Description

  The present invention relates to an adhesive label.

  2. Description of the Related Art Conventionally, in the field of meat products such as sliced ham, a technique for distributing a plurality of packaged bodies (units) that package the foods in a connected state (a connected body) has been widely used. If it demonstrates in detail, the connection body will be formed by connecting the several package in the state shifted and arranged in one direction so that it may overlap partially by an adhesive label. The said adhesive label is a label extended in the shifting direction of a some package, and is each affixed on each package with the adhesive layer formed in the back surface. When a consumer purchases the above-described unit of the linked body and consumes the food, the consumer removes the adhesive label and separates one of the packaged bodies from the linked body (see, for example, Patent Document 1).

By the way, as a structure of an above-mentioned adhesive label, the structure which laminated | stacked the adhesive layer on the label back surface side of the base material layer which consists of paper conventionally is known. In addition, since the above-mentioned connected body is often refrigerated, the surface of the base material layer is coated with a water-repellent coating agent such as varnish so that the base material layer does not deteriorate due to water drops or the like. In many cases, a film layer is laminated on the surface via an adhesive layer. The film layer described above is made of a sheet having excellent water resistance made of a synthetic resin such as polypropylene resin (hereinafter referred to as PP resin).

  However, in the above-described conventional pressure-sensitive adhesive label, when the pressure-sensitive adhesive label attached to the package is peeled off, the base material layer made of paper may be peeled off and torn. There is a problem that a part of the material layer remains and the adhesive label cannot be peeled off. Therefore, in the manufacturing process of connecting a plurality of packaging bodies with adhesive labels, when there is a deviation in the position or orientation of the adhesive labels, it is necessary to reattach the adhesive labels. It is complicated. In addition, it is necessary to separate and dispose of the package and the adhesive label after the product is consumed, but it is complicated to cleanly separate the package and the adhesive label.

  The present invention has been made in consideration of the above-described conventional problems, and an object of the present invention is to provide an adhesive label that can be peeled cleanly even after being pasted.

  The pressure-sensitive adhesive label according to the present invention is a pressure-sensitive adhesive label comprising at least a base material layer made of paper and a pressure-sensitive adhesive layer provided on the label back surface side of the base material layer, the label back surface side of the base material layer Further, a resin film layer is laminated through an adhesive layer having adhesiveness stronger than that of the adhesive layer, and the adhesive layer is laminated on the label back side of the film layer.

  Due to such features, when the adhesive label is once attached and then peeled off, the resin film layer is not easily torn.

  In the pressure-sensitive adhesive label according to the present invention, the film layer is preferably made of an easily tearable film.

Thereby, the adhesive label can be easily cut by hand from any direction without using a blade or the like. In addition, since the easily tearable film layer is reinforced by the adhesive layer, it is difficult to tear when the adhesive label is peeled off.
The term “easy tear film” as used herein refers to a resin film having a tearability that allows tearing by hand, and has an end tear resistance of 45 N or less when bonded to paper. Say film.

  In the pressure-sensitive adhesive label according to the present invention, a part of the adhesive layer on the back side of the label is formed with a paste-killing portion that has been subjected to a paste-killing process that reduces the adhesive strength of the pressure-sensitive adhesive layer. It is preferable that a printing part is formed on the back side of the label.

Thereby, in the state where the said adhesive label was stuck, it will be in the state which cannot see a printing part, and will be in the state which can see a printing part by rolling an adhesive label.
In addition, as described above, when the film layer has easy tearability, it is possible to scratch the part where the paste-killing part is formed while breaking the adhesive label, so by checking whether the adhesive label is broken or not, It can be determined whether or not the adhesive label has been burned.

  In the pressure-sensitive adhesive label according to the present invention, it is preferable that the printing unit has at least a code including information.

  As a result, it is possible to obtain information by reading the code with a dedicated reading machine over the adhesive label.

  In addition, the adhesive label according to the present invention has a curled portion that can be partially curled while cutting along a ruled line that is easy to cut, and the paste-killing portion is formed on the label back side of the curled portion. It is preferable that

  Thereby, even if it does not squeeze the whole adhesive label, it will be in the state which can see a printing part by only squeezing the turning part. At this time, the curled portion is scooped while breaking along the ruled line, so that the curled portion can be scooped cleanly. Further, since the paste-killing portion is formed on the back side of the label of the punched portion, once the punched portion is punched, the scraped portion is difficult to re-stick and remains in the state where the punched portion remains punched.

