Description

[Technical Field]

[0001] The present invention relates to information-transmitting labels and articles. [Background technology]

[0002] Some information transmission labels are required to be easily peelable from the printing substrate on the label surface after being attached to an adherend with a pressure-sensitive adhesive or adhesive, and a pseudo-adhesive layer is provided to facilitate peeling. Examples of information transmission labels that are required to be easily peelable from the printing substrate on the surface include delivery slips and information concealment labels.

[0003] A delivery slip is a printing substrate on which information regarding the delivery destination, delivery origin, delivery contents, etc. is written so that delivery companies can manage goods and deliveries when delivering various goods such as merchandise. The delivery slip is then adhered to the goods to be attached via a pseudo-adhesive layer. Then, when delivery is completed, the printing substrate on which the delivery information is written is peeled off.

[0004] As an example of information transmission labels used on such delivery slips, Patent Document 1 discloses a delivery slip paper in which label paper is provided on the pseudo-adhesive layer side of pseudo-adhesive paper, and an adhesive and release paper are sequentially laminated on the opposite side of the pseudo-adhesive layer. Patent Document 2 also discloses a rectangular delivery slip having a pseudo-adhesive structure in which, in the thickness direction, a printing base paper, an adhesive layer, a support substrate, an adhesive layer, and release paper are provided, and part of the printing base paper is peelable, and the delivery slip is characterized in that the adhesive layer is provided on the upper side with an adhesive layer non-forming area where the adhesive layer is recessed from the upper side to the lower side. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-038488 [Patent Document 2] Japanese Patent Application Publication No. 2018-079647 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with conventional information transmission labels, such as the delivery slips described in Patent Documents 1 and 2, the print substrate may not be easily and cleanly peeled off. While conventional information transmission labels incorporate certain features for peeling, such as reducing adhesive strength by providing a pseudo-adhesive layer, users may have difficulty gripping the print substrate properly or the print substrate may peel off in an unintended location when peeling it off. In particular, with delivery slips and the like, the print substrate is often peeled off while wearing gloves, which prevents delicate gripping movements with the fingertips, making such problems more likely to occur. Furthermore, when peeling off the print substrate, the print substrate may peel off with the adhesive layer still attached, or peel off in a manner that destroys the surface of the substrate. This can cause inconvenience when the peeled print substrate sticks to other print substrates or damage the packaging material of the package when the peeled print substrate is taken home.

[0007] The present invention has been made in consideration of the above circumstances, and its object is to provide an information transmission label and article that allows the printing substrate to be easily peeled off and that can prevent peeling of the printing substrate at unintended interfaces, etc. [Means for solving the problem]

[0008] As a result of intensive research into achieving the above-mentioned object, the inventors have discovered a label for transmitting information comprising a printable substrate layer, an adhesive layer, and a pseudo-adhesive layer disposed between the printable substrate layer and the adhesive layer, wherein a non-adhesive end is formed on at least a part of the end of the adhesive layer, and a fracture line is provided on the surface of the printable substrate layer, the fracture line having a depth that reaches from the printable substrate layer to at least the pseudo-adhesive layer, so that, in a cross-sectional view of the information transmission label, cutting can be guided from the non-adhesive end toward the printable substrate layer. This has led to the completion of the present invention.

[0009] That is, the present invention is as follows.

[0010] (1) This information transmission label includes a printable substrate layer, an adhesive layer, and a pseudo-adhesive layer disposed between the printable substrate layer and the adhesive layer, wherein a non-adhesive end is formed on at least a portion of the end of the adhesive layer, and a break line is provided on the surface of the printable substrate layer to a depth that reaches from the printable substrate layer to at least the pseudo-adhesive layer, so that, in a cross-sectional view of the information transmission label, cutting can be guided from the non-adhesive end toward the printable substrate layer. (2) The information transmission label according to (1), wherein a release liner layer is disposed on the surface of the pressure-sensitive adhesive layer opposite to the pseudo-adhesive layer side. (3) The information transmission label according to (1) or (2), wherein the non-adhesive end portion is a portion that has been subjected to adhesive-blocking treatment. (4) The information transmission label according to (1) or (2), wherein the non-adhesive end is a portion to which no adhesive is applied. (5) The information transmission label is described in any one of (1) to (4), wherein the breaking line is located within an area of ​​0 mm to 5 mm from the inner edge of the non-adhesive end when viewed from above the information transmission label. (6) The information transmission label described in any one of (1) to (5) is such that the breaking line is a perforation in which cut and uncut portions are arranged continuously, and the ratio of the length of the cut portion to the length of the uncut portion is 3:1 to 1:3. (7) An article in which an information transmission label comprising a printable substrate layer, an adhesive layer, and a pseudo-adhesive layer disposed between the printable substrate layer and the adhesive layer is affixed to the surface of an object to be adhered, wherein the adhesive layer has a non-adhesive end portion formed on at least a portion of the end portion of the surface opposite the printable substrate layer, and the surface of the printable substrate layer has a fracture line that is deep enough to reach at least the pseudo-adhesive layer from the printable substrate layer so that, in a cross-sectional view of the information transmission label, the label can be guided to tear from the non-adhesive end portion toward the printable substrate layer. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide an information transmission label and an article in which the printable substrate can be easily peeled off and peeling at unintended interfaces or the like of the printable substrate can be suppressed.

