ばれている。When using a porous base material such as paper or woven fabric as a support for the adhesive tape or sheet, a laminate material such as polyethylene is usually provided as a sealing layer on at least one side of the base material, and if necessary, Release agent layers are laminated accordingly. In this case, in order to obtain good unwinding properties even when wound into a roll, the adhesive strength for 180 degree peeling on the back surface specified in JIS Z 0237 must be 20 g.
The adhesive and release agent are selected so that f/10 is less than true.
この種の粘着テープ又はシートは、ロール状に捲回して

がある。Although this type of adhesive tape or sheet has excellent unwinding properties even when wound into a roll, there is a problem in that it cannot be laminated.

は基材の層間強度以上に大きくなるためである。However, when the main component of the adhesive layer of this type of adhesive tape or sheet is acrylic ester, it has excellent unwinding properties even when wound into a roll.
The reality is that the laminate material peels off from the base material, or the base material breaks between layers, and the adhesives that are mainly composed of natural and/or synthetic rubber do not fulfill the function of the tape or sheet. . This is because adhesives whose main component is acrylic ester have difficulty adhering to laminate materials such as polyethylene and can be rewound even without a release agent layer, whereas natural This is because an adhesive mainly composed of synthetic rubber is soft, highly fluid, and has a large adhesive area, so that the unwinding force becomes greater than the adhesive strength of the laminate material or the interlaminar strength of the base material.
さらに、アクリル酸エステルを主成分とする粘着剤は、

An adhesive tape or sheet with a structure in which molding agents are laminated in a certain order and an adhesive layer is provided on the other side is rolled in 11! It was discovered that it has good unwinding properties even if it is rotated, and that it can be pasted in layers, leading to the present invention.

い。The laminate material (aluminum material) used in carrying out the present invention
The materials for the laminate material Cbl are usually polyalkylenes such as polyethylene and polypropylene, and copolymers of the polyalkylenes and monomers copolymerizable with the polyalkylenes (
For example, ethylene-vinyl acetate copolymer, ethylene-vinyl acetate copolymer,
Examples include thermoplastic polymers such as acrylic acid copolymers (acrylic acid copolymers, etc.). However, laminate material (as Al, AST

One type or a mixture of several crl-grooved polymers can be used. On the other hand, the laminate material To) has the M+
is 15 dg/min or less, preferably 13 dg/min or less, more preferably 11 dg/min or less, and the density is 0.93
g/ct of polymers greater than or equal to 1, preferably 0.
One type of polymer or a mixture of several types of polymers having a weight ratio of 935 g/c- or higher is used. Note that the laminate material used in the present invention may contain pigments, stabilizers, fillers,
It may contain a lubricant, a crosslinking agent, an antiblocking agent, etc.

になるため均一な離型剤層を設けることが困難になる。In the adhesive tape or sheet of the present invention, each layer must be laminated in the order of base material-laminate material (al-laminate Murayama). If this order is reversed,
The adhesion between the base material and the laminate material deteriorates, making it impossible to obtain good unwinding properties, and the surface of the laminate material becomes uneven, making it difficult to provide a uniform release agent layer.

180 degree peeling adhesive force to the back of the tape or sheet specified in 237 is 20gf/10w or more,
300gf/l or less, preferably 40gf/10
It is preferable to use a combination that is higher than or equal to 200gf/10 days.If the adhesive strength is less than 20gf/10m, sufficient stackability cannot be obtained. If it is too large, the porous base material will break between the eyebrows when the tape or sheet wound into a roll is rewound, making it impossible to obtain good unwinding properties, which is not preferable. A specific example of the above combination is:
Examples include the following: In the case of adhesives whose main component is natural and/or synthetic rubber, long-chain alkyl compounds such as polyvinyl octadecyl carbamate systems, polyethyleneimine octadecyl carbamate systems, phenyl-modified systems, and silicones. A mold release agent selected from silicone compounds such as those containing resin is combined.

That is, the laminate material fal, which has an MI of more than 15 dg/min and a density of less than 0.93 g/cd, has high fluidity and therefore firmly adheres to the porous base material. In addition, a laminate material whose Ml is 15 dg/min or less and a density of 0.93 g/cm3 or more (bl is
Since it is highly heat resistant and the surface is less likely to become uneven, a uniform release agent layer can be provided.
