Method and device for manufacturing a polyethylene object marked with a machine readable code

摘要

A machine-readable encoded information marker (3) is applied with bundled laser radiation on an object 's surface (8) by impinging a marking section (9). Laser radiation (10) is generated by a source (21) of high-power laser beams and has a wavelength, for which the object has a high transparency. An independent claim is also included for a device for producing a polyethylene object with a machine-readable encoded information marker.
