Abstract
A film having low pressure values is provided. The film may have from about 20 wt. % to about 75 wt. % of a polyolefin component, from about 5 wt. % to about 35 wt. % of an elastomeric resin, and from about 20 wt. % to about 45 wt. % of a particle component. The film may have a basis weight of from about 5 gsm to about 25 gsm. The film may have a predicted sound pressure level over the frequency octave range of 2000 Hz-6300 Hz of less than about 43 dB.
