METHODS OF LASER SCORING MULTI-LAYER FILMS AND RELATED STRUCTURES

摘要

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.

主权项

1. A method for scoring a multi-layer film structure comprising,
obtaining a multi-layer film comprising at least one outer layer and an encapsulation layer,
wherein the encapsulation layer comprises an encapsulation material that encapsulates the barrier layer,wherein the barrier layer comprises an oxygen impermeable material, and laser scoring the multi-layer film structure such that the at least one outer layer of the multi-layer film structure is scored.
