Abstract

A method of scoring a multi-layer film structure, wherein the multi-layer film structure comprises a metal layer and polymer layer bonded to each other, the method comprises using a single laser beam incident to the polymer layer to produce a score line in the polymer layer, wherein the laser energy is absorbed only by the metal layer.
