Description
本考案は、基材、粘着剤層、および剥離ライナーが積層された帯状貼付材を巻芯に巻回してなる帯状貼付材の巻回体に関するものである。 The present invention relates to a wound body of a band-shaped patch made by winding a band-shaped patch on which a base material, an adhesive layer, and a release liner are laminated, around a core.
一般的に、基材、粘着剤層、および剥離ライナーが積層された帯状貼付材を巻芯に巻回する際には、巻芯から帯状貼付材が滑り落ちないように巻き初めの帯状貼付材の始端部を巻芯に固定する必要がある。帯状貼付材の始端部を巻芯に固定する方法としては、巻芯表面全体にあらかじめ粘着剤層が形成されたものを使用することによって貼付材の始端部を固定する方法（特許文献１参照）、或いは、粘着テープを使用して貼付材の始端部を巻芯に固定する方法（特許文献２参照）が用いられている。 Generally, when a band-shaped patch having a base material, a pressure-sensitive adhesive layer, and a release liner laminated thereon is wound around a core, the band-shaped patch at the beginning of winding is prevented from slipping off from the core. It is necessary to fix the starting end of the wire to the core. As a method of fixing the starting end of the band-shaped patch to the core, a method of fixing the starting end of the patch by using an adhesive layer formed in advance on the entire surface of the core (see Patent Document 1). Or the method (refer patent document 2) which fixes the starting end part of a sticking material to a core using an adhesive tape is used.
しかしながら、前者の巻芯表面全体にあらかじめ粘着剤層が形成されたものを使用する方法では、巻芯表面自体に粘着性が付与されているために、粘着性を有する巻芯表面が作業者の手や指等にくっ付き、巻芯を取り扱う際の作業性が悪くなる場合があった。また、巻芯表面全体に粘着剤層が形成されたものをそのままの状態で保管すると、保管中に巻芯表面全体に形成された粘着剤層にゴミ等が付着するおそれがあり、衛生的に良くないものであった。
一方、後者の粘着テープを使用する方法では、粘着テープを貼付して貼付材を巻芯に固定した後ロール状に巻回すると、巻芯近傍の貼付材は貼付した粘着テープの形状に変形し（写り込み）、見映えの良くない貼付材が得られる場合があった。また、粘着テープを用いて貼付材の始端部を巻芯に固定するためには、粘着テープを適当な長さに切断し貼付材の始端部と巻芯に貼り付けるといった余計な作業が必要であった。
However, in the former method in which the pressure-sensitive adhesive layer is formed on the entire core surface in advance, the core surface itself has an adhesive property. In some cases, it may stick to a hand or a finger, resulting in poor workability when handling the core. In addition, if the material with the pressure-sensitive adhesive layer formed on the entire surface of the core is stored as it is, dust or the like may adhere to the pressure-sensitive adhesive layer formed on the entire surface of the core during storage. It was not good.
On the other hand, in the method using the latter adhesive tape, when the adhesive tape is affixed and the adhesive is fixed to the core and then wound into a roll, the adhesive near the core is deformed into the shape of the adhesive tape applied. In some cases, a sticking material with poor appearance was obtained. Moreover, in order to fix the starting end of the adhesive material to the core using the adhesive tape, an extra work such as cutting the adhesive tape to an appropriate length and attaching it to the starting end of the adhesive material and the core is necessary. there were.
本考案は、このような事情に鑑みてなされたものであり、基材、粘着剤層、および剥離ライナーが積層された帯状貼付材を、巻芯に巻回してなる帯状貼付材の巻回体に関するものであって、帯状貼付材の始端部を巻芯に簡便に固定、巻回することができるとともに、貼付材の変形（写り込み）がなく、見映えの良い帯状貼付材の巻回体を提供することにある。 The present invention has been made in view of such circumstances, and a wound body of a band-shaped patch made by winding a band-shaped patch on which a base material, an adhesive layer, and a release liner are laminated, around a core. A wound body of a belt-like patch that can be easily fixed and wound on the core of the belt-like patch, and has no appearance (reflection) and has a good appearance. Is to provide.