  According to the pressure-sensitive adhesive label according to the present invention, when the pressure-sensitive adhesive label is once attached and then peeled off, the resin film layer is not easily broken, so that the pressure-sensitive adhesive label can be peeled cleanly. Therefore, it becomes easy to reattach the adhesive label, and the adhesive label and the pasting object such as a package can be separated cleanly.

Hereinafter, an embodiment of an adhesive label according to the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of a connecting body 1 connected by an adhesive label 5 which is an example of the present invention. 2 is a cross-sectional view of the connecting body 1 described above, (a) is an overall cross-sectional view taken along line A-A shown in FIG. 1, and (b) is an enlarged cross-sectional view of a portion P shown in FIG. 2 (a). It is.

  As shown in FIGS. 1 and 2, the connecting body 1 has a configuration in which a plurality (three in FIGS. 1 and 2) of packaging bodies 2 are connected. The package 2 is a member that packages and seals food such as sliced ham, and the food X is disposed at the center of the surface of the rectangular substrate 3 and the film-shaped covering sheet 4 is coated thereon, and the food X The substrate 3 and the covering sheet 4 are bonded around the periphery of the substrate. The food X in the package 2 is sealed by the substrate 3 and the covering sheet 4 described above. Further, the plurality of packaging bodies 2 are arranged so as to be slightly shifted in one direction (left-right direction in FIG. 1) so as to partially overlap.

  On the surface of the connector 1 (upper side in FIG. 2), a first packaging body connection adhesive label (adhesive label of the present invention, on which a product name, a catchphrase, and the like are printed) is simply referred to as “adhesive label 5”. ) And the second adhesive label 6 for connecting the packaged body on which the food name such as the name of the raw material and the content and the barcode is printed on the back surface (lower side in FIG. 2) of the coupled body 1 Is pasted. These adhesive labels 5 and 6 are strip-like labels that are long in one direction (a direction in which a plurality of packaging bodies 2 are shifted and arranged) and extend between the packaging bodies 2 and 2 disposed at both ends. It is stuck on each package 2. These adhesive labels 5 and 6 are connected to a plurality of packages 2.

Here, the detailed configuration of the pressure-sensitive adhesive label 5 on the surface side of the connecting body 1 will be described.
FIG. 3 is a schematic diagram schematically showing the cross-sectional structure of the pressure-sensitive adhesive label 5, and is a schematic cross-sectional view between BB shown in FIG. 1. FIG. 4 is a schematic cross-sectional structure of a film layer 14 described later. FIG. 5 is a schematic diagram schematically showing a cross-sectional structure of the pressure-sensitive adhesive label 5, and is a schematic cross-sectional view between CC shown in FIG. 1. FIG. It is a top view of the adhesive label 5 showing the state which wrinkled.

  As shown in FIG. 3, the pressure-sensitive adhesive label 5 has a protective layer 10, a printing layer 11, a base material layer 12, and a layer in order from the label surface side (upper side in FIG. 3, hereinafter simply referred to as “surface side”). The adhesive layer 13, the film layer 14, and the adhesive layer 15 are laminated. That is, the film layer 14 is laminated on the back side of the label of the base material layer 12 (the lower side in FIG. 3, hereinafter simply referred to as “back side”) via the adhesive layer 13. An adhesive layer 15 is laminated. Further, the printing layer 11 is laminated on the surface side of the base material layer 12, and the protective layer 10 is laminated on the surface side of the printing layer 11.

  The base material layer 12 is made of paper made of wood or non-wood plant, and for example, coated paper such as gloss coated paper is used. In addition, as the base material layer 12, another kind of paper quality layer may be sufficient, for example, non-coating paper may be sufficient. Moreover, the paper of the base material layer 12 may not be paper made from wood or non-wood plants, but may be synthetic paper containing PP resin, for example.

  The film layer 14 is a layer made of a resin, and is made of a synthetic resin sheet such as polyethylene terephthalate (PET). The film layer 14 has substantially the same shape as the base material layer 12 and is bonded to the entire back surface of the base material layer 12. The film layer 14 is made of an easily tearable film that can be easily broken by hand. Specifically, as shown in FIG. 4, the easily tearable film forming the film layer 14 has a sandwich structure in which both sides of the amorphous polymer layer 14a are covered with the crystalline polymer layer 14b, and in which direction Therefore, it has a hand cutting property without directivity that can be easily cut by hand. The amorphous polymer layer 14a is a fragile layer in which it is difficult to maintain a thin film shape alone. The crystalline polymer layer 14b is a protective layer for maintaining the shape of the amorphous polymer layer 14a, and is a thin film layer thinner than the amorphous polymer layer 14a. For example, when the film layer 14 having a thickness of 14 μm is formed, both sides of the amorphous polymer layer 14 a having a thickness of 10 μm are respectively covered with the amorphous polymer layer 14 b having a thickness of 2 μm. Further, the above-described crystalline polymer layer 14b is bonded to the surface of the amorphous polymer layer 14a by heat treatment or the like.

