<P>PROBLEM TO BE SOLVED: To provide a laminated film for packaging which can form characters, marks or the like without being subject to a constraint on design, and without exposing either surface of the laminated plastic film itself, and wherein the fear for the adhesion of droplets of an inject to an unintended section, and the fear for the splashing of an ink solvent in a food factory have been eliminated. <P>SOLUTION: In either interlaminar space of two layers or more of transparent plastic films which are laminated to each other, an ink layer of a high laser beam absorbing rate is provided. An ink in the ink layer is locally sublimated, dissipated or eliminated, and a part of the ink layer is fractured. Thus, at least one kind of characters, figures and marks is formed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
