Abstract:
1. A polyethylene composition comprising, a polyethylene base resin, which comprises: a. an ethylene copolymer as fraction (A), and b. an ethylene homo- or copolymer as fraction (B), with fraction (A) having a lower molecular weight than fraction (B), wherein the polyethylene base resin is obtained by a polymerization process in which a single-site catalyst (SSC) is used in the polymerization of at least one of fractions (A) and (B), and the polyethylene base resin has: wherein the polyethylene composition has a flexural modulus of from 400 to 820 MPa; wherein the polyethylene composition has a shear thinning index (SHI wherein a loop reactor, used in the polymerization process, is operated at a temperature of between 70 to 90° C.
