Title:
BATTERY PACKAGING LAMINATE
Document Type and Number:
Japanese Patent JP2023009437
Kind Code:
A
Abstract:
To provide a battery packaging laminate which has excellent cold formability and puncture resistance, and carbon neutrality, and also uses biomass-derived raw materials.SOLUTION: A laminate in which at least a substrate layer 1, an adhesive layer, a metal foil layer, and a sealant layer are sequentially laminated in this order is a battery packaging laminate. The substrate layer 1 is a biaxial oriented film satisfying the following conditions (a), (b), and (c): (a) thickness is 8-30 μm; (b) a biomass-derived carbon content measured by a radioactive carbon (C14) measurement is 1-30% with respect to the total carbon in the substrate layer 1; (c) puncture resistance measured by JIS Z 1707 method is 0.7 N/μm or more.SELECTED DRAWING: None
