Abstract

Disclosed is a film which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The film has first and second surfaces and defines least one microporous passageway allowing communication, through the film, between the first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the film via a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it and prohibiting its passage through the film.
