[Peeling Resistance] Evaluation was made based on the number of cases where the joints were peeled off during the mounting in 50 cases. [Ease of tearing] The welded portion was actually pulled by hand, and the method of applying force and the method of tearing were evaluated in the following four grades. :: Can be easily torn. :: tearing without applying great force, no material tear. Δ: A large force is required to tear, and the material may be broken. X: A very large force is required to tear, and the material is broken.

[Table 1] Thus, when the area of the welded portion is 50% or more, it is impossible to obtain a good texture. In addition, if the bonding strength of the bonding portion is less than 1000 gf / 30 mm, inadvertent peeling of the bonding portion may occur even during mounting, and if the bonding strength is more than 5000 gf / 30 mm, detachment of the pants-type disposable diaper. Even at times, it is difficult to peel off. And when the area of a welding part is less than 25-50%, the joining part of preferable 1000-5000 gf / 30mm of joining strength can be obtained.
