| Zusammenfassung: | A flexible film article includes: a film body (1) having opposite first and second surfaces (11, 12), and at least one surrounding surface (13) extending from the first surface (11) to the second surface (12) and defining a through hole (14) extending through the film body (1); at least one central member (3) spaced apart from the surrounding surface (13); and a plurality of spaced-apart extending members (2), each of which having two opposite ends (21, 22) connected to the surrounding surface (13) and the central member (3), respectively. The spaced-apart extending members (2), the central member (3), and the surrounding surface (13) cooperatively define spaced-apart micropores (10) for passing of a gaseous substance therethrough. |