本考案は、上記の課題を解決するために鋭意検討して見出したものであり、下記に示すとおりである。
（１）基材、粘着剤層、および剥離ライナーがこの順で積層された帯状貼付材を巻芯に巻回してなる帯状貼付材の巻回体であって、巻芯と帯状貼付材との間に接着層を備えていることを特徴とする帯状貼付材の巻回体。
（２）接着層を構成する材料がホットメルト材料である（１）に記載の帯状貼付材の巻回体。
（３）接着層の厚みが、１μｍ〜４０μｍである（１）に記載の帯状貼付材の巻回体。
（４）接着層の平面形状が、巻芯表面の幅方向における接着層の長さ（Ｗ）と、巻芯表面の巻き方向における接着層の長さ（Ｌ）により形成される略矩形状であって、巻芯表面の幅方向における接着層の長さ（Ｗ）が、巻芯表面の全幅（Ｗ０）に対して５０％〜１００％を満足する長さであり、巻芯表面の巻き方向における接着層の長さ（Ｌ）が、３ｍｍ以上、且つ、巻芯表面の巻き方向全周長（Ｌ０）に対して１〜１００％を満足する長さである、（１）に記載の帯状貼付材の巻回体。
The present invention has been found by intensive studies to solve the above-described problems, and is as follows.
(1) A wound body of a band-shaped patch prepared by winding a band-shaped patch having a base material, a pressure-sensitive adhesive layer, and a release liner laminated in this order on a winding core. A wound body of a band-shaped patch having an adhesive layer therebetween.
(2) The wound body of the band-shaped patch according to (1), wherein the material constituting the adhesive layer is a hot melt material.
(3) The wound body of the band-shaped patch according to (1), wherein the adhesive layer has a thickness of 1 μm to 40 μm.
(4) The planar shape of the adhesive layer is a substantially rectangular shape formed by the length (W) of the adhesive layer in the width direction of the core surface and the length (L) of the adhesive layer in the winding direction of the core surface. The length (W) of the adhesive layer in the width direction of the core surface is a length that satisfies 50% to 100% with respect to the entire width (W 0 ) of the core surface, The length (L) of the adhesive layer in the direction is 3 mm or more, and the length satisfying 1 to 100% with respect to the entire circumferential length (L 0 ) of the winding core surface, according to (1) A wound body of band-like patch material.
基材、粘着剤層、および剥離ライナーが積層された帯状貼付材を巻芯に巻回する直前に、巻芯と帯状貼付材との間に接着層を形成した後、帯状貼付材の始端部を、前記接着層を介して巻芯に軽く押し当てることで、帯状貼付材の始端部を簡便に巻芯に固定することができる。これによって、粘着テープを貼付する等の作業を省略することができ、帯状貼付材を巻芯に固定するための作業性が大幅に向上する。また、粘着テープを貼付するという作業自体を省略することができるだけでなく、巻芯近傍の帯状貼付材が、粘着テープを貼り付けて巻芯に固定する場合のような粘着テープの形状に変形する（写り込む）ことはないため、見映えの良い帯状貼付材の巻回体を得ることができる。さらに、帯状貼付材の始端部を巻芯へ固定する際に、巻芯と帯状貼付材との微妙な位置合わせを簡単に行うことができるため、帯状貼付材を巻芯へ固定する際の貼付ズレを防止することができる。そして、巻芯には帯状貼付材を巻回する直前まで接着層が形成されないので、巻芯を保管する際にゴミが付着するおそれはないし、作業する手や指等にくっ付くこともないので、巻芯を取扱いする際の作業性が格段に優れる。 Immediately before winding the band-shaped patch on which the base material, the pressure-sensitive adhesive layer, and the release liner are laminated, the adhesive layer is formed between the core and the band-shaped patch, and then the start end of the band-shaped patch Is lightly pressed against the core via the adhesive layer, so that the starting end of the band-shaped patch can be easily fixed to the core. As a result, work such as sticking the adhesive tape can be omitted, and workability for fixing the belt-like sticking material to the core is greatly improved. Moreover, not only can the work of attaching the adhesive tape itself be omitted, but also the band-like adhesive material in the vicinity of the core is transformed into the shape of the adhesive tape as in the case where the adhesive tape is applied and fixed to the core. Since it is not reflected, it is possible to obtain a wound body of a band-like patch having a good appearance. Furthermore, since the delicate alignment between the core and the strip-shaped patch can be easily performed when fixing the starting end of the strip-shaped patch to the core, it is possible to apply the paste when fixing the strip-shaped patch to the core. Misalignment can be prevented. And since the adhesive layer is not formed on the core until just before winding the band-shaped patch, there is no risk of dust adhering to the core when it is stored, and it will not stick to the hands or fingers that you work on. Workability when handling the core is remarkably excellent.
