An elastic assembly for absorbent garments having a first carrier layer, a second carrier layer, and an elastic layer attached between the first and second carrier layers to impart elasticity to an elasticized portion of the elastic assembly. The elastic layer is made of elastic strands having a decitex of about 600 or less. The elastic strands are arranged generally in parallel with one another and with a spacing of about 1 to about 10 elastic strands per centimeter. The elasticized portion of the elastic assembly has a thickness of about 2.6 mm or less at a pressure of 0.05 p.s.i. and about 8 or more corrugations per centimeter when in an elastically relaxed state. The first and second carrier layers are attached to one another in the elasticized portion substantially only by a coating of adhesive on the elastic strands. Absorbent garments incorporating the elastic assembly and a method of making the elastic assembly are also provided.

A diaper is provided which includes a chassis having front, rear, and crotch portions. The chassis includes a topsheet, backsheet, core and pair of ears. Each ear includes a topsheet, backsheet and proximal, distal, first connecting, and second connecting edges. The first connecting and second connecting edges connect the distal to proximal edges. The proximal edge is integral to the chassis. Each ear has an elastic layer sandwiched between its topsheet and backsheet. Each elastic layer has first and second edges which are secured to the ear topsheet and backsheet. The elastic layer has a central portion not secured to either the ear topsheet or backsheet. Each ear topsheet and backsheet has perforations. The tearable portion is adjacent to the central portion. Each ear may be pulled away from the chassis causing the ear topsheet and backsheet to tear at the perforations thereby exposing the elastic layer.

A disposable absorbent article is provided which includes a chassis having a front portion, a rear portion, a crotch portion, a topsheet, a backsheet, an absorbent core, and a pair of ear portions integral to the backsheet. Each ear portion has proximal, distal, first connecting and second connecting edges. The first and second connecting edges connect the distal to the proximal edges. The proximal edge is integral to the topsheet. Each ear portion has an elastic layer having first and second edges where the first edge and second edge are secured to the backsheet. The elastic layer has a central portion not secured to the backsheet. The ear portion has a tearable portion extending from the first to the second connecting edges and extends along the central portion of the elastic layer. A fastener joined to each of the elastic layers secures the disposable absorbent article.
