Abstract
A system and method for producing a partially perforated tear line on a substrate material uses an high energy beam to ablate the substrate material at a depth less than full depth of the substrate. By varying the output energy level of the high energy beam for varying time intervals, a substrate material is weakened to provide an easy open feature without significantly reducing the tensile strength of the substrate material. The ratio of partial perforated to unablated substrate material may vary according to almost any ratio.
