ACTIVATED FILMS HAVING LOW SOUND PRESSURE LEVELS

摘要

A film comprising from about 20 wt.% to about 85 wt.% of a polyolefin component and from about 20 wt.% to about 45 wt.% of a particle component; wherein the film has a basis weight of from about 5gsm to about 25gsm; wherein the film is activated and subjected to an engineering strain of greater than about 20%; wherein the film has a predicted sound pressure level over the frequency octave range of 2000Hz - 6300Hz of less than about 43dB.
