Sunine Laser coding system for flexible films and foils
SUNINE economical CO2 laser marking system offers a 30 or 60-watt power output with wavelengths of 10.6 μm, 10.2 μm and 9.3 μm for various packaging substrates, including paper, cardboard, glass, or plastics, at a very wide range of production speeds. When it comes to thin films or any type of packaging foils, 10.2µm wavelength is an ideal option. The best results can be expected on painted films and foil with a thin ink layer on top. Packaging materials that absorb this wavelength very well and therefore generate the best CO2-Laser print quality are PE, HDPE, LDPE, PP, OPP, OPA, PA, PMMA, POM, PUR, ABS, and PVC.
Besides CO2 lasers, SUNINE UV laser system is another option for coding on packaging foils or thin films. Compared with CO2 lasers, UV laser produces barely smoke, which makes it more suitable for production workshops with strict requirements on particles, especially food and pharmaceutical manufacturing.
