본 개시내용은 통기성 필름 및 이것의 제조 방법을 제공한다. 본 개시내용에 따른 통기성 필름은, (1) 총 CEF 분율의 80% 이상의, 70℃에서 90℃까지의 CEF 분율; (2) ASTM D 1238(2.16 kg @190℃)에 따라 측정하여 2.0 g/10 min 이상 5.0 g/10 min 이하 범위의 용융 지수, I; 및 (3) 6.7 이하의 용융 흐름 비, I/I의 각각을 나타내는 60 중량% 이하의 선형 저밀도 폴리에틸렌 수지를 포함하는 폴리머성 조성물을 포함하는 필름 층을 포함한다. The present disclosure provides breathable films and method of making the same. The breathable films according to the present disclosure comprise a film layer comprising polymeric composition comprising equal to or less than 60 wt% of a linear low density polyethylene resin which exhibits each of the following properties: (1) a CEF fraction from 70 to 90 °C of equal to or greater than 80% of the total CEF fractions; (2) a melt index, I 2 , measured according to ASTM D 1238 (2.16 kg @ 190°C), in the range of equal to or greater than 2.0 g/10 min and equal to or less than 5.0 g/10 min; and (3) a melt flow ratio, I 10 /I 2 , of equal to or less than 6.7.
