Description

  The present invention relates to a method for producing an adhesive tape. More specifically, the present invention relates to a pressure-sensitive adhesive tape manufacturing method comprising a pressure-sensitive adhesive layer formed in a predetermined pattern on a support, and a pressure-sensitive adhesive tape manufactured using the manufacturing method.

  Conventionally, an adhesive tape has been used for the purpose of fixing, protecting, marking, and stimulating various things. This pressure-sensitive adhesive tape always has a pressure-sensitive adhesive layer made of a pressure-sensitive adhesive, but there are various tapes in which the shape of the pressure-sensitive adhesive layer is devised according to the purpose of application and the type of adherend. For example, body protection, meridian distortion correction, acupuncture stimulation, slimming, fascia and muscle function recovery, bone and joint function recovery, tendon position correction, body massage, body warming, stiffness of shoulders, pain, inflammation, etc. Adhesive tape used in the fields of relief, taping, beauty, body affected area treatment, folk remedies, etc. is applied directly to the body, so the adhesive layer is patterned into a predetermined shape to prevent stuffiness and rash, Some of them ensure air permeability.

  In addition to the adhesive tape used for the body, for example, the adhesive tape used for temporary fixation, short-time protection, or mark is formed with an adhesive layer on the entire surface of the support to improve the peelability. In some cases, the pressure-sensitive adhesive layer is patterned into a predetermined shape on the support.

  As a specific example, for example, Patent Document 1 discloses a pressure-sensitive adhesive tape having improved air permeability by forming a pressure-sensitive adhesive layer on the tape in a wavy shape. Patent Document 2 discloses an adhesive sheet in which a predetermined concave pattern is formed on an adhesive layer. Furthermore, in Patent Document 3, a plurality of concave grooves extending in the tape width direction are arranged at intervals in the longitudinal direction of the tape, and concave grooves having different lengths are formed in the longitudinal direction of the tape. A body affixing tape having an array configuration consisting of a pattern row that gradually becomes longer and shorter is disclosed.

  These adhesive tapes are conventionally produced as follows. For example, the pressure-sensitive adhesive tape described in Patent Document 1 applies a pressure-sensitive adhesive paint to one surface of a traveling temporary base sheet so as to form a pressure-sensitive adhesive paint layer, and is perpendicular to the traveling direction of the temporary base sheet. Using a comb having a plurality of scraping legs that reciprocate in the direction of the surface, part of the pressure-sensitive adhesive paint layer is scraped off and dried, and the pressure-sensitive adhesive paint layer remaining on the temporary substrate sheet is dried. After forming the pressure-sensitive adhesive layer, a pressure-sensitive adhesive sheet is produced by transferring the wave-like pressure-sensitive adhesive layer to a support. This method involves applying a pressure-sensitive adhesive paint on the entire surface of one surface of the temporary base sheet, and then scraping and removing a portion of the pressure-sensitive adhesive paint layer with a comb having a scraping foot. The pressure-sensitive adhesive paint layer that could not be removed remained on the pressure-sensitive adhesive sheet after transfer, causing a decrease in air permeability.

  Moreover, for example, the pressure-sensitive adhesive sheet described in Patent Document 2 supplies a base film having a pressure-sensitive adhesive layer or a release paper having a pressure-sensitive adhesive layer between an embossing roll having a convex portion of a predetermined pattern on the surface and a flat roll. Then, the pressure-sensitive adhesive sheet is manufactured by pressing at least under the condition where the concave portion forming auxiliary liquid is interposed in the convex portion to form a predetermined pattern of concave portions in the adhesive layer. In this method as well, as in Patent Document 1, an adhesive layer that cannot be removed by the convex portion remains on the adhesive sheet, causing the adhesive to remain or a thin film, which causes a decrease in air permeability. Moreover, since the high cost is anticipated for preparation of the embossing roll which has a convex part, the problem which also increases the manufacturing cost of adhesive sheet itself has arisen.

