Abstract
An elastic composite includes a first nonwoven, a second nonwoven, and two elastic films sandwiched between the first and second nonwoven. The elastic composite also includes a lateral edge portion where the first nonwoven is bonded to the second nonwoven, a lane between the elastic films that is free of the elastic films, and a first bond joining the first nonwoven to the elastic film, and a second bond joining the second nonwoven to the elastic film. The elastic composite may be used as a component of a disposable garment.
