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