MANUFACTURING METHOD OF ALUMINUM FOIL FOR LAMINATION, ALUMINUM FOIL FOR LAMINATION AND LAMINATE MATERIAL

摘要

PROBLEM TO BE SOLVED: To manufacture an aluminum foil for lamination excellent in adhesion to a synthetic resin by a simple method.;SOLUTION: In an aluminum foil manufacturing method comprising a hot-rolling step, a cold-rolling step including intermediate annealing, a foil rolling step and a final annealing step, the final annealing step is performed in a controlled atmosphere with a low humidity. The absolute humidity in the atmosphere is preferably ≤6 g/m³. The humidity in the final annealing atmosphere is controlled by cooling the atmosphere introduced into an annealing furnace or by contacting it with a dehydrating agent.;COPYRIGHT: (C)2009,JPO&INPIT