  The adhesive layer 13 is a layer for adhering the base material layer 12 and the film layer 14 described above, and is made of an adhesive for dry lamination (such as a solvent-based adhesive or a reactive adhesive). The adhesive layer 13 is formed with a uniform thickness between the base material layer 12 and the film layer 14. The adhesive layer 13 is formed of an adhesive that exhibits at least an adhesive force stronger than that of the pressure-sensitive adhesive layer 15.

The pressure-sensitive adhesive layer 15 is a layer for sticking the pressure-sensitive adhesive label 5 to the package 2 of the adherend, and is made of, for example, an emulsion-based pressure-sensitive adhesive. As the adhesive layer 15, a known adhesive such as natural rubber, synthetic rubber, acrylic, or silicone can be used. For example, polyethylene resin or acrylic resin can be used. The adhesive layer 52 is formed on the entire back surface of the film layer 14 with a uniform thickness.
In addition, in the state before sticking the adhesive label 5 to the package 2, a separator 16 made of, for example, glassine paper is attached to the back side of the adhesive layer 15.

  The printing layer 11 is an ink layer on which a product name, a catchphrase, and the like are printed, and is printed by letterpress printing. In addition, as a printing method of the printing layer 11, a well-known printing method can be used, for example, the printing layer 11 can also be formed by screen printing, gravure printing, offset printing, inkjet printing, etc.

  The protective layer 10 is a layer for imparting water resistance to the surface of the pressure-sensitive adhesive label 5 and protecting the printed layer 11 from scratches. For example, a coating agent having water repellency is applied to the surface of the printed layer 11. It is formed by laminating a film excellent in water resistance on the surface of the printing layer 11. As the above-mentioned coating agent, for example, varnish can be used, and as the above-mentioned film, for example, a PET film having the same tearability as that of the film layer 14 can be used.

  Moreover, as shown in FIG. 1, the adhesive label 5 is formed with a turn portion 50 that can be partially wound while being cut along a ruled line 51 that is easy to cut. If it demonstrates in detail, the turn part 50 is arrange | positioned inside the outer edge of the adhesive label 5, and is formed in the right side in FIG. 1 in this Embodiment. The bent portion 50 is partitioned by a ruled line 51, and a part of the outer edge thereof is integrally connected to a label main body 52 (a portion other than the bent portion 50 of the adhesive label 5). More specifically, the turn part 50 has a substantially rectangular shape defined by a substantially U-shaped ruled line 51, and one side (the lower side in FIG. 1) of the turn part 50 is connected to the label main body 52. ing. The ruled line 51 may be a through or non-penetrated cut line formed continuously along the outer edge of the turn part 50, or a part of the ruled line 51 may be a cut line and the remaining part may be perforated. It may be.

  As shown in FIGS. 5 and 6, the paste-killing portion 17 that has been subjected to paste-killing processing that reduces the adhesive strength of the adhesive layer 15 is formed on the back surface side of the above-described wound portion 50. The paste-killing portion 17 is formed by applying a varnish or printing ink on the back surface side of the adhesive layer 15 or the front surface side of the separator 16, and has a uniform thickness over the entire curling portion 50. Is formed.

  A printing unit 18 is formed on the back side of the paste killing unit 17 described above. In the printing unit 18, a code including information is formed. This code is a code that allows information to be read by a dedicated reading machine. For example, there are a two-dimensional code such as a QR code (registered trademark) and a one-dimensional code such as a barcode. Note that characters or symbols may be formed in the printing unit 18 in addition to the above-described code or instead of the above-described code. Moreover, when forming the common printing part 18 in the some adhesive label 5, it is preferable to form the printing part 18 by printing systems, such as letterpress printing, screen printing, gravure printing, and offset printing, and on the contrary In the case where different print portions 18 are formed in the adhesive label 5, it is preferable to form the print portions 18 by ink jet printing.

