<p>A polyolefin material having improved fibrillation properties, allowing one to achieve higher yield in cigarette filters made from the fibrillated material, includes between about 70 % and about 99 % of at least one polypropylene homopolymer with a melt index of between about 1.2 to about 3.0 (measured according to ISO standard 1133 at 230°C, 2.16 kgf) and a density of about 0.905 g/cc, and between about 1 % and about 30 % of at least one low density polyethylene homopolymer with a melt index of between about 0.9 and 3.0 (measured according to ISO standard 1133 at 190°C, 2.16 kgf) and a density of about 0.921 g/cc.</p> |