本考案の帯状貼付材の巻回体は、帯状貼付材を所望の長さに引き出し切断することによって使用することができ、特に医療衛生分野およびスポーツ分野等の皮膚を被着体とする皮膚貼付材として好適に使用されるものである。そして、本考案の帯状貼付材の巻回体は、帯状貼付材を巻芯に巻回する際に滑り落ちることなく巻芯に固定し、巻回することができるように、帯状貼付材と巻芯との間に接着層を備えていることを特徴とするものである。帯状貼付材は巻芯との間に形成された接着層を介して簡便に巻芯に固定され、巻回されることによって本考案の帯状貼付材の巻回体が得られる。 The wound body of the band-like patch of the present invention can be used by pulling and cutting the band-like patch to a desired length, and in particular, the skin patch with the skin in the medical hygiene field and sports field as an adherend. It is suitably used as a material. And the wound body of the strip-shaped adhesive material of the present invention is fixed to the core without slipping down when the strip-shaped adhesive material is wound around the core, and can be wound. And an adhesive layer. The strip-shaped patch is simply fixed to the core via an adhesive layer formed between the core and wound to obtain the wound body of the strip-shaped patch of the present invention.
本考案の接着層に用いられる材料としては、加熱や押圧によって流動性が生じる特性を示すとともに、巻芯や貼付材との接着性が良好な特性を示すものが好適に使用される。
このような特性を示す材料としては、ホットメルト材料が挙げられるが、さらに詳細には、ゴム系、アクリル系、ポリオレフィン系、ポリウレタン系、ポリアミド系、およびエチレン−酢酸ビニル系からなる群から選ばれる１種以上からなるホットメルト材料が用いられる。中でも、ゴム系ホットメルト材料が好ましく用いられ、さらに、ゴム系ホットメルト材料の中でも、スチレン−イソプレンブロック共重合体、スチレン−ブタジエンブロック共重合体、スチレン−エチレン−ブチレンブロック共重合体及びスチレン−エチレン−プロピレンブロック共重合体からなる群から選ばれる１種以上を主成分とするベースポリマーからなるスチレン系ホットメルト材料が、加熱や押圧によって流動性が生じるため、より一層好ましく用いられる。
As the material used for the adhesive layer of the present invention, a material that exhibits the property that fluidity is generated by heating or pressing, and that exhibits good properties of adhesiveness to the core or the patch is preferably used.
Examples of the material exhibiting such characteristics include hot melt materials, and more specifically, selected from the group consisting of rubber-based, acrylic-based, polyolefin-based, polyurethane-based, polyamide-based, and ethylene-vinyl acetate-based materials. One or more hot melt materials are used. Among these, rubber-based hot melt materials are preferably used. Among rubber-based hot melt materials, styrene-isoprene block copolymers, styrene-butadiene block copolymers, styrene-ethylene-butylene block copolymers, and styrene- A styrenic hot melt material composed of a base polymer composed mainly of one or more selected from the group consisting of ethylene-propylene block copolymers is more preferably used because it generates fluidity by heating or pressing.
