<Laminated body for wristband production>
One embodiment of the wristband production laminate (hereinafter abbreviated as “laminate”) of the present invention will be described.
In FIG. 1, the laminated body of this embodiment is shown. The laminate 1 of this embodiment includes an intermediate base material 10, anchor layers (front-side anchor layer 20a and back-side anchor layer 20b) provided on both surfaces of the intermediate base material 10, and the intermediate base material 10 of the front-side anchor layer 20a. The ethylene-based resin layer 30 provided on the opposite surface, the surface base material 40 provided on the surface of the ethylene-based resin layer 30 opposite to the front anchor layer 20a, and the intermediate substrate 10 of the back-side anchor layer 20b. And a barrier layer 50 provided on the opposite surface.
In the present embodiment, the exposed surface 50a of the barrier layer 50 is an embossed surface.

(Intermediate base material)
The intermediate substrate 10 is preferably a layer having flexibility and toughness in order to give the laminate 1 flexibility and toughness.
As the intermediate substrate 10, for example, a sheet made of unstretched polyethylene terephthalate, unstretched polypropylene sheet, polyamide, polyurethane, various elastomers, or the like is used. Among these, a sheet made of polyamide is preferable because it is excellent in balance between flexibility and toughness and is inexpensive.
Examples of the polyamide constituting the polyamide sheet include nylon 6, nylon 46, nylon 66, nylon 69, nylon 610, nylon 612, nylon 116, nylon 4, nylon 7, nylon 8, nylon 11, nylon 12, and the like. . Among these, nylon 6 is preferable because of excellent flexibility. Moreover, the said polyamide may be used individually by 1 type, and may use 2 or more types together.

  The thickness of the intermediate substrate 10 is preferably 25 to 100 μm, more preferably 40 to 60 μm. If the thickness of the intermediate substrate 10 is 25 μm or more, the toughness of the laminate 1 can be sufficiently secured, and if it is 100 μm or less, the flexibility of the laminate 1 can be sufficiently secured.

(Anchor layer)
The front anchor layer 20 a is a layer for increasing the adhesive strength of the ethylene resin layer 30 to the intermediate base material 10.
As the anchor agent constituting the front anchor layer 20a, an adhesive having adhesiveness to both a nonpolar resin such as polyethylene and a polar resin such as polyamide is used. Examples of the polymer having adhesiveness to both the nonpolar resin and the polar resin include polyester adhesives, acrylic adhesives, urethane adhesives, and the like.

  The thickness of the front side anchor layer 20a is preferably 1 to 10 μm, more preferably 3 to 5 μm. When the thickness of the front anchor layer 20a is 1 μm or more, the adhesive strength between the intermediate substrate 10 and the ethylene resin layer 30 can be sufficiently increased. However, even if the front-side anchor layer 20a is thicker than 10 μm, the effect of improving the adhesive strength is saturated, which is useless.

The back-side anchor layer 20 b is a layer for increasing the adhesive strength of the barrier layer 50 to the intermediate substrate 10.
As the anchor agent constituting the back anchor layer 20b, the same anchor agent as that constituting the front anchor layer 20a is used.
The thickness of the back side anchor layer 20b becomes like this. Preferably it is 1-10 micrometers, More preferably, it is 3-5 micrometers. If the thickness of the back anchor layer 20b is 1 μm or more, the adhesive strength between the intermediate substrate 10 and the barrier layer 50 can be sufficiently increased. However, even if the back anchor layer 20b is thicker than 10 μm, the effect of improving the adhesive strength is saturated, which is useless.

(Ethylene resin layer)
The ethylene-based resin layer 30 is a layer for bonding the front anchor layer 20a and the surface base material 40 together.
Examples of the ethylene resin constituting the ethylene resin layer 30 include, for example, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), ethylene / propylene copolymer, ethylene / acetic acid. Examples thereof include vinyl copolymers and ethylene / acrylic copolymers. The ethylene resin layer 30 composed of these ethylene resins is a highly flexible layer.
Among the ethylene-based resins, low-density polyethylene and linear low-density polyethylene are preferable because the laminate 1 has higher flexibility and is more excellent in curling prevention. Moreover, the said ethylene-type resin may be used individually by 1 type, and may use 2 or more types together.

