な製造方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roll-shaped adhesive tape and a method for manufacturing the same, and more specifically, a non-adhesive layer of the same thickness is substituted for a part of the adhesive layer. By using it as a adhesive, it is easy to peel off after adhesion, and when it is wound into a roll, the outer shape may be uneven.
The present invention relates to a roll-shaped adhesive tape that does not peel off and a suitable method for manufacturing the tape.

に均一の厚みの粘着剤層を塗布したセロハンテープ等の
粘着テープは、種々の分野で広範に利用されている。[Prior art and problems to be solved by the invention] Adhesive tapes such as cellophane tapes, which have an adhesive layer of uniform thickness applied to one or both sides of a base material layer such as paper, plastic film, or cloth, are used in various fields. Widely used.
この従来より用いられている粘着テープは、被貼付体の
特性に応じて基材や粘着剤を適宜選択することによって
、目的とする被貼付体と強固な接着性が発揮されるが、
被貼付体との易剥離性に難点があった。This conventionally used adhesive tape exhibits strong adhesion to the target object by appropriately selecting the base material and adhesive depending on the characteristics of the object.
There was a problem with ease of peeling from the object to which it was applied.

れて、被貼付体からの剥離が完全に行なわれない場合も
生じる。In other words, with conventional adhesive tapes, even if they are easy to adhere to the object to which they are applied and are strongly adhered,
It is difficult to peel off this adhesive tape; for example, you have to scratch the edge of the tape with your fingernail to create a gap, which is extremely inconvenient, and it is difficult to remove the gap if the gap is of a suitable size. Otherwise, part of the adhesive tape may be torn off during peeling, and the adhesive tape may not be completely peeled off from the object to which it is applied.
また、粘着テープの被貼付体からの剥離時に被貼付体を
損傷させることは多々あることである。Furthermore, when an adhesive tape is peeled off from an object, the object is often damaged.

このような粘着テープの被貼付体からの剥離時の課題を
解決する手段として、基材層の表面の一部に粘着剤層を
塗布しない部分を設け、被貼付体からの剥離時にこの部
分を扼み部として用いようという試みがなされている。As a means to solve such problems when peeling the adhesive tape from the object to which it is applied, a part of the surface of the base layer is provided with no adhesive layer, and this part is removed when the adhesive tape is peeled from the object to which it is applied. Attempts have been made to use it as a strainer.

しくないという新たな課題を生じる。However, since adhesive tapes are usually used in rolls, when such adhesive tapes are wound into rolls, there is a difference in thickness between the areas where the adhesive layer is applied and the areas where the adhesive layer is not applied. As shown in Figure 6 (a) and (b), the roll profile becomes uneven or loses its shape.
A new problem arises in that it cannot withstand practical use and is not desirable in terms of commercial value.

好適な製造方法を提供することを目的とする。The present invention has been made to solve these problems of the prior art, and has excellent peelability from the object to which it is applied, does not cause damage to the object, etc., and when wound into a roll. An object of the present invention is to provide a roll-shaped adhesive tape that does not lose its shape and a suitable manufacturing method thereof.
［課題を解決するための手段］
本発明の上記目的は次に示すロール状粘着テープにより
達成される。[Means for Solving the Problems] The above objects of the present invention are achieved by the following roll-shaped adhesive tape.

られる。この場合、粘着剤層３の厚みを均一にするため
には、ドクターブレード法の手法が好適に採用される。Further, the adhesive forming the adhesive layer 3 may be any adhesive as long as it can firmly adhere to the object 5 to be adhered to under pressure and can be peeled off, and is appropriately selected depending on the object 5 to be applied. For example, thermosetting resin adhesives such as silicone resins, thermoplastic resin adhesives such as polyvinyl alcohol, elastomer adhesives such as neorene, and natural resins such as casein, dextrin, gum arabic, or rosin are used. This adhesive layer 3 is applied to one side of the base material layer 2, and the single-sided adhesive tape 1
Alternatively, it may be applied to both sides of the base layer 2 to form a double-sided adhesive tape 1. In addition, in the case of forming the double-sided adhesive tape 1, it is necessary to further laminate a release paper. The method of applying the adhesive layer 3 to the base material layer 2 is the same as that of conventional adhesive tapes, and for example, means similar to ink application means in printing technology are adopted, and specifically, roll coating, brush coating, etc. One example is a coating method such as coating. In this case, in order to make the thickness of the adhesive layer 3 uniform, a doctor blade method is suitably employed.

