NOVELTY - A composite multilayer film has a polyolefin resin film (A) arranged on one surface of an aluminum layer (B) and a polyamide layer (C) arranged on the other surface of the aluminum layer (B). The polyolefin resin film (A) has a layer (A-3) which is arranged between a layer (A-1) containing acid-modified polyethylene resin ( alpha ) and a layer (A-2) containing crystalline polyethylene resin ( beta ). The aluminum layer (B) is laminated on the layer (A-1). The layer (A-3) comprises a resin composition ( gamma ) containing polyethylene resin (a) and adsorption functional filler (b).    USE - Composite multilayer film is used for cladding material of lithium-ion secondary battery used as motor vehicle battery and hybrid battery, and electrical double layer capacitor (both claimed), and packaging material of strong soluble liquid, unprocessed aluminum liquid and iced confectionery e.g. ice cream. Can also be used for curry, shampoo, liquid detergent, repacking articles, retort foods, curry, industrial chemical agent, solution and solvent.    ADVANTAGE - The composite multilayer film has favorable adhesive strength and excellent low-temperature resistance.    DETAILED DESCRIPTION - A composite multilayer film has a polyolefin resin film (A) arranged on one surface of an aluminum layer (B) and a polyamide layer (C) arranged on the other surface of the aluminum layer (B). Surface(s) of the aluminum layer is subjected to chromium conversion coating. The polyolefin resin film (A) has a layer (A-3) which is arranged between a layer (A-1) containing acid-modified polyethylene resin ( alpha ) and a layer (A-2) containing crystalline polyethylene resin ( beta ). The aluminum layer (B) is laminated on the layer (A-1). The layer (A-3) comprises a resin composition ( gamma ) containing polyethylene-type resin (a) (100 parts mass) and adsorption functional filler (b) (1-300 parts mass). The average particle diameter of adsorption functional filler is 20 mu m or less. The particle-diameter (D99) of adsorption functional filler is 30 mu m or less. The 60%-crystallinity degree of the acid-modified polyethylene resin ( alpha ) is less than 60%-crystallinity degree of the crystalline polyethylene resin ( beta ). An INDEPENDENT CLAIM is included for manufacture of composite multilayer film.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the composite multilayer film.
