Abstract of the Disclosure A bag for storage of platelets made of a resin comprising a polymer alloy consisting essentially of (a) 25 to 60 % by weight of poly(ethylene-butylene)- polystyrene block copolymer, (b) 20 to 40 % by weight of polypropylene, and (c) 5 to 35 % by weight of ethylene- acrylic acid ester copolymer, the segment of the polystyrene in the molecular chains of the polymer (a) having at least 2 oriented portions and the molecular chains of the polymers (a), (b) and (c) being entangled to form a network structure, and 1 to 20 % by weight of plasticizer, and a multiple bag system comprising a donor bag, a transfer bag and tubes for connecting the donor bag with the transfer bag. Platelets having an unclassified shape do not generate during the platelets are stored in the bag. The bag is not deformed when being subjected to intense centrifugation to separate platelets from blood plasma in the bag.