  The thickness of the ethylene-based resin layer 30 is preferably 15 to 60 μm, and more preferably 20 to 50 μm. If the thickness of the ethylene resin layer 30 is 15 μm or more, the flexibility of the laminate 1 can be further increased. However, even if the ethylene-based resin layer 30 is thicker than 60 μm, not only the effect of improving the flexibility is saturated but also the flexibility may be lowered.

(Surface substrate)
The surface base material 40 has a resin sheet that is stretched in at least one direction. Specifically, a laminated sheet having a single layer uniaxially stretched sheet, a single layer biaxially stretched sheet, a uniaxially stretched sheet and / or a biaxially stretched sheet is used. Preferably, a sheet having a three-layer structure, at least one of which has a layer in which a void is formed, is preferable.
As a laminated sheet having a uniaxially stretched sheet and / or a biaxially stretched sheet, a synthetic paper having a uniaxially stretched sheet and / or a biaxially stretched sheet, a uniaxially stretched sheet and / or a biaxially stretched sheet, and an unstretched resin sheet are used. The laminated sheet which has is mentioned.
Examples of the synthetic paper include YUPO (registered trademark) made by YUPO CORPORATION in which uniaxially stretched polypropylene sheets are laminated on both sides of a biaxially stretched polypropylene sheet having voids, and Toyobo Co., Ltd., which is a biaxially stretched polyethylene terephthalate sheet having voids. Crisper ®, polypropylene layer having microvoids and Chisso calreticulin a three-layered structure sandwiched between the polypropylene layer of the imperforate (registered trademark) are commercially available.
Moreover, since the said resin sheet can prevent curl more, it is preferable to be comprised with resin which has oil resistance. Examples of the resin having oil resistance include polypropylene and polyethylene terephthalate.
Synthetic paper containing polypropylene as a main component is superior in printability and flexibility to synthetic paper containing polyethylene terephthalate as a main component, and tends to be slightly inferior in oil resistance. When comprehensively judging the advantages and disadvantages, the anti-curl property which is the effect of the present invention is excellent as shown in the examples described later.

  The exposed surface 40a of the surface substrate 40 is preferably subjected to a process for facilitating printing by various printers (for example, a thermal transfer printer, a thermal printer, an inkjet printer, etc.). Examples of the process for facilitating printing include a process for providing a recording layer, a process for providing an ink absorption layer, and a corona discharge process.

  The thickness of the surface base material 40 is preferably 25 to 120 μm, more preferably 60 to 90 μm. If the thickness of the surface base material 40 is 25 μm or more, curling of the laminate 1 can be further prevented, and if it is 120 μm or less, the flexibility becomes higher.

(Barrier layer)
The barrier layer 50 is a layer that contains a barrier resin having a low affinity for moisture and prevents entry of moisture and the like into the intermediate substrate 10.
In the present embodiment, the barrier layer 50 includes an antibacterial agent-containing layer 51 provided on the exposed surface 50a side, and an antibacterial agent-free layer 52 provided on the back anchor layer 20b side.
The antibacterial agent-containing layer 51 is a layer containing a barrier resin and an antibacterial agent.
Examples of the barrier resin include ethylene resin, vinyl chloride resin, and styrene elastomer. Among these, an ethylene-based resin is preferable in that it has a sufficient water penetration preventing property, is excellent in flexibility, and is easily embossed. Furthermore, among the ethylene-based resins, low density polyethylene is preferable because the moisture penetration preventing property is further increased.
Antibacterial agents include, for example, silver antibacterial agents such as silica gel silver, silver zeolite, calcium phosphate silver, zinc oxide antibacterial agents, benzimidazole antibacterial agents, triazine antibacterial agents, pyrithione antibacterial agents, nitrile antibacterial agents, organic Examples include iodine-based antibacterial agents.
The content of the antibacterial agent in the antibacterial agent-containing layer 51 is preferably 1 to 20% by mass and more preferably 3 to 10% by mass in the master batch. When the content of the antibacterial agent is 1% by mass or more, sufficient antibacterial properties can be exhibited. However, even if it is more than 20% by mass, the antibacterial property is saturated and is useless.

