Abstract
Disclosed is a resin composition that comprises a propylene-based copolymer (X) consisting of two kinds of copolymeric components made up of propylene, &agr;-olefin and optionally ethylene which are characterized by ethylene content an &agr;-olefin content, the copolymer (X) exhibiting a specific endothermic behavior in DSC measurement and a copolymer (Y) made up of propylene and &agr;-olefin and/or ethylene. The resin composition can afford a film superior in low-temperature heat sealability and antiblocking property.
