REA JET: Laser marking system for thin-walled plastics

REA JET offers a new laser system that is capable of marking thin plastics without the risk of perforation; to meet stability requirements a specific wavelength is used and the important barrier and burst pressure properties are preserved.

The consumable- and nearly maintenance-free laser REA JET CL is available with safety class IP65 for use in humid environments, making it suitable for the beverage industry.

Average CO2  laser systems normally use a wavelength of 10.6 µm to generate an engraving on PET bottles. Outdated or inappropriate laser sources can severely damage thin container walls. In contrast, the REA JET CL can also be operated with the specific wavelength of 9.3 µm that foams up plastics during the marking process. Thus a perforation is avoided and the stability of the material is kept. A further advantage of this wavelength is the significantly better legibility of the marking. The foamed material appears whitish, while an engraving remains transparent and a contrast is only caused by shadow.
