An object of the present invention is to provide a method for producing a laminate film which is excellent in adhesiveness and tears easily (tearability). A laminating adhesive comprising a hydroxyl group-terminated polyurethane resin (A) and a polyisocyanate curing agent (B) in a mass ratio of (A) :( B) = 100: 30 to 100: 100 is inorganic. In a method for producing a laminated film, which is applied to a plastic film having a layer formed thereon, and a heat-fusible plastic film is bonded and heat-cured, (A) the isocyanurate-modified poly (hexamethylene diisocyanate) having a substantial average number of functional groups of 2, a number average molecular weight of 10,000 to 50,000 and (B) a substantial average number of functional groups of 2 to 10; The problem is solved by a method for producing a laminate film, which is characterized by being an isocyanate.
