Method for producing flexible laminate

摘要

It is an object of the present invention to provide a method for producing a flexible laminate in which the appearance and dimensional stability after removal of metal foils are improved. The present invention provides a method for producing a flexible laminate 5 including a heat-resistant adhesive film 3 and a metal foil 2 bonded to at least one surface of the heat-resistant adhesive film 3 . The method includes a step of performing thermal lamination by passing the heat-resistant adhesive film 3 and the metal foil 2 between a pair of metal rolls 4 through a protective film 1 , and a step of separating the protective film 1 . The molecular orientation ratio of the protective film 1 is in a range of 1.0 to 1.7.
