Abstract:
A flavor-retaining plastic multi-layer container comprising, inner and outer layers of a non-cyclic olefin resin, and an intermediate layer of a cyclic olefin copolymer adhered together via adhesive resin layers, wherein said adhesive resin is a linear very-low-density polyethylene having a density of from 0.800 to 0.910 g/cm.sup.3 obtained by the copolymerization of an ethylene with an .alpha.-olefin of an amount of from 6 to 20 mol % per the adhesive resin, or is an acid-modified product thereof, wherein the cyclic olefin copolymer has a glass transition point (Tg) of not lower than 60.degree. C., and the non-cyclic olefin resin forming the inner and outer layers is a low-density polyethylene having a melt index (ASTM D1238, 190.degree. C.) of not larger than 2 g/10 min., and a logarithmic value of melt viscosity (220.degree. C.) of not smaller than 4.7 of when a logarithmic value of shearing rate is extrapolated to zero.
