Description

本発明は、粘着フィルムが巻回されて形成された巻回体に関する。   The present invention relates to a wound body formed by winding an adhesive film.

例えば各種の物品の包装用、接着用として、また、ラベルとして、テープ状等のフィルムの片面又は両面に一様に粘着剤を塗布した粘着フィルムが広く利用されており、通常、巻回体として、保存、流通に供され、必要な長さだけ繰り出して使用されている。
このような粘着フィルム巻回体においては、その巻回体としての形状を保つべく、また、巻回体を製造する際の巻回す作業性の点から、通常、紙管等の巻芯が中心に用いられる。
特に、粘着フィルム巻回体においては、巻回後の残留応力等に起因して変形、潰れ等が生じることがある。このような変形が生じると使用等に際して支障が生じてしまうので、変形を防止する為、巻芯には高い剛性が要求され、紙管を用いる場合にも堅牢なものが利用されている。
また、粘着フィルム巻回体の姿態を安定に保持する為に種々の提案がなされている（例えば、特許文献１参照。）
特開２００４−２６９５９２号公報 For example, adhesive films in which a pressure-sensitive adhesive is uniformly applied to one or both sides of a tape-like film are widely used for packaging and bonding various articles, and as labels, usually as wound bodies It is used for storage and distribution, and is used for the required length.
In such a pressure-sensitive adhesive film roll, in order to maintain the shape as the roll, and from the viewpoint of workability when winding the roll, usually the core of a paper tube or the like is the center. Used for.
In particular, in an adhesive film wound body, deformation, crushing, and the like may occur due to residual stress after winding. When such deformation occurs, troubles occur during use and the like. Therefore, in order to prevent deformation, the core is required to have high rigidity, and a robust one is used even when a paper tube is used.
Various proposals have been made to stably maintain the appearance of the wound adhesive film roll (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2004-269592

ところで、巻芯を有する粘着フィルム巻回体においては、使用後には、巻芯は不要となり、廃棄処分する必要が生じる。
しかしながら、巻芯には高い剛性が要求されていることから、これを潰して小さく纏めることは困難で、嵩張りやすく、廃棄処分の妨げにもなるものであった。 By the way, in the adhesive film winding body which has a winding core, a winding core becomes unnecessary after use and the necessity for disposal arises.
However, since the core is required to have high rigidity, it is difficult to squeeze it into small pieces, it is easy to bulk up, and it also hinders disposal.

本発明は前記課題を解決するためになされたもので、姿態安定性に優れ、かつ、使用済みになった後の巻芯を簡易かつ高効率で廃棄処分できる粘着フィルム巻回体を目的とする。   The present invention has been made to solve the above problems, and an object thereof is an adhesive film wound body that is excellent in form stability and that can easily and efficiently dispose of a wound core after being used. .

本発明の粘着フィルム巻回体は、円筒状の巻芯に粘着フィルムが巻回した粘着フィルム巻回体において、前記粘着フィルム巻回体の巻芯の内径の５０％変形時の圧縮荷重ｆ１［Ｎ／ｍｍ］と粘着フィルム巻回体の外径Ｒ［ｍｍ］とが次式を満たすことを特徴とするものである。
０.００５≦ｆ１／Ｒ≦０.０２０
ここで、巻芯はその内径の５０％変形時の圧縮荷重ｆ２が０.３〜３.０Ｎ／ｍｍであることが望ましい。
また、巻芯の肉厚が０.３〜６.０ｍｍであることが望ましい。
さらにまた、粘着フィルムは、フィルム上にその幅方向に対して部分的に粘着層が設けられていることが望ましく、特に、フィルムの片面上にその長さ方向に沿って帯状に粘着層が設けられ、フィルムの幅方向の長さｗに対する、粘着層の幅方向の合計長さａの比（ａ／ｗ）が、０.１〜０.７であることが望ましい。 The pressure-sensitive adhesive film wound body of the present invention is a pressure-sensitive adhesive film wound body in which a pressure-sensitive adhesive film is wound around a cylindrical core, and a compression load f 1 when the inner diameter of the core of the pressure-sensitive film wound body is deformed by 50%. [N / mm] and the outer diameter R [mm] of the wound adhesive film satisfy the following formula.
0.005 ≦ f 1 /R≦0.020
Here, the core is preferably compression load f 2 at 50% deformation of the inner diameter of 0.3~3.0N / mm.
Moreover, it is desirable that the thickness of the core is 0.3 to 6.0 mm.
Furthermore, it is desirable that the adhesive film is provided with an adhesive layer partially on the film in the width direction, and in particular, the adhesive layer is provided in a band shape along the length direction on one side of the film. The ratio (a / w) of the total length a in the width direction of the adhesive layer to the length w in the width direction of the film is preferably 0.1 to 0.7.

