An absorbent article comprising: a liquid permeable layer; a liquid-impermeable layer that contains a film; and an absorbent core positioned between the liquid permeable layer and the liquid-impermeable layer; the film having a thickness of from about 0.5 to about 80 micrometers, wherein the film is formed from a polymer composition comprising one or more ethylene polymers in an amount of 95 wt. % to about 99 wt. % of a total polymer content of the polymer composition, wherein the one or more ethylene polymers comprises a linear low-density polyethylene in an amount of from 75 wt. % to about 99 wt. % of the polymer composition, a polyolefin compatibilizer in an amount of from 0.5 wt. % to about 5 wt. % of the total polymer content of the polymer composition, and one or more nanofibers in an amount of from about 0.5 wt. % to about 20 wt. % of the polymer composition, wherein the nanofiller includes carbon black, carbon nanotubes, carbon nanofibers, nanoclays, metal particles, silica, alumina, or a combination thereof, wherein the film exhibits a noise level of about 45 decibels or less as determined at a frequency of 4,000 Hz, and wherein the film exhibits a peak elongation in the machine direction of 400% or more.
