PROBLEM TO BE SOLVED: To provide a laminate film for metal lamination showing sufficient adhesion strength to a metal material, excellent high speed lamination on the metal material, excellent appearance after lamination and excellent fabricability in can-making. SOLUTION: A laminate film comprises an adhesive layer made of an unsaturated carboxylic acid-modified polypropylene-based resin and one or more stretched polypropylene-based resin layers wherein the laminate film has one endothermic peak in a differential thermal curve by means of differential scanning calorimetry and shows a crystallization degree of not less than 60% and the crystallization degree of 30 to 50% after being melted, each being measured by means of a vertical beam X-ray diffraction method. |
