Summary:The present invention relates to improvements in or relating to linear low density polyethylenes (LLDPEs), in particular to the use of LLDPEs for injection moulding and to products obtainable thereby. An LLDPE produced using a single site catalyst, e.g., an LLDPE produced using a metallocene (m-LLDPE), is preferably used 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/dm, e.g., less than 5 mg/dm, and are particularly suitable for use in packaging foods having a high fat content.
