Zusammenfassung:	FILM LAYERS MADE FROM FORMULATED ETHYLENE POLYMER COMPOSITIONS ARE DISCLOSED. FILM LAYERS MADE FROM SUCH FORMULATED COMPOSITIONS HAVE SURPRISINGLY GOOD HEAT SEAL PROPERTIES, AND AN ESPECIALLY GOOD REDUCTION IN HEAT SEAL INITIATION TEMPERATURE. THE ETHYLENE POLYMER COMPOSITIONS HAVE AT LEAST ONE HOMOGENEOUSLY BRANCHED ETHYLENE/ALPHA-OLEFIN INTERPOLYMER AND AT LEAST ONE HOMOGENEOUSLY OR HETEROGENEOUSLY BRANCHED ETHYLENE POLYMER WHICH HAS A LOWER MELT INDEX THAN THE FIRST MENTIONED COMPONENT. THE FIRST HOMOGENEOUSLY BRANCHED ETHYLENE/ALPHA-OLEFIN INTERPOLYMER HAS A MELT INDEX HIGHER THAN THAT OF THE FORMULATED COMPOSITION.
