In addition, the label continuous body 2 may or may not be provided with a display or the like indicating the line to be cut L1.

The activation process is a process of activating the adhesive layer 50 of the label 3 . As shown in FIG. 5 , in this step, light energy (ultraviolet rays, etc.) for activating the adhesive layer 50 is emitted from the energy irradiation unit 120 toward the adhesive layer 50 . This activates the adhesive layer 50 of the label 3 . The label 3 may contain an energy absorbing material that absorbs light energy. An energy absorbing material is preferably added to the adhesive layer 50 and the overcoat layer 40 . In this embodiment, at least one of the adhesive layer 50 and the overcoat layer 40 is added with an ultraviolet absorbing material as an energy absorbing material, and the energy irradiation section 120 irradiates ultraviolet rays. When the adhesive layer 50 is made of a material that is activated by thermal energy, the energy irradiation section 120 applies thermal energy such as hot air to the adhesive layer 50 .

A region of the conveyor 130 on the downstream side of the energy irradiation section 120 is not irradiated with light energy. That is, in the transporting step, the activated label 3A is adhered from the activated position where the adhesive layer 50 is activated (the position irradiated with light energy by the energy irradiation unit 120) to the spaced position spaced apart from the activated position. The layer 50 is transported in an unactivated state. In other words, in the conveying step, the activated label 3A is conveyed from the activated position to the separated position while reducing the adhesive strength of the adhesive layer 50 thereof.

The sticking step is a step of sticking the activation label 3A to the article B at a spaced position away from the energy irradiation unit 120 . Article B is conveyed by a conveyor or the like. When the conveying speed of the conveyor 130 is the first speed, the pasting step is performed within, for example, 15 seconds from the activation step. 5 or more, and when the conveying speed of the conveyor 130 is the second speed, for example, within 5 seconds from the activation step, that is, the adhesive strength of the adhesive layer 50 is a ball in a special ball tack test. No. It may be implemented when it is 6 or more.

As shown in FIGS. 7 and 11, in the printing process, a printing layer 35 is formed on the surface of the upper base sheet 30 by the printing unit 35A. A printing method by the printing unit 35A includes a letter press method, a flexographic method, a gravure method, and the like. In addition, when the upper base sheet 30 printed on at least one of the front surface and the back surface of the upper base sheet 30 in another process is used, the printing process may be omitted.

The cutting step is a step of cutting the upper base material sheet 30 along the contours of the plurality of upper base materials 32 so as to form a plurality of upper base materials 32 arranged at intervals in one direction. As shown in FIGS. 7 and 12 , in the cutting step, the upper base material sheet 30 is cut by the cutting unit 210 along the outline of each upper base material 32 . The cutting unit 210 may have a cutting die having a shape that follows the contour of the upper base material 32 . In the cutting step in this embodiment, the upper base sheet 30 is cut from the surface of the upper base sheet 30 toward the lower base sheet 10 at the position where the bonding layer 20 overlaps the inner anchor portions 64 .

The removing step is a step of removing portions of the upper base sheet 30 other than the plurality of upper base members 32 from the lower base sheet 10 . In the removing step of the present embodiment, as shown in FIGS. 7 and 13, portions of the upper base sheet 30 and the printed layer 35 other than the portions overlapping the respective upper base members 32 in the stacking direction are peeled off. This stripped portion is wound up by a roller.

In the coating step, the overcoat layer 40 is formed on the surface of the lower base sheet 10 and the surfaces of the plurality of upper base materials 32 by supplying a coating material to the surface of the lower base sheet 10 and the surfaces of the plurality of upper base materials 32 . It is a process of forming. As shown in FIG. 7, in the coating process, the coating material is supplied to the surface of the lower base sheet 10 and the surfaces of the plurality of upper base materials 32 by the coating material supply unit 40A. As shown in FIG. 14, in this coating step, the coating material is applied to the surface of the lower base sheet 10 and the surfaces of the plurality of upper base materials 32 so that the lower ends of the intervening portions 46 are located on the inner anchor portions 64 . is supplied. The coating material supply unit 40A forms the overcoat layer 40 by, for example, printing.

As shown in FIG. 7, in the adhesive layer forming step, the adhesive is supplied to the back surface of the lower base sheet 10 by the adhesive supply unit 50A. The adhesive supply unit 50A forms the adhesive layer 50 by, for example, printing.

As described above, in the manufacturing method of the labeled article 5 in the above-described embodiment, the activated label 3A is conveyed to the spaced position away from the activated position, and the affixing process is performed there. By separating the activation device (energy irradiation unit 120) from the device for attaching the activation label 3A to the article, versatility can be enhanced. In other words, the adhesive layer 50 of the label 3 has a relatively long open time after activation. makes it possible to attach the activation label 3A to the article B.

Further, in the label 3 in the above embodiment, the lower base material 12 and the adhesive layer 50 are light transmissive, and the haze value of the non-overlapping region A20 is less than 10.0, so the label 3 is light transmissive. The non-overlapping area A20 is substantially assimilated with the article B, and the overlapping area A10 including the upper substrate 32 is conspicuously visible as the main design portion.

In addition, since the adhesive layer 50 overlaps the overcoat layer 40 in the label material 1 formed by winding the linerless label continuous body 2 in a roll shape, the adhesive layer 50 is It is affected by unevenness caused by the presence or absence of the upper base material 32 . Therefore, there is a problem that the haze value in the non-overlapping area A20 tends to increase. On the other hand, in the label blank 1 of the present embodiment, the haze value of the non-overlapping area A20 is less than 10.0, so the overlapping area A10 including the upper substrate 32 is conspicuously visible as the main design portion. .

The outer region A21 is a region that overlaps with the lower base material covering portion 42 in the stacking direction. The inner region A22 is a region that does not overlap the lower base material covering portion 42 in the stacking direction. The inner area A22 is formed inside the outer area A21 and around the overlapping area A10 in plan view of the label 3 . The haze value of the inner area A22 is smaller than the haze value of the outer area A21. In this aspect, since the outline of each upper base material 32 becomes clearer, each upper base material 32 is conspicuously visible as a display portion. Furthermore, since the gap is formed between the lower base material covering portion 42 and each upper base material 32, the outline of each upper base material 32 becomes clear, so that each upper base material 32 is more conspicuously visible. be.

Moreover, in the above embodiment, the overcoat layer 40 and the anchor coat layer 60 may be omitted. In this case, the non-overlapping area A20 is composed of the lower substrate 12 and the adhesive layer 50, and has a haze value of less than 7.0.
