Abstract

Un artículo absorbente de la presente invención puede comprender un lienzo superior, una cubierta exterior y un núcleo absorbente dispuesto entre éstos. La cubierta exterior puede comprender una pieza laminada unida por extrusión. La EBL puede comprender una película elastomérica coextrudida multicapa y una tela no tejida. La película puede comprender una capa del núcleo, una primera capa exterior y una segunda capa exterior, en donde la capa del núcleo se encuentra entre la primera y la segunda capa exterior. La tela no tejida puede comprender fibras y/o filamentos. La primera capa exterior puede no estar unida adhesivamente a la tela no tejida por medio de un recubrimiento por extrusión. Además, la cubierta exterior puede ser elástica hasta por lo menos aproximadamente 50 % de deformación ingenieril. La tela no tejida puede tener una afinidad química alta por la primera capa exterior. La primera capa exterior puede tener una afinidad química baja por la capa del núcleo; y la película elastomérica coextrudida multicapa puede tener un peso base no mayor que aproximadamente 40 gm2.
