Abstract
An absorbent article is described which may be formed at least in part of thermoplastic and other fibers. The article is densified along a first region and has a tear line defined in the first region. A second region of lower density than the first region is provided at the termination point of the tear line to assist in stopping tearing along the tear line. In addition, densified reinforcing regions can be provided outside areas where the tear line curves or switches directions. Perforations or cuts in the tear line may extend continuously around the corner of the tear line to assist tearing around the corner.
