<p>An incrementally stretched non-embossed film having a high vapor transmision rate (MVTR) comprising a thermoplastic polymer containing a dispersed phase of particles selected from the group consisting of an inorganic filler and an organic material. These non-embossed film products are permeable to moisture vapor and act as barriers to liquid. The microporous products have high moisture vapor transmission rates (MVTRs) on the order of about 2000 to about 4500 gms/m2/day according to ASTM E96E.</p> |
