Method for lamination of film layers in e.g. smart card during manufacture, involves softening lower film layer before softening of carrier film layer

摘要

The method involves stacking basic carrier film layer (10) and upper film layer (30) under formation of film layer stack (100). The lamination of film layers under formation of film layer laminate is performed by heating the film layer stack, so that a composite of film layers in film layer stack is produced. The upper film layer is softened before softening of carrier film layer. The upper film layer is made of polycarbonate.
