が良好なものは得られにくい。 Conventionally, there is a method as shown in FIG. 1 as a method for joining films having heat-adhesive properties. As shown in FIG. 1, the film 2 to be bonded is placed between an ultrasonic horn 1 and a lower pedestal 3, and pressure is applied while applying ultrasonic waves to the horn to thermally fuse the film 2. In such a method, it is known that if the lower cradle or horn is made uneven, complete fusion can be achieved with a small amount of energy, but in the conventional method as shown in Figure 1, Even if a flat horn was used, as shown in FIG. 2, a step of several tens of microns would occur due to the unevenness of the lower pedestal, and the smoothness of the joint surface would be poor. but,
If both the horn and the lower pedestal are flat, thermal distortion is likely to occur on the joint surfaces, making it difficult to obtain a smooth joint surface.

The present invention provides an ultrasonic bonding method for films, which is characterized by improved smoothness of the bonded surface.

合面の平滑性が向上していることがわかる。 Hereinafter, the present invention will be explained in detail with reference to the drawings. FIG. 3 shows an embodiment of the bonding method of the present invention, in which heat-adhesive films 2 are stacked one on top of the other, and a buffer layer with an adhesive layer is formed between a bottom pedestal 3 having an uneven surface and an adhesive layer. 4 is provided, and the flat horn 1 is fused by applying pressure while applying ultrasonic waves. In this case, the buffer layer 4 fixes the films 2 to each other, thereby preventing the films from moving and shifting due to ultrasonic vibrations during adhesion, thereby enabling highly accurate fusion bonding. It also acts as a cushion between the lower pedestal 3 and the film 2, and prevents the unevenness of the lower pedestal from appearing on the joint surface. The thickness of the buffer layer (including the adhesive layer) is 100 to 200% of the thickness of the film, and the height of the unevenness of the lower pedestal is the thickness of the overlapping part of the film (the thickness of two films and the buffer layer). 20 to 60% of the total thickness (plus the thickness of Note that the heat-fusible film 2 may be a multilayer film. A cross section of the bonded surface obtained by the method of the present invention is shown in FIG. 4, and it can be seen that the smoothness of the bonded surface is improved.
