1. A method of manufacturing an elastic film laminate, the method comprising, sequentially:
initially stretching an elastic film in at least one direction at a first draw ratio;
relaxing the elastic film so that the elastic film is under a tension in a machine direction suitable to carry and support the elastic film in the machine direction;
subsequently stretching the elastic film at least once more in the at least one direction at a second draw ratio less than the first draw ratio to a stretched state; and
laminating the elastic film, while in the stretched state, to at least one substrate web after the initial stretching and also following the subsequent stretching at the second draw ratio,
wherein the first draw ratio is 4:1, and
wherein the second draw ratio is 3.1:1.