ホットメルト材料の軟化点としては、通常、６０〜１８０℃、好ましくは８０〜１５０℃である。軟化点が１８０℃を超えるホットメルト材料は、加熱溶融させるのに特別な加熱装置が必要になり、実用的ではない。また、軟化点が６０℃未満のホットメルト材料では、常温放置でも流動しやすいため、このような材料にて形成された接着層はべたつく等、使用に際して使いづらいことがある。 The softening point of the hot melt material is usually 60 to 180 ° C, preferably 80 to 150 ° C. A hot-melt material having a softening point exceeding 180 ° C. is not practical because a special heating device is required for heating and melting. In addition, hot melt materials having a softening point of less than 60 ° C. tend to flow even at room temperature, so that an adhesive layer formed of such materials is sticky and may be difficult to use.
接着層の厚みは、巻芯や貼付材に対する接着性と、接着層による貼付材の変形（写り込み）を防止する観点で、適切な範囲に設定される。すなわち、接着層の厚みは、好ましくは１μｍ〜４０μｍであり、より好ましくは２μｍ〜３０μｍである。接着層の厚みが１μｍ未満だと巻芯や貼付材に対する接着性が十分でなく、固定できないおそれがある。一方、接着層の厚みが４０μｍを超えると、貼付材を構成する基材の種類や厚みによっては、貼付材の表面に凹凸が発生し写り込みが生じる可能性がある。なお、基材と粘着剤層の積層体である一般的な粘着テープと違い、本考案に用いられる接着層は、押圧によって変形するため、接着層の厚みが少々厚くても、接着層による貼付材の変形（写り込み）は起こりにくい。 The thickness of the adhesive layer is set to an appropriate range from the viewpoint of adhesiveness to the core and the adhesive material and preventing deformation (reflection) of the adhesive material by the adhesive layer. That is, the thickness of the adhesive layer is preferably 1 μm to 40 μm, more preferably 2 μm to 30 μm. If the thickness of the adhesive layer is less than 1 μm, the adhesiveness to the core or the patch is not sufficient, and there is a possibility that it cannot be fixed. On the other hand, when the thickness of the adhesive layer exceeds 40 μm, depending on the type and thickness of the base material constituting the adhesive material, irregularities may occur on the surface of the adhesive material, and reflection may occur. Note that, unlike a general adhesive tape that is a laminate of a base material and an adhesive layer, the adhesive layer used in the present invention is deformed by pressing. Deformation (reflection) of the material is unlikely to occur.
本考案の接着層は、巻芯に帯状貼付材をしっかりと固定するために一定の面積を有する平面形状からなる。すなわち、接着層の平面形状は、巻芯表面の幅方向における接着層の長さ（Ｗ）と、巻芯表面の巻き方向における接着層の長さ（Ｌ）により形成される略矩形状であって、巻芯表面の幅方向における接着層の長さ（Ｗ）が巻芯表面の全幅（Ｗ０）に対して５０％〜１００％を満足する長さであり、巻芯表面の巻き方向における接着層の長さ（Ｌ）が３ｍｍ以上、且つ、巻芯表面の巻き方向全周長（Ｌ０）に対して１〜１００％を満足する長さであることが好ましい。さらに、巻芯に帯状貼付材を固定する際に、固定位置の微調整を簡便に行う観点から、巻芯表面の巻き方向における接着層の長さ（Ｌ）は３ｍｍ以上、且つ、巻芯表面の巻き方向全周長（Ｌ０）に対して１〜４０％を満足する長さであることがより好ましい。このような平面形状を有する接着層は、巻芯の表面に複数形成されても良い。
巻芯表面の幅方向における接着層の長さ（Ｗ）が、巻芯全幅（Ｗ０）に対して５０％未満の場合には、接着面積が小さすぎるため、場合によっては巻芯に帯状貼付材を適切に固定することができないおそれがある。同様に、巻芯表面の巻き方向における接着層の長さ（Ｌ）が３ｍｍ未満の場合も、適切に固定することができない場合がある。一方、巻芯表面の巻き方向における接着層の長さ（Ｌ）が、巻芯表面の巻き方向全周長（Ｌ０）に対して１００％を超えると、巻芯表面の巻き方向全周長を超えて接着層が形成されるため、経済的に不利である。
The adhesive layer of the present invention has a planar shape having a certain area in order to firmly fix the belt-like patch to the winding core. That is, the planar shape of the adhesive layer is a substantially rectangular shape formed by the length (W) of the adhesive layer in the width direction of the core surface and the length (L) of the adhesive layer in the winding direction of the core surface. Thus, the length (W) of the adhesive layer in the width direction of the