Abstract: The present invention provides and a plastic container and multilayered films, which comprises a heat-sealable seal layer, a cyclic polyolefin layer, and an outermost layer, wherein the seal layer comprises polypropylene, the cyclic polyolefin layer comprises a cyclic polyolefin polymer or a cyclic polyolefin copolymer, and the outermost layer comprises a layer containing polypropylene, and which further comprises a resin composition layer comprises a blended product of a propylene polymer and a styrene elastomer. The plastic container of the present invention can suppresses a reduction in the medicament content of a liquid-state medicament and is excellent in terms of shock resistance, handling ability during the filling of the container with the medicament, and the moldability and transparency of the container.
