Abstract:
The present invention provides a plastic container that has excellent storage stability with respect to a pharmaceutical component having a high affinity to plastic, and that can be mass-produced at low cost. This plastic container has: a bag body (11) formed into a bag shape by a sheet member (12) and having a storage part (13) on the inside thereof; and a tubular port member (15) that is attached to the bag body (11), wherein one end of the tubular port member (15) communicates with the storage part (13), and an opening section (16) of the other end (15b) is exposed outside of the bag body (11). The sheet member (12) comprises two or more layers including a base resin layer (12b) and an innermost layer (12a). The innermost layer (12a) is formed by polymerizing at least one type or two or more types of olefin monomers, wherein at least one of the types of olefin monomers is composed of, as a main component, an amorphous polymer which is a monomer having a cyclic hydrocarbon skeleton. The port member (15) is formed from a resin having, as a main component, a crystalline polyolefin that does not have a cyclic hydrocarbon skeleton.
