<p>PROBLEM TO BE SOLVED: To provide a laminate for a battery packaging, reduced in deterioration in laminate strength and generation of interlayer separation between an aluminum foil and an innermost layer due to deterioration in an electrolyte of a lithium ion battery and further capable of manufacturing a packaging container with high yield.SOLUTION: In a laminate for battery packaging comprising an aluminum foil and a resin layer laminated in order therein, a base material layer 11 comprising two layers of a polyethylene terephthalate (PET) film and a polyamide film layer, an aluminum foil 12, and an innermost layer 13 comprising a layer of polypropylene or polyethylene are laminated in order. On at least the innermost layer surface of the aluminum foil 12, a thin film coating layer 14 formed of a water soluble resin or a copolymer resin thereof is laminated, the thin film coating layer 14 being crosslinked or formed in amorphous to have water resistance.</p> |
