PROBLEM TO BE SOLVED: To provide a propylenic polymer for sealant films, and provide a sealant film. SOLUTION: This propylenic polymer satisfies all of requirements consisting of [1] an MFR (230°C, 2.16 kgf) of 1 to 50 (g/10 min), [2] a decane-soluble content of≤3 wt.%, and [3] a melting point of≤120°C determined by DSC. The sealant film comprising the propylenic polymer and having aΔhaze (the change rate of haze after seven days at 80°C) of≤2%, heat seal strength of≥5 N/15 mm and a thickness of 1 to 100μm.
