Abstract:
A pant type absorbent article having a core region includes an absorbent core and a chassis region surrounding the core region. The article in at least a part of the chassis region includes a coversheet in the form of an elastic laminate constituting the sole component of the chassis in at least 20% of the total surface area of the article. The elastic laminate has a tensile strength of at least 15 N/25 mm both in the longitudinal and transverse directions of the article and a tensile strength in the transverse direction of the article which is no more than 2.5 times and preferably no more than 2 times higher than the tensile strength in the longitudinal direction of the article. The force required to extend the elastic laminate 10% in the longitudinal direction of the article is no more than 5 N/25 mm.
