Laser marking on plastics
There are different types of plastics such as polycarbonate, polyamide, polyester, PE, ABS, and many others that influence the choice of laser in terms of wavelength required. The different sources in our laser range allow us to mark on all types of plastics. Laser marking on plastics removes or modifies the surface of the plastic material or changes its color to create contrast.
The most common polymer in the plastic family is PET. . It is lightweight and also very strong. These properties make it ideal for liquid containers such as plastic bottles and food. PET can be combined with aluminum or metal film, which reduces its permeability and makes it reflective and opaque. The qualities make it ideal for flexible food packaging.
Laser marking with CO2 laser or DPSS are ideal for plastics. Marking on PET requires a specific short wavelength (9.3 μm) achieving laser marking with white characters. From PET bottles to thin-film materials, laser marking with the right parameters will always be obvious, clean and sharp.
