본 발명은 플라스틱과 친화성이 높은 의약품 성분에 대해 우수한 보존안정성을 갖고, 낮은 비용으로 대량 생산이 가능한 플라스틱 용기를 제공한다. 시트 부재(12)에 의해 백 형상으로 형성되고 내부에 수용부(13)를 갖는 백 본체(11)와, 백 본체(11)에 장착된 수용부(13)에 일단(15a)이 연통하고, 타단(15b)의 개구부(16)가 백 본체(11)에 의해 외측에 노출된 통 형상의 포트 부재(15)를 갖는 플라스틱 용기로서, 시트 부재(12)는 베이스 수지층(12b)과 최내층(12a)을 포함하는 2층 이상으로 이루어지고, 최내층(12a)은 적어도 1종류 또는 2종류 이상의 올레핀 모노머를 중합하여 이루어지며, 당해 올레핀 모노머 중 적어도 1종류는 고리형 탄화수소 골격을 갖는 모노머인 비정성 폴리머가 주성분으로 이루어지고, 또한 포트 부재(15)는 고리형 탄화수소 골격을 갖지 않는 결정성 폴리올레핀을 주성분으로 하는 수지에 의해 형성되어 있다. The present invention provides a plastic container which has superior storage stability with respect to a pharmaceutical ingredient exhibiting a high affinity to plastic, and which can be mass-produced at low cost. The plastic container has a bag body (11) which is formed into a bag shape by a sheet member (12) and has a storage part (13) on the inside thereof; and a tubular port member (15) attached to the bag body (11), in which one end (15a) of the tubuar port member communicates with the storage part (13) and an opening part (16) of the other end (15b) is exposed outside of the bag body (11). The sheet member (12) is formed from two or more layers including a base resin layer (12b) and an innermost layer (12a), and the innermost layer (12a) is formed from an amorphous polymer, as a main component, formed by polymerizing at least one type or two or more types of olefin monomers, in which at least one type of the olefin monomers is a monomer having a cyclic hydrocarbon skeleton, and the port member (15) is formed from a resin having a crystalline polyolefin having no cyclic hydrocarbon skeleton, as a main component.
