When laser marking on plastic, particularly PET bottles, a CO2 laser can deliver a unique interaction with
the plastic surface. This interaction yields a frosted effect on a bottle or container to produce visible,
permanent codes. Choosing the right laser requiresmatching the laser wavelength to the PET’s thickness.
To make this match, CORRECT PACK laser experts help evaluate substrates, provide marked samples, and
make recommendations to meet code and speed requirements.
