<p>PROBLEM TO BE SOLVED: To provide a medical tool suitably usable as a high-unit and long-term platelet storage vessel excellent in oxygen permeability, compared with a conventional one, and having a blocking strength between sheets (bag inner surfaces) resistant to actual use. SOLUTION: This medical tool is formed of a composition of (1) 80-85% by mass of polyethylene obtained by copolymerizing ethylene with a<3-12> Cα- olefin by use of a metallocene catalyst and having a density of 0.860-0.900 g/cm<3> and a maximum melting peak temperature by differential scanning calorimetry(DSC) of 90 deg.C or lower; and (b) 15-20% by mass of a styrene- ethylene-butylene-styrene copolymer.</p> |
