A battery packaging material is formed of a laminate. The laminate is composed of an outer layer including a substrate layer, a barrier layer as an intermediate layer, and a heat fusible resin layer as an innermost layer. The total thickness of the laminate is 60 μm to 220 μm. The barrier layer is formed of a metal foil. The product of a stress value and a thickness of the heat fusible resin layer at a time of 10% stretching is 1,200 Pa.Math.m or more.

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.