  According to the pressure-sensitive adhesive label 5 having the above-described configuration, the resin film layer 14 does not cause delamination, and the easily tearable film layer 14 is reinforced by the adhesive layer 13. When the pressure-sensitive adhesive label 5 attached to the package 2 is peeled off, the film layer 14 is hardly broken. Therefore, the pressure-sensitive adhesive label 5 can be peeled cleanly, and the work of re-sticking the pressure-sensitive adhesive label 5 and the work of separating the pressure-sensitive adhesive label 5 and the package 2 can be easily performed.

  Moreover, since the film layer 14 has easy tearability, the adhesive label 5 can be easily cut by hand from any direction without using a blade or the like. Therefore, the packaging body 2 can be easily separated from the connection body 1 by tearing the adhesive label 5 attached to the connection body 1 by hand or the like.

  Further, by turning the curling unit 50, the printing unit 18 printed on the back surface of the curling unit 50 can be seen, the code of the printing unit 18 can be read, and the information contained in the code of the printing unit 18 can be read. Obtainable. On the other hand, if the turning section 50 is not turned, the printing section 18 cannot be seen and the code of the printing section 18 cannot be read. Therefore, it is possible to construct a mechanism in which only the consumer who has purchased the product can acquire the information of the printing unit 18. For example, by including the access key information of a predetermined site in the code of the printing unit 18, it is possible to construct a mechanism in which only the consumer who has purchased the product can access the site.

  Further, when turning the turning portion 50, the turning portion 50 is turned along the ruled line, so that the turning portion 50 can be turned cleanly. Thereby, when turning the turning part 50, it can prevent that the turning part 50 fractures | ruptures, and the printing part 18 formed in the back surface of the turning part 50 can be read reliably.

  Moreover, since the paste-killing part 17 is formed in the back surface of the turning part 50, once the turning part 50 is beaten, it is difficult to make it stick again, and the turning part 50 will be in the state still beaten. . For this reason, it can be judged by checking the sticking state of the turn part 50 whether the turn part 50 was beaten. Accordingly, unauthorized reading of the printing unit 18 can be prevented.

As mentioned above, although embodiment of the adhesive label which concerns on this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the above-described embodiment, the adhesive label 5 for connecting a plurality of packaging bodies 2 is described. However, the present invention is not limited to such an adhesive label 5 for connection. The adhesive label may be affixed to a single product.

  In the embodiment described above, the printing layer 11 and the protective layer 10 are laminated on the surface side of the base material layer 12. However, in the present invention, the configuration of the surface side of the base material layer 12 can be changed as appropriate. For example, the resin layer which consists of PET etc. may be laminated | stacked on the surface side of the base material layer 12, and the structure by which the printing layer was formed in the surface side of this resin layer may be sufficient.

  Further, in the above-described embodiment, the curled portion 50 defined by the substantially U-shaped ruled line 51 is formed inside the outer edge of the adhesive label 5, but the curled portion in the present invention is the position and shape described above. It is not limited to. For example, as shown in FIG. 7 (a), it may be a twisted portion 150 defined by a pair of parallel lines 151 extending from the outer edge of the adhesive label 5, or in FIG. 7 (b). As shown in the figure, a twisted portion 250 that is partitioned by a single ruled line 251 extending from the outer edge of the pressure-sensitive adhesive label 5 and disposed at the end of the pressure-sensitive adhesive label 5 may be used.

  In the above-described embodiment, the curled portion 50 is formed on the adhesive label 5, and the paste-killing portion 17 and the printing portion 18 are formed on the back side of the curled portion 50. Alternatively, the configuration may be such that the glue part 50 and the printing part 18 are formed on the back side of the pressure-sensitive adhesive label without forming the turning part 50. For example, the structure which can read the printing part 18 by forming the paste-killing part 17 and the printing part 18 in the back surface side of the edge part of the adhesive label 5, and rolling the edge part of the adhesive label 5 may be sufficient. Furthermore, the present invention can be configured such that the paste killing part 17 and the printing part 18 are omitted.

  In the above-described embodiment, the film layer 14 is composed of a three-layer easily tearable film in which the crystalline polymer 14b is coated on both sides of the amorphous polymer 14a. It is also possible to form the film layer 14 with a film. For example, an easily tearable film having a structure in which a plurality of fine holes are formed on the entire surface can be used. Furthermore, this invention can also use the film layer which does not have easy tearability. For example, as described above, in the case of the pressure-sensitive adhesive label 5 attached to a single product, or in the case of a configuration in which the printing unit 18 is read by rolling the end portion of the pressure-sensitive adhesive label 5, In the case of a configuration that does not include the printing unit 18, a film layer that does not have easy tearability can be used.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the gist of the present invention, and the above-described modified examples may be appropriately combined.
