<p>PROBLEM TO BE SOLVED: To provide a liquid medicine case which has sufficient heat distortion resistance and transparency even in the high pressure steam sterilization at 120 deg.C or higher degrees. SOLUTION: This liquid medicine case is made of a resin and consists of transparent and soft walls in laminated structure. In the liquid medicine case in which a liquid medicine treated with high pressure steam sterilization is stored, the innermost layer of the walls is made of a mixed resin (hereinafter called PE-PP) of polyethylene (hereinafter called L-PE) whose density is below 0.940 g/cm3 and polypropylene (hereinafter called PP), and the weight mixture ratio of PE to PP in the PE-PP layer is in the range from 50/50 to 95/5.</p> |