JP 2006-75648 A JP 2006-299123 A JP 2006-175093 A

  As described above, in the conventional manufacturing method of the pressure-sensitive adhesive tape in which the pressure-sensitive adhesive layer is patterned in a predetermined shape on the support, the air permeability is lowered due to the residual pressure-sensitive adhesive in the part that does not originally have the pressure-sensitive adhesive layer. There was a problem of doing. Further, in the method using a roll mold (such as a mold or an embossing roll), since the mold preparation is expensive, there is a problem that the manufacturing cost of the pressure-sensitive adhesive sheet itself increases.

  Therefore, in the present invention, it is possible to ensure that the adhesive does not remain in a portion that does not have the adhesive layer when the adhesive layer having a predetermined shape is formed on the support by simply passing through a simple process. The main object is to provide a method for producing an adhesive tape.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described with reference to the drawings. In addition, embodiment described below shows an example of typical embodiment of this invention, and, thereby, the range of this invention is not interpreted narrowly.

<Manufacturing method of adhesive tape>
FIG. 1 is a flow diagram of a method for manufacturing an adhesive tape 10 according to the present invention, and FIG. 2 is a view from the adhesive layer 11 side of a support 13 in the adhesive tape 10 manufactured by the manufacturing method according to the present invention. FIG. 3 is a schematic front view, and FIG. 3 is a schematic diagram showing an example of a manufacturing apparatus 100 for the pressure-sensitive adhesive tape 10 used in the manufacturing method according to the present invention.

  The method for producing the pressure-sensitive adhesive tape 10 according to the present invention is a method for producing the pressure-sensitive adhesive tape 10 in which a pattern is formed by a pressure-sensitive adhesive layer 11 and a non-pressure-sensitive adhesive layer 12 on a support 13 as shown in FIG. This is a method of performing at least the (I) pressure-sensitive adhesive application step, (II) the pressure-sensitive adhesive removing sheet first lamination step, and (III) the pressure-sensitive adhesive transfer step. Moreover, it is also possible to perform (IV) sheet peeling process, (V) through-hole formation process, (VI) adhesive removal sheet peeling process, and (VII) adhesive removal sheet 2nd lamination process as needed. is there. Hereinafter, each step will be described in detail.

(I) Adhesive Application Step The adhesive application step (I) is a step of applying an adhesive to the sheet 15. As the sheet 15 to which the adhesive is applied, a sheet 15 having a through hole 14 having the same shape as the non-adhesive layer 12 is used. The sheet 15 may be provided with the through-holes 14 in advance, or the sheet 15 without the through-holes 14 may be formed by forming the through-holes 14 through a (V) through-hole forming step described later. May be.

  The specific method of applying the adhesive to the sheet 15 is not particularly limited, and any known application method can be freely selected and used. For example, the manufacturing apparatus 100 as shown in FIG. 3 is used to discharge the adhesive from the head 101 to the first surface of the sheet 15 or to apply the adhesive to the first surface of the sheet 15 with a brush or a spatula (not shown). It can be done by wearing it.

(II) Adhesive Removal Sheet First Laminating Step The adhesive removing sheet first laminating step (II) includes the second surface opposite to the first surface of the sheet 15, that is, the adhesive layer 11 of the sheet 15. This is a step of laminating the pressure-sensitive adhesive removing sheet 16a on the surface not to be used. As shown in FIG. 1, the pressure-sensitive adhesive removing sheet first lamination step (II) may be performed after the pressure-sensitive adhesive application step (I) or before the pressure-sensitive adhesive application step (I). It is possible to exert the effect of.

  In the pressure-sensitive adhesive application step (I), since the pressure-sensitive adhesive is applied to the first surface of the sheet 15 having the through-holes 14, the pressure-sensitive adhesive enters the through-holes 14 or the pressure-sensitive adhesive passes through the through-holes 14. It may leak out to two sides. The pressure-sensitive adhesive that has entered the through-hole 14 or leaked to the second surface of the sheet 15 is preliminarily laminated on the second surface of the sheet 15 or is laminated after the pressure-sensitive adhesive application step. It is possible to remove it.

