PROBLEM TO BE SOLVED: To provide an adhesive composition which can obtain a strong adhesive strength between laminate base materials, can maintain the strong adhesive strength for a long period of time, is excellent in safety because of using an FDA-approved raw material, and can be preferably used as a food packaging material; and a packaging bag for retort pouch for food which does not cause delamination due to reduction of an adhesive strength over time, and can endure against long-term preservation, even when filling a content with a food and an oily food of high acidity.SOLUTION: A polybasic acid component is one or more compounds selected from the group consisting of isophthalic acid, orthophthalic acid, terephthalic acid, 2,6-naphthalene dicarboxylic acid, trimellitic acid, adipic acid, sebacic acid, fumaric acid, maleic acid, dimer acid and 1,4-cyclohexanedicarboxylic acid. An adhesive composition contains polyester polyol having 90 mol% or more of butanediol as a polyhydric alcohol component, and a polyisocyanate compound.SELECTED DRAWING: None |
