CO₂ laser marking machines use high-power infrared radiation (typically 10.6 μm wavelength), which is particularly effective in processing organic and non-metallic materials. These machines are ideal for wood, paper, leather, acrylic, plastic, glass and textiles, providing fast and high-quality engraving or cutting. CO₂ markers work by vaporizing the surface layer of the material with the help of heat, creating clear and durable markings. They are widely used in the advertising industry, packaging production, food and beverage labeling, as well as crafts and design products, where both aesthetics and functionality are important.