The following present embodiment is an example for explaining the present invention, and is not intended to limit the present invention to the following content. The present invention can be carried out by appropriately modifying it within the scope of its gist.

[0015] Furthermore, in this specification, terms with "abbreviation" attached indicate the meaning of the term excluding "abbreviation" within the scope of common technical knowledge of a person skilled in the art, and also include the meaning itself excluding "abbreviation."

[0016] The information transmission label according to the present embodiment includes a printable substrate layer, an adhesive layer, and a pseudo-adhesive layer disposed between the printable substrate layer and the adhesive layer.

[0017] First Embodiment

[0018] Fig. 1 is a cross-sectional view of the information transmission label with a release liner according to the first embodiment, and Fig. 2 and Fig. 3 are schematic diagrams illustrating an example of how the information transmission label with a release liner according to the first embodiment is used. Fig. 4 is a schematic top view of the information transmission label with a release liner according to the first embodiment.

[0019] The information transmission label 1 with a release liner includes a printable substrate layer 101, an adhesive layer 103, and a pseudo-adhesive layer 102 disposed between the printable substrate layer 101 and the adhesive layer 103. The adhesive layer 103 is provided with an adhesive-blocking portion 104 that can serve as a starting point for peeling. In addition, when viewed from above, the printable substrate layer 101 is provided with a breaking line 105 that allows for cutting guidance.

[0020] (Printing base material layer)

[0021] A printable or printable substrate can be used as the print substrate layer 101. For example, if the information transmission label 10 is a delivery slip, the information to be printed on the print substrate layer 101 may include information about the sender, destination, and delivery company (such as name, address, residence, and telephone number), as well as the contents of the delivery item.

[0022] Examples of the print substrate layer 101 include paper, resin film, synthetic paper, and laminated sheets formed by laminating two or more of these. Examples of papers include thermal paper, thermal transfer printing paper, pressure-sensitive paper, inkjet paper, laser printer paper, kraft paper, fine paper, glassine paper, rayon paper, coated paper, and synthetic fiber paper. Examples of resin films include films of polyester resin, polyvinyl chloride resin, polyvinylidene chloride resin, and polyolefin resin. The resin film may have a coating layer on the surface opposite the pseudo-adhesive layer 102. Examples of synthetic paper include paper made primarily from polyester resin, polyvinyl chloride resin, polyvinylidene chloride resin, and polyolefin resin. Among these, thermal paper, kraft paper, fine paper, and glassine paper are more preferred as the print substrate layer 101.

[0023] The thickness of the printable substrate layer 101 can be selected appropriately depending on the application of the information transmission label 10, but from the viewpoint of ease of handling, it is preferably 10 μm or more and 200 μm or less, more preferably 20 μm or more and 150 μm or less, and even more preferably 30 μm or more and 100 μm or less.

