In the method for producing a releasable label of the present invention, the opaque layer printed on both sides is adhered to one side of the transparent layer by the adhesive layer, and the releasable releasable adhesion layer is provided on the other side of the transparent layer. Method of producing a re-peelable label,

Can provide a releasable label that is easier to peel than before.

Further, the adhesive layer is made of a UV curing adhesive, and after the adhesive layer forming step,
By having a UV irradiation step of curing the adhesive layer by UV irradiation, the adhesive layer made of this UV curing adhesive is disposed at the central position in the thickness direction of the label, so it is likely to be peeled off. The opaque layer on the top layer is connected to the outside through the UV curing adhesive layer to the transparent layer directly attached to the adherend such as can container only when lateral force is applied to the label. Because of this, the transparent layer and the releasable adhesion layer can be easily peeled off from the adherend.

  Here, curing of the adhesive layer in the UV irradiation step is performed by UV irradiation before bonding, anti-curing and bonding, or after the formed adhesive layer is sandwiched, UV irradiation is performed from the transparent layer side. It can include those that are cured to a bondable state.

Furthermore, when the UV curing adhesive layer is formed in a relatively soft state, when the lateral force acts on the re-peelable label, the opaque layer is easily deformed in the in-plane direction with respect to the transparent layer. The upper laminate can be easily peeled off from the adherend from the releasable adhesion layer.
Alternatively, when the UV curing adhesive layer is formed in a relatively hard state, when the lateral force is applied to the re-peelable label, it deforms in the in-plane direction of the label with the opaque layer and the transparent layer integrated. Since it becomes easy to make it possible, it becomes possible to peel easily the layered product above a re-peeling adhesion layer from a covering object.

  In addition, when the adhesive layer is made of a transparent adhesive and the releasable adhesive layer is made a transparent layer, information printed on the back surface of the opaque layer can be viewed through the adhesive layer.

In the present invention, there is provided an adhesive-killing step of forming an adhesive-killed layer between the re-peeling adhesive layer and the backing sheet after the peeling step.
In the paste-killing step, the paste-sticky layer is formed only partially with respect to the label contour, thereby weakening the adhesion between the releasable sticking layer and the backing in the paste-killed area where the paste-killed layer is formed. And forming a trigger portion that enables the upper laminate to be easily peeled from the adherend from the releasable adhesion layer, and a glued killing region of a part where the glued killing layer is formed, From the contour position of the re-peeling label provided with the paste killing area, it becomes possible to make the label easy to be turned off as a trigger for peeling the whole of the deposition area.

  Here, if the glue killing area in which the glue killing layer is formed is provided at an inner position corresponding to a part of the label outline, the glue killing area is not in contact with the label outline, and the label outline has a minute length It can be formed as an inner state, and during transport, it is firmly attached to the surface of a can container or the like so as not to be peeled in an unintended state during transportation, and is peeled again. In this case, the adhesive-killing area immediately inside the label contour allows the purchaser of the can container to easily peel off.

  Alternatively, the glue killing area in which the glue killing layer is formed can have a part where the glue killing area contacts the label outline and a part that does not touch if the glue killing area is provided at an inner position corresponding to a part of the label outline Preferably, a paste killing area is formed as a position touching a part of the label outline, and only a portion near the center of a part of the touching label outline touching the paste killing area partially enters the inside of a minute length from the label outline It is possible to form it as a entangled state, and by attaching only this portion to the surface of the can container etc., the re-peeling label is not intended to be peeled off during transport on the surface of the can container etc. When maintaining the firmly attached state and performing re-peeling, it is possible that the purchaser of the can container or the like can easily peel off because there is another glue killing area in contact with the label contour. That.

