Abstract
The presently preferred embodiments relate to film structures that are exposed to focused energy to provide a score line on an internal layer of the film structure, or on both an internal layer of a film structure and an outer layer of the film structure. In addition, the present invention relates to a package that may be torn along the score line. More specifically, the package may have a score line provided on an internal layer of barrier material, such as ethylene vinyl alcohol copolymer, polyvinylidene chloride copolymer, nylon, or any other laser scorable barrier material. The score line in an internal layer and/or in the surface of the film may allow the package to be opened using tearing forces, thereby exposing a product within the package and allowing a user of the package to gain access to product that may be contained therein.
