Description

本発明は、２枚のフィルムが積層され、両フィルムを引き剥がすことにより、２枚のタックラベルを得ることができる積層ラベルに関する。   The present invention relates to a laminated label in which two films are laminated and two tack labels can be obtained by peeling off both films.

従来、第１フィルムの一面に、第１フィルムの長手方向に延びる帯状の剥離層と帯状の粘着層が、第１フィルムの幅方向に交互に設けられ、且つ、第２フィルムの一面に、第２フィルムの長手方向に延びる帯状の剥離層と帯状の粘着層が、第２フィルムの他方向に交互に設けられており、前記第１フィルムの剥離層が前記第２フィルムの粘着層に対面し、且つ前記第１フィルムの粘着層が前記第２フィルムの剥離層に対面するように、第１フィルムと第２フィルムが重ね合わされている積層ラベルが知られている。
このような積層ラベルは、特許文献１に開示されている。 Conventionally, a strip-shaped release layer and a strip-shaped adhesive layer extending in the longitudinal direction of the first film are alternately provided on one surface of the first film in the width direction of the first film, and The strip-shaped release layer and the strip-shaped adhesive layer extending in the longitudinal direction of the two films are alternately provided in the other direction of the second film, and the release layer of the first film faces the adhesive layer of the second film. And the lamination label with which the 1st film and the 2nd film were overlaid is known so that the adhesion layer of the said 1st film may face the peeling layer of the said 2nd film.
Such a laminated label is disclosed in Patent Document 1.

かかる積層ラベルは、第１フィルムと第２フィルムが、それぞれの剥離層と粘着層を対面させて重ね合わされているので、第１フィルムと第２フィルムを容易に引き剥がすことができる。
引き剥がした第１フィルム及び第２フィルムは、それぞれの幅方向に間隔を隔てて粘着層が設けられているので、該粘着層を介して、容器などの被貼付体に貼り付けることができる。そして、該第１フィルム及び第２フィルムに、所望の印刷などを施すことにより、両フィルムを表示用のタックラベルとして使用することができる。
特開平６−２７４１０４号公報 In such a laminated label, since the first film and the second film are overlapped with each of the release layer and the adhesive layer facing each other, the first film and the second film can be easily peeled off.
Since the peeled first film and the second film are provided with an adhesive layer at intervals in the respective width directions, the first film and the second film can be attached to an adherend such as a container via the adhesive layer. And both films can be used as a tack label for a display by giving desired printing etc. to this 1st film and 2nd film.
JP-A-6-274104

しかしながら、上記従来の積層ラベルは、第１フィルムまたは第２フィルムの少なくとも何れか一方の側部には、粘着層が設けられていないので、該側部が被貼付体に接着せず、不用意に捲れ易いという問題点がある。
具体的には、第１フィルムの一方の側部に、剥離層が設けられている場合、これに対面する第２フィルムの一方の側部には、粘着層が設けられている。また、第１フィルムの他方の側部に、粘着層が設けられている場合、これに対面する第２フィルムの他方の側部には、剥離層が設けられている。このため、第１フィルムと第２フィルムを引き剥がすと、第１フィルムの一方の側部及び第２フィルムの他方の側部には、粘着層が存在せず、従って、第１フィルムの一方の側部及び第２フィルムの他方の側部が、被貼付体に接着しない。このため、第１フィルムの一方の側部及び第２フィルムの他方の側部が、捲れ易く、その結果、前記フィルムの側部が折れたり、前記フィルムの側部を始点としてフィルムが被貼付体から大きく剥がれるなどの問題を生じる。 However, since the above conventional laminated label is not provided with an adhesive layer on at least one side of the first film or the second film, the side does not adhere to the adherend and is inadvertent. There is a problem that it is easy to drown.
Specifically, when a release layer is provided on one side of the first film, an adhesive layer is provided on one side of the second film facing the first film. Moreover, when the adhesion layer is provided in the other side part of the 1st film, the peeling layer is provided in the other side part of the 2nd film which faces this. For this reason, when the first film and the second film are peeled off, there is no adhesive layer on one side of the first film and the other side of the second film. The side part and the other side part of the second film do not adhere to the adherend. For this reason, the one side part of the first film and the other side part of the second film are easy to squeeze, and as a result, the side part of the film is broken, or the film is to be adhered starting from the side part of the film. This causes problems such as peeling off from the surface.

