Propylene-based resin composition and film made of the same |
摘要 |
Disclosed is a resin composition that comprises a propylene-based copolymer (X) consisting of two kinds of copolymeric components made up of propylene, alpha-olefin and optionally ethylene which are characterized by ethylene content and alpha-olefin content, the copolymer (X) exhibiting a specific endothermic behavior in DSC measurement; a crystalline olefin-based polymer (Z) having a melting point up to 115° C.; and optionally a copolymer (Y) made up of propylene and alpha-olefin and/or ethylene. The resin composition can be modified by addition of a propylene-based polymer (W) and/or a nucleating agent (N) and can yield a film superior in low-temperature heat sealability and antiblocking property.
