Paper, Cardboard and Glass - 10.6µm Wavelength

The CO₂ laser radiation of 10.6µm wavelength gets well absorbed in applications that process materials ranging from thin paper to cardboard packaging.
Extremely good print results are also achieved on glass products. This wavelength is the most common one available with CO₂ lasers and perfectly suits the majority of packaging applications.

PET - 9.3µm Wavelength

Perfectly matched for the head absorption of plastics like PET (Polyethylene Terephthalate), the 9.3µm wavelength laser allows marking on plastic surfaces by smoothly melting the surface layer without creating pinholes or cracking the inner structure.
This is the ideal solution for the family of polyesters of thermoplastic resins. PET is wide-spreading in the beverage industry and is mostly used for producing bottles.

Film and Foil - 10.2µm Wavelength

The 10.2µm wavelength is ideally suited to marking on thin films and any types of packaging foils. Best results can be expected on painted films and foils with a thin ink layer on top. The laser energy removes the ink and generates a contrast with the next bottom layer, e. g. with the metalized composite or aluminum. Packaging materials which 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.
