본 발명은 (A) 비-엘라스토머 폴리에틸렌 60 내지 90 wt%; (B) 에틸렌과 4 내지 12개의 탄소 원자를 갖는 알파-올레핀 공단량체 단위의 공중합체인 에틸렌계 엘라스토머 9.0 내지 38wt%; 를 포함하며, 여기서 성분 (A) 또는 성분 (A)와 (B) 상에 산 그래프팅제(C)가 모두 접착성 폴리에틸렌 조성물의 총 중량을 기준으로 0.01 내지 3.0wt%의 양으로 그래프팅되어 있는, 접착성 폴리에틸렌 조성물, 접착성 폴리에틸렌 조성물을 포함하는 다층 구조물 및 다층 구조물의 제조를 위한 접착성 폴리에틸렌 조성물의 용도에 관한 것이다. The present invention relates to an adhesive polyethylene composition comprising (A) from 60 to 90 wt % of a non-elastomeric polyethylene; (B) from 9.0 to 38 wt % of an ethylene based elastomer being a copolymer of ethylene and alpha-olefin comonomer units having from 4 to 12 carbon atoms; wherein onto component (A) or components (A) and (B) an acid grafting agent (C) has been grafted in an amount of from 0.01 to 3.0 wt %, all based on the total weight of the adhesive polyethylene composition, a multi-layer structure comprising said adhesive polyethylene composition and the use of said adhesive polyethylene composition for the production of a multi-layer structure.
