The present invention pertains to a hexahedral laminate that: is provided with at least a first layer and a second layer that deforms more under pressure than the first layer; and has a top surface, a bottom surface, and four side surfaces, at least one of which consists only of the aforementioned first layer. The present invention makes it possible, even if a laminate comprising a layer that deforms less under pressure and a layer that deforms more under pressure is for example stored stacked for a long period of time, to: inhibit or prevent the layer that deforms more under pressure from protruding out from the sides of the laminate; and inhibit or prevent laminates from fusing together or adhering to a packaging container.
