Abstract:
A garment having at least a first portion and a second end portion, the first portion having an extensible elastic tab having a fastening element on a distal end with an opposing distal end attached to the garment first portion and with the garment second portion having a complimentary fastening element, the disposable garment tab comprising a coextruded extensible elastic film comprising at least one elastic layer and at least one second layer on at least a first face of the elastic layer, the coextruded elastic film is attached to at least a partially extensible nonwoven layer on at least one face the partially extensible nonwoven layer having a first direction and a second direction the partially extensible nonwoven layer having at least one first portion being extensible in the first direction to an extension limit and at least one second inextensible portion in the first direction, wherein the coextruded elastic and the nonwoven layer when stretched to the extension limit of the nonwoven layer first portion(s) in the first direction will elastically recover at least 1.0 cm providing an elastic tab having a Useful Stretch Ratio (USR) of at least 30 percent, wherein the USR defined as the ratio of the useful range of elasticity to the initial extension length of the first portion at the upper extension limit, wherein the useful range of elasticity includes the portion of the elastic recovery length having an elastic recovery force of greater than 20 grams/cm force up to the upper extension limit where the upper extension limit is where the disposable garment tab has an incremental extension force of about 300 grams/cm to 350 grams/cm.
