CAPUCHONES AND CLOSURES.

摘要

A process for preparing caps and closures of carbonated beverages with a bimodal high density polyethylene resin (HDPE) produced with a catalyst system comprising a bisindenyl based catalyst component and wherein said HDPE resin has a density, measured following the procedure ASTM 1505 standard at a temperature of 23 ° C, from 0.945 to 0.965 g / cm3, a MI2 melt index, measured following the standard test procedure of ASTM D 1238 at a temperature of 190 ° C and under a load of 2.16 kg, from 1 to 10 dg / min, and a molecular weight distribution, defined by the polydispersion index D which is the ratio Mw / Mn between the weighted average molecular weight Mw and the numerical average molecular weight Mn, of at least 3.
