A sheet of material that is marked with a pulsed laser, the sheet of material having an outer edge and an inner edge separated by a core. The distance from the outer edge to the inner edge is the sheet thickness. The sheet of material has a total concentration of TiO2 of less than about 1.00%. There is an exterior layer beginning at the outer edge and extending into the core, the thickness of the exterior layer is from about 10.00% to about 40.00% of the sheet thickness, and the exterior layer has an average concentration of from about 2.50% to about 10.00% TiO2.
A sheet of material that is marked with a pulsed laser, the sheet of material comprising an outer edge and an inner edge separated by a core, the distance from the outer edge to the inner edge being the sheet thickness, and there is an exterior layer beginning at the outer edge and extending into the core, the thickness of the exterior layer is from about 10.00% to about 40.00% of the sheet thickness, wherein the exterior layer has an average concentration of from about 2.50% to about 10.00% TiO2, wherein the pulsed laser marking is formed by absorption of the pulsed laser by the TiO2 in the exterior layer, wherein the pulsed laser marking comprises a predetermined pattern including alphanumeric text, a machine-readable code or symbol, or both, and wherein the sheet of material forms an article selected from the group of a garbage bag, a bottle, a sachet, a tube, a film, a laminate, a bag, a wrap, a drum, a jar, a cup, or a cap.
A sheet of polymeric material that is marked with a pulsed laser, the sheet of polymeric material comprising an outer edge and an inner edge separated by a core, the distance from the outer edge to the inner edge being the sheet thickness, and there is an exterior layer beginning at the outer edge and extending into the core, the thickness of the exterior layer is from about 10.00% to about 40.00% of the sheet thickness, wherein the exterior layer has an average concentration of from about 2.50% to about 10.00% TiO2, wherein the pulsed laser marking is formed by absorption of the pulsed laser by the TiO2 in the exterior layer, wherein the pulsed laser marking comprises a predetermined pattern including alphanumeric text, a machine-readable code or symbol, or both, and wherein the sheet of polymeric material forms an article selected from the group of a garbage bag, a bottle, a sachet, a tube, a film, a laminate, a bag, a wrap, a drum, a jar, a cup, or a cap.