  This will be described more specifically with reference to FIG. FIG. 4 is a schematic cross-sectional view showing the state of the sheet 15, the pressure-sensitive adhesive A, the pressure-sensitive adhesive removal sheet 16 a, and the support 13 in each step of the manufacturing method according to the present invention. For example, when the adhesive is applied from the head 101 toward the first surface side 151 (upper side in the drawing) of the sheet 15 using the manufacturing apparatus 100 as shown in FIG. 3 (see FIG. 4A). 4) When the adhesive A enters the through hole 14 as shown in FIG. 4B, or the adhesive A leaks to the second surface 152 (lower side in the drawing) of the sheet 15 through the through hole 14. There is. When the adhesive is transferred to the support 13 in the adhesive transfer step (III) described later in this state, the non-adhesive layer 12 on the support 13 is not formed into a desired shape, resulting in a decrease in air permeability or adhesion. It may cause a change in force.

  Therefore, as shown in FIG. 4C, the adhesive removal sheet 16 a is laminated from the second surface 152 (lower side in the drawing) of the sheet 15 to enter the through hole 14 or the second surface of the sheet 15. The pressure-sensitive adhesive A that has leaked to 152 can be adhered to the pressure-sensitive adhesive removal sheet 16a. And at the time of sticking of an adhesive tape or in the (VI) adhesive removal sheet peeling process mentioned later, as shown in FIG.4 (d), by peeling the adhesive removal sheet 16a from the sheet | seat 15, it penetrates into the through-hole 14. The adhesive A that has leaked to the second surface 152 of the dripping sheet 15 can be reliably removed. Therefore, the pressure-sensitive adhesive A can be pattern-formed only on portions other than the through holes 14 on the first surface 151 of the sheet 15. And in this state, if the adhesive is transferred to the support 13 by the adhesive transfer step (III) described later (see FIGS. 4 (e) and (f)), the adhesive A entering the through hole 14 is Transfer to the support 13 can be prevented, and as a result, the non-adhesive layer 12 on the support 13 can be secured, and a reduction in air permeability and a change in adhesive force can be prevented.

(III) Adhesive Transfer Step The adhesive transfer step (III) is a step of laminating the support 13 on the first surface 151 of the sheet 15 and transferring the adhesive A to the support 13. The adhesive A that has entered the through hole 14 of the sheet 15 is removed from the sheet 15 by being adhered to the adhesive removal sheet 16a through the (II) adhesive removal sheet first lamination step. Therefore, the first surface 151 of the sheet 15 is in a state where the adhesive A is applied only to the portion other than the through holes 14 (see FIG. 4D). By laminating the support 13 on the first surface 151 of the sheet 15 and transferring the adhesive A to the support 13, a pattern composed of the adhesive layer 11 and the non-adhesive layer 12 is formed on the support 13. be able to.

  More specifically, for example, as shown in FIG. 3, the sheet 15 that has undergone the pressure-sensitive adhesive application step (I) and the pressure-sensitive adhesive removal sheet first lamination step (II) passes through a drying furnace 102 as necessary. Thus, after the adhesive A applied to the first surface 151 of the sheet 15 is dried, the support 13 is laminated from the first surface 151 (upper side in the drawing) of the sheet 15 (FIG. 4E The adhesive A on the sheet 15 can be transferred to the support 13 by pressing with a pair of rollers 103 facing each other (see FIG. 4F).

  Further, for example, although not shown, the sheet 15 that has undergone the pressure-sensitive adhesive application step (I) and the pressure-sensitive adhesive removal sheet first lamination step (II) is supported from the first surface 151 (upper side in the drawing) of the sheet 15. 13 (see FIG. 4 (e)), and after passing the drying furnace 102 as necessary, the first surface 151 of the sheet 15 and the pressure-sensitive adhesive A sandwiched between the supports are dried, and then facing each other. The pressure-sensitive adhesive A on the sheet 15 can be transferred to the support 13 by pressing with a pair of rollers 103 or the like (see FIG. 4F).

