  • Publication number: 20060009603
    Abstract: The present invention relates to fibrillation resistant polypropylene tape formed from the polymerization of propylene utilizing isospecific metallocene catalysts. The resulting polymerized isotactic polypropylene is heated, extruded and withdrawn as a film or sheet. The sheet is then slit longitudinally into tape segments and drawn in the longitudinal direction to a draw ratio of at least about 4.5:1 to produce an oriented tape. It has been found that these polypropylene tapes have improved resistance to fibrillation than those polypropylene tapes produced using Ziegler-Natta catalyst drawn at the same draw ratios.