本発明の粘着フィルム巻回体によれば、必要十分な姿態安定性をもち、使用性、外観性等において良好でありながら、使用済みになった巻芯を容易に小型化できて廃棄処分効率を高めることができる。   According to the pressure-sensitive adhesive film roll of the present invention, it has a necessary and sufficient form stability and is good in usability, appearance and the like, but can easily reduce the size of a used core and dispose of it efficiently. Can be increased.

図１は本発明の粘着フィルム巻回体の一例を示すもので、円筒状の巻芯１２を中心にして、テープ状の粘着フィルム１４が幾重にも巻回されて構成されている。
本発明においては、巻芯１２の内径（内周縁の直径）ｒが５０％になるように粘着フィルム巻回体１０を圧縮変形させた時の圧縮荷重ｆ１［Ｎ／ｍｍ］と、粘着フィルム巻回体１０の外径（外周縁の直径）Ｒ［ｍｍ］とが次式を満たすことが必要である。
０.００５≦ｆ１／Ｒ≦０.０２０
ここで、圧縮荷重とは、図５に示すように、測定対象となる粘着フィルム巻回体１０を測定台２０上に横倒して固定し、粘着フィルム巻回体の上部から押圧板２２を下降させて圧縮し、巻芯１２の内径が負荷前の内径の半分になったときの荷重を測定するものである。
ｆ１／Ｒが０.００５以上であることにより、巻芯が粘着フィルムの巻回圧力に対して変形せず、粘着フィルム巻回体として、その形状を維持し、しかも、巻芯が５０％変形するような外力が加わった後でも、その解放後に断面形状が復元し、使用に際して支障が生じることがない。他方、ｆ１／Ｒが０.０２０以下であることにより、粘着フィルムを全て繰り出して使用済みになって残った巻芯を人が手作業で簡易に握り潰して小型化することができる。この要件を満たす為には、例えば、巻芯の材質、厚み、構造等を適宜調整すればよい。 FIG. 1 shows an example of the pressure-sensitive adhesive film roll according to the present invention, and a tape-like pressure-sensitive adhesive film 14 is wound around a cylindrical core 12 in layers.
In the present invention, the compression load f 1 [N / mm] when the pressure-sensitive adhesive film roll 10 is compressed and deformed so that the inner diameter (inner peripheral diameter) r of the core 12 is 50%, and the pressure-sensitive adhesive film It is necessary that the outer diameter (the diameter of the outer peripheral edge) R [mm] of the wound body 10 satisfy the following formula.
0.005 ≦ f 1 /R≦0.020
Here, as shown in FIG. 5, the compressive load means that the pressure-sensitive adhesive film roll 10 to be measured is fixed on the measurement table 20 while being laid down, and the pressing plate 22 is lowered from the upper part of the pressure-sensitive adhesive film roll. The load is measured when the inner diameter of the core 12 becomes half of the inner diameter before loading.
When f 1 / R is 0.005 or more, the core does not deform with respect to the winding pressure of the adhesive film, maintains its shape as an adhesive film winding body, and the core is 50%. Even after an external force that deforms is applied, the cross-sectional shape is restored after the release, and there is no trouble in use. On the other hand, when f 1 / R is 0.020 or less, it is possible to easily reduce the size of the wound core that is left after being used by feeding out the entire adhesive film by hand. In order to satisfy this requirement, for example, the material, thickness, structure, and the like of the core may be adjusted as appropriate.