[0024] The basis weight of the print substrate layer 101 can be selected appropriately depending on the application of the information transmission label 10. 2 More than 100g / m 2 Preferably, it is 15 g / m or less. 2 More than 80g / m 2 More preferably, it is:

[0025] (pseudo adhesive layer)

[0026] The "pseudo-adhesion" (sometimes referred to as "pseudo-adhesion") of the pseudo-adhesive layer 102 refers to an adhesion that can be easily peeled at the interface between one layer and the other layer that are bonded under specific conditions (e.g., material combination, temperature range, and pressure), or within the pseudo-adhesive layer 102, and that does not exhibit re-adhesion or re-stickiness after peeling. Examples of information transmission labels 10 include those that can be peeled at the interface between the printable substrate layer 101 as one layer and the pseudo-adhesive layer 102 as the other layer, and the interface-side surfaces of the printable substrate layer 101 and the pseudo-adhesive layer 102 after peeling do not exhibit re-adhesion or re-stickiness. Even when peeling occurs within the pseudo-adhesive layer 102, the pseudo-adhesive layers 102 do not exhibit re-adhesion or re-stickiness between themselves. The pseudo-adhesive layer 102 is preferably laminated directly on the printable substrate layer 101. The pseudo-adhesive layer 102 may be made of, for example, a material containing a thermoplastic resin as a main component.

[0027] Examples of the thermoplastic resin contained in the pseudo-adhesion layer 102 include polyolefin-based resins, polyester-based resins, and polyamide-based resins. The pseudo-adhesion layer 102 may contain one type of thermoplastic resin or two or more types of thermoplastic resins.

[0028] The thermoplastic resin contained in the pseudo-adhesive layer 102 is preferably a polyolefin-based resin. A polyolefin-based resin is a polymer having at least a structural unit derived from an olefin monomer. The olefin monomer is preferably an olefin having 2 to 8 carbon atoms. Examples of olefins having 2 to 8 carbon atoms include ethylene, propylene, butylene, isobutylene, and 1-hexene; ethylene, propylene, and butylene are more preferred; and ethylene and propylene are even more preferred. The polyolefin-based resin may be a polymer using one type of olefin monomer alone, or a copolymer using two or more types of olefin monomers in combination.

[0029] Examples of polyolefin resins include polyethylene resins, polypropylene resins, polybutene resins, ethylene-propylene copolymers, olefin elastomers (TPO), ethylene-vinyl acetate copolymers (EVA), ethylene-methyl methacrylate copolymers (EMMA), and olefin terpolymers such as ethylene-propylene-(5-ethylidene-2-norbornene). Copolymers containing not only structural units derived from olefins but also structural units containing polar moieties, such as EVA and EMMA, can also be used. Among these, the polyolefin resin is preferably at least one resin selected from the group consisting of polyethylene resins, polypropylene resins, polybutene resins, and ethylene-vinyl acetate copolymers, and more preferably at least one resin selected from the group consisting of polyethylene resins, polypropylene resins, and ethylene-vinyl acetate copolymers.

[0030] The content of olefin-derived structural units in a polyolefin-based resin varies depending on the type of resin used, etc., but is preferably 50% by mass or more and 100% by mass or less, more preferably 60% by mass or more and 100% by mass or less, even more preferably 70% by mass or more and 100% by mass or less, even more preferably 80% by mass or more and 100% by mass or less, and even more preferably 85% by mass or more and 100% by mass or less, relative to the total structural units of the olefin-based resin (100% by mass).

[0031] Examples of polyethylene resins include ultra-low density polyethylene (VLDPE, density: 880 kg / m 3 More than 910kg / m 3 less than 910 kg / m 3 More than 915kg / m 3 less than 915 kg / m 3 More than 942kg / m 3 less than 942 kg / m 3 and linear polyethylene, etc. can be used.

[0032] In the case of an ethylene-vinyl acetate copolymer, for example, the content of structural units derived from vinyl acetate is preferably 3% by mass or more and 15% by mass or less, more preferably 4% by mass or more and 12% by mass or less, and even more preferably 5% by mass or more and 9% by mass or less, relative to all structural units of the copolymer (100% by mass).

[0033] The pseudo-adhesion layer 102 may contain one type of polyolefin resin as the thermoplastic resin, or may contain two or more types of polyolefin resin.

[0034] When the printing substrate layer 101 is a paper substrate, from the viewpoint of realizing good pseudo-adhesion with the paper substrate and from the viewpoint of easy thermocompression bonding to the paper substrate, it is preferable that the thermoplastic resin contained in the pseudo-adhesion layer 102 is at least one of polyethylene-based resin, polypropylene-based resin, and ethylene-vinyl acetate copolymer.

[0035] The pseudo-adhesion layer 102 may contain additives to the extent that the effects of this embodiment are not impaired. Examples of additives include antioxidants, lubricants, UV absorbers, colorants, and antiblocking agents. The additives may be used alone or in combination of two or more.