core surface is a length that satisfies 50% to 100% with respect to the entire width (W 0 ) of the core surface, and in the winding direction of the core surface. The length (L) of the adhesive layer is preferably 3 mm or more and a length satisfying 1 to 100% with respect to the entire circumferential length (L 0 ) of the winding core surface. Furthermore, from the viewpoint of easily performing fine adjustment of the fixing position when fixing the belt-like patch to the core, the length (L) of the adhesive layer in the winding direction of the core surface is 3 mm or more, and the core surface It is more preferable that the length satisfies 1 to 40% with respect to the entire circumference in the winding direction (L 0 ). A plurality of adhesive layers having such a planar shape may be formed on the surface of the core.
When the length (W) of the adhesive layer in the width direction of the surface of the core is less than 50% with respect to the total width (W 0 ) of the core, the adhesive area is too small. The material may not be properly fixed. Similarly, when the length (L) of the adhesive layer in the winding direction on the surface of the core is less than 3 mm, it may not be able to be fixed properly. On the other hand, when the length (L) of the adhesive layer in the winding direction of the core surface exceeds 100% with respect to the total circumferential length (L 0 ) of the core surface, the total circumferential length of the core surface in the winding direction This is economically disadvantageous because the adhesive layer is formed beyond the above.
本考案の接着層は、帯状貼付材を巻芯に巻回する直前に形成させることが好ましい。接着層は帯状貼付材に形成させても良いし、巻芯に形成させても良いが、作業性の観点から、巻芯に形成させる方がより好ましい。
また、巻芯に接着層を形成させた後、帯状貼付材を巻芯に固定し巻回する際に、帯状貼付材を構成する基材または剥離ライナーのどちらを外側にして巻回しても良く、帯状貼付材の用途や材料等を考慮して適宜決定することができる。
The adhesive layer of the present invention is preferably formed immediately before the belt-like patch is wound around the core. The adhesive layer may be formed on the belt-like patch or may be formed on the core, but it is more preferable to form it on the core from the viewpoint of workability.
In addition, after the adhesive layer is formed on the winding core, when the band-shaped patch is fixed to the core and wound, it may be wound with either the substrate constituting the band-shaped patch or the release liner facing outside. It can be appropriately determined in consideration of the use and material of the band-like patch.
帯状貼付材を構成する基材は、様々な用途に用いられている一般的な基材を使用することができる。構造に関しては、織布、不織布、編布、紙等の繊維の集合体類、および多孔シート、通気性シート等のシート状物などが例示される。また、材料に関しては、ナイロン、ポリエステル、ポリエチレン、ポリプロピレン、ポリウレタン、セルロース等の合成あるいは天然の有機高分子類が例示される。 The base material which comprises a strip | belt-shaped adhesive material can use the general base material used for various uses. Examples of the structure include aggregates of fibers such as woven fabric, nonwoven fabric, knitted fabric, and paper, and sheet-like materials such as a porous sheet and a breathable sheet. Examples of the material include synthetic or natural organic polymers such as nylon, polyester, polyethylene, polypropylene, polyurethane, and cellulose.