本発明の目的は、積層された第１フィルム及び第２フィルムを容易に引き剥がすことができ、引き剥がした第１フィルム及び第２フィルムの何れの側部も、被貼付体に確実に貼り付けることができる積層ラベルを提供することである。   The object of the present invention is to easily peel off the laminated first film and second film, and securely attach any side portion of the peeled first film and second film to the adherend. It is to provide a laminated label that can be used.

本発明の積層ラベルは、第１フィルムの一面に、前記第１フィルムの一方向に延びる剥離層と粘着層が、前記第１フィルムの他方向に交互に設けられており、第２フィルムの一面に、前記第２フィルムの一方向に延びる剥離層と粘着層が、前記第２フィルムの他方向に交互に設けられており、前記第１フィルムの剥離層が前記第２フィルムの粘着層に対面し、且つ前記第１フィルムの粘着層が前記第２フィルムの剥離層に対面して、前記第１フィルムと第２フィルムが剥離可能に重ね合わされており、前記第１フィルムの一面の両側部に、前記第１フィルムの一方向に延びる感熱接着層が設けられ、前記第２フィルムの一面の両側部に、前記第２フィルムの一方向に延びる感熱接着層が設けられていることを特徴とする。   In the laminated label of the present invention, a release layer and an adhesive layer extending in one direction of the first film are alternately provided on one side of the first film in the other direction of the first film. In addition, release layers and adhesive layers extending in one direction of the second film are alternately provided in the other direction of the second film, and the release layer of the first film faces the adhesive layer of the second film. And the adhesive layer of the first film faces the release layer of the second film, and the first film and the second film are detachably overlapped on both sides of one surface of the first film. The heat-sensitive adhesive layer extending in one direction of the first film is provided, and the heat-sensitive adhesive layer extending in one direction of the second film is provided on both sides of one surface of the second film. .

上記積層ラベルは、剥離層と粘着層がそれぞれ対面して重ね合わされているので、第１フィルムと第２フィルムを容易に引き剥がすことができる。なお、感熱接着層は、室温では接着性を示さないので、第１フィルムの感熱接着層と第２フィルムの感熱接着層は、重ね合わられている状態では接着しておらず、第１フィルムと第２フィルムを容易に引き剥がすことができる。
引き剥がした第１フィルム及び第２フィルムの一面には、一方向に延びる複数本の粘着層が露出するので、該粘着層を介して、第１フィルム及び第２フィルムを被貼付体に貼り付けることができる。
本発明の積層ラベルは、第１フィルムの両側部及び第２フィルムの両側部に、それぞれ感熱接着層が設けられているので、感熱接着層を加熱することによって、該感熱接着層を介して、第１フィルム及び第２フィルムの側部を、被貼付体に確実に貼り付けることができる。 Since the release label and the adhesive layer face each other and overlap each other, the first and second films can be easily peeled off. In addition, since the heat-sensitive adhesive layer does not exhibit adhesiveness at room temperature, the heat-sensitive adhesive layer of the first film and the heat-sensitive adhesive layer of the second film are not bonded in a superposed state, and the first film and the first film are not bonded. Two films can be easily peeled off.
Since a plurality of adhesive layers extending in one direction are exposed on one surface of the peeled first film and second film, the first film and the second film are attached to the adherend through the adhesive layer. be able to.
Since the laminated label of the present invention is provided with a heat-sensitive adhesive layer on each of both sides of the first film and the second film, by heating the heat-sensitive adhesive layer, through the heat-sensitive adhesive layer, The side parts of the first film and the second film can be reliably attached to the adherend.

本発明の積層ラベルは、第１フィルムの両側部及び第２フィルムの両側部の何れも、被貼付体に確実に貼り付けることができる。従って、該第１フィルム及び第２フィルムは、縁部が不用意に捲れないタックラベルとして使用できる。   In the laminated label of the present invention, both the both side portions of the first film and the both side portions of the second film can be reliably attached to the adherend. Therefore, the first film and the second film can be used as a tack label in which the edge is not carelessly wound.

以下、本発明の実施形態について図面を参照しつつ説明する。
図１及び図２に於いて、１０は、２枚のフィルム１，２（第１フィルム１及び第２フィルム２）が、剥離層１５，２５と粘着層１６，２６を対面させて重ね合わされた積層ラベルを示す。
この第１フィルム１の両側部１ａ，１ｂ及び第２フィルム２の両側部２ａ，２ｂには、それぞれ感熱接着層１７，２７が設けられている。なお、本発明において、フィルムとは、一般にシートと呼ばれているものが含まれる。 Embodiments of the present invention will be described below with reference to the drawings.
1 and 2, reference numeral 10 denotes two films 1 and 2 (first film 1 and second film 2) that are overlapped with the release layers 15 and 25 facing the adhesive layers 16 and 26. A laminated label is shown.
Thermal adhesive layers 17 and 27 are provided on both side portions 1a and 1b of the first film 1 and both side portions 2a and 2b of the second film 2, respectively. In the present invention, the film includes what is generally called a sheet.

