<P>PROBLEM TO BE SOLVED: To provide an infusion bag capable of maintaining an oxygen barrier property even if a severe handling and a severe retort packaging are performed. <P>SOLUTION: The infusion bag 10 is formed by using a laminated body including a substrate and a gas barrier layer. The gas barrier layer includes a composition containng a hydrolytic condensate of at least one compound (L) containing a characteristic group having hydrolytic property and a polymer (X) containing carboxyl group and/or carboxylic anhydride group. At least a part of -COO- group of the polymer (X) is neutralized and/or reacted with a compound (P) containing two or more amino groups. At least a part of -COO- group of the polymer (X) is neutralized with divalent or multivalent metal ions. The ratio of [the equivalent weight of amino group contained in the compound (P)] to [the equivalent weight of -COO- group of the polymer (X)] is within the range of 0.2/100 to 20.0/100. <P>COPYRIGHT: (C)2010,JPO&INPIT |
