System and methods for generating laser markings on metallised substrates

An apparatus comprising:

• a fiber laser operable to produce a laser beam, wherein the laser beam is produced at a wavelength of 1.06 μm;
• an optics assembly operable to focus and direct the laser beam onto a non-metalized layer side of a substrate, wherein the substrate comprises the non-metalized layer side comprising a non-metalized material and a metalized layer side comprising a metalized material, the metalized layer side being opposite the non-metalized layer side;
• and
• electronics communicatively coupled with the fiber laser and the optics assembly, the electronics being operable to control the fiber laser and the optics assembly, based on one or more laser settings, to (i) direct the laser beam through the non-metalized layer side to be absorbed by the metalized layer side, (ii) generate a laser marking on the metalized material, and (iii) avoid generating the laser marking on the non-metalized material;
• wherein the electronics are further operable to direct the laser beam to a determined marking area portion of the metalized layer side, after the substrate is already attached to seal a product packaging, wherein the marking area portion is positioned outside of a sealing portion of the substrate used to seal the product packaging, and wherein the marking area portion is determined based on an absorption rate of one or more inks associated with a corresponding portion of the non-metalized layer side to avoid generating the laser marking on the non-metalized material;
• wherein the one or more laser settings comprise a laser power setting, a frequency setting, a marking speed setting, and a focal distance setting;
• and
• wherein the marking area portion is determined based on the absorption rate of at least one color of the one or more inks.