[0036] When the pseudo-adhesive layer 102 contains an additive, the content of the additive is preferably 0.0001 parts by mass or more and 25 parts by mass or less, more preferably 0.0005 parts by mass or more and 20 parts by mass or less, and even more preferably 0.001 parts by mass or more and 15 parts by mass or less, per 100 parts by mass of the thermoplastic resin.

[0037] The thickness of the pseudo-adhesion layer 102 is not particularly limited. The thickness of the pseudo-adhesion layer 102 is preferably 5 μm or more and 50 μm or less, more preferably 5 μm or more and 40 μm or less, even more preferably 10 μm or more and 40 μm or less, and even more preferably 10 μm or more and 30 μm or less. Furthermore, for example, when the pseudo-adhesion layer 102 contains a polyolefin resin, the thickness of the pseudo-adhesion layer 102 is particularly preferably 10 μm or more and 25 μm or less.

[0038] (Adhesive layer)

[0039] The adhesive layer 103 is a layer for adhering the information transmission label 10 to the adherend 30 (see FIG. 8 ) and is composed of, for example, an acrylic adhesive, a natural rubber adhesive, a synthetic rubber adhesive, a silicone adhesive, or the like. Among these, acrylic adhesives and synthetic rubber adhesives are preferred from the viewpoints of ease of adhesive strength control and economy. Examples of acrylic adhesives include solvent-based acrylic adhesives, aqueous emulsion-based acrylic adhesives, and hot-melt acrylic adhesives. Examples of synthetic rubber-based adhesives include solvent-based synthetic rubber adhesives, aqueous emulsion-based synthetic rubber adhesives, and hot-melt synthetic rubber adhesives.

[0040] The adhesive layer 103 may contain a tackifying resin (sometimes referred to as a tackifier, etc.). The tackifying resin can be selected appropriately depending on the application of the information transmission label 10. Examples of the tackifying resin include rosin-based resins, terpene-phenolic resins, terpene resins, aromatic hydrocarbon-modified terpene resins, aliphatic petroleum resins, aromatic petroleum resins, hydrogenated petroleum resins, coumarone-indene resins, styrene-based resins, phenolic resins, and xylene resins.

[0041] The adhesive layer 103 may contain additives as needed. Examples of additives include fillers, softeners, heat and light stabilizers, antioxidants, and crosslinking agents. Examples of fillers include zinc oxide, titanium oxide, silica, calcium carbonate, and barium sulfate. Examples of softeners include process oil, liquid rubber, and plasticizers. Examples of heat and light stabilizers include benzophenone-based stabilizers, benzotriazole-based stabilizers, and hindered amine-based stabilizers. Examples of antioxidants include anilide-based antioxidants, phenol-based antioxidants, phosphite-based antioxidants, and thioester-based antioxidants.

[0042] The thickness of the adhesive layer 103 can be selected appropriately depending on the application of the information transmission label 10. The thickness of the adhesive layer 103 is preferably 5 μm or more and 50 μm or less, more preferably 10 μm or more and 50 μm or less, even more preferably 10 μm or more and 40 μm or less, even more preferably 10 μm or more and 30 μm or less, and even more preferably 10 μm or more and 25 μm or less.

[0043] (Glue-killing part)

[0044] The adhesive-blocking portion 104 as the non-adhesive end portion only needs to be treated so as not to adhere to at least the release liner layer 11. For example, it can be formed by coating or applying a non-adhesive material to the adhesive layer 103. Adhesive-blocking can be performed, for example, after the information transmission label 10 is formed and before punching or other processes are performed. Specifically, the adhesive-blocking portion 104 is formed by applying a non-adhesive material to an end portion of one side of the adhesive layer 103 that is exposed when the release liner layer 11 is peeled from the adhesive layer 103. The release liner layer 11 is then reattached to the adhesive layer 103. Alternatively, the adhesive-blocking portion 104 may be formed by applying a non-adhesive material to an end portion of one side of the adhesive layer 103 before laminating the release liner layer 11 to the adhesive layer 103. The non-adhesive material used for adhesive-blocking is not particularly limited, but examples include non-adhesive resin materials (printing ink, varnish, kill film, polyolefin film, polyester film, etc.). The adhesive-blocking portion 104 functions as a handle, a peeling opening, etc. when peeling off the print base layer 101, and can be used as a starting point for peeling.

