The present invention relates to a laminated film and a laminating method capable of obtaining various physical properties such as tear strength and pinhole resistance.

塗布していた。Recently, demands for various physical properties of films have become increasingly strict, and in order to meet these demands, a laminated film composed of two or more kinds of films is often used. As a laminating method, there is a method of co-extruding two or more kinds of resins in the presence or absence of an adhesive, but the already formed film is pasted with the adhesive, generally called dry lamination. There is a way. This method is a method in which an adhesive is applied to the entire adhesive surface of one film, and the other film is pressed from above and bonded. When applying the adhesive, for example, the adhesive was applied to the entire surface of one film by a roll having a mesh cell with a mesh of 140 mesh and a depth of about 75 μm.

剤を用いて好ましい接着強度を有する積層フィルムを得
る技術が求められていた。Since the conventional dry laminating method applies an adhesive to the entire surface, the air permeability is lost when, for example, a nonwoven fabric and a film provided with a large number of minute holes for imparting air permeability are laminated. Therefore, there has been a demand for a technique of laminating each film while keeping the air permeability. Further, since a large amount of the adhesive is consumed, the cost of the adhesive in the product is high, and there has been a demand for a technique for obtaining a laminated film having a preferable adhesive strength by using a small amount of the adhesive.

する。An object of the present invention is to solve the above-mentioned problems, and the constitution is such that in a laminated film in which two or more kinds of films are bonded by an adhesive, the adhesive is applied in the form of fine dots, The adhesive agent is pressed and spreads, and there are fine adhesive spots or mesh-like portions where the adhesive agent is not applied.

The film to be laminated is not limited to a single layer film, but can be applied to already laminated films, and the method of the present invention can be repeated twice or more to obtain a film having three or more layers. The adhesive is not particularly limited as long as it can bond them.

強度が低下する。The method of applying the adhesive is preferably a roll having fine dents (cells) on the entire surface as used in an intaglio printing machine. The cell is filled with the adhesive when the roll is dipped in the adhesive layer. Then, the doctor blade or the like is used to remove the adhesive from the area other than the cells, and the image is transferred to a film. The cell diameter is
It is 0.05 to 1 mm, preferably 0.1 to 0.5 mm. Cell diameter is 1
If it exceeds mm, unevenness occurs in the laminated film and the transparency is impaired. The area occupied by cells on the roll surface is 1/2 to 1/5
It is 0, preferably about 1/6 to 1/20. If it is 1/2 or more, the adhesive spreads over the entire surface when the other film is attached, leaving no area where no adhesive is applied. However, even in such a case, it has an effect of halving the adhesive coating amount. If it is less than 1/50, the adhesive strength will decrease.

度を示す。In the case where the other film is laminated to the film in which the adhesive is applied in a dot shape in this way, the adhesive application area is expanded 3 to 4 times by the pressure at the time of attachment, and the amount of the adhesive used is conventionally. This is 1/5 to 1/20 of that of the technology, and shows the same adhesive strength as that of the bonding by the conventional technology, despite the fact that the non-adhesive application site remains.

There is. It was found that even with a smaller amount of adhesive applied as compared with the conventional method, it has sufficient adhesive strength if the sites applied with a sufficient thickness are uniformly dispersed. Furthermore, even if there is a portion where no adhesive is applied, if it is evenly and finely divided or has a fine mesh-like shape, it has been found that the adhesive strength is the same as before. did.
