Abstract

A device and method for opening containers utilizing laser-etched pull tabs and methods of making the same. According to the invention, indicia is laser-etched on a pull tab substrate, which may be made of any suitable material, by selective laser ablation of the substrate with a laser marker. The laser marker is preferably capable of ablating the substrate's surface to any desired depth, including depths of between 1 to 50 microns and depths that enable the etching to be detected by touch. The invention also contemplates removing one or more coating layers in addition to a portion of the exposed pull tabs surface through laser ablation to generate visually contrasting indicia for promoting or decorating the substrate surface. The pull tabs of the present invention have consistent, high definition indicia that is both tamper resistant and permanent.