[0045] The width w of the adhesive-blocking portion 104 is not particularly limited, but from the viewpoint of achieving both ease of peeling of the adhesive-blocking portion 104 and resistance to peeling of the information-transmitting label 10 from the adherend 30 (see FIG. 8), it is preferably 1 mm to 20 mm, more preferably 3 mm to 18 mm, and even more preferably 5 mm to 15 mm. A width of 1 mm or more allows the user to easily grasp the label, while a width of 20 mm or less effectively prevents the information-transmitting label 10 from unintentionally peeling from the release liner layer 11 or the adherend 30.

[0046] (Broken line)

[0047] The break line 105 is provided on the surface of the print substrate layer 101, and its depth reaches from the print substrate layer 101 to at least the pseudo-adhesive layer 102. By providing such a break line 105, advantages include making it easier to fold the end at the exact intended folding position (desired position) during peeling, and being able to guide the pseudo-adhesive layer 102 to be cut toward the print substrate layer 101 (upward; see arrow F1). Specifically, by starting from the non-adhesive end, the glue-blocking portion 104, and pulling it upward (see arrow F1), it is possible to guide the cutting from the non-adhesive end, the glue-blocking portion 104, toward the print substrate layer 101 (see arrow F1). The break line 105 can be, for example, a perforation.

[0048] In other words, if the break line 105 does not satisfy these conditions, it is difficult to bend the end at the desired position when attempting to peel it off. It is also difficult to separate the pseudo-adhesive layer 102 at the desired position. For example, unintentional partial peeling may occur between the adhesive layer 103 and the adherend 30, or the adhesive may stick to the peeled label. Furthermore, if the surface of the adherend 30 is weak, the surface of the adherend 30 may be torn. In this regard, the configuration of this embodiment can prevent such problems from occurring.

[0049] 2 and 3, an example of how the printable substrate layer 101 is peeled off from the information-transmitting label 10 attached to the adherend 30 will be described in detail. First, as a starting point for peeling the printable substrate layer 101 from the information-transmitting label 10, a finger is inserted into the adhesive-blocking portion 104, which is the non-adhesive end of the adhesive layer 103, and the layer is grasped (or the finger may be inserted to make the layer stand up). Next, the layer is pulled upward (see arrow F1) from the adhesive-blocking portion 104, and is cut along a nearby fracture line 105. When the cut reaches the interface L1 between the information-transmitting label 10 and the pseudo-adhesive layer 102, the printable substrate layer 101 can be peeled off from there along the interface L1 (along the horizontal direction in FIGS. 2 and 3). In this way, the printing substrate layer 101 is peeled off while the pseudo-adhesive layer 102a at the end of the pseudo-adhesive layer 102, the adhesive layer 103a at the end of the adhesive layer 103, and the glue-killing portion 104 remain attached to the printing substrate layer 101 (see Figure 3).

[0050] Furthermore, by forming the break line 105 on the surface facing the print substrate layer 101, the position of the break line 105 can be easily visually confirmed (see FIG. 4). This also makes it easy to peel off the print substrate layer 101. In this regard, if a break line or slit is formed on the back surface of the print substrate layer 101, for example, the user may not be able to visually identify the starting point for peeling, which may cause problems such as not knowing where and how to peel in order to peel off the print substrate layer 101 cleanly. Furthermore, since the break line 105 extends to the print substrate layer 101, the print substrate layer 101 can be easily bent, making it easy to use as a handle when peeling.

[0051] The printable substrate layer 101 is not necessarily peeled off along the interface L1 between the information transmission label 10 and the pseudo-adhesive layer 102. For example, the printable substrate layer 101 may be peeled off so as to divide the pseudo-adhesive layer 102 in half in a cross-sectional view (see interface L2). To facilitate peeling the pseudo-adhesive layer 102 in half, for example, the pseudo-adhesive layer 102 may be designed to be formed into two layers, with the interface L2 between the layers. In addition, the pseudo-adhesive layer 102 may be designed to facilitate cohesive failure by being a layer containing wax particles (e.g., paraffin wax; polyolefin waxes such as polyethylene and polypropylene; metal soap waxes such as zinc stearate, calcium stearate, zinc ricinoleate, and zinc octoate; stearic acid wax; carnauba wax; Montan acid ester wax, etc.) and a binder resin (e.g., styrene-butadiene rubber (SBR), acrylonitrile-butadiene rubber (NBR), acrylic resin, styrene resin, polyvinyl alcohol (PVA) resin, etc.).

