Abstract
The present disclosure relates to methods of scoring packaging structures, including multi-layer polymeric films incorporating an encapsulated oxygen-impermeable layer, using laser energy. The methods are able to score structures which contain an oxygen-impermeable barrier without disrupting the permeability characteristics of the structure, and retain good printability, clarity, and gloss.