工できることが必要である。The adhesive tape 1 of the present invention is provided with a non-adhesive layer 4 having the same thickness as a part of the adhesive layer 3, but the non-adhesive layer 4 does not substantially adhere to the object 5 to which it is applied. Although it is fine, it is necessary that it can be easily laminated on the base material layer 2 and that it can be applied to the same thickness as the adhesive layer 3.
このような観点からは、熱可塑性樹脂または熱硬化性樹

であることから望ましいが、特にこのことに限定される
ものではなく、上記した要件を満たすものであればいず
れでもよい。From this point of view, it is preferable to use a resin composition containing a thermoplastic resin or a thermosetting resin as a main component and soluble in water or a solvent, since these resin compositions can be printed on the base material layer 2. Although it is preferable for this reason, it is not particularly limited to this, and any material may be used as long as it satisfies the above requirements.
この基材層２へ非粘着剤層４を設ける方法も特に制限さ

手段と同様の手段が採用されるが、この非粘着剤層４は
粘着剤層３と常に実質的に同厚となることが必要である
。The method of providing the non-adhesive layer 4 on the base material layer 2 is not particularly limited, and for example, the same means as the ink application means in printing such as gravure printing can be adopted. It is necessary that the thickness is always substantially the same as No. 3.
この非粘着剤層４は、被貼付体５から剥離できるように
なっていれば、その形状は任意であり、例えば装飾模様
としてもよい。また、非粘着剤層４には、注意書きまた
は宣伝広告等の文字や記号を印刷してさらに実用的価値
を高めてもよい。This non-adhesive layer 4 may have any shape as long as it can be peeled off from the object 5 to which it is applied, and may have a decorative pattern, for example. Further, the non-adhesive layer 4 may be printed with characters or symbols such as cautionary notes or advertisements to further increase its practical value.
基材層２に、粘着剤層３と非粘着剤層４を塗布または形
成する順序は任意であり、同時に行なってもよい。The adhesive layer 3 and the non-adhesive layer 4 may be applied or formed on the base layer 2 in any order, and may be applied at the same time.

It is installed in the roll winding direction of the original fabric,
In this case, the desired dimensions of the final adhesive tape 1 (a+b)
After providing the adhesive layer 3 and the non-adhesive layer 4 with the same thickness on a double width (2(a+b)), the adhesive layer 3 and the non-adhesive layer 4 are wound. and/or along the middle of the non-adhesive layer 4 along the cut line 9. In the same figure, cut line 9
is provided on both the adhesive layer 3 and the non-adhesive layer 4, so that the adhesive tape 1 having the non-adhesive layer 4 on one side can be obtained. On the other hand, if the cut line 9 is provided only on the non-adhesive layer 4, an adhesive tape 1 having the non-adhesive layer 4 on both sides will be obtained, and if the cut line 9 is provided only on the adhesive layer 3, the inner side An adhesive tape 1 having a non-adhesive layer 4 is obtained.
［発明の効果コ
以上説明したように、本発明のロール状粘着テープは、
被貼付体から剥離する際に、非粘着剤層が扼みとなるた
め剥離が容易である。また、従来のように粘着テープを
ロール状にする際に、ロール外形が不均一となったり、
また形部れを起こしたりすることがない。[Effects of the Invention] As explained above, the rolled adhesive tape of the present invention has
When peeling off from the object to be applied, the non-adhesive layer acts as a drag, making it easy to peel off. In addition, when adhesive tape is rolled into rolls as in the past, the roll shape may become uneven, or
Also, it does not cause deformation.
従って、本発明のロール状粘着テープは、セロハンテー
プ、クラフトテープ、絆創膏等の広範な分野の種々の用
途に適用可能であり、特に剥離時に内部の食品等までが
変形または損傷するような恐れがある脆弱な包装材料の
封止に用いられる粘着テープとして好適である。Therefore, the roll-shaped adhesive tape of the present invention can be applied to a variety of applications in a wide range of fields, such as cellophane tape, craft tape, and bandages, especially when there is a risk that the food inside may be deformed or damaged when peeled off. It is suitable as an adhesive tape for sealing certain fragile packaging materials.
また、本発明の製造方法によって、得られる上記のロー
ル状粘着テープの断面は粘着剤層と非粘着剤層の干渉が
なく美麗な製品となり、またカット箇所の位置決めの微
調整も容易である。Moreover, the cross section of the roll-shaped adhesive tape obtained by the manufacturing method of the present invention is a beautiful product with no interference between the adhesive layer and the non-adhesive layer, and the positioning of the cut portion can be easily finely adjusted.
