POLYPROPYLENE BLOWN FILM.

摘要

Disclosed is a blown film or sheet material comprising a broad molecular weight distribution propylene polymer material having a molecular weight distribution Mw/Mn of about 40 to about 60, a melt flow rate of about 0.5 to about 50 dg/min, and xylene insolubles at 25 degree C of greater than or equal to 94 percent. A mixture of the broad molecular weight distribution propylene polymer material and a heterophasic olefin polymer composition can also be used.
