Zusammenfassung:	Disclosed is a high-density polyethylene resin composition for a blown film, wherein the resin composition satisfies the wide width and high-speed processability and can be processed continuously. The present invention provides a high-density polyethylene resin composition for an inflation film, which comprises: 70-99 wt% of high-density polyethylene having a melt flow index (MFR) (190 ℃, load of 2.16 kg) of 0.01-1 g/10min and a density of 0.940-0.970 g/㎤; and 1-30 wt% of linear low density polyethylene prepared with a metallocene catalyst having a melt flow index (MFR) (190 ℃, load of 2.16 kg) of 0.5-1.9 g/10min and a density of 0.910-0.930 g/㎤. 블로운 필름용 고밀도 폴리에틸렌 수지 조성물로서 광폭 및 고속 가공성을 만족하고 연속적인 가공이 가능한 수지 조성물이 개시된다. 본 발명은 용융 흐름 지수(MFR)(190℃, 2.16 kg 하중)가 0.01 내지 1 g/10min 및 밀도가 0.940 내지 0.970 g/㎤인 고밀도 폴리에틸렌 70 내지 99 중량%; 및 용융 흐름 지수(MFR)(190℃, 2.16 kg 하중)가 0.5 내지 1.9 g/10min 및 밀도가 0.910 내지 0.930 g/㎤인 메탈로센 촉매로 제조된 선형 저밀도 폴리에틸렌 1 내지 30 중량%;를 포함하는 인플레이션 필름용 고밀도 폴리에틸렌 수지 조성물을 제공한다.
