Abstract

La presente invencion se dirige a una película termoplástica (54), la cual tiene una primera superficie (59) y una segunda superficie (64). Esta segunda superficie (64) está espaciada de la primera superficie (59). Una pluralidad de perforaciones (52) se extienden a través de la película (54) desde la primera superficie hacia la segunda superficie (64). Las perforaciones (52) forman capilares (55), los cuales se extienden desde la segunda superficie (64). Estos capilares (55) se disponen en un ángulo de 5 a 60 grados, aproximadamente, con respecto a un plano, el cual es perpendicular a la primera superficie (59).
