Abstract
A polyethylene composition comprising a base resin is disclosed herein. The base resin includes an ethylene homo- or copolymer fraction (A1), and an ethylene homo- or copolymer fraction (A2). Fraction (A1) has a lower weight average molecular weight than fraction (A2). The base resin has a melt flow rate MFRof equal to or less than 8.0 g/10 min and a density of 930 to 950 kg/m3. The polyethylene composition has a melt flow rate MFRof 0.01 to 0.3 g/10 min, a flow rate ratio FRRof equal to or more than 20 and a ratio of the weight average molecular weight and the number average molecular weight (M/M) of equal to or less than 30. Also the polyethylene composition has a tensile modulus of less than 1000 MPa. Also a process for the production of a polyethylene composition comprising polyethylene base resin is disclosed herein.
