摘要：: Breathable films formed from polyethylene are provided that can have desirable properties. In one aspect, a breathable film comprises a layer formed from a composition comprising a first composition, wherein the first composition comprises at least one ethylene-based polymer and wherein the first composition comprises a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2 7.0-1.2 x log (I2).本發明係提供可具有所欲性質之自聚乙烯形成的透氣薄膜。在一方面中，透氣薄膜包含一自一含第一組成物之組成物形成的層體，其中該第一組成物包含至少一以乙烯為主的聚合物，且其中該第一組成物包含一大於0.9之MWCDI值、及一符合以下方程式：I10/I27.0-1.2×log(I2)之熔化指數比(I10/I2)。
