Abstract

A method for manufacturing a breathable elastic laminate includes aperturing an elastic film to create an apertured elastic film with a pattern. The pattern includes a plurality of first lanes extending in a machine direction, each of the plurality of first lanes having a plurality of apertures, and a plurality of second lanes extending in the machine direction. Each of the plurality of second lanes is devoid of apertures and has a width of at least twice the width of one of the apertures in the first lanes. The plurality of second lanes alternate with the plurality of first lanes in a cross direction substantially orthogonal to the machine direction. The method includes stretching the apertured elastic film in the machine direction to activate the apertured elastic film and bonding a first side of the activated apertured elastic film to a nonwoven web to create a breathable elastic laminate.