[0052] From the viewpoint of enabling cutting guidance by the break line 105, it is preferable to control the distance d (see FIG. 4) between the break line 105 and the inner edge 1041 of the adhesive-binding portion 104 when viewed from above the information transmission label 10. Specifically, it is preferable that the break line 105 be located within an area of ​​0 mm to 5 mm from the inner edge 1041 of the adhesive-binding portion 104, which is the non-adhesive end, when viewed from above the information transmission label 10. Note that the "inside" here refers to the direction approaching the center of gravity within the surface when viewed from above the information transmission label 10, and the "outside" refers to the direction opposite to the inside.

[0053] For example, Figure 4 illustrates an example in which the break line 105 is positioned inside the inner edge 1041 of the glue-killing portion 104 (see arrow F2), but it may also be positioned outside (i.e., between the inner edge 1041 and the outer edge 1042).

[0054] As described above, the distance d is preferably 0 mm or more and 5 mm or less, more preferably 0 mm or more and 3 mm or less, and even more preferably 1 mm or more and 2 mm or less, which allows for easier cutting guidance from the adhesive-blocking portion 104 toward the print substrate layer 101 (see arrow F1).

[0055] The depth of the break line 105 may be any depth that reaches from the printing substrate layer 101 to at least the pseudo-adhesive layer 102, but the appropriate depth can be determined taking into consideration the configuration of the non-adhesive end portion and the positional relationship between the break line 105 and the non-adhesive end portion, etc.

[0056] For example, as in the first embodiment, when the non-adhesive end portion is formed by subjecting the adhesive layer 103 to a glue-blocking treatment, the depth of the rupture line 105 can be set to a depth that reaches from the print base material layer 101 to the adhesive layer 103. For example, when the rupture line 105 is located inside the inner edge 1041 of the glue-blocking portion 104, which is the non-adhesive end portion, in a top view (see FIG. 4), the rupture line 105 can be set to a depth that reaches from the print base material layer 101 to the adhesive layer 103. Furthermore, when the rupture line 105 is located within the region of the glue-blocking portion 104, which is the non-adhesive end portion, in a top view (not shown), the rupture line 105 can be set to a depth that reaches from the print base material layer 101 to the adhesive layer 103a (see FIG. 3).

[0057] The rupture line 105 is, for example, a perforation in which cut portions and uncut portions are continuously arranged, and the ratio of the length c of the cut portion to the length u of the uncut portion is preferably 3:1 to 1:3, more preferably 2:1 to 1:2, and even more preferably 2:1 to 1:1. By setting the ratio of the length c of the cut portion to the length u of the uncut portion within the above range, it is possible to prevent the print substrate layer 101 from being cut when peeling it off, and it is possible to more easily induce cutting of the pseudo-adhesive layer 102 and the like by the perforation.

[0058] For example, by making the ratio of the length c of the cut portion to the length u of the uncut portion shorter than 3:1, it is possible to effectively prevent problems such as excessive perforation, which would otherwise result in the printing substrate layer 101 itself being cut when peeling it off.

[0059] Furthermore, by making the length c of the cut portion longer than 1:3 with respect to the ratio of the length c of the cut portion to the length u of the uncut portion, the perforations may not be deep enough, and when the adhesive is pulled upward from the glue-killing portion 104 (see arrow F1), the perforations may not adequately guide the cutting, resulting in a cross section that looks like the pseudo-adhesive layer 102 has been torn off, making it impossible to cut cleanly. This can effectively prevent such problems.

[0060] The length c of the cut portion is not particularly limited, but is preferably 0.1 mm to 5 mm, more preferably 0.5 mm to 4 mm, even more preferably 1 mm to 3 mm, and even more preferably 1 mm to 2 mm. Furthermore, for example, in the case of microperforations, the length c is preferably 0.1 mm to 0.5 mm.

[0061] The length u of the uncut portion is not particularly limited, but is preferably 0.1 mm to 5 mm, more preferably 0.5 mm to 4 mm, even more preferably 1 mm to 3 mm, and even more preferably 1 mm to 2 mm. Furthermore, for example, in the case of microperforations, it is preferably 0.1 mm to 0.5 mm.

