Breathable film is produced by using cast film technology and they are gravured by the chillroll technology. Breathable films has barrier characteristics; and can withstand water column resistance starting from 100 cm h20 . Even though it does propose a liquid barrier since it has water resistance; breathable films can tranmist water water vapor 200 gr. WVTR 24 h/1m2 (200 gr. water vapor permeability 24 hours 1/m2) . Thus, it creates the breathable structure.
