NOVELTY - A molded article is obtained using propylene-type resin composition containing propylene ethylene and/or alpha -olefin block copolymer (X) and propylene-ethylene block copolymer (Y). The copolymer (X) contains propylene homopolymer component and propylene ethylene and/or alpha -olefin copolymer component of propylene, and ethylene and/or 4-12C alpha -olefin. The copolymer (Y) contains propylene ethylene random copolymer component (A) having ethylene content of 7 wt.% or less, and propylene ethylene random copolymer component (B) containing more ethylene amount.    USE - Molded article e.g. food container, drink container, cap, medical container, medical device, motor vehicle component, electrical/electronic device component, industrial material and building material (all claimed). Uses include but are not limited to retort container, cosmetic container, test tube, diagnosis kit, semiconductor conveyance container, solar cell sealing material, film, fiber, optical component, dental material component, etc.    ADVANTAGE - The molded article has excellent rigidity, impact resistance and whitening-proof property, and is easily manufactured.    DETAILED DESCRIPTION - A molded article is obtained using propylene-type resin composition containing (in wt.%) propylene ethylene and/or alpha -olefin block copolymer (X) (40-99) and propylene-ethylene block copolymer (Y) (1-60). The copolymer (X) contains propylene homopolymer component (95-50) and propylene ethylene and/or alpha -olefin copolymer component of propylene, and ethylene and/or 4-12C alpha -olefin. The copolymer (Y) contains propylene ethylene random copolymer component (A) (30-95) having ethylene content of 7 wt.% or less, and propylene ethylene random copolymer component (B) (70-5) containing more ethylene amount than component (A) by 3-20 wt.%, and has melt flow rate of 0.5-100 g/10 minutes at 230 degrees C and load of 2.16 kg, melting peak temperature of 110-150 degrees C measured by differential scanning calorimetry, and molecular weight distribution of 1.5-4 by gel permeation chromatography. The tan- delta curve of copolymer (Y) exhibits single peak at 0 degrees C or less in temperature-loss tangent curve by solid viscoelastic measurement.
