A pharmaceutical/medical container using the rubber molded article is also disclosed. A rubber molded article (10) for containers for extremely-low-temperature storage is obtained by laminating an elastomer-blended silicone rubber (3) and an elastomer-blended silicone or butyl rubber (2) through a polyethylene film (4) having a molecular weight of 1,000,000-7,000,000. A pharmaceutical/medical container comprises at least the rubber molded article (10) for containers for extremely-low-temperature storage and a container for extremely-low-temperature storage which is composed of a cyclic olefin polymer resin or a hydrogenated product thereof.</p> |
