Document Type and Number:
Japanese Patent JP7160225
Kind Code:
B2
Abstract:
An exterior material for power storage devices which is formed from at least a layered body comprising a base material layer, a barrier layer, and a heat-fusible resin layer in this order, wherein the base material layer contains a resin film, the resin film has a shrinkage ratio of 1.0% to less than 5.0% when immersed in hot water at 95°C for 30 minutes, and the resin film has a stress value, at 10% stretching in the tensile test described hereafter, of 100 MPa or higher in both the machine direction and the transverse direction.(Tensile test)After storing a sample in a 23°C, 40% RH environment for 24 hours, the tensile test is performed under conditions of a sample width of 6 mm, a gauge length of 35 mm, and a tension rate of 300 mm/min in a 23°C, 40% RH environment, and the stress value at 10% stretching (displacement of 3.5 mm) is measured.