  The thickness of the antibacterial agent-containing layer 51 is preferably 15 to 60 μm, more preferably 20 to 30 μm. If the thickness of the antibacterial agent-containing layer 51 is 15 μm or more, sufficient antibacterial properties can be exerted and moisture and the like can be prevented from entering the intermediate substrate 10, and if it is 60 μm or less, the cost of the antibacterial agent is reduced. be able to.

  The antibacterial agent-free layer 52 is a layer that contains a barrier resin and does not contain an antibacterial agent. As the barrier resin contained in the antibacterial agent-free layer 52, the same barrier resin as that contained in the antibacterial agent-containing layer 51 is used. The barrier resin contained in the antibacterial agent-free layer 52 may be the same as or different from the barrier resin contained in the antibacterial agent-containing layer 51.

  The thickness of the antibacterial agent-free layer 52 is preferably 15 to 60 μm, more preferably 20 to 50 μm. If the thickness of the antibacterial agent-free layer 52 is 15 μm or more, it is possible to further prevent moisture and the like from entering the intermediate substrate 10. However, even if the antibacterial agent-free layer 52 is thicker than 60 μm, the effect of improving the moisture penetration preventing property is saturated, which is useless.

  The embossing pattern formed on the exposed surface 50a of the barrier layer 50 is not particularly limited, and examples thereof include patterns such as satin, silk, cloth, home span, wave pattern, lattice, checkered pattern, and arabesque.

(Production method)
An example of the manufacturing method of the said laminated body 1 is demonstrated.
In the manufacturing method of this example, first, the front side anchor layer 20 a is provided on one side of the intermediate base material 10.
As a method of providing the front side anchor layer 20a, for example, an application method in which an application liquid containing an anchor agent is applied to one side of the intermediate base material 10 and dried, or thermocompression bonding in which an anchor agent sheet is thermocompression bonded to the intermediate base material 10 For example, an extrusion laminating method in which an anchor agent melted by an extruder is supplied to one side of the intermediate substrate 10 can be applied.

Next, by applying an extrusion laminating method, the ethylene-based resin layer 30 is provided on the surface of the front-side anchor layer 20 a opposite to the intermediate substrate 10, and the surface substrate 40 is laminated on the ethylene-based resin layer 30.
Specifically, as shown in FIG. 2, polyethylene is melted by an extruder E ₁ , molten polyethylene is discharged from a T die D ₁ to form an ethylene-based resin layer 30, and the middle of the front-side anchor layer 20 a. Supply toward the surface opposite to the substrate 10.
Further, after supplying and superposing the surface base material 40 on the molten ethylene-based resin layer 30 supplied to the front-side anchor layer 20a, the surface base material 40 is sandwiched between a pair of rollers R ₁ and R ₂ and the layers are pressure-bonded to each other. An extruded laminate sheet 70 is obtained.

