FIGURE 1. Dark marking contrast (top), white marking contrast (left), and custom color (right). Improved Contrast, Line Edge Detail, and Speed The newest generation of laser marking “smart additives” incorporated into polymers is a quantum leap in technology, which is both enabling and cost-saving. These advanced material science formulations achieve unprecedented marking contrast, line edge detail, and speed on plastics that have traditionally been difficult, if not impossible, to laser

Fast speed, superior contrast and cost-savings are among the significant benefits of incorporating novel FDA-approved additives into polymers for laser marking. Chemical additive breakthroughs produce jet black and light-colored contrast on molded and extruded products, both “on-the-fly” and during secondary operations. Designed for affordable fiber lasers, inline inkless laser marking now replaces rotary gravure and pad printing. Product applications Many clear, semi-transparent and opaque colored polymers, including nylons, PET, polycarbonates,

Laser marking offers advantages over in-mold labeling and ink-based printing for direct part marking on plastic products. The emergence of ytterbium fiber lasers further distinguishes lasers as an important method for adding security and anti-counterfeit measures. Industrial manufacturing requirements for indelible direct part marking containing machine vision codes are growing rapidly. Three familiar code types are QR, Data Matrix and barcode. Direct part marking allows tracking a single unique product

The demand for high-contrast laser marking on nylon (polyamide) plastic products is rapidly increasing due to its wide range of industrial applications. Functional and decorative markings include alphanumeric identification, data matrix/QR vision codes, diagrams and micro-structures. Polyamides, including Polyphthalmides (PPA), are among the most challenging polymers to laser mark due to their diverse material properties, molding conditions and laser configurations. Smart additives for near-infrared lasers solve marking contrast problems and

Breakthrough FDA-approved additives blended into polymers during primary processing optimize laser marking of plastics. Fast speed, superior contrast, and cost savings are among the significant benefits. Novel chemical additives can produce jet-black, light-colored, and custom color contrast, using both “on-the-fly” and secondary operations. Designed for affordable ytterbium fiber lasers, in-line inkless laser marking now replaces traditional rotary gravure and pad printing.
