摘要： The invention provides the use in the manufacture of a polyethylene article of a polyethylene composition comprising 20 to 50 % wt of a copolymer of ethylene and a C3-20 alpha olefin comonomer and 50 to 80 % wt of a lower weight average molecular weight ethylene polymer, the polyethylenes of said composition together having a density of 935 to 965 kg /m3, a weight average molecular weight of 60000 to 300000 g/mol, an MFR2.16 at 190°C of 0.1 to 10 g/10 min., and a molecular weight distribution (MWD) of from 2.5 to 20, said copolymer having a comonomer content of from 0.006 to 9 mol % and a degree of branching of 0.03 to 45 branches per 1000 carbons, and said ethylene polymer having a density of 939 to 975 kg/m3 and a weight average molecular weight of 20000 to 200000 g/mol.

摘要： The invention relates to the use of an LLDPE produced using a single site catalyst, e.g. an LLDPE produced using a metallocene (m-LLDPE), in injection moulding of food packaging material, especially closures for food containers. Such materials have been found to exhibit low levels of migration, typically less than 40 mg/dm2, e.g. less than 5 mg/dm2, and are particularly suitable for use in packaging foods having a high fat content.
