Patent ID: 8450426

Claim:
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: (i) a density of below 940 kg/m3, and (ii) a MFR2 at 190 20 C. / 2.16 kg of 0.01 to 10 g/10 min; wherein the polyethylene composition has a flexural modulus of from 400 to 820 MPa; wherein the polyethylene composition has a shear thinning index (SHI 2.7/2.10 ) below 20; and wherein a loop reactor, used in the polymerization process, is operated at a temperature of between 70 to 90° C.