巻芯１２は、紙製、プラスチック製等、巻芯として利用でき且つ廃棄処分適性があれば、その材質は特に制限されるものではない。
さらに、巻芯の内径の５０％変形時の圧縮荷重ｆ２は０.３〜３.０Ｎ／ｍｍであることが望ましい。圧縮荷重ｆ２が０.３Ｎ／ｍｍ以上であることにより、姿態安定性が向上し、圧縮荷重ｆ２が３.０Ｎ／ｍｍ以下であることにより、手作業により容易に潰し易くなるからである。
巻芯の大きさについては、その目的等に応じて決められ、幅はこれに巻回する粘着フィルに応じ、太さは直径が１ｃｍのものから１ｍのもの等が利用される。３〜２０ｃｍのものが広く利用される。
また、巻芯の肉厚ｔは０.３〜６.０ｍｍであることが望ましい。巻芯は、上記要件を満たすものであれば、できるだけ薄い方が省資源、廃棄物削減等の理由から望ましく、実際上、この範囲のものが（特に紙管においては）適切かつ現実的だからである。 The material of the core 12 is not particularly limited as long as it can be used as a core such as paper or plastic and is suitable for disposal.
Furthermore, the compressive load f 2 at 50% deformation of the inner diameter of the winding core is preferably a 0.3~3.0N / mm. This is because when the compressive load f 2 is 0.3 N / mm or more, the form stability is improved, and when the compressive load f 2 is 3.0 N / mm or less, it is easily crushed by hand. .
The size of the core is determined according to the purpose and the like, the width is based on the adhesive film wound around the core, and the thickness is from 1 cm to 1 m in diameter. A thing of 3-20 cm is widely used.
Further, it is desirable that the thickness t of the core is 0.3 to 6.0 mm. As long as the core satisfies the above requirements, it is desirable to make it as thin as possible for reasons such as saving resources and reducing waste. In practice, this range is appropriate and practical (especially in paper tubes). is there.

粘着フィルム１４は、フィルムの片面又は両面に粘着層が設けられて概略構成される。
フィルムの材質、大きさは、その粘着フィルムの用途等に応じて適宜選択される。材質としては、例えば、ポリオレフィン（ポリエチレン、ポリプロピレン等）、軟質ポリ塩化ビニル、ポリエチレンテレフタレート等のポリエステルなどが挙げられる。大きさについても、幅が２ｃｍ位のものから１ｍ位のものが適用できる。５〜３０ｃｍのものが広く利用される。長さも、１ｍ位から１００ｍのもののように、特に限られない。
フィルムは単層の他、必要に応じて複数層から構成される。例えば、粘着層の設けられない側には、離型層等が設けられうる。また、フィルムには、必要に応じて、印刷や表面処理等も施される。 The adhesive film 14 is generally configured by providing an adhesive layer on one or both sides of the film.
The material and size of the film are appropriately selected according to the use of the adhesive film. Examples of the material include polyolefin (polyethylene, polypropylene, etc.), soft polyvinyl chloride, polyester such as polyethylene terephthalate, and the like. As for the size, those having a width of about 2 cm to about 1 m can be applied. The thing of 5-30 cm is widely used. The length is not particularly limited as well, such as from 1 m to 100 m.
In addition to a single layer, the film is composed of a plurality of layers as required. For example, a release layer or the like can be provided on the side where the adhesive layer is not provided. The film is also subjected to printing, surface treatment, and the like as necessary.

粘着層に用いる粘着剤の種類や塗布量は、本発明の趣旨を逸脱しない範囲内で、その用途等に応じて決められる。例えば、シリコーン系、アクリル系、天然ゴム系、合成ゴム系（スチレン−イソプレン−スチレンブロック共重合体、スチレン−ブタジエン−スチレンブロック共重合体、イソプレンゴム、ポリイソブチレン、ブチルゴム等）など、若しくは、これらの混合系の各種の粘着剤が挙げられる。
粘着層の厚さは３−４０μｍが適当であり、１０−３０μｍが好ましい。十分な粘着力を発揮させ易く、他方、粘着剤の凝集力が過剰にならず、巻芯が変形せず、粘着剤が粘着フィルムの全体に均一に設けられていない場合にでも、粘着剤のある場所とない場所とで巻径差が小さく、皺が生じにくいからである。 The kind and application amount of the pressure-sensitive adhesive used for the pressure-sensitive adhesive layer are determined according to the application and the like within a range not departing from the gist of the present invention. For example, silicone, acrylic, natural rubber, synthetic rubber (styrene-isoprene-styrene block copolymer, styrene-butadiene-styrene block copolymer, isoprene rubber, polyisobutylene, butyl rubber, etc.) or the like Various pressure-sensitive adhesives of the mixed system are mentioned.
The thickness of the adhesive layer is suitably 3-40 μm, and preferably 10-30 μm. It is easy to exert sufficient adhesive force. On the other hand, even if the cohesive force of the adhesive does not become excessive, the core does not deform, and the adhesive is not uniformly provided on the entire adhesive film, This is because the difference in winding diameter is small between a certain place and no place, and wrinkles are less likely to occur.

