To provide a packaging material for blood bags, having high water vapor permeation resistance for suppressing permeation of water in an anticoagulant solution or a red cell storage solution which includes contents of a blood bag out of a packaging, and having excellent stability in water vapor permeation resistance and transparency under a high temperature and humidity environment for extend periods of time.
This packaging material for blood bags is characterized by comprising a laminate film (I) containing a base layer (Y), an inorganic vapor deposition layer (X) formed on top of the base layer (Y), a layer (Z1) including a polymer (a) of an unsaturated carboxylic acid compound polyvalent metal salt (A) formed on top of the inorganic vapor deposition layer (X), and a layer (Z2) including a polymer (a) of an unsaturated carboxylic acid compound polyvalent metal salt (A) and a vinyl alcohol based polymer (b) formed on top of the layer (Z1), laminating at least two laminate films (I) with the layers (Z2) on the inside to form a laminate film (II), and laminating a heat seal layer on top of either one of the base layers (Y) of the laminate film.