Further, in the present invention, in the paste killing step,
In order to peel off a part of the glue-killed region from the part of the label contour on which the glue-killed layer is formed, by adopting a means in which the glue-killed layer is formed in contact with a predetermined part of the label contour. It is also possible to make the label easy to flip as a trigger for

In the removable label of the present invention, the removable label produced by any of the above-mentioned production methods,
When the opaque layer printed on both sides, the adhesive layer, the transparent layer, and the releasable adhesion layer are laminated, thereby adhering to the adherend by the releasable adhesion layer While being able to visually recognize only the information on the outer surface which is the front side of the opaque layer, it can be easily peeled off from the adherend from the lower position of the releasable adhesive layer thereafter. After peeling, the information printed on the back of the opaque layer can be viewed through the adhesive layer and the releasable adhesive layer.

  Moreover, since the said backing sheet is made into a long and the several re-peeling label is spaced apart and stuck in the direction to which it extends, it becomes easy to utilize for the mechanical sticking using a labeler, for example.

Moreover, it is the re-peeling label manufactured by the manufacturing method as described in any one of the above,
An adherend is formed by laminating the releasable adhesion layer by laminating the opaque layer printed on both sides, the adhesive layer, the transparent layer, the releasable adhesion layer, and the glue killing layer. When pasting on a surface, only the information on the outer surface, which is the front side of the opaque layer, is visible, and then, when it is peeled from the adherend from the lower position of the releasable adhesion layer, And the information printed on the back surface of the opaque layer can be viewed through the paste layer, the adhesive layer and the releasable adhesive layer after the layer is peeled off.

In addition, the backing sheet is made long, and a plurality of releasable labels are separated and attached in the extending direction.
In the case of sticking on, for example, a circumferential can container side surface, by forming the glue killing layer in the same position in plan view with a plurality of releasable labels in the extending direction of the mount. By repositioning the direction from the label center position toward the paste killing area where the paste killing layer is formed in the same direction as the cylindrical axis direction, along the circumferential can container side surface again Since the peeling label is attached in a curved state, it is possible to prevent careless peeling from the paste killing area during transportation or the like.

  Here, “the adhesively killed layer is formed in the same position in a plan view with a plurality of releasable labels in the direction in which the backing sheet extends” means that a plurality of temporary attachment is made to the backing sheet In the re-peelable label, it means that the direction in which the glue-killed region where the glue-killed layer is formed is disposed from the center position of each re-peelable label is in the same direction. That is, "the adhesive layer of each releasable label is formed on the same side with respect to the extending direction of the backing sheet".

  In addition, the longitudinal direction from the center of the label to the position where the adhesive layer is formed in the label outline is formed in the same vertical position as the direction in which the backing sheet extends. On the opposite side of the backing sheet or releasable sticking layer so as to have the same distance as the separation distance of the label when peeling off the backing sheet and at least the long releasable sticking layer to form the paste killing layer The adhesive layer is separated, formed, re-adhered, and then a long laminate including the opaque layer, the adhesive layer, the transparent layer, the re-peeling layer and the adhesive layer is punched into the label outline. Thus, in a plurality of re-peelable labels, it is possible to produce the adhesive-killed layer as the same longitudinal position all and form a state of being intermittently attached to a long backing sheet.

  Here, the longitudinal position refers to the extending direction of the long backing sheet and the direction from the central position of the plurality of releasable labels intermittently attached thereto toward the formed glue killing area of the glue killing layer And means all aligned as the same direction.

  In addition, the direction from the center of the label to the position where the adhesive layer is formed in the label outline is formed in a lateral position substantially orthogonal to the extending direction of the backing sheet in plan view. When peeling off the backing sheet and at least the long releasable adhesion layer to form the paste-killing layer, the paste on the opposite surface of the backing sheet or releasable adhesion layer has the same distance as the separation distance of the label. Alternatively, after arranging the killing layer separately or continuously forming the glue killing layer in the extending direction of the backing continuously only for the portion forming the glue killing layer as the predetermined width dimension and re-attaching In a plurality of releasable labels, by punching out a long laminate in which an opaque layer, an adhesive layer, a transparent layer, a releasable adhesion layer, and an adhesive killing layer are laminated into a label outline, and cutting out contours and scraps. , All in the same vertical position Intermittently forming a glue killing layer can be produced as a state in which adhered to the mount of the elongated.

