CAPS AND CLOSURES |
摘要 |
This disclosure relates to caps and closures manufactured from an ethylene interpolymer product, or a blend containing an ethylene interpolymer product, where the ethylene interpolymer product has: a Dilution Index (Yd) greater than 0; total catalytic metal ≧3.0 ppm; ≧0.03 terminal vinyl unsaturations per 100 carbon atoms, and; optionally a Dimensionless Modulus (Xd) greater than 0. The ethylene interpolymer products have a melt index from about 0.4 to about 20 dg/minute, a density from about 0.948 to about 0.968 g/cm3, a polydispersity (Mw/Mn) from about 2 to about 25 and a CDBI50 from about 54% to about 98%. Further, the ethylene interpolymer products are a blend of at least two ethylene interpolymers; where one ethylene interpolymer is produced with a single-site catalyst formulation and at least one ethylene interpolymer is produced with a heterogeneous catalyst formulation. |
