HEAT-RESISTANT FLEXIBLE LAMINATED SHEET AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a heat-resistant flexible laminated sheet suitable as a flexible substrate material and having a low dimensional change ratio and good adhesiveness. SOLUTION: The heat-resistant flexible laminated sheet is obtained by laminating a metal foil and a heat-resistant adhesive film, and the peel strength of the metal foil at a peel angle of 180 deg. is not less than 10 N/cm and the dimensional change ratio before and after the removal of the metal foil is -0.1-+0.1%. This heat-resistant flexible laminated sheet is manufactured by a method including a process for molding the metal foil and the heat-resistant adhesive film in the nip between at least a pair of press rolls, under pressure and heating, between which protective materials are arranged, a process for cooling the obtained laminate and the protective materials while lightly bringing them into close contact with each other, and a process for peeling the protective materials from the laminate.