  In FIG. 4, the support 14 is laminated on the sheet 15 after the adhesive removal sheet 16 a is peeled from the sheet 15, but the present invention is not limited to this. For example, as shown in FIGS. 5D and 5E, the support 13 is stacked on the first surface 151 of the sheet 15 while the adhesive removing sheet 16 a is stacked on the sheet 15, and the adhesive is applied to the support 13. It is also possible to achieve the object of the present invention by transferring A and then peeling off the adhesive removing sheet 16 together with the sheet 15 (see FIG. 5F).

(IV) Sheet peeling process Sheet peeling process (IV) is a process of peeling the sheet | seat 15 from the support body 14 after performing an adhesive transfer process (III) (refer FIG. 1 and FIG. 6). The sheet 15 used in the production method according to the present invention can be used as the release sheet 15 ′ of the pressure-sensitive adhesive tape 10 when the sheet release process (IV) is not performed, but by performing the sheet release process (IV). The sheet 15 can be used repeatedly for the production of the adhesive tape 10.

  The material for forming the sheet 15 is not particularly limited, and any material conventionally used in the field of adhesive tape or any material used in the adhesive tape manufacturing process can be freely selected and used. For example, one or two types of paper, synthetic resin film, foamed sheet, silicon, rubber, metal foil, wood, glass fiber, or those obtained by processing polytetrafluoroethylene fluororesin (Teflon (registered trademark)). It can be used in combination of more than one species.

  When the sheet peeling step (IV) is performed, in order to repeatedly use the sheet 15, the sheet made of any of the above materials is surface-treated with polytetrafluoroethylene fluororesin (Teflon (registered trademark)). That is particularly preferred.

  When the sheet 15 is used as the release sheet 15 ′ of the pressure-sensitive adhesive tape 10 without performing the sheet peeling step (IV), it is preferable to use a sheet made of paper, a synthetic resin film, a foamed sheet, or the like.

  When performing sheet peeling process (IV), as shown in FIG. 6, after sheet peeling process (IV), in order to protect the adhesive layer 11 at the time of distribution | circulation and storage, you may laminate | stack peeling sheet 15 '. . The release sheet 15 ′ in this case may be provided with the through hole 14 or may be a release sheet having a shape that is normally used without the through hole 14. The release sheet 15 ′ may be the same sheet as the sheet 15, or may be a sheet made of a different material such as a sheet made of a material thinner than the sheet 15.

(V) Through-hole forming step The through-hole forming step (V) is a step of forming the through-hole 14 in the sheet 15. Although it is not an essential step in the production method according to the present invention, it is performed before the pressure-sensitive adhesive coating step (I) (see FIGS. 1 and 7), and even the sheet 15 having no through hole 14 is produced according to the present invention. The method can be used.

  The method for forming the through hole 14 is not particularly limited, and any known method can be freely selected and used. For example, as shown in FIG. 7, when the sheet 15 passes through the pattern processing machine 104, the sheet 15 is cut into a predetermined shape using a flat plate or roll mold, puncher, blade, laser, or the like. The through-hole 14 can be formed in.

(VI) Adhesive Removal Sheet Peeling Step The adhesive removal sheet peeling step (VI) is a step of peeling the pressure sensitive adhesive removal sheet 16a from the sheet 15 after going through the pressure sensitive adhesive removal sheet first lamination step (II). is there. Although not an essential step in the production method according to the present invention, the adhesive removal sheet peeling step (VI) is performed after the pressure-sensitive adhesive removal sheet first lamination step (II) (see FIGS. 1 and 8). The adhesive A that has entered the through hole 14 or leaked to the second surface of the sheet 15 can be more reliably removed from the sheet 15. And it can prevent that the adhesive A which penetrated into the through-hole 14 is transcribe | transferred to the support body 13, As a result, the non-adhesive layer on the support body 13 is ensured, air permeability fall or It is possible to prevent a change in adhesive force.

