PPKMARKMarking nappies and flexible packaging on a film line
A UV laser marks the DataMatrix directly on the film with minimal heat on the material. The flow is split between three packing posts, so the line does not slow down for marking. In the flexible-packaging video a code goes onto a bag in 0.35 seconds.
Line components
What goes on a film line
355 nm UV laser
Film and flexible packaging are marked with a 355 nm ultraviolet laser: it gives a crisp DataMatrix with minimal heat input, so the film does not warp or melt at the edge of the code.
Synchronised with web speed
Marking is driven by a sensor or by the actual line speed, not by a timer. That is why the code lands in the same place on every pack, even when the web runs unevenly.
Every code inspected
Right after marking an industrial camera reads the DataMatrix and checks print quality. An unreadable code sends the item out of the flow automatically, with no operator involved.
Flow splitting
Product is distributed between packing stations, so no single station becomes a bottleneck and the line does not slow down for marking.
Why us
Film does not forgive speed
On film at high speed ordinary solutions start missing codes. We match the laser to the material and synchronise marking with the actual web speed.
Our own workshop
We make mounts and non-standard assemblies ourselves — no waiting for a supplier and no bending your line to fit an off-the-shelf solution.
Own software
PPKLink and PPKVision are ours. 1C integration needs no outside developers.
One contractor
Design, supply, installation, commissioning and shift training in one pair of hands — no passing the buck.

FAQ
Answers before the call
Does the laser burn through the film?
No. Film and flexible packaging use a 355 nm ultraviolet laser: it gives a sharp code with minimal heat on the material. That is why film lines use a UV laser rather than CO₂ or fibre.
What line speed can it handle?
The ceiling depends on the material, code size and inspection requirements — we calculate it at the audit. In the flexible-packaging video a code goes onto a bag in 0.35 seconds.
What if one packing station cannot keep up with the line?
The flow is split between stations: product is distributed automatically, so no single station becomes a bottleneck and the line does not slow for marking.
Does this product group need aggregation?
If you need it, we add it to the same station: cases are built, pallets counted, data goes to 1C and Chestny Znak. Whether you need it depends on the requirements for your product group.
