摘要： 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),log .tau..ltoreq.n log .gamma.+5.15 (1)andlog.tau..gtoreq.n log .gamma.+4.95 (2)wherein,.tau. is a shearing stress (dynes/cm.sup.2) as measured using a capillary rheometer in accordance with a flow property testing method (JIS K 7199), .gamma. is a shearing rate (sec.sup.-1) as measured by the same method, n is a number of from 0.39 to 0.41, and .gamma. lies from 9.times.10.sup.1 to 1.2.times.10.sup.3 sec.sup.-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.

摘要： A plastic container made of olefin resins having frosted appearance which gives excellent shade-off, deep and high-grade impression, and a process for producing the same. The process produces a plastic container having the above-mentioned appearance maintaining good reproducibility and excellent moldability. That is, a frosted plastic container wherein at least the outer surface of the plastic container is formed of a blend of plural kinds of olefin resins, one resin (A) forming the layer of said blend exists as a continuous phase, another resin (B) exists as a disperse phase, and the disperse phase which has an aspect ratio (ratio of long diameter/short diameter) of 6 or smaller and in which the grains exist having grain sizes (short diameters) of from 0.3 to 20 .mu.m, has an area percentage of at least 15% or larger relative to the whole sectional area.
