Title:
高圧蒸気滅菌可能で薬液を保存する医療用容器
Document Type and Number:
Japanese Patent JP4101465
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a medical container having an excellent balance of physical properties among heat resistance, flexibility, transparency, low-temperature impact resistance, flexing fatigue resistance, heat sealability and the like and excellent workability at the molding and capable of steam-sterilizing at a high pressure. SOLUTION: A container body is formed of a linear low-density polyethylene or an ethylene α-olefin copolymer and constituted of a laminate of an inner layer and an outer layer. The outer layer is polymerized by using a metallocene catalyst and having a density of 0.920 to 0.930 g/cm3. The inner layer is formed of a polymer composition containing (A) the copolymer polymerized by using a metallocene catalyst and having a density of 0.89 to 0.920 g/cm3, (B) the copolymer polymerized by using the metallocene catalyst and having a density of 0.920 to 0.930 g/cm3 and (C) the copolymer polymerized by using a Ziegler- Natta catalyst and having a density of 0.910 to 0.930 g/cm3. In this case, a ratio of a thickness occupied by the inner layer with respect to that of the entire laminate is made from 65 to 85%.