特に、医療衛生分野およびスポーツ分野等の貼付材のように皮膚を被着体とする場合には、通気性もしくは透湿性を有し、且つ、防水性を有するものが好適に使用される。このような基材としては、水の接触角が大きくて水に濡れ難い材料からなる多孔シート、或いは水に濡れ易い材料からなる多孔シート、それを撥水処理したもの、等が挙げられる。水に濡れ難い材料の多孔シートとしては、例えば、ポリエチレン、ポリプロピレン、ポリブテン、エチレン−プロピレン共重合体、エチレン−酢酸ビニル共重合体、エチレン−エチルアクリレート共重合体等のポリオレフィン類、或いはポリウレタン、ポリエステル、ポリアミド等のその他のプラスチック類などの有機高分子からなる穿孔フィルム、連続気泡を有する発泡シート、織物、不織布、編物、紙等が挙げられる。水に濡れ易い材料からなる多孔シートとしては、木綿、セルロース、ポリビニルアルコール等の有機高分子類からなる織物、不織布、編物、紙、ポリビニルアルコールの穿孔フィルム等が挙げられる。水に濡れ易い材料からなる多孔シートは、粘着剤層未形成面に一般的に知られている撥水剤にて撥水処理して使用される。なお、上記の水に濡れ難い材料の多孔シートも必要に応じて撥水処理して使用される。基材は、非伸縮性であっても良く、また縦方向および／または横方向に伸縮性を有するものであっても良い。 In particular, when the skin is an adherend, such as a patch in the medical hygiene field and sports field, a material having air permeability or moisture permeability and waterproof is preferably used. Examples of such a substrate include a porous sheet made of a material that has a large contact angle with water and hardly wets with water, a porous sheet made of a material that easily gets wet with water, and a water-repellent treated product thereof. Examples of porous sheets made of materials that are difficult to wet with water include polyolefins such as polyethylene, polypropylene, polybutene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, and ethylene-ethyl acrylate copolymer, or polyurethane and polyester. And a perforated film made of an organic polymer such as other plastics such as polyamide, a foamed sheet having open cells, a woven fabric, a nonwoven fabric, a knitted fabric, and paper. Examples of the porous sheet made of a material that easily wets water include woven fabrics, nonwoven fabrics, knitted fabrics, paper, and a perforated film of polyvinyl alcohol made of organic polymers such as cotton, cellulose, and polyvinyl alcohol. A porous sheet made of a material that easily wets water is used after being subjected to water repellent treatment with a generally known water repellent on the surface where the pressure-sensitive adhesive layer is not formed. In addition, the porous sheet of the material which does not easily get wet with water is used after being subjected to water repellent treatment as necessary. The base material may be non-stretchable, and may be stretchable in the vertical direction and / or the horizontal direction.
基材の厚みは、材質、用途等によって適宜、決定することが好ましいが、通常、フィルムを基材とする場合には、１０〜２５０μｍが好ましく、１０〜１００μｍがさらに好ましい。また、織布や不織布等の布帛や紙などを基材とする場合には、５０〜５００μｍが好ましく、１００〜３００μｍがさらに好ましい。なお、後者のような布帛、紙等を基材に用いる場合には、絶対厚みを測定することが困難な場合もあるので、坪量が８〜２００ｇ／ｍ２のものを用いることが好適である。 The thickness of the substrate is preferably determined as appropriate depending on the material, application, and the like. Usually, when a film is used as the substrate, 10 to 250 μm is preferable, and 10 to 100 μm is more preferable. Moreover, when using as a base material fabrics, such as a woven fabric and a nonwoven fabric, and paper, 50-500 micrometers is preferable and 100-300 micrometers is more preferable. When using the latter fabric, paper or the like as the base material, it may be difficult to measure the absolute thickness, so it is preferable to use one having a basis weight of 8 to 200 g / m 2. is there.