  For example, as shown in FIG. 8, the adhesive A that has entered the through-hole 14 or leaked to the second surface 152 of the sheet 15 is subjected to the adhesive removal sheet first laminating step (II). After making it adhere to the removal sheet 16a, it can carry out by winding up the adhesive removal sheet 16a.

  In FIG. 8, the pressure-sensitive adhesive removal sheet peeling step (VI) is performed immediately after the pressure-sensitive adhesive removal sheet first lamination step (II), but the present invention is not limited to this. At least after the pressure-sensitive adhesive removal sheet first lamination step (II), for example, as shown in FIG. 1, the pressure-sensitive adhesive removal sheet peeling step (VI) may be performed after the pressure-sensitive adhesive transfer step (III). Be free.

  Further, in the manufacturing method according to the present invention, after the pressure-sensitive adhesive removing sheet peeling step (VI), the roller 105 as shown in FIG. It is also possible to more reliably remove the adhesive A leaking to the surface from the sheet 15.

(VII) Adhesive Removal Sheet Second Lamination Step The adhesive removal sheet second lamination step (VII) is performed on the second surface 152 of the sheet 15 after passing through the adhesive removal sheet peeling step (VI). This is a step of laminating the removal sheet 16b. The pressure-sensitive adhesive removing sheet 16b used in the pressure-sensitive adhesive removing sheet second lamination step (VII) may be the same sheet as the pressure-sensitive adhesive removing sheet 16a used in the pressure-sensitive adhesive removing sheet first lamination step (II), For example, you may use the sheet | seat which consists of a different raw material like the sheet | seat which consists of a raw material thinner than the adhesive removal sheet | seat 16a used by the said adhesive removal sheet 1st lamination | stacking process (II). Although not an essential step in the production method according to the present invention, when the pressure-sensitive adhesive removal sheet peeling step (VI) is performed, the pressure-sensitive adhesive removal sheet second lamination step (VII) is performed (see FIGS. 1 and 9). In particular, when the sheet 15 is caused to function as the release sheet 15 ′, the following effects can be achieved.

  Since the sheet 15 used in the manufacturing method according to the present invention includes the through holes 14, when the sheet 15 is used as the release sheet 15 ′, the adhesive A flows over time in the manufacturing process and the distribution process of the adhesive tape. Thus, the adhesive A may enter the through hole 14 or the adhesive A may leak through the through hole 14 to the second surface 152 of the release sheet 15 ′. Thus, the adhesive A that has entered the through-hole 14 or leaked to the second surface 152 of the release sheet 15 ′ in the manufacturing process or the distribution process of the adhesive tape is the adhesive removal sheet second lamination step (VII). By performing this, the pressure-sensitive adhesive removing sheet 16b can be adhered. Then, the adhesive A that has entered the through hole 14 is prevented from being transferred to the support 13 by peeling the adhesive removal sheet 16b together with the release sheet 15 ′ when the adhesive tape is applied to the adherend. can do. As a result, a non-adhesive layer on the support 13 is secured, and a decrease in air permeability and a change in adhesive force can be prevented.

  In addition, by laminating the adhesive removing sheet 16b on the second surface 152 of the release sheet 15 ′, when the adhesive tape 10 is circulated or stored in a rolled state or in a laminated state, the release sheet 15 ′ It is also possible to prevent the adhesive A leaking to the two surfaces 152 from adhering to the support 13 and binding between the adhesive tapes 10.

