Abstract
A thin nanocomposite film for use in an absorbent article (e.g., sanitary napkin) is provided. The film contains a first ethylene polymer having a density of about 0.94 g/cm3 or less, second ethylene polymer having a density of greater than 0.94 g/cm3, and nanoclay having an organic surface treatment. The present inventors have discovered that through selective control over the particular type and concentration of the components used to form the film, as well as the manner in which it is formed, the properties of the film can be significantly improved.
