Beschreibung
Zusammenfassung:	A film comprising from about 20 wt.% to about 85 wt.% of a polyolefin component, from about 5 wt.% to about 30 wt.% of an elastomeric resin, 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 has a predicted sound pressure level over the frequency octave range of 2000Hz - 6300Hz of less than about 43dB. 本发明公开了种膜，该膜包含约20重量％至约85重量％的聚烯烃组分、约5重量％至约30重量％的弹性体树脂、以及约20重量％至约45重量％的颗粒组分；其中该膜具有约5gsm至约25gsm的基重；其中该膜在2000Hz-6300Hz的频率倍频程范围上具有小于约43dB的预测声压水平。