帯状貼付材を構成する粘着剤層に用いられる粘着剤は、一般的に用いられているものを用途に応じて適宜使用することができる。具体的には、天然ゴム系粘着剤、合成ゴム系粘着剤、アクリル系粘着剤、シリコーン系粘着剤、ビニルエーテル系粘着剤、ビニルエステル系粘着剤粘着剤、ポリエステル系粘着剤、ウレタン系粘着剤等の粘着剤を用いることができ、これらは単独でまたは複数以上組み合わせて使用される。また、医療衛生分野およびスポーツ分野等の貼付材において使用される場合には、被着体である皮膚に対して刺激が少ない材質が好適に使用される。 As the pressure-sensitive adhesive used for the pressure-sensitive adhesive layer constituting the belt-like patch, a generally used pressure-sensitive adhesive can be appropriately used depending on the application. Specifically, natural rubber adhesives, synthetic rubber adhesives, acrylic adhesives, silicone adhesives, vinyl ether adhesives, vinyl ester adhesive adhesives, polyester adhesives, urethane adhesives, etc. These pressure-sensitive adhesives can be used, and these are used alone or in combination. In addition, when used in a patch material in the medical hygiene field or sports field, a material that is less irritating to the skin as the adherend is preferably used.
粘着剤層には上記粘着剤以外に、必要に応じて、各種添加剤を含有させることができる。添加剤としては、例えば、可塑剤、架橋剤、粘着付与剤、酸化防止剤、耐熱安定剤、光安定剤、帯電防止剤、滑剤、核剤、難燃剤、顔料、染料、薬剤等が挙げられ、粘着剤層中にこれらを単独または複数以上含んでも良い。 In addition to the above-mentioned pressure-sensitive adhesive, various additives can be contained in the pressure-sensitive adhesive layer as necessary. Examples of the additives include plasticizers, crosslinking agents, tackifiers, antioxidants, heat stabilizers, light stabilizers, antistatic agents, lubricants, nucleating agents, flame retardants, pigments, dyes, drugs, and the like. The pressure-sensitive adhesive layer may contain one or more of these.
粘着剤層の厚みは、使用部位や粘着剤の種類によって適宜決定することができるが、１０μｍ〜３００μｍが好ましく、２０μｍ〜２００μｍがより好ましい。粘着剤層の厚みが１０μｍ未満だと被着体との粘着力不足により貼付中に貼付材が剥がれるおそれがある。一方、粘着剤層の厚みが３００μｍを超えると貼付材の端部から粘着剤がはみ出して糊汚れが生じる可能性がある。 Although the thickness of an adhesive layer can be suitably determined with the use site | part and the kind of adhesive, 10 micrometers-300 micrometers are preferable and 20 micrometers-200 micrometers are more preferable. If the thickness of the pressure-sensitive adhesive layer is less than 10 μm, the adhesive material may be peeled off during application due to insufficient adhesion with the adherend. On the other hand, when the thickness of the pressure-sensitive adhesive layer exceeds 300 μm, the pressure-sensitive adhesive protrudes from the edge of the patch, and there is a possibility that paste stains will be generated.
帯状貼付材に用いられる剥離ライナーは一般的に使用されるものを適用することができるが、経済性を考慮すると紙製の剥離ライナーを用いることが好ましい。紙製の剥離ライナーとしては、例えば、上質紙、グラシン紙、パーチメント紙の表面に、シリコーン樹脂やフッ素樹脂等の剥離性能を有する剥離剤をコーティングしたものなどが挙げられる。なお、接着層を介して帯状貼付材の剥離ライナー側を巻芯に固定する場合は、片面剥離処理された剥離ライナーを採用し、剥離処理を施していない面を接着層に当接させることによって、しっかり固定することができる。 As the release liner used for the band-shaped patch, a commonly used release liner can be applied, but in consideration of economy, it is preferable to use a paper release liner. Examples of the paper release liner include those obtained by coating the surface of high-quality paper, glassine paper, and parchment paper with a release agent having release performance such as silicone resin and fluorine resin. In addition, when fixing the release liner side of the belt-like patch to the core via the adhesive layer, adopt a release liner that has been subjected to a single-sided release treatment, and bring the surface that has not been subjected to the release treatment into contact with the adhesive layer. Can be fixed firmly.
