Abstract
Thermoplastic film, microporous film, and laminates thereof, are made at high speeds on the order of about 500 fpm to about 1200 fpm. Bond strengths of film and nonwoven laminates are effectively controlled by air cooling devices which cause the air to flow substantially parallel to the extruded web during drawdown and provide a plurality of cooling air vortices to effectively cool the web. Film gauge control is also achieved by the method.
