NOVELTY - A multilayer compound film has polyolefin resin film (A) consist of acid modified polyolefin resin ( alpha ) (A-1), crystalline propylene polymer ( beta ) (A-3) and water absorbing resin composition (A-2), non-chromium processed aluminum film (B) and polyamide layer (C). The water absorbing resin composition (A-2) contains 100 mass parts polyethylene resin composition (a) consist of 99-60 mass% ethylene polymer (a-1) and 1-40 mass% acid modified resin (a-2), and 5-200 water absorptive fillers (b).    USE - Multilayer compound film for molding used as exterior material in rechargeable battery (claimed) or packaging material for foodstuff or daily necessities.    ADVANTAGE - Multilayer compound film is bonded together with sufficient adhesive strength without anchoring or adhesive agent and is sufficiently damp proof.    DETAILED DESCRIPTION - A multilayer compound film has polyolefin resin film (A) consist of acid modified polyolefin resin ( alpha ) (A-1), crystalline propylene polymer ( beta ) (A-3) and water absorbing resin composition (A-2), non-chromium processed aluminum film (B) and polyamide layer (C). The water absorbing resin composition (A-2) contains 100 mass parts polyethylene resin composition (a) consist of 99-60 mass% ethylene polymer (a-1) and 1-40 mass% acid modified resin (a-2), and 5-200 water absorptive fillers (b) with less than or equal to 30 mu m particle diameter (D99) contained at 99 mass% and less than or equal to 20 mu m particle diameter (D50) contained at 50 mass%. The melting point peak at the side of the highest temperature in differential scanning calorimetry melting curve of acid modified polyolefin resin ( alpha ) is set as Tm alpha . The crystallinity degree Xc(Tm alpha ) of crystalline propylene polymer ( beta ) in Tm alpha is greater than or equal to 60%. The peak melting point Tm of ethylene polymer (a-1) is greater than or equal to 110 degrees C, heat of fusion ( Delta ) is 90-180J/g, degree of crystallinity (Xc110) in 110 degrees C is 10-60% and melt flow rate at 190 degrees C and 21.18 N is 0.1-10 g/10 minutes. An INDEPENDENT CLAIM is included for manufacture of multilayer compound film which involves laminating layers (A) and (B) where layer (B) is laminated to layer (A-1) and laminating layer (C) on layer (B). The laminating process is performed by hot lamination at a temperature which makes the degree of crystallinity greater than or equal to 60%.
