alphaJET | Marking PE tubes and pipes

Durable marking of PE plastic is a real challenge for inkjet printers: In practice, PE tubes are pre-treated with a fire flame before marking in order to roughen the material slightly. This pre-treatment improves ink adhesion. The disadvantage of this solution is increased costs due to additional energy and time expenditure.

That is why more and more manufacturers are trying to do without flame treatment. But how can good adhesion be achieved here?

Nowadays, cold PE pipes are reliably marked with the standard PEU ink without pre-treatment with flame.

The good adhesion of the ink achieves top ratings and beats the competition by far in a direct comparison. The tubes are manufactured in accordance with DIN EN ISO standards.

At the end of the production line, the tube material is marked with a variety of information, e.g. ISO number, manufacturer's name, outside diameter, wall thickness, class, material designation, permissible operating pressure, production location and date.
