摘要：
Laminates are described that contain a frangible layer adhered to at least one extensible layer, such as an elastic layer. In one embodiment, a frangible layer is positioned between two opposing elastic layers. The frangible layer includes lines of separation that generally extend in a first direction. The lines of separation allow the elastic layers to stretch and recover in a direction perpendicular or skew to the lines of separation. In one particular embodiment, the lines of separation comprise lines where the frangible layer has been weakened. The lines of separation can be formed after the laminate is made using groove rolls.
