PROBLEM TO BE SOLVED: To provide a film which is excellent in processability, heat resistance and transparency, does not deform after undergoing sterilization treatment, and maintains high transparency, and a medical container formed from the same.SOLUTION: Each of the film and the medical container is composed of a polyethylene resin composition obtained by blending 5 pts.wt. or more and less than 30 pts.wt. of an ethylene-α-olefin copolymer (A) and more than 70 pts.wt. and 95 pts.wt. or less of a high-pressure low-density polyethylene (B) having specific physical properties (total of (A) and (B) is 100 pts.wt.). The ethylene-α-olefin copolymer (A) satisfies that: it has a density of 920-950 kg/mand an MFR of 0.1-15 g/10 min it exhibits two peaks in molecular weight measurement by gel-permeation-chromatography it has a ratio (Mw/Mn) of a weight average molecular weight (Mw) to a number average molecular weight (Mn) in the range of 2.0-7.0 and it includes 0.15 or more of long-chain branch per 1000 carbon atoms of a main chain in a fraction having an Mn of 100,000 or more when molecular weight fractionation is carried out.SELECTED DRAWING: None【課題】 加工性、耐熱性、透明性に優れ、滅菌処理後も変形せず、高い透明性が保持されるフィルムを及びそれよりなる医療容器を提供する。【解決手段】 密度が920~950kg/m3、MFRが0.1~15g/10分、ゲル・パーミエーション・クロマトグラフィーによる分子量測定において2つのピークを示し、重量平均分子量(Mw)と数平均分子量(Mn)の比(Mw/Mn)が2.0~7.0の範囲であり、分子量分別した際のMnが10万以上のフラクション中に長鎖分岐を主鎖1000炭素数あたり0.15個以上有するエチレン-α-オレフィン共重合体を5重量部以上30重量部未満に、特定の物性を有する高圧法低密度ポリエチレンを70重量部を超えて95重量部以下((A)と(B)の合計は100重量部)配合したポリエチレン樹脂組成物よりなるフィルム及び医療容器を製造する。【選択図】 なし