第１フィルム１及び第２フィルム２の材質は、特に限定されず、例えば、合成樹脂製フィルム、紙、合成紙、発泡樹脂製フィルム、金属蒸着フィルム、不織布、又は、積層体（例えば、合成樹脂製フィルムと紙の積層体など）などを例示できる。好ましくは、第１フィルム１及び第２フィルム２は、感熱接着層１７，２７の加熱温度で実質的に変形しない耐熱性を有するフィルムが用いられる。
上記合成樹脂製フィルムとしては、耐熱性に優れ且つ剛性も有することから、ポリエチレンテレフタレートフィルムなどのポリエステル系、ポリアミド系、ポリプロピレンなどのポリオレフィン系などの合成樹脂製フィルムを用いることが好ましく、特に、これらの二軸延伸フィルムを用いることがより好ましい。
また、第１フィルム１及び第２フィルム２は、透明または非透明の何れのフィルムでもよい。 The material of the 1st film 1 and the 2nd film 2 is not specifically limited, For example, a synthetic resin film, paper, synthetic paper, a foamed resin film, a metal vapor deposition film, a nonwoven fabric, or a laminated body (for example, synthetic resin) For example, a laminate of a film and paper). Preferably, the first film 1 and the second film 2 are heat-resistant films that do not substantially deform at the heating temperature of the heat-sensitive adhesive layers 17 and 27.
As the synthetic resin film, since it is excellent in heat resistance and has rigidity, it is preferable to use a synthetic resin film such as a polyester type such as a polyethylene terephthalate film, a polyamide type, or a polyolefin type such as polypropylene. It is more preferable to use the biaxially stretched film.
The first film 1 and the second film 2 may be either transparent or non-transparent films.

第１フィルム１及び第２フィルム２の厚みは、特に限定されない。例えば、第１フィルム１及び第２フィルム２として合成樹脂製フィルムが用いられる場合には、通常、厚み１０〜１００μｍ程度であり、好ましくは１５〜８０μｍ程度である。   The thickness of the 1st film 1 and the 2nd film 2 is not specifically limited. For example, when synthetic resin films are used as the first film 1 and the second film 2, the thickness is usually about 10 to 100 μm, preferably about 15 to 80 μm.

第１フィルム１及び第２フィルム２は、それぞれ粘着ラベルとして使用されるので、必要に応じて、商品名、絵柄などの所望の意匠印刷が施される（図示せず）。意匠印刷は、第１フィルム１及び第２フィルム２の何れの面に施してもよいが、好ましくは、意匠印刷は、第１フィルム１の一面１ｃとは反対側の面１ｄ及び第２フィルム２の一面２ｃとは反対側の面１ｄに施される。なお、第１フィルム１の一面１ｃ及び第２フィルム２の一面２ｃとは、剥離層１５，２５、粘着層１６，２６及び感熱接着層１７，２７が設けられる面である。第１フィルム１の一面１ｃ及び第２フィルム２の一面２ｃに印刷を施すと、該印刷の上に、剥離層１５，２５及び粘着層１６，２６を塗工しなければならないが、この場合、剥離層１５，２５及び粘着層１６，２６の付着が悪くなることがあるからである。   Since the 1st film 1 and the 2nd film 2 are each used as an adhesive label, desired design printing, such as a brand name and a design, is given as needed (not shown). The design printing may be performed on any surface of the first film 1 and the second film 2, but preferably the design printing is performed on the surface 1 d and the second film 2 on the side opposite to the one surface 1 c of the first film 1. Is applied to the surface 1d opposite to the one surface 2c. The one surface 1c of the first film 1 and the one surface 2c of the second film 2 are surfaces on which the release layers 15 and 25, the adhesive layers 16 and 26, and the heat-sensitive adhesive layers 17 and 27 are provided. When printing is performed on one surface 1c of the first film 1 and one surface 2c of the second film 2, the release layers 15 and 25 and the adhesive layers 16 and 26 must be applied on the print. In this case, This is because the adhesion of the release layers 15 and 25 and the adhesive layers 16 and 26 may deteriorate.

