Zusammenfassung:	Provided is an ethylene copolymer having improved hygienic property. More particularly, the ethylene copolymer satisfies a correlation between a density thereof and an extract content. The ethylene copolymer having improved hygienic property can be applied in injection molding, rotation molding, or blow molding. L'invention concerne un copolymère d'éthylène ayant une propriété hygiénique améliorée. Plus particulièrement, le copolymère d'éthylène satisfait une corrélation entre un poids spécifique de celui-ci et une teneur en extrait. Le copolymère d'éthylène ayant une propriété hygiénique améliorée peut être appliqué dans le moulage par injection, le moulage par rotation ou le moulage par extrusion-soufflage.
