| 摘要 |
The present invention provides a propylene resin composition (A) containing a combination of a component (a) a propylene homopolymer or propylene block copolymer having a propylene-chain isotactic pentad fraction of 0.90 or more; a component (b) an ethylene-alpha-olefin copolymer rubber, in an amount of 0.5 to 20 mass % when the component (a) is a propylene homopolymer, or in an amount of 0 to 10 mass % when the component (a) is a propylene block copolymer; a component (c) a high-density polyethylene, in an amount of 0 to 20 mass %; and a component (d) an inorganic nucleating agent, in an amount of 0.4 to 3.0 parts by mass on the basis of 100 parts by mass of the total amount of the components (a), (b), and (c), which composition exhibits high rigidity within a high-temperature range of room temperature or higher, which exhibits excellent impact resistance within a low-temperature range of the freezing point or lower, which emits odor at such a low level that it can be employed for food products, and which minimizes specific weight. The present invention also provides a multi-layer structure including at least one layer formed of the composition; a container produced through heat molding; an injection-molded product; an extrusion-molded product; and a method for producing such a molded product.