A printed front printing layer 17 and a printed back printing layer 15 are provided on both sides of the opaque layer 16.

  The opaque layer 16 may be made of resin, paper, synthetic paper, Yupo (Yupo Corporation registered trademark), which is a film method synthetic paper mainly made of polypropylene as an example. The thickness of the opaque layer 16 can be set to, for example, about 30 μm to 100 μm, more preferably about 50 μm to 80 μm, or about 60 μm.

  The front printing layer 17 and the back printing layer 15 are printed on the opaque layer 16, the front printing layer 17 represents information etc. of the application for the campaign etc., and the back printing layer 15 has the lottery number or the application It is considered as concealed information such as application information such as barcodes and URLs to be used. The display information shown by the back printing layer 15 can not be visually recognized unless the re-peeling label 10 is peeled from the can container or the like.

  The front printing layer 17 and the back printing layer 15 can have a freedom in the selection of the ink by the adhesive layer 14 being a UV radiation curing adhesive as described later. Bleeding can be prevented from occurring in printing. Moreover, since the front printing layer 17 and the back printing layer 15 are printed on the same opaque layer 16, problems such as displacement of the front printing layer 17 and the back printing layer 15 may occur at the time of bonding. Absent. Furthermore, as compared with the case of printing on the transparent layer 13, the printing on the back printing layer 15 can be improved and clear printing can be performed.

In addition, the plurality of re-peeling labels 10 are attached to the backing sheet 18 in the same direction, so that the mechanical application can be performed easily and continuously.

  Furthermore, the purchaser of the can container (adherend) etc. re-peels the re-peeling label 10 from the can container surface with a finger or a nail, etc., whereby the visual information such as the campaign contents printed as the back printing layer 15 It is made visible.

  According to the re-peelable label in this embodiment and the method for manufacturing the same, when it is attempted to re-peel the surface of the can container to which the re-peelable label 10 is attached with a finger or a nail, the paste killing layer 11, the re-peelable layer As shown by arrow A in FIG. 1 with respect to the releasable label 10 which is a laminate in which the transparent layer 13, the adhesive layer 14, the back printing layer 15, the opaque layer 16 and the front printing layer 17 are sequentially laminated. A force is applied in the lateral direction (in-plane direction) in order to separate.

  At that time, the glue-killing area in which the glue-killing layer 11 is formed triggers the re-peelable label 10 to be peeled again. At this time, the opaque layer 16 side at the upper position of the releasable label 10 is adhered to the surface of the can container by the releasable adhesive layer 12 against the lateral force indicated by the arrow A in the figure. A force is applied to the transparent layer 13 in the lateral direction. As a result, lateral stress is generated in the adhesive layer 14 between the transparent layer 13 and the opaque layer 16.

  Since the adhesive layer 14 used as the UV curing adhesive has a set range of hardness, according to the hardness, the thickness and hardness (strength) of the transparent layer 13 and the opaque layer 16 are as follows: It will act.

  First, when the hardness of the adhesive layer 14 is set relatively high (hard), the lateral peeling force acting on the opaque layer 16 can be easily transmitted to the transparent layer 13. The transparent layer 13 easily follows the deformation in the peeling direction of the opaque layer 16 lifted from the surface of the can container, triggered by the adhesive killing area in which the adhesive killing layer 11 is formed, whereby the adhesive killing layer 11 is formed. The re-peeling adhesive layer 12 sequentially separates from the surface of the can container from the glue killing area, and the re-peeling label 10 is re-peeled.

