Abstract
As Metallocene Catalysed Polyethylenes (mPEs) become more commercially available they are finding ever increasing application in the blown film industry. However, it is becoming apparent that no two mPE resins behave in exactly the same manner. This paper examines the Theological properties of a range of mPEs with different densities and MFIs. These resins were then blended with a conventional low density polyethylene (LDPE) and extruded to form monolayer films. The mechanical properties of these films were compared to three layer coextruded films of A:B:A structure, where A is LDPE and B is mPE.
