    Abstract: PROBLEM TO BE SOLVED: To provide a method for preserving an ester-containing article stably without releasing the aroma of the ester and lowering a lamination strength. SOLUTION: The method for preserving the ester-containing items seals the ester-containing article using a multilayer object made of at least metal foil or a metal vapor deposition layer, an adhesive resin layer, and a sealant layer. The adhesive resin layer is formed by curing an adhesive containing an epoxy resin having at least two epoxy groups in a molecule and an amine curing agent as main components. The amine curing agent is a product of the reaction between meta-xylylenediamine and a dicarboxylic acid component, and at least 70 mol% of the dicarboxylic acid component is a 18-36C aliphatic dicarboxylic acid. The elongation at break of the adhesive resin (based on JISK-7161, width 10 mm, thickness 30 μm, and tensile speed 10 mm/min) is 100-700%. COPYRIGHT: (C)2011,JPO&INPIT
