<p>Biodegradable films permeable to moisture vapor and air which act as barriers to liquid are made by a high speed method. The films have high moisture vapor transmission rates (MVTRs) on the order of about 1000 to about 4500 g/m2/day according to ASTM E96E and air breathability of about 30 to about 2000 cc/cm2/min at 90 psi air pressure.</p> |