Subsequently, the back side anchor layer 20b is provided in the surface on the opposite side to the front side anchor layer 20a of the intermediate | middle base material 10 of the said extrusion lamination sheet 70. FIG. A method similar to the method of providing the front anchor layer 20a described above can be applied to the method of providing the back anchor layer 20b.
Next, as shown in FIG. 3, the resin material containing the barrier resin but not containing the antibacterial agent is melted by the first extruder E ₃ , and the molten first resin material is discharged from the T-die D _3. Thus, the antibacterial agent-free layer 52 is formed and supplied onto the back anchor layer 20b. At the same time, a resin material containing a barrier resin and an antibacterial agent is melted by the _second extruder E ₂ , and the second resin material in a molten state is discharged from the T-die D ₂ , so that the antibacterial agent-containing layer 51 is formed. It is formed and supplied on the antibacterial agent-free layer 52. In this way, the antibacterial agent-free layer 52 and the antibacterial agent-containing layer 51 are formed, and the barrier layer 50 is provided.
Thereafter, the barrier layer 50 is pressure-bonded to the extruded laminate sheet 70 via the back anchor layer 20b while being sandwiched between a pair of rolls R ₃ and R ₄ . At that time, the embossing roll R ₃ is used as a roll in contact with the barrier layer 50, and the exposed surface of the barrier layer 50 is made an embossed surface.
The laminated body 1 can be obtained by the above manufacturing method.

(Function and effect)
In the resin sheet of the surface base material 40 that is stretched in at least one direction, the molecules are oriented in the stretch direction, so that the rigidity is high and it is difficult to bend. Therefore, curling in the width direction of the wristband can be prevented while ensuring flexibility by producing the wristband from the laminate 1 so that the extending direction of the resin sheet is the width direction of the wristband.
In addition, if the resin sheet is stretched in at least one direction, the flexibility tends to be slightly impaired. However, if a material having excellent flexibility is selected for the intermediate substrate 10, the flexibility of the entire laminate 1 is It can be secured sufficiently. Moreover, in the laminated body 1 of this embodiment, since the highly flexible ethylene-type resin layer 30 is provided between the intermediate | middle base material 10 and the surface base material 40, the softness | flexibility of the laminated body 1 improves further. ing. Moreover, since the followability with respect to a deformation | transformation becomes high by providing the ethylene-type resin layer 30, it is hard to bend and generation | occurrence | production of a wrinkle can be prevented.
In addition, since the exposed surface 50a of the barrier layer 50 is an embossed surface, when the wristband is used, the contact area with the skin is small and the air permeability is high.
Moreover, since the layer of the back surface side of the laminated body 1 is the antibacterial agent containing layer 51, in the wristband produced from the laminated body 1, the surface which contacts skin can be made into the surface which has antimicrobial property. Therefore, it is possible to obtain a wristband excellent in hygiene in which bacterial growth is suppressed from the laminate 1.
Moreover, in the laminated body 1, since it has the front side anchor layer 20a between the intermediate base material 10 and the ethylene resin layer 30, the adhesive strength of the intermediate base material 10 and the ethylene resin layer 30 is high. Furthermore, since the back anchor layer 20b is provided between the intermediate substrate 10 and the barrier layer 50, the adhesive strength between the intermediate substrate 10 and the barrier layer 50 is high.

<Wristband>
An embodiment of the wristband of the present invention will be described.
The wristband of this embodiment is shown. The wristband 100 of the present embodiment example is composed of the laminate 1 described above, and the extending direction of the surface base material 40 is the width direction of the wristband.
As shown in FIG. 4, the wristband 100 according to the present embodiment includes a print area unit 110 and length adjustment units 120 a and 120 b on both sides of the print area unit 110. The wristband 100 of the present embodiment is a preferred mode because all corners are arcuate in order to prevent puncture into the skin when wrapped around the wrist or ankle.

In the print area 110 of the wristband 100 of the present embodiment, patient information such as the patient's name, sex, date of birth, and blood type is printed.
The length adjusting unit 120b is longer than the length adjusting unit 120a. One fastener fixing hole 121 is formed in the length adjusting portion 120a, and the fastener fixing holes 122, 122... Are equally spaced along the length direction in the length adjusting portion 120b. A plurality are formed.

(Wristband production method)
The wristband 100 is obtained by punching the laminate 1. Specifically, as shown in FIG. 5, the laminated body 1 has a broken line-shaped cut L that outlines a wristband 100 having a predetermined shape, so that the extending direction of the surface base material 40 is the width direction of the wristband 100. Punching process. In the illustrated example, the width direction of the surface base material 40 (the arrow direction in FIG. 5) is the stretching direction. Further, in this punching process, the hole 121 of the length adjusting portion 120a and the hole 122 of the length adjusting portion 120b are formed. Thereby, the wristband 100 is formed in the laminate 1.
Further, in the punching process, the laminated body 1 is cut outside the notch L that outlines the wristband 100 so as to obtain a band-like body 100 a having the wristband 100.

