Abstract: A blow molded plastic container includes a multilayer sidewall having at least three consecutive layers A, B and C. Layers A and C are of identical plastic composition, and of a composition different from layer B. In exemplary embodiments of the disclosure: (1) layers A and C are of a composition selected from the group consisting of cyclic olefin polymers, cyclic olefin copolymers, acrylonitriles and blends thereof, and the layer B is of a composition selected from the group consisting of cyclic olefin polymers, cyclic olefin copolymers, polycarbonates and blends thereof; (2) layers A and C are of a composition selected from the group consisting of polycarbonates acrylonitriles and blends thereof, while layer B is of a composition selected from the group consisting of nylons, polycarbonate and blends thereof; and (3) layers A and C are of acrylonitrile composition, and layer B is of ethylene vinyl alcohol composition.