上述した本発明の要件を満たす為には、フィルムに対する粘着層を設ける範囲、位置にを特定することが効果的である。即ち、フィルムの面の全面に設けるのではなく、その幅方向（繰り出し方向に対して垂直な方向）に対して部分的に粘着層を設ける。例えば、図２に示すように、フィルム１４の両側縁近傍部分にその長さ方向に沿って帯状に粘着層１６を設け、中央部分に粘着層のない部分を設けることで、フィルム１４の幅方向に対して部分的に粘着層１６を設ける。このように、粘着層１６を全体に渡ってではなく、部分的に設けることにより、巻芯１２が通常の巻芯に比して圧縮強さが小さくても、巻芯が潰れにくくなり、変形しにくくなる。その理由は明らかではないが、粘着フィルムは粘着層を設けることにより、僅かに可撓性が失われるようになるが、これが巻回体とした際には、その巻数に応じて可撓性の損失が増大する。そのようなものであると、巻回体にかかる外力、又は、粘着フィルムの内部応力が、巻芯に大きくかかり、巻芯の陥没、変形をもたらし易くなる。しかしながら、本発明のように、粘着層のない部分が確保されることにより、全体として粘着フィルムが柔軟になり、外力や内部応力を粘着フィルム自体が吸収し、巻芯への負荷が低減され、巻芯の陥没、変形が抑制されると共に、粘着フィルムが弾性復帰し、円筒状に維持され易くなるものと考えられる。
粘着層１６は、その幅方向の長さｗに対する、粘着層１６の幅方向の長さａ（複数箇所に分かれている場合はその合計：ａ＝ａ1＋ａ２）の比（ａ／ｗ）が、０.１〜０.７が好ましく、０.２〜０.５がより好ましく、０.３〜０.４が望ましい。下限値よりも小さいと、用途にもよるが、十分な粘着力が確保しづらくなり、上限値よりも大きいと巻芯の変形防止作用が小さくなるからである。
粘着層１６は、図２に示す例のように、両側に２本設けるものに限られない。例えば、図３に示すように、両側縁部分を残して中央部分のみに１本の粘着層１６を設けたり、また、図４に示すように、両側縁部分と中央部分を残して２本の粘着層１６、１６を設けたりすることができる。粘着層１６の本数も３本以上であってもよく、また、帯状でなくても良い。
このような粘着層を設ける場所、幅等は、粘着フィルムを用いる目的、用途、必要な接着強度等を考慮して決められる。 In order to satisfy the above-described requirements of the present invention, it is effective to specify the range and position where the adhesive layer for the film is provided. That is, it is not provided on the entire surface of the film, but an adhesive layer is partially provided in the width direction (direction perpendicular to the feeding direction). For example, as shown in FIG. 2, the adhesive layer 16 is provided in a strip shape along the length direction in the vicinity of both side edges of the film 14, and the portion without the adhesive layer is provided in the central portion, thereby In contrast, the adhesive layer 16 is partially provided. Thus, by providing the adhesive layer 16 partially rather than over the entire core, the core is less likely to be crushed and deformed even if the core 12 has a lower compressive strength than a normal core. It becomes difficult to do. The reason for this is not clear, but the adhesive film slightly loses flexibility by providing an adhesive layer. However, when this is used as a wound body, the adhesive film has a flexibility depending on the number of turns. Loss increases. In such a case, the external force applied to the wound body or the internal stress of the adhesive film is greatly applied to the core, and the core is likely to be depressed and deformed. However, as in the present invention, by ensuring a portion without the adhesive layer, the adhesive film becomes flexible as a whole, the adhesive film itself absorbs external force and internal stress, and the load on the core is reduced, It is considered that the depression and deformation of the core are suppressed, and the adhesive film is elastically restored and easily maintained in a cylindrical shape.
The pressure-sensitive adhesive layer 16 has a ratio (a / w) of the length a in the width direction of the pressure-sensitive adhesive layer 16 to the length w in the width direction (a = a 1 + a 2 in the case where the pressure layer is divided into a plurality of locations). However, 0.1 to 0.7 is preferable, 0.2 to 0.5 is more preferable, and 0.3 to 0.4 is desirable. This is because if it is smaller than the lower limit, depending on the application, it is difficult to ensure a sufficient adhesive force, and if it is larger than the upper limit, the effect of preventing the deformation of the core is reduced.
The adhesive layer 16 is not limited to two provided on both sides as in the example shown in FIG. For example, as shown in FIG. 3, one adhesive layer 16 is provided only in the central portion leaving both side edge portions, or two side edge portions and the central portion are left as shown in FIG. The adhesive layers 16 and 16 can be provided. The number of the pressure-sensitive adhesive layers 16 may be three or more, and may not be a belt shape.
The place, width, and the like where such an adhesive layer is provided are determined in consideration of the purpose and application of the adhesive film, the required adhesive strength, and the like.