第１フィルム１及び第２フィルム２の形状は、特に限定されず、ラベル形状を考慮して適宜設定される。
もっとも、生産性が良いこと、及びロール状に巻いてラベラーに供給できることなどから、第１フィルム１及び第２フィルム２は、長尺状に形成されていることが好ましい。 The shape of the 1st film 1 and the 2nd film 2 is not specifically limited, A label shape is considered and set suitably.
But it is preferable that the 1st film 1 and the 2nd film 2 are formed in the elongate shape from productivity etc. and being able to wind in a roll shape and to supply to a labeler.

本実施形態では、第１フィルム１及び第２フィルム２は、その一方向Ｘが他方向Ｙに比して十分に長く形成された長方形状（つまり長尺状）に形成されている。ただし、前記一方向Ｘ及び他方向Ｙとは、フィルムの面内において互いに直交する方向をいう。   In the present embodiment, the first film 1 and the second film 2 are formed in a rectangular shape (that is, a long shape) in which one direction X is sufficiently longer than the other direction Y. However, the one direction X and the other direction Y refer to directions orthogonal to each other in the plane of the film.

第１フィルム１及び第２フィルム２の他方向Ｙ（本実施形態では短手方向）の長さは、同じ長さが好ましい。もっとも、後述するように、第１フィルム１又は第２フィルム２の何れか一方の他方向Ｙの長さが、少し短く形成されていてもよい。   The lengths in the other direction Y (short direction in the present embodiment) of the first film 1 and the second film 2 are preferably the same length. But the length of the other direction Y of any one of the 1st film 1 or the 2nd film 2 may be formed a little short so that it may mention later.

上記第１フィルム１の一面１ｃには、他方向両側部１ａ，１ｂにおいて所定幅を除いた中央領域に、帯状の剥離層１５と帯状の粘着層１６が交互に設けられている。なお、隣接する剥離層１５と粘着層１６は、接していてもよいし、０．５ｍｍ〜１ｍｍ程度の形成間隔を隔てて設けられていても良い。
該剥離層１５及び粘着層１６は、第１フィルム１の一方向Ｘ（本実施形態では長手方向）に平行に延び、第１フィルム１の他方向Ｙに１本ずつ交互に設けられている。該剥離層１５及び粘着層１６の幅及び形成間隔は、何れも同じであることが好ましい。剥離層１５及び粘着層１６の幅は、特に限定されないが、通常、２〜１０ｍｍ程度、好ましくは２〜７ｍｍ程度である。もっとも、剥離層１５及び粘着層１６の幅及び形成間隔は、同一に限られず、異なっていてもよい。例えば、剥離層１５の幅が、粘着層１６の幅より幅広く形成されていてもよい。第１フィルム１の剥離層１５を幅広に形成する場合、これに対面する第２フィルム２の粘着層２６の幅は、前記剥離層１５の幅よりも狭く形成される。第１フィルム１及び第２フィルム２を容易に層間剥離するためである。
さらに、第１フィルム１の一面１ｃの他方向両側部１ａ，１ｂには、帯状の感熱接着層１７，１７が設けられている。該感熱接着層１７の一縁は、前記両側部１ａ，１ｂの縁に略一致している。感熱接着層１７は、第１フィルム１の一方向Ｘに平行に延びて設けられている。該感熱接着層１７の幅は、特に限定されないが、通常、２〜１０ｍｍ程度、好ましくは２〜７ｍｍ程度である。 On one surface 1c of the first film 1, strip-shaped release layers 15 and strip-shaped adhesive layers 16 are alternately provided in the central region excluding a predetermined width in both side portions 1a and 1b in the other direction. In addition, the adjacent peeling layer 15 and the adhesion layer 16 may be in contact, and may be provided at a formation interval of about 0.5 mm to 1 mm.
The release layer 15 and the adhesive layer 16 extend in parallel to one direction X (longitudinal direction in the present embodiment) of the first film 1 and are alternately provided one by one in the other direction Y of the first film 1. It is preferable that the width and the formation interval of the release layer 15 and the adhesive layer 16 are the same. The widths of the release layer 15 and the adhesive layer 16 are not particularly limited, but are usually about 2 to 10 mm, preferably about 2 to 7 mm. But the width | variety and formation space | interval of the peeling layer 15 and the adhesion layer 16 are not restricted to the same, You may differ. For example, the width of the release layer 15 may be formed wider than the width of the adhesive layer 16. When the release layer 15 of the first film 1 is formed wide, the width of the adhesive layer 26 of the second film 2 facing this is formed narrower than the width of the release layer 15. This is because the first film 1 and the second film 2 are easily delaminated.
Furthermore, belt-like heat-sensitive adhesive layers 17 and 17 are provided on both sides 1a and 1b in the other direction 1c of the first surface 1c of the first film 1. One edge of the heat-sensitive adhesive layer 17 substantially coincides with the edges of the side portions 1a and 1b. The heat-sensitive adhesive layer 17 is provided so as to extend in parallel with one direction X of the first film 1. The width of the heat-sensitive adhesive layer 17 is not particularly limited, but is usually about 2 to 10 mm, preferably about 2 to 7 mm.

