POLYMERIC FILMS AND METHODS TO MANUFACTURE THE SAME

摘要

In one aspect, the disclosure relates to multilayer polymeric films comprising: at least one layer A, and at least one layer B; wherein at least one of layers A and B further comprises at least one copolymer of propylene derived units and one or more C2, and C4 to C10 alpha-olefin derived units, the copolymer having: (a) a C2, and/or C4 to C10 alpha-olefin derived unit content in the range of about 5 to 30 weight %; (b) an intermolecular composition distribution of greater than or equal to 75%; (c) a Tm in the range of from about 25° C. to about 110° C.; (d) a Hf in the range of from about 0.5 to about 70 J/g; (e) a Mw/Mn in the range of from about 1.2 to about 4.5; and (f) a MFR in the range of from about 0.1 to about 40 g/10 min; and wherein the multilayer polymeric film has a seal strength greater than 6.25 N/cm, at a dwell time of 0.75 seconds.
