Disclosed is a packaging material, wherein a barrier layer, an adhesive layer and a sealant layer are laminated in this order, and the adhesive layer includes an acid-modified polyolefin resin that contains a (meth)acrylic acid ester component. The packaging material is preferably produced by forming on the barrier layer the adhesive layer including the acid-modified polyolefin resin that contains a (meth)acrylic acid ester component, and by subsequently laminating a molten sealant resin on the adhesive layer by extrusion lamination.
