet are parallel, and between adjacent laminate sheets, they extend at angles RA and RB that are symmetrical to each other with respect to the separation planned line 10a, and the adhesive-coated portions 7a and adhesive-non-coated portions 7b are formed so that the end of the adhesive-coated portion 7a in one laminate sheet and the end of the adhesive-coated portion 7a in the adjacent laminate sheet 1b are shifted from the separation planned line 10a by a distance D from each other. Both the first sheet and the second sheet are formed by connecting a plurality of laminated sheets 1 together, and furthermore, each sheet is usually provided with a side piece in the conveying direction having a feed hole or the like for conveying.

First, the first sheet is perforated to form a division line 9b, which is a perforation that penetrates the surface base material 2. Then, the first sheet and the second sheet are overlapped and pasted together so that the four corners of each laminated sheet are aligned. Next, half-cut processing is performed from the surface base material 2 side of the first sheet to form a separation planned line 9a, which is a cut that penetrates the surface base material 2 and does not reach the support base material 6. Furthermore, perforation processing is performed to form a separation planned line 10a, which is a perforation that penetrates the first sheet and the second sheet, between each laminated sheet. This results in a continuous sheet 10 as shown in Figure 2.

The continuous sheet 10 is supplied and transported in a state where it is folded so that the self-adhesive layers 7 of adjacent laminated sheets 1 face each other, with the planned separation line 10a as the folding line. Then, at a specified timing or based on an instruction, the continuous sheet 10 is separated at the planned separation line 10a to obtain individual laminated sheets 1. For example, as shown in FIG. 2(a), the continuous sheet 10 is set in a baggage tag issuing machine installed in an airport in a so-called zigzag folded state. Then, at the take-out port of the baggage tag issuing machine, the individual laminated sheets 1 are cut and discharged. In this way, the user can obtain the individual laminated sheets 1.

<5. Examples of use of laminated sheets>
Next, an example of the use of the laminated sheet according to this embodiment will be described. Here, a case where the laminated sheet 1 is used as a baggage tag at an airport will be described. First, as described above, the laminated sheet 1 separated from the continuous sheet 10 is obtained by a baggage tag issuing machine installed in an airport by a transportation company or a travel agency. In the delivery information section of the laminated sheet 1, delivery information such as the address and name of both the recipient and the sender is printed and output by a printer in the baggage tag issuing machine. This results in the laminated sheet 1 as shown in FIG. 1 being obtained. When the delivery information is not printed and needs to be written, or when information other than the delivery information needs to be written, the user can write information on the delivery slip 2a, the attachment slip 2b, etc. at any time. In such a laminated sheet 1, the bottom layer on the side opposite the surface base material 2 is the self-adhesive layer 7. This self-adhesive layer 7 does not adhere unless layers of the same composition are overlapped, so it is difficult to adhere to other objects as it is. Therefore, when writing on the delivery slip 2a or the attachment slip 2b, writing can be done without worrying about the bottom layer adhering, as with ordinary paper.

Figure 4 is a diagram showing an example of the use of a laminated sheet according to one embodiment of the present invention. Here, a case where the laminated sheet of this embodiment is used as a baggage tag to be attached to baggage such as delivery items will be described. Figure 4(a) shows a delivery item H such as a travel bag, Figure 4(b) is an enlarged view of a handle T in Figure 4(a), and Figure 4(c) is a cross-sectional view corresponding to C-C of the laminated sheet wrapped around the handle T in Figure 4(b). Note that in Figure 4(c), in order to show a simplified wrapping state, the peeling layer 3, adhesive layer 4, and sealing layer 5 are omitted, and only the attachment slip 2b, mounting portion 2c, support substrate 6, and self-adhesive layer 7 of the surface substrate 2 are shown.

After completing the delivery slip 2a and the attachment slip 2b, the user wraps the attachment part 2c around the attachment target. The attachment target needs to be large enough to fit within the width of the attachment part 2c when folded in half. For example, the attachment target may be the handle T of a delivery item H as shown in FIG. 4. The user bends the attachment part 2c so as to wrap it around a relatively thin handle T, such as a rod-shaped handle T having a longitudinal direction, overlaps the self-adhesive layers 7 of the lower layers of the attachment part 2c, and applies pressure. This pressure can be as strong as a person would lightly grip it. This pressure causes the self-adhesive layers 7 to adhere to each other. At this time, the self-adhesive layers 7 do not adhere to the handle T itself. For this reason, the attachment part 2c is in a state of being wrapped around the handle T, as shown in FIG. 4(b) and (c).

Figure 5 shows the state in which the self-adhesive layers 7 are overlapped. Figure 5(a) shows the state when folded along a line parallel to the division line 9b, and Figure 5(b) shows the state when folded at an angle inclined from the division line 9b. When the angle R between sides Sa and Sb is 45 degrees, when folded along a line parallel to the division line 9b, as shown in Figure 5(a), the overlapping part of the adhesive-applied parts 7a of the two laminated sheets 1 (hatched part in the figure) becomes nearly square in shape, and the adhesive strength is strengthened. This allows the laminated sheet 1 to be stably fixed to baggage, etc.

However, when the laminated sheet 1 is used as a baggage tag, the user does not necessarily carefully fold it along a line parallel to the division line 9b, and may simply overlap the self-adhesive layers 7. In this case, if the laminated sheet 1 is folded at an angle inclined from the division line 9b, the overlapping portions of the adhesive-coated portions 7a of the two laminated sheets 1 will be rhombus-shaped, as shown in FIG. 5(b), and the adhesive strength will be weakened. Nevertheless, since the adhesive-coated portions 7a are formed to extend diagonally with respect to the short sides Sa and Sb of the laminated sheet 1, even if the laminated sheet 1 is folded carelessly, overlapping portions 7c will always be formed and the self-adhesive layers 7 will be bonded together. In this way, the adhesive-coated portions 7a coated with pressure-sensitive adhesive and the non-adhesive portions 7b without pressure-sensitive adhesive are alternately formed to extend diagonally with respect to one side of the laminated sheet 1, so that the self-adhesive layer 7 can be fixed to an object such as a delivery item H even if the laminated sheet 1 is folded carelessly.

In this way, the laminated sheet 1 with the delivery destination written on it is attached to the delivery item H, and it is delivered to the delivery destination. After the delivery item H is delivered, the delivery slip 2a is peeled off from the laminated sheet 1. As described above, when the laminated sheet 1 is used as a baggage tag, the bottommost self-adhesive layer 7 normally has low viscosity and does not easily adhere to other objects, so there is little hindrance to writing on it. For this reason, after writing on it, it can be attached by wrapping it around a relatively thin part such as a handle by simply pressing it on itself. This eliminates the need to peel off the release paper covering the adhesive layer after writing on it, as with conventional baggage tags and delivery slips. In addition, the release paper itself is no longer necessary, which contributes to resource conservation.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and various modifications are possible. For example, in the above embodiment, perforations are formed as the division line 9b, but a cut that penetrates the surface base material 2 and does not reach the support base material 6 may be formed as a half cut on the laminated sheet 1. Also, instead of processing the surface base material 2 itself like perforations or cuts, the division line 9b may be formed by printing a visible line. It is also possible not to form the division line 9b itself. When the division line 9b is not formed, the end of the delivery information column printed on the surface of the attachment slip 2b opposite the delivery slip 2a functions as the attachment portion 2c.