  On the other hand, in the case where the hardness of the adhesive layer 14 is set to be relatively low (soft), the adhesive layer 14 tries to deform laterally in response to the lateral peeling force applied to the opaque layer 16. The laminate of the releasable label 10 is deformed such that the opaque layer 16 and the transparent layer 13 are displaced in the lateral direction along each other. In this state, since the adhesive layer 14 has sufficient adhesive strength, the transparent layer 13 is pulled close to the laterally shifted opaque layer 16 to form the glue-killing layer 11. The transparent layer 13 easily follows the deformation in the peeling direction of the opaque layer 16 lifted from the surface of the can container triggered by the area, and the releasable adhesion layer from the adhesive killing area where the adhesive killing layer 11 is formed. The re-peelable label 10 is re-peelable as 12 sequentially separates from the can container surface.

  Furthermore, the re-peeling label 10 is manufactured as a once-peeled-off state in which the re-peeling adhesion layer 12 and the backing sheet 18 are peeled off in the peeling step S06 and re-sticked in the re-sticking step S08. The re-peeling adhesive layer 12 is sequentially removed from the can container surface in re-peeling by the purchaser in order to purchase the re-peeling label 10 in a state of being attached to the can container surface after peeling off the backing sheet 18. It can be urged to be easily separated, which allows the purchaser of the removable label 10 to easily remove it.

  In addition, as described above, it is possible to urge the re-peeling adhesion layer 12 to be easily separated from the can container surface one after another, triggered by the glue-killed region where the glue-killing layer 11 is formed. The re-peeling of the re-peeling label 10 can be easily performed.

  According to the re-peeling label 10 in the present embodiment, since it is possible to easily re-strip in this way, even old people, children, women, or purchasers with weak finger power can be easily It becomes possible to re-peel and to visually recognize confidential information (hiding information) of back printing layer 15.

In the re-peelable label 10 according to this embodiment, as shown in FIG. 6, a projecting portion that protrudes toward the outer side of the contour is provided as a contour shape of the re-peelable label 10. The glue killing layer 11 can be provided to facilitate re-peeling.
In this case, since the protruding portion can be easily peeled again, the paste killing layer 11 can be not provided other than the protruding portion of the releasable label 10.

  Alternatively, in the releasable label 10 according to this embodiment, as shown in FIG. 7, the glue killing layer 11 corresponds to, for example, a lateral position with respect to the contour shape of the releasable label 10 set in the punching step S14. It can be provided in a separated state.

Here, as shown in FIG. 7, in the re-peeling label 10 which is intermittently attached to a plurality of sheets intermittently in the extending direction of the backing sheet 18, as shown in FIG. The lateral direction is set such that the direction in which the killing layer 11 is disposed is substantially orthogonal to the direction in which the backing sheet 18 extends.
In this case, in the paste-killing step S07, it is possible to form the paste-killing agent by application, printing or the like as a predetermined width continuous in the extending direction of the backing sheet 18 corresponding to the area to be the paste-killed layer 11. is there. In this case, it is not necessary to position the label outline and the glue killing area in the longitudinal direction (the direction in which the backing sheet 18 extends) as compared to the case where the glue killing area forming the glue killing layer 11 is formed intermittently. Therefore, it is possible to save time for adjustment.

It is irradiated. The UV irradiation part 212 is irradiated so that the UV (ultraviolet light) transmitted through the transparent layer 13 is cured so that the adhesive layer 14 to be a UV curing adhesive has sufficient strength. Conditions are set.

  As shown in FIG. 9, in the paste killing step S07 shown in FIG. 8, the paste killing layer 11 is partially formed by the paste killing printing unit 207 on the surface of the backing sheet 18 on the side of the releasable sticking layer 12 exposed in the peeling step S06. Form. In addition, although the glue killing layer 11 may be formed on the surface of the releasable adhesion layer 12 exposed to the side of the mount 18, in the present embodiment, it is formed on the side of the mount 18. The formation of the paste killing layer 11 can be appropriately selected depending on the material, composition, etc. of the paste killing layer 11 such as printing, coating, spraying and the like.