[0062] As shown in Fig. 4, the release-liner information transmission label 1 is rectangular, and has adhesive-retaining portions 104 and break lines 105 formed substantially parallel to a pair of opposing edges. While Fig. 4 illustrates an example in which the adhesive-retaining portions 104 and break lines 105 are formed on the edges of two of the four opposing sides, it goes without saying that this embodiment also encompasses other embodiments, such as those in which the adhesive-retaining portions 104 and break lines 105 are formed on only one edge, or those in which the adhesive-retaining portions 104 and break lines 105 are formed on the edges of three sides. Thus, according to this embodiment, the arrangement, shape, number, and relative positions of the adhesive-retaining portions 104 and break lines 105, which are the non-adhesive ends, are not limited to those shown in Fig. 4, and suitable conditions can be selected as appropriate depending on the manner in which the information transmission label 10 is used.

[0063] FIG. 5 is a top view of an information-transmitting label with a release liner according to the first embodiment, showing a modified non-adhesive edge and break line.

[0064] The information transmission label 1a with a release liner shown in Fig. 5 is rectangular, and has adhesive-binding portions 104 and breaking lines 105 formed approximately parallel to two pairs of opposing edges. In other words, the adhesive-binding portions 104 and breaking lines 105 are formed along the four periphery.

[0065] FIG. 6 is a schematic top view of another modified example of the arrangement of the non-adhesive end and the break line in the information-transmitting label with a release liner according to the first embodiment.

[0066] The information transmission label 1b with a release liner shown in Fig. 6 is rectangular, and has approximately quarter-circular adhesive-binding portions 104 and approximately arc-shaped breaking lines 105 formed around the four corners. That is, the adhesive-binding portions 104 and breaking lines 105 are formed at the four corners.

[0067] (Release liner layer)

[0068] The release liner layer 11 is disposed on the surface of the adhesive layer 103 opposite to the pseudo-adhesive layer 102. The release liner layer 11 may be made of any material as long as it can be peeled off from the adhesive layer 103. For example, when the information transmission label 10 according to this embodiment is used as a delivery slip, the delivery slip paper becomes an information transmission label 1 with a release liner, in which the release liner layer 11 is laminated on the adhesive layer 103, and when the delivery slip paper is to be attached to an adherend 30 such as a package, the release liner layer 11 is peeled off from the adhesive layer 103, and the surface of the adhesive layer 103 is attached to the surface of the adherend 30, etc.

[0069] Furthermore, as long as the effects of this embodiment can be obtained, the information transmission label 10 may be provided with other functional layers as needed, such as a vapor deposition layer and a concealing layer.

[0070] (Manufacturing method)

[0071] The information transmission label 10 can be produced by a known method, for example, by a production method including the steps of (i) pseudo-adhering a pseudo-adhesive layer 102 to a printable substrate layer 101 to obtain a laminate, and (ii) laminating a pressure-sensitive adhesive layer 103 on the pseudo-adhesive layer 102 of the laminate.

[0072] As a method for obtaining the laminate in step (i), for example, a step of melt-extruding the material of the pseudo-adhesive layer 102 onto the print substrate layer 101 using a T-die or the like can be employed. After the melt-extrusion step, a cooling step using a cooling roll or air cooling may be performed as necessary.

[0073] As a method for laminating the pressure-sensitive adhesive layer 103 in step (ii), for example, a step of forming the pressure-sensitive adhesive layer 103 by applying a pressure-sensitive adhesive composition to the surface of the pseudo-adhesive layer 102 of the laminate can be employed. Examples of methods for applying the pressure-sensitive adhesive composition include roll coating, spray coating, bar coating, knife coating, roll knife coating, blade coating, die coating, and gravure coating. Furthermore, from the viewpoint of improving the adhesion between the pseudo-adhesive layer 102 and the pressure-sensitive adhesive layer 103, it is preferable to form the pressure-sensitive adhesive layer 103 after subjecting the surface of the pseudo-adhesive layer 102 to a corona treatment or the like.

[0074] When producing an information transmission label 1 with a release liner, the release liner described above can be laminated on the surface of the adhesive layer 103. Alternatively, the label can be produced by forming the adhesive layer 103 on the release liner side, and then bonding the adhesive layer 103 to the surface of the pseudo-adhesive layer 102 of the laminate produced in step (i).

[0075] Second Embodiment

[0076] FIG. 7 is a cross-sectional view of an information-transmitting label with a release liner according to the second embodiment.

