(57) [Abstract] [Problem] A good balance between rigidity and heat sealability. Provided are a film having excellent blocking resistance and a small amount of solvent-soluble components, a metal vapor-deposited film having excellent vapor-deposition strength, and a propylene random copolymer from which these can be obtained. SOLUTION: It is composed of propylene and an α-olefin other than propylene, the melting point Tm and the flexural modulus FM satisfy a specific relationship, and the following formula (where [OO], [PP], [OP] represents the molar fraction of two consecutive monomer units), and a propylene random copolymer characterized by a CSD value of 3.5 or less is used. CSD = 4 [OO] × [PP] / [OP] 2 |
