A resin-molded article comprising (a) a polyolefinnresin and (b) a thermoplastic resin other than thenpolyolefin resin (a), has, in a thickness directionnvertical to the surface of the article, as morphologynobserved under an electron microscope in the article, anportion where the polyolefin resin (a) forms a continuousnphase (A), a portion where the resin (b) other than thenpolyolefin resin (a) forms the continuous phase and thenpolyolefin resin (a) forms a discontinuous phase (B), and anportion where the polyolefin resin (a) forms the continuousnphase (A), which are successively observed in order fromnthe surface toward the inside along the thicknessndirection, such molded articles having a nature such asntoughness and fabrication quality inherent in thenpolyolefin resins and improved appreciably in resistance tonpermeation of liquid chemicals and gases. |