本発明の粘着フィルム巻回体を製造するのにも、特殊な工法は必要とせず、従来周知の方法を利用でき、安価かつ容易に製造できる。   In order to manufacture the pressure-sensitive adhesive film roll of the present invention, a special method is not required, and a conventionally known method can be used, and it can be manufactured inexpensively and easily.

以下、本発明をより具体的に説明する。尚、圧縮荷重試験は「テンシロンRTC-1310A」エー・アンド・デー社製を用いて上記方法により行ったもので、その圧縮速度は、粘着フィルム巻回体について測定するときは５０ｍｍ／分とし、巻芯について測定するときは１０ｍｍ／分とした。
［実施例１］

また、図２に示すように、幅ｗが８０ｍｍ、厚さが３０μｍのＯＰＰ製のテープ状フィルムの片面上に、その両側縁近傍部分に帯状（ａ１＝ａ２＝１０ｍｍ ａ／ｗ＝０.２５）の天然ゴム系粘着剤からなる粘着層１６（塗布厚１５μｍ）を設けた粘着フィルム１４を準備した。
巻取装置を利用し、そのエアシャフトを上記紙管に挿入、固定し、エアシャフトを回転させて粘着フィルム１４を紙管上に、その直径が、粘着層１６が設けられている両側縁近傍部分において８０ｍｍになるように巻き取って粘着フィルム巻回体を製造した。
この粘着フィルム巻回体を観察したが、紙管に陥没はなく、全体として円筒状で使用に際して支障がなく、また、圧縮荷重試験後においても形状が復元し、良好なものであった。 Hereinafter, the present invention will be described more specifically. The compression load test was performed by the above method using “Tensilon RTC-1310A” manufactured by A & D, and the compression speed was 50 mm / min when measuring the wound adhesive film, When measuring about the winding core, it was set to 10 mm / min.
[Example 1]

When the compression load was measured for this paper tube, it was 0.33 N / mm at 25% compression and 0.42 N / mm at 50% compression. Note that this paper tube was easily crushed when it was intentionally crushed by hand.
Further, as shown in FIG. 2, on one side of an OPP tape-like film having a width w of 80 mm and a thickness of 30 μm, strips are formed in the vicinity of both side edges (a 1 = a 2 = 10 mm a / w = 0). A pressure-sensitive adhesive film 14 provided with a pressure-sensitive adhesive layer 16 (coating thickness: 15 μm) made of natural rubber pressure-sensitive adhesive of .25) was prepared.
Using a winding device, the air shaft is inserted into and fixed to the paper tube, and the air shaft is rotated to place the adhesive film 14 on the paper tube, and its diameter is in the vicinity of both side edges where the adhesive layer 16 is provided. The pressure-sensitive adhesive film roll was manufactured by winding up to 80 mm in the portion.
This adhesive film wound body was observed, but there was no depression in the paper tube, and it was cylindrical as a whole, and there was no hindrance in use, and the shape was restored even after the compression load test, and it was good.
