Abstract
A film for use in an absorbent article is provided. The film is formed from a polymer composition that contains an ethylene polymer and a nanofiller. The present inventors have discovered that through selective control over the particular type and concentration of these components, as well as the manner in which it is formed, the resulting film may generate a relatively low degree of noise when physically deformed.
Claims27
A film having a thickness of from about 0.5 to about 80 micrometers, wherein the film is formed from a polymer composition that includes one or more ethylene polymers in an amount of from about 75 wt. % to about 99 wt. % of the polymer composition and one or more nanofillers in an amount of from about 0.5 wt. % to about 20 wt. % of the polymer composition, wherein the film exhibits a normalized noise level of about 2.5 or less as determined at a frequency of 4,000 Hz, wherein the normalized noise level is determined by dividing the noise level of the film by the noise level of an ambient environment.