Hereinafter, a third embodiment of a releasable label and a method of manufacturing the same according to the present invention will be described based on the drawings.
FIG. 10 is a schematic cross-sectional view showing the removable label in the present embodiment, FIG. 11 is a plan view showing the surface of the removable label in the present embodiment, and FIG. 12 is the surface of the removable label in the present embodiment This embodiment is different from the first and second embodiments described above in the present embodiment in terms of the arrangement of the paste killing layer, and other than the first and second embodiments described above. The same reference numerals are given to the configuration corresponding to the embodiment and the description thereof will be omitted.

  In the re-peeling label 10 in the present embodiment, as shown in FIG. 10, the glue killing layer 11 is not in contact with the label contour, and is located inside thereof.

  In the present embodiment, as shown in FIG. 11, the glue killing area in which the glue killing layer 11 is formed is provided at an inner position corresponding to a part of the re-peelable label 10 contour, but it becomes a glue killing area. The contour on which the paste killing layer 11 is formed is not in direct contact with the contour of the re-peelable label 10, and is formed as being inward from the re-peelable label 10 by a minute length.

  Thereby, the releasable label 10 in the present embodiment is covered with the releasable adhesion layer 12 without the glue killing layer 11 at a position outside the contour where the glue killing layer 11 is formed in the vicinity of the releasable label 10 contour. In a state of being directly stuck to a can container or the like which is an adherend, the paste killing layer 11 is present in a predetermined area immediately inside.

  As a result, when the re-peeling label 10 is re-peeled while maintaining the state of firmly adhering to the surface of the can container or the like so that the re-peeling label 10 is not unintentionally peeled off during transportation. The area of the thin releasable adhesion layer 12 with the glue killing layer 11 formed immediately inside the releasable label 10 contour enables the purchaser of the can container to easily separate.

  Furthermore, in the present embodiment, as shown in FIG. 12, the paste killing area in which the paste killing layer 11 is formed can have a part in contact with the re-peeling label 10 contour and a part not in contact with it. While the region of the glue killing layer 11 is formed as a position in contact with a portion of the re-peelable label 10 contour, only a portion near the center of a portion of the label contour in contact with the region where the glue killing layer 11 is formed It is formed in such a manner that the releasable label 10 is formed into a minute length inside from the contour of the releasable label 10, and the releasable adhering layer 12 of this portion is directly adhered to the can container etc without the paste killing layer 11 it can.

  In this case, the outline in which the paste killing layer 11 is formed by the point-like releasable adhering layer 12 in which the outline of the paste killing layer 11 is only a portion entering the minute length inner side from the outline of the stripping label 10 By being attached to the surface of the can container or the like at a further outside position, the releasable label 10 is kept firmly adhered to the surface of the can container or the like during transportation so as not to be peeled off in an unintended state during transport. At the same time, when re-peeling is performed, there is a region where another paste killing layer 11 is formed in contact with the re-peeling label 10 contour, which allows the purchaser of the can container or the like to easily peel off. .

  In this embodiment, in the vicinity of the releasable label 10 contour, a micro area where the releasable adhesion layer 12 is adhered to the can container is formed at a position outside the contour where the glue killing layer 11 is formed. Thus, even if the area of the glue killing layer 11 is reduced as compared with the first and second embodiments, the same easy peelability can be maintained. Here, to make the area of the glue killing layer 11 itself small means that the area length of the glue killing layer 11 in the direction from the vicinity of the outline of the re-peelable label 10 toward the center of the label can be shortened. In other words, it means that the area length of the paste killing layer 11 in the radial direction of the releasable label 10 can be shortened.

  Furthermore, in the present embodiment, it is possible to make the region of the glue killing layer 11 a shape other than the above. For example, it is also possible to provide a plurality of areas of the point-like releasable adhesion layer 12 without the paste killing layer 11 spaced apart.
