▎ 摘　　要

NOVELTY - Soft packing material comprises thermoplastic resin layer disposed on one side of the metal foil, protective layer disposed on the other side of the metal foil, adhesive layer provided between the metal foil and the thermoplastic resin layer and/or between the metal foil and the protective layer, and fluorescent marker is provided on at least one of the adhesive layer, the metal foil, the thermoplastic resin layer or the protective layer. USE - The soft packing material is useful for battery (claimed). ADVANTAGE - The soft packing material solves problem that the battery soft package material product information is difficult to trace back in the existing technology, has good product information tracing ability, after the battery hard package material enters the downstream product production, and can accurately trace the specific product information.
