In one embodiment, the present invention is directed to an article, such
as a blow-molded bottle, formed from a polymer blend composition. In one
aspect, the article is formed by blow-molding techniques. In one aspect,
the article is a blow-molded container having a Bruceton Mean Drop Height
of 3.8 feet or above. In another aspect, the article is a blow-molded
container having a volume of 60 fluid ounces or greater. In general, the
polymer blend composition comprises polypropylene and an impact modifier
of metallocene-produced very low density polyethylene or linear low
density polyethylene. In one embodiment, the polypropylene polymer
comprises a random copolymer. In one embodiment the metallocene-catalyzed
linear very low density polyethylene polymer has one or more of the
following: (a) a density of less than 0.916 g/cm.sup.3, (b) a composition
distribution breadth index of 50 to 85% by weight, (c) a molecular weight
distribution Mw/Mn of 2.0 to 3.0, (d) a molecular weight distribution
Mz/Mw of less than 2.0, and (e) two peaks in a TREF measurement. In one
embodiment, the polymer blend composition comprises 5% to 85% of the
impact modifier and 95% to 15% of the polypropylene polymer, based on the
total combined weight of the polypropylene polymer and the impact
modifier. In another embodiment, the polymer blend composition comprises
5% to 35% of the impact modifier and 95% to 65% of the polypropylene
polymer, based on the total combined weight of the polypropylene polymer
and the impact modifier.
