Abstract
A package that contains a wrapper material that defines an interior cavity within which an absorbent article is removably positioned is provided. The wrapper material is formed from a film that includes a polymer composition containing at least one ethylene polymer and at least one 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 package may generate a relatively low degree of noise when physically deformed.
Claims20
A package comprising a wrapper material that defines an interior cavity and an absorbent article removably positioned within the cavity, wherein the wrapper material is formed from a film having a thickness of from about 0.5 to about 80 micrometers, wherein the film contains 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, and wherein the package exhibits a normalized noise level of about 3.0 or less as determined at a frequency of 4,000 Hz, the normalized noise level being determined by dividing the noise level of the package by the noise level of an ambient environment.
