Abstract

La presente invencion proporciona un trama laminada, perforada, macroscopicamente expandida, tridimensional, adecuada para utilizarse como una hoja superior en un artículo absorbente y un método para hacer la misma. La trama incluye una primera capa de material polimérico, sustancialmente transparente, que tiene una superficie interna y una superficie externa. Una trama no tejida se asegura a la superficie interna del material polimérico, sustancialmente transparente. La presencia de la trama no tejida crea la apariencia de una trama fibrosa que es percibida con suave y amigable a la piel, mientras que aun mantiene los beneficios de transporte de fluido de las tramas plásticas del arte previo.
