Patent ID: 8252861

Claim:
Film tapes comprising a blend of: (a) about 5 to about 35 wt % of a masterbatch comprising: (i) about 5 to about 95 wt % of a propylene-based elastomer, the wt % based upon total weight of the masterbatch, the propylene-based elastomer having: A. about 50 to about 99 mol % of units derived from propylene; B. about 1 to about 50 mol % of units derived from at least one C 2 -C 20 comonomer; and C. a peak melting point temperature, measured by differential scanning calorimetry, of 115° C. or less; and (ii) about 5 to about 95 wt % of a filler, the wt % based upon the total weight of the masterbatch; and (b) about 65 to about 95 wt % of a propylene homopolymer having a peak melting point temperature, measured by differential scanning calorimetry, of greater than 130° C. and a melt flow rate, measured according to ASTM D-1238 (230° C./2.16 kg), of 0.1 to 35 dg/min.
