Applied to the substrate in coatable or ink form by a paper manufacturer or converter, non-pigmented Ciba’s Pergamark laser-marking solution yields stable, high-contrast black images. With all non-toxic additives and no ink at the point of printing, Pergamark allows variable data to be printed on demand with a low-power CO2 laser in the final stage of the packaging process. All components of Pergamark are in line with food contact regulations.
