Compared to fiber lasers, which excel in processing various metallic materials, CO2 lasers have a unique advantage with their mainstream wavelength, making them ideal for marking transparent materials.
Although UV (ultraviolet) lasers can produce ultra-fine markings within small areas, CO2 lasers fall slightly short in this regard.
However, this does not diminish the importance of CO2 lasers in the marking industry, where they are widely used on various packaging materials such as mineral water bottles, snack packaging bags, corrugated cardboard boxes, and coated paper labels.
High-power CO2 laser marking is increasingly becoming an industry standard. It not only handles the production demands of marking tens of thousands of water bottles per hour but also efficiently processes large amounts of data within limited timeframes, aided by high-speed galvanometers and laser control software.
Wood processing is another area where CO2 lasers excel.
From niche applications like custom marking on wooden and bamboo handicrafts and denim fabrics to large-scale production applications such as ice cream sticks, CO2 lasers demonstrate exceptional efficiency. Their non-contact marking process ensures the product remains uncontaminated, and the absence of consumables (e.g., ink or other chemical solvents) further streamlines the process.
In certain specialized applications, CO2 lasers make the most of their strengths. For instance, while their mainstream wavelength may struggle to mark raw metal surfaces, it is particularly effective for laser marking on coated metals.
This approach allows the laser to penetrate the coating while preserving the underlying substrate, delivering more durable, clearer, and finer marking results without being limited by adhesion factors.
In the case of packaging films (e.g., shrink films), CO2 lasers have been innovatively applied to perforate easy-tear lines.
The laser can adjust to the composite film’s thickness, production line speed, and shrink/stretch forces. Precision in perforation spacing and line width ensures the finished product is easy to tear while remaining durable during heat shrinking. The non-contact nature of laser processing also avoids contamination issues that might arise from direct contact.
The applications of CO2 lasers are ever-evolving. Through continuous professional innovation and development, they will unlock even greater potential in the future.