(Wristband usage)
The wristband 100 is used by the following method, for example.
First, the belt-like body 100a obtained as described above is supplied to the printer, and patient information is printed on the print area 110, and then cut along the cut L to take out the wristband 100.
Next, the wristband 100 is wound around the patient's wrist without squeezing the wrist and coming off the wrist, and the length adjustment part 120b has a plurality of holes 122, 122, .., One of the holes 122 is selected, and the hole 121 of the length adjusting unit 120a is overlaid on the hole 122.
Next, as shown in FIG. 6, the fasteners 200 are fixed to the holes 121 and 122. The fastener 200 is non-removable after fixation to prevent the wristband 100 from being removed during hospitalization. When removing the wristband 100 from the wrist, the wristband 100 is cut.

(Function and effect)
In the wristband 100, since the extending direction of the surface base material 40 of the laminate 1 described above is cut in the width direction, curling in the width direction is prevented. Accordingly, the patient information printed on the print area 110 can be easily read, and the patient's skin is hard to hit the end in the width direction, thereby preventing the patient from feeling uncomfortable.
In addition, the wristband using the laminate 1 has high flexibility, so that it does not give a sense of incongruity when worn, and also has high followability to deformation. Can keep.

<Other embodiments>
In addition, this invention is not limited to the said embodiment.
For example, in the present invention, the ethylene resin layer 30 may not be provided between the intermediate substrate 10 and the surface substrate 40. In that case, the intermediate substrate 10 and the surface substrate can be bonded together by, for example, dry lamination. However, a material bonded by dry lamination has a defect that wrinkles are likely to occur compared to a material bonded using the ethylene-based resin layer 30.
Moreover, the front side anchor layer 20a and the back side anchor layer 20b do not need to be provided in the intermediate base material 10. In that case, it is preferable that other easy adhesion treatments such as a corona discharge treatment are performed on both surfaces of the intermediate substrate 10.
Further, the exposed surface 50a of the barrier layer 50 may not be an embossed surface. Even if the exposed surface 50a of the barrier layer 50 is not an embossed surface, air permeability can be ensured by forming a large number of through holes in the wristband 100. However, when forming through holes, if the number of through holes is increased too much in order to increase the air permeability, the strength may be insufficient.
For example, when the usage period of the wristband 100 is short, the barrier layer 50 may be composed of only the antibacterial agent-free layer 52. Further, the entire barrier layer 50 may be the antibacterial agent-containing layer 51. However, if the entire barrier layer 50 is the antibacterial agent-containing layer 51, there is a disadvantage that the cost is increased.

Example 1

Next, polyethylene (Sumikasen manufactured by Sumitomo Chemical Co., Ltd.) is melted at 300 ° C. by an extruder, and the molten polyethylene is discharged from a T die to form an antibacterial agent-free layer, opposite to the nylon 6 sheet of the back anchor layer. Supplied toward the side surface.
In addition, a resin material containing polyethylene (Hirodine manufactured by Yashara Chemical Co., Ltd.) and an antibacterial agent (Daikyla (registered trademark) manufactured by Dainichi Seika Kogyo Co., Ltd.) is melted by an extruder at 260 ° C., and the molten resin material is discharged from the T die Thus, an antibacterial agent-containing layer was formed, and the barrier layer was provided by laminating and supplying the antibacterial agent-free layer on the surface opposite to the back anchor layer.
Thereafter, the barrier layer was pressure-bonded to the extruded laminate sheet by being sandwiched between a pair of rolls. In that case, the roll which contacts a barrier layer was embossed and the exposed surface of the barrier layer was made into the embossed surface.
The laminated body was obtained by the above method.
