Abstract:
1. A packaging material for blood bags comprised of two laminate films (I), each laminate film (I) comprising a base layer, an inorganic deposited layer formed on top of the base layer, a layer containing a polymer of an unsaturated carboxylic acid compound polyvalent metal salt formed on top of the inorganic deposited layer, and a layer containing a polymer of an unsaturated carboxylic acid compound polyvalent metal salt and a vinyl alcohol based polymer formed on top of the layer containing a polymer of an unsaturated carboxylic acid compound polyvalent metal salt, wherein said two laminate films (I) are laminated by laminating the layers containing a polymer of an unsaturated carboxylic acid compound polyvalent metal salt and a vinyl alcohol based polymer to form a laminate film (II), and a heat seal layer is laminated on top of at least either one of the base layers of the laminate film (II).