  Furthermore, since the sheet 15 of the pressure-sensitive adhesive tape 10 according to the present invention is provided with the through-hole 14, when the sheet 15 is used as the release sheet 15 ′, the pressure-sensitive adhesive tape 10 is cut according to the shape of the adherend. In particular, there is a case where the scrap of the release sheet 15 ′ increases at the time of sticking, or the complexity that the cut release sheet 15 ′ has to be peeled off increases. However, by laminating the adhesive removal sheet 16b on the release sheet 15 ′, it is possible to prevent the waste of the release sheet 15 ′ from increasing at the time of application, and the release sheet 15 ′ is peeled off at the same time together with the adhesive removal sheet 16b. Therefore, it is possible to reduce complexity at the time of sticking.

  In FIG. 9, the adhesive removal sheet second lamination step (VII) is performed after the adhesive transfer step (III). However, the present invention is not limited to this. At least after the pressure-sensitive adhesive removal sheet peeling step (VI), for example, the pressure-sensitive adhesive removal sheet second lamination step (VII) may be performed before the pressure-sensitive adhesive transfer step (III) as shown in FIG. The pressure-sensitive adhesive removing sheet second lamination step (VII) can be performed simultaneously with the pressure-sensitive adhesive transfer step (III).

  If the adhesive tape manufactured using the manufacturing method which concerns on this invention demonstrated above is manufactured using the manufacturing method which concerns on this invention, the final form of a distribution stage will not be specifically limited. For example, after passing through each of the necessary steps, the sheet 15 having the through-holes 14 can be peeled from the support 13 and circulated in a state of being replaced with a commonly used release sheet '.

<Adhesive tape>
FIG. 10 is a schematic cross-sectional view showing an embodiment of the pressure-sensitive adhesive tape 10 according to the present invention, and FIG. 11 is a schematic front view of the pressure-sensitive adhesive tape 10 according to the present invention as viewed from the pressure-sensitive adhesive removal sheet 16 side. The pressure-sensitive adhesive tape 10 according to the present invention roughly comprises a support 13, a release sheet 15 ′, and a pressure-sensitive adhesive removal sheet 16.

(1) Support 13
The support 13 of the pressure-sensitive adhesive tape 10 according to the present invention has a pattern including a pressure-sensitive adhesive layer 11 and a non-pressure-sensitive adhesive layer 12 formed on one side. Since the entire surface is provided with the non-adhesive layer 12 without being covered with the adhesive layer 11, the air permeability can be ensured when the adhesive tape 10 is applied to the adherend. Further, by adjusting the ratio of the pressure-sensitive adhesive layer 11 and the non-pressure-sensitive adhesive layer 12, it is also possible to adjust the adhesive strength in accordance with the type of adherend and the purpose of application.

  The shape of the pattern composed of the pressure-sensitive adhesive layer 11 and the non-pressure-sensitive adhesive layer 12 is not particularly limited, and can be freely designed according to the form of the pressure-sensitive adhesive tape 10, the type of adherend, the purpose of application, and the like. For example, not only the pattern shown in FIG. 2, the pattern shown in FIG. 12 or 13, a polygon such as a triangle, a rectangle, a rhombus, a pentagon, and a hexagon, a circle, an ellipse, or a combination of these shapes, Examples of the pattern include a wave shape, a zigzag shape, a zigzag shape, and a lattice shape.

  The material for forming the support 13 is not particularly limited, and any material conventionally used in the field of adhesive tape can be freely selected and used. For example, a woven fabric such as cotton fabric, a nonwoven fabric, a knitted fabric, paper, a synthetic resin film, a foamed sheet, a polymer sheet, or the like can be used alone or in combination.

  In the present invention, a material having flexibility and stretchability is particularly preferable from the viewpoint of adaptability to the adherend. Further, when the pressure-sensitive adhesive tape according to the present invention is used for a living body, a material having air permeability is preferable in order to prevent skin respiration and stuffiness.

  The kind of the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer 11 is not particularly limited, and a pressure-sensitive adhesive that can be used for a known pressure-sensitive adhesive tape can be freely selected and used. For example, pressure sensitive adhesives such as natural rubber, synthetic rubber, acrylic, urethane, vinyl ether, silicone, water, emulsion, and UV can be used.

