Title:
PRESERVATION CONTAINER FOR BLOOD OR BLOOD COMPONENT
Document Type and Number:
Japanese Patent JP3233738
Kind Code:
B2
Abstract:
PURPOSE: To obtain a preservation container which is provided with the excellent preservability for blood platelet by using a multilayer sheet consisting of the innermost layer consisting of a block copolymer having a micro-phase separation structure and the layer consisting of the thermoplastic resin composition comprising a specific hydrogenated diene copolymer and a polyethylene resin as main components.
CONSTITUTION: A blood preservation container consists of a sheet having a multilayer structure, and the innermost layer of the sheet is formed from a block copolymer having a micro-phase separation structure. Further, at least one layer of other layers of the sheet is formed from a thermoplastic resin composition comprising 40-90wt.% specific hydrogenated diene copolymer and 60-10wt.% polyethylene resin as main components. As the specific hydrogenated diene copolymer, is listed a block copolymer which contains each ≥1 of polymer blocks A containing aromatic vinyl compound as a main component, conjugated diene polymer blocks B, and polybutadiene polymer blocks C, and consists of 3-30wt.% A, 40-80wt.% B, and 10-40wt.%. C.