上記第２フィルム２の一面２ｃには、他方向両側部２ａ，２ｂにおいて所定幅を除いた中央領域に、帯状の粘着層２６と帯状の剥離層２５が交互に設けられている。なお、隣接する剥離層２５と粘着層２６は、接していてもよいし、０．５ｍｍ〜１ｍｍ程度の形成間隔を隔てて設けられていても良い。
該剥離層２５及び粘着層２６は、第２フィルム２の一方向Ｘ（本実施形態では長手方向）に平行に延び、第２フィルム２の他方向Ｙに１本ずつ交互に設けられている。該剥離層２５及び粘着層２６の幅及び形成間隔は、上記第１フィルム１の剥離層１５及び粘着層１６の幅及び形成間隔と同じに形成されている。
さらに、第２フィルム２の一面２ｃの他方向両側部２ａ，２ｂには、帯状の感熱接着層２７，２７が設けられている。該感熱接着層２７の一縁は、前記両側部２ａ，２ｂの縁に略一致している。感熱接着層２７は、第２フィルム２の一方向Ｘに平行に延びて設けられている。該感熱接着層２７の幅は、特に限定されないが、本実施形態の場合には、上記第１フィルム１の感熱接着層１７と同幅に形成されていることが好ましい。 On the one surface 2c of the second film 2, strip-like adhesive layers 26 and strip-like release layers 25 are alternately provided in the central region excluding the predetermined width in the opposite side portions 2a, 2b. In addition, the adjacent peeling layer 25 and the adhesion layer 26 may be in contact, and may be provided with a formation interval of about 0.5 mm to 1 mm.
The release layer 25 and the adhesive layer 26 extend in parallel to one direction X (longitudinal direction in the present embodiment) of the second film 2, and are alternately provided one by one in the other direction Y of the second film 2. The width and formation interval of the release layer 25 and the adhesive layer 26 are formed to be the same as the width and formation interval of the release layer 15 and the adhesive layer 16 of the first film 1.
Furthermore, belt-like heat-sensitive adhesive layers 27 and 27 are provided on both sides 2a and 2b in the other direction of the one surface 2c of the second film 2, respectively. One edge of the heat-sensitive adhesive layer 27 substantially coincides with the edges of the side portions 2a and 2b. The heat-sensitive adhesive layer 27 is provided so as to extend in parallel with the one direction X of the second film 2. The width of the heat-sensitive adhesive layer 27 is not particularly limited, but in the case of the present embodiment, it is preferably formed to have the same width as the heat-sensitive adhesive layer 17 of the first film 1.

本発明の積層ラベル１０は、上記第１フィルム１の剥離層１５の表面が第２フィルム２の粘着層２６の表面に対面し、第１フィルム１の粘着層１６の表面が第２フィルム２の剥離層２５の表面に対面し、第１フィルム１の一方の側部１ａの感熱接着層１７の表面が第２フィルム２の一方の側部２ａの感熱接着層２７の表面に対面し、第１フィルム１の他方の側部１ｂの感熱接着層１７の表面が第２フィルム２の他方の側部２ｂの感熱接着層２７の表面に対面するように、上記第１フィルム１と第２フィルム２が重ね合わされることによって構成されている。   In the laminated label 10 of the present invention, the surface of the release layer 15 of the first film 1 faces the surface of the adhesive layer 26 of the second film 2, and the surface of the adhesive layer 16 of the first film 1 is the surface of the second film 2. The surface of the heat-sensitive adhesive layer 17 on one side 1a of the first film 1 faces the surface of the heat-sensitive adhesive layer 27 on one side 2a of the second film 2 and faces the surface of the release layer 25. The first film 1 and the second film 2 are arranged such that the surface of the heat-sensitive adhesive layer 17 on the other side 1b of the film 1 faces the surface of the heat-sensitive adhesive layer 27 on the other side 2b of the second film 2. It is configured by overlapping.