(3) Adhesive removal sheet 16
One feature of the pressure-sensitive adhesive tape 10 according to the present invention is that a pressure-sensitive adhesive removing sheet 16 is laminated on a release sheet 15 ′. Since the release sheet 15 ′ of the pressure-sensitive adhesive tape 10 according to the present invention is provided with the through holes 14, the pressure-sensitive adhesive A that forms the pressure-sensitive adhesive layer flows over time in the manufacturing process and distribution process of the pressure-sensitive adhesive tape 10. Thus, the adhesive A may enter the through hole 14 or the adhesive A may leak through the through hole 14 to the second surface 152 of the release sheet 15 ′. In this way, by providing the adhesive removal sheet 16 with the adhesive A that has entered the through hole 14 or leaked to the second surface 152 of the release sheet 15 ′ in the manufacturing process or distribution process of the adhesive tape 10, The pressure-sensitive adhesive A is adhered to the pressure-sensitive adhesive removing sheet 16, and the pressure-sensitive adhesive A that has entered the through hole 14 is peeled off when the pressure-sensitive adhesive tape 10 is adhered to the adherend, and the pressure-sensitive adhesive removing sheet 16 is peeled off together with the release sheet 15 ′. Can be prevented from being transferred to the support 13. As a result, a non-adhesive layer on the support 13 is secured, and it is possible to prevent a decrease in air permeability, a change in adhesive force, a bias in force for grasping the skin, and the like.

  In addition, by laminating the pressure-sensitive adhesive removing sheet 16 on the second surface 152 of the release sheet 15 ′, when the adhesive tape 10 is circulated or stored in a rolled state or in a laminated state, the first of the release sheet 15 ′ It is also possible to prevent the adhesive tapes 10 from being bound to each other by the adhesive A leaking to the two surfaces 152.

  Further, since the release sheet 15 ′ of the pressure-sensitive adhesive tape 10 according to the present invention is provided with a through hole 14, it is particularly affixed when the pressure-sensitive adhesive tape 10 is cut and used in accordance with the shape of the adherend. Occasionally, the scrap of the release sheet 15 ′ may increase, or the complexity of having to release each of the cut release sheets 15 ′ may increase. However, by laminating the pressure-sensitive adhesive removal sheet 16 on the release sheet 15 ′, it is possible to prevent the waste of the release sheet 15 ′ from increasing at the time of sticking, and the release sheet 15 ′ is peeled off at the same time together with the pressure-sensitive adhesive removal sheet 16. Therefore, it is possible to reduce complexity at the time of sticking.

  The material for forming the pressure-sensitive adhesive removing sheet 16 is not particularly limited, and any material conventionally used in the field of pressure-sensitive adhesive tapes can be freely selected and used. For example, paper, a synthetic resin film, a foam sheet, a polymer sheet, or the like can be used alone or in combination of two or more.

  In the present invention, the material forming the pressure-sensitive adhesive removal sheet 16 is preferably a transparent material from the viewpoint of confirming the flow state of the pressure-sensitive adhesive A into the through hole 14 and from the viewpoint of design.

  The use of the pressure-sensitive adhesive tape 10 according to the present invention described above is not particularly limited, and the pressure-sensitive adhesive tape 10 according to the present invention can be suitably used in all fields using the pressure-sensitive adhesive tape. The pressure-sensitive adhesive tape according to the present invention is provided with the non-pressure-sensitive adhesive layer 12 on which the pressure-sensitive adhesive A does not remain at all on the support 13, so that air permeability is ensured and the adhesive force can be easily adjusted. It is. Therefore, it can be preferably used particularly when the living body is an adherend.

  The pressure-sensitive adhesive tape manufactured using the manufacturing method according to the present invention is surely provided with the non-pressure-sensitive adhesive layer 12 on which the pressure-sensitive adhesive A does not remain on the support 13, so that air permeability is reliably ensured. The adhesive strength can be easily adjusted. Therefore, it can be suitably used in any field where an adhesive tape is used.
