Abstract
An article of commerce includes a disposable cleaning article and a package. The package exhibits soft visual and sound characteristics. The package is formed as a multilayer packaging film including at least a co-extruded vapor barrier film layer and a polymeric film layer having a melting point at least about 20° C. less than the co-extruded film layer. The polymeric film layer is sealable to form the package so as to enclose the disposable cleaning article, thereby to substantially retain the water content of the disposable cleaning article. The polymeric film layer further exhibits a corrected sound level of less than approximately 50 decibels at readily audible frequencies, such as 3-5 kHz. The reduced sound level may be achieved by providing a film with a high loss tangent. In addition, the multilayer packaging film may have an outer surface with a soft or “matte” appearance.
