When selecting a laser coding solution for industrial packaging or product identification, Fiber and CO₂ lasers remain the most widely used technologies. Their wavelength, material absorption characteristics, power range, and operating cost differ greatly—making the right choice essential for production efficiency. Well-known suppliers such as Meenjet and Domino offer mature systems in both categories, giving manufacturers reliable options for different applications.
CO₂ laser coding systems operate at 10.6 μm, a wavelength strongly absorbed by organic and non-metal materials. This makes them ideal for paper boxes, PET bottles, labels, wood, flexible films, and glass. CO₂ systems commonly range from 10W to 60W for flying marking, delivering clean, high-contrast codes at high speed through thermal ablation. They are widely used in food, beverage, and pharmaceutical packaging lines, offering lower upfront cost. Brands like Meenjet and Domino provide CO₂ models optimized for continuous, high-speed production, though CO₂ tubes generally have a shorter lifespan than Fiber sources.
Fiber laser systems operate at 1064 nm, a wavelength efficiently absorbed by metals and engineering plastics. They are ideal for aluminum cans, stainless steel parts, cable sheathing, electronic components, and automotive materials. Typical marking power ranges from 20W to 100W. Fiber lasers deliver fine resolution, deep engraving, oxide-layer coloring, and long service life with minimal heat-affected zones. Because of these advantages, Fiber lasers from Meenjet and Domino are widely chosen for traceability, serial codes, and UDI marking where permanence is essential.
When choosing between the two, material type should guide your decision:
For metals and hard plastics, Fiber laser is the superior choice.
For paper-based or organic packaging, CO₂ provides excellent performance at lower cost.
Both laser types support non-contact, high-speed coding suitable for automated production lines. By matching wavelength to material absorption and evaluating long-term operational cost, manufacturers can select the most efficient solution—whether choosing a Meenjet system for cost-effective flexibility or a Domino system for large-scale, high-duty industrial marking.