[0077] The information-transmitting label 2 with a release liner according to the second embodiment is formed by laminating a release liner layer 11 on an information-transmitting label 20 having a non-adhesive end portion constituted by a non-coated portion 204 where no adhesive is applied. That is, the second embodiment has an area where the adhesive is applied (see adhesive layer 203) and an area where the adhesive is not applied (see non-coated portion 204), thereby controlling the label so as not to adhere to at least the release liner layer 11. Of course, the label may also be controlled so as not to adhere to both the release liner layer 11 and the pseudo-adhesive layer 102.

[0078] The second embodiment differs from the first embodiment in that the non-adhesive end portion is a non-coated portion 204. That is, the second embodiment is similar to the printable substrate layer 101, pseudo-adhesive layer 102, release liner layer 11, and rupture line 105 of the first embodiment, and the adhesive layer 203 can be appropriately adapted from the details described for the adhesive layer 103 of the first embodiment. Furthermore, the positional relationship and various conditions between the adhesive-blocking portion 104 and the rupture line 105 described in the first embodiment can also be selected as the positional relationship and conditions between the non-coated portion 204 and the rupture line 105.

[0079] As explained in the first embodiment, the depth of the break line 105 can be determined to a suitable depth taking into consideration the configuration of the non-adhesive end portion, the positional relationship between the break line 105 and the non-adhesive end portion, etc. For example, as in the second embodiment, when the non-adhesive end portion is formed by a non-coated portion 204 to which no adhesive is applied, (i) when the break line 105 is positioned inside the inner edge of the non-coated portion 204, which is the non-adhesive end portion, in a top view (see FIG. 7), the break line 105 may be kept to a depth that reaches from the print base layer 101 to the pseudo-adhesive layer 102 but does not reach the adhesive layer 203 (see FIG. 7), or may be set to a depth that reaches from the print base layer 101 to the adhesive layer 203 (not shown).

[0080] On the other hand, (ii) when the break line 105 is located within the region of the non-coated portion 204, which is the non-adhesive end, as viewed from above (not shown), the depth of the break line 105 is limited to a depth that reaches from the print substrate layer 101 to the pseudo-adhesive layer 102. In this case, the break line 105 is located outside the inner edge of the non-coated portion 204, which is the non-adhesive end, and is located between the inner edge and the outer edge.

[0081] <Goods>

[0082] FIG. 8 is a partial cross-sectional view of an article to which the information transmission label according to the first embodiment has been affixed.

[0083] The article 3 shown in FIG. 8 is an article 3 in which a information transmission label 10 according to the first embodiment is attached to an adherend 30. The article 3 is an article 3 in which a information transmission label 10 including a printable substrate layer 101, an adhesive layer 103, and a pseudo-adhesive layer 102 disposed between the printable substrate layer 101 and the adhesive layer 103 is attached to the surface of the adherend 30. The adhesive layer 103 has an adhesive-binding portion 104 formed on at least a portion of the edge of the surface opposite the printable substrate layer 101. In a cross-sectional view of the information transmission label 10, a fracture line 105 is formed on the surface of the printable substrate layer 101, the fracture line 105 having a depth that reaches at least the pseudo-adhesive layer 102 from the printable substrate layer 101 so as to enable tearing guidance from the adhesive-binding portion 104 toward the printable substrate layer 101. Needless to say, the information transmission label 20 according to the second embodiment can also be attached to an adherend 30 in a similar manner.

[0084] The information transmission labels 10, 20 according to the present embodiment can be attached to various adherends 30. The adherend 30 may be made of any material as long as the adhesive layer 103 can be attached to it. For example, when the information transmission labels 10, 20 are used as delivery slips, the adherend 30 may be a delivery item or the like. A delivery item typically comprises an item to be delivered and packaging material for packaging the item. Examples of packaging material include wrapping paper, packaging film, packaging boxes, and packaging containers. Examples of packaging material include cardboard, paper, plastic, and metal. Because the information transmission labels 10, 20 are attached to the packaging material of the delivery item, the adhesive layer 103 has an appropriate adhesive strength to the packaging material.

[0085] As described above, the information transmission labels 10 and 20 according to this embodiment allow the printing substrate layer 101 to be easily peeled off and can prevent peeling of the printing substrate layer 101 at unintended locations, and therefore can be suitably used as delivery slips, packaging slips, inventory slips, various work slips, information concealment labels (for example, labels that allow the recipient to peel off the printing substrate layer 101 after receiving it to check the information), tamper-proof labels, personal information protection labels, etc. [Explanation of symbols]
