Abstract: An absorbent article such as a diaper, pant diaper, a sanitary pant or incontinence garment has at least one first elastic web material which is ultrasonically welded to at least one second web material along at least one weld seam. The second web material is different to the first elastic web material and the second web material has a degree of elasticity which is different to the elasticity of the first elastic web material. The ultrasonic weld seam between the first elastic web material and the second web material is reinforced to have a weld strength in a direction transverse to the weld seam which is at least 5N/25.4 mm.

Abstract: An absorbent article such as a diaper, pant diaper, a sanitary pant or incontinence garment has at least one first elastic web material which is ultrasonically welded to at least one second web material along at least one weld seam. The second web material is different to the first elastic web material and said second web material has a degree of elasticity which is different to the elasticity of the first elastic web material. The ultrasonic weld seam between the first elastic web material and the second web material is reinforced to have a weld strength in a direction transverse to the weld seam which is at least 5 N/25.4 mm. The disclosure particularly relates to pant-type absorbent articles.

Abstract: A pant-type absorbent article having a core region (3) and a front (5) and a back panel (6) having an elastic web material (10) constituting the sole component of at least part of the front and/or back panels The article further has an elastic waistband (7) having at least one reinforcing elastic element (14a) extending substantially in parallel with a waist edge (22) of the chassis. In order to provide an increased fit and comfort in the waist area an area of a height (a) of at least 5 mm, as seen in the longitudinal (y) direction of the article, adjacent said waist edge (22) of the chassis, is free from reinforcing elastic element(s) (14a) along at least a substantial part of the circumference of said waist edge along which the elastic waistband (7) extends.
