PROBLEM TO BE SOLVED: To provide a packaging laminated material adapted to a packaging container of which the wall thickness is reduced, showing good gas barrier properties though the amount to be used of a material is reduced and capable of suppressing the accumulation of a permeated oxygen gas or the like in a beverage housed in the container. SOLUTION: This packaging laminated material includes a support layer, a heat-sealable inner layer, a gas barrier resin layer, which comprises an ethylene/vinyl alcohol copolymer, a polyester resin, a nylon resin or a m-xylenediamine/adipic acid condensation polymer, provided to the inside of the support layer and an endothermic material triggered by moisture contained in the gas barrier resin layer or in the vicinity thereof to start endothermic reaction.
