Abstract
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.
