<p>PURPOSE:To provide the bag for preserving blood components which has excellent gas permeability, has no danger of elution of a plasticizer into blood, is less deformed, has high strength and sufficiently withstands the long-term preservation of the blood and mechanical operations, such as centrifugal operation. CONSTITUTION:This bag for preserving the blood components is produced from a polymer mixture contg. the following (a), (b) and (c): (a) 25 to 70wt.% hydrogenated deriv. of a copolymer consisting of an independent polymer block of styrene and an elastomer type independent polymer block of isoprene; (b) 15 to 40wt.% copolymer consisting essentially of polypropylene or propylene; (c) 15 to 40wt.% ethylene/acrylic-ester copolymer.</p> |
