<p>A blow-molded multi-layer plastic container having excellent surface luster which is obtained by blow-molding, as an outer surface of the container, an olefin resin which has fluidity properties satisfying the following formulas (1) and (2), <MATH> and <MATH> wherein, tau is a shearing stress (dynes/cm<2>) as measured using a capillary rheometer in accordance with a flow property testing method (JIS K 7199), gamma /<.> is a shearing rate (sec<-><1>) as measured by the same method, n is a number of from 0.39 to 0.41, and gamma /<.> lies from 9 x 10<1> to 1.2 x 10<3> sec<-><1>. The blow-molded multi-layer plastic container does not develop sharkskin or flow marks. Moreover, melt-treatment of the outer surface of the blow-molded article eliminates rugged pattern that stems from the sand-blasted surfaces of the metal mold. <IMAGE></p> |