上記第１フィルム１及び第２フィルム２の剥離層１５，２５は、第１フィルム１及び第２フィルム２の一面１ｃ，２ｃの所定範囲に剥離剤を塗工することによって形成できる。
剥離剤としては、粘着層１６，２６に対して擬似接着しうるものが用いられる（擬似接着とは、僅かな剥離力で層間剥離できる程度に弱く付着している状態をいう）。該剥離剤としては、例えば、シリコーンや超微粒子などを含む溶剤型又はエマルジョン型の樹脂溶液、電離放射線硬化型樹脂溶液、紫外線硬化型インキなどの印刷インキなどを例示できる。
剥離層１５，２５は、通常、厚み１〜５μｍ程度に形成される。 The release layers 15 and 25 of the first film 1 and the second film 2 can be formed by applying a release agent to a predetermined range of the first surfaces 1c and 2c of the first film 1 and the second film 2.
As the release agent, one that can be pseudo-adhered to the pressure-sensitive adhesive layers 16 and 26 is used (the pseudo-adhesion refers to a state in which the layers are weakly adhered to each other with a slight peeling force). Examples of the release agent include solvent-type or emulsion-type resin solutions containing silicone and ultrafine particles, ionizing radiation curable resin solutions, and printing inks such as ultraviolet curable inks.
The release layers 15 and 25 are usually formed to a thickness of about 1 to 5 μm.

上記第１フィルム１及び第２フィルム２の粘着層１６，２６は、第１フィルム１及び第２フィルム２の一面１ｃ，２ｃの所定範囲に感圧型粘着剤を塗工することによって形成できる。なお、感圧型粘着剤とは、弱い圧力下で瞬間的に接着力を生じるものが含まれる。
該感圧型粘着剤としては、例えば、アクリル系粘着剤、ゴム系粘着剤などを用いることができる。
粘着層１６，２６の厚みは、通常、５〜２０μｍ程度に形成される。 The pressure-sensitive adhesive layers 16 and 26 of the first film 1 and the second film 2 can be formed by applying a pressure-sensitive pressure-sensitive adhesive to a predetermined range of the first surfaces 1c and 2c of the first film 1 and the second film 2. The pressure-sensitive adhesive includes those that instantaneously generate an adhesive force under a weak pressure.
As the pressure-sensitive adhesive, for example, an acrylic adhesive, a rubber adhesive, or the like can be used.
The thickness of the adhesive layers 16 and 26 is usually formed to be about 5 to 20 μm.

なお、第１フィルム１及び第２フィルム２として、一面全体に感圧型粘着剤がベタ状に設けられているフィルムを使用する場合には、該感圧型粘着剤の表面の所定範囲に上記剥離剤を塗工することによって、剥離層１５，２５を形成することもできる。この場合、剥離剤を塗布しない範囲には、感圧型粘着剤が露出するので、その範囲が、粘着層１６，２６となる。   In addition, when using the film by which the pressure sensitive adhesive was provided in the whole surface as the 1st film 1 and the 2nd film 2, the said release agent is used for the predetermined range of the surface of this pressure sensitive adhesive. The release layers 15 and 25 can also be formed by applying. In this case, since the pressure-sensitive adhesive is exposed in a range where the release agent is not applied, the range becomes the adhesive layers 16 and 26.

Examples of the delayed tack type heat-sensitive adhesive include an emulsion type in which a tackifier and a solid plasticizer are blended with a base resin such as an ethylene-vinyl acetate copolymer, a vinyl acetate-acrylic acid ester copolymer, and a synthetic rubber. The thing etc. are illustrated.
Emulsion-type heat-sensitive adhesives and solvent-type heat-sensitive adhesives do not show adhesiveness at room temperature, but show adhesiveness by heating. For example, heat-adhesive resins such as ethylene-vinyl acetate copolymer and tackifiers are water-soluble. Alternatively, it is an adhesive that can be applied by printing such as gravure coating, or a solution that is dissolved or dispersed in an organic solvent, and is an adhesive that is used after drying.
A hot-melt type heat-sensitive adhesive is an adhesive that does not exhibit adhesiveness at room temperature and can be bonded by heating, and can be applied by heating and melting. Examples of hot-melt type heat-sensitive adhesives include additives such as tackifiers to base resins such as ethylene-based resins such as ethylene-vinyl acetate copolymers and ethylene acrylic acid copolymers, and styrene-butadiene block copolymers. Are blended.
