PROBLEM TO BE SOLVED: To provide a method for stably storing an ester-containing article without losing an aroma of the ester or decreasing lamination strength. SOLUTION: The method for storing an ester-containing article comprises sealing an ester-containing article by using a multilayered material comprising, from the outer surface side, at least a substrate layer, an adhesive resin layer, a PET layer, an adhesive resin layer and a sealant layer. The method is characterized in that: the adhesive resin layer is formed by curing an adhesive essentially comprising an epoxy resin having at least two epoxy groups in one molecule and an amine-based curing agent; the amine-based curing agent is a reaction product of metaxylylene diamine and a dicarboxylic acid component; at least 70 mol% of the dicarboxylic acid component comprises aliphatic dicarboxylic acids having 18 to 36 carbon atoms; and the adhesive resin shows elongation at break (conforming to JISK-7161 under the conditions of 10 mm width, 30μm thickness and 10 mm/min tensile speed) of 100 to 700%.
