Direct-to-package marking · Rigid packs

MarkLine™

MarkLine™ is the LasX machine for direct-to-package marking on bottles, caps and other rigid packs — no ink, no label, no consumable in the marking step. Packs convey past a bank of LaserSharp® modules, single-sided or in 360° rotation, so date and lot codes, serialized or covert security marks, embellishment and full label-replacement graphics become part of the package rather than something applied to it.

Features on a web — scoring, perforating, contour cutting, foil — run on FocusPro™, FoilPro™, MicroLam™ or SmartFinish™. A LaserSharp® module in a line that already has its own conveyance is the LaserSharp® LPM. More than 16 modules is quoted as custom equipment.

Lanes	SingleLane, DualLane, or MultiLane (three or more lanes)
Mark type	Inkless, direct-to-package; durability verified on your package
Content	Fully variable, unit-levelDate/lot, serialization, covert security marks, embellishment, label-replacement graphics.
Laser modules	One to 16 modulesModule count scaled to line rate and mark area; sixteen modules on one machine is the largest configuration in production. More than 16 is custom.
Laser source	Matched to the substrate — UV, green, NIR, or CO₂

µVerify™ — in-line inspection that measures feature size and position and feeds closed-loop control of the laser parameters, plus Pulse beam confirmation. Which features are measured depends on the application.

A mark that is part of the package changes what packaging can be asked to carry — serialized codes, covert brand-protection marks, and full label graphics, without a label to apply or an ink to run out.

Questions buyers ask

What does laser marking replace on a package?

Ink, ribbon, or label in the marking step, and their changeovers. Because nothing is added to the package, the mark is compatible with recyclable mono-material structures. Durability is verified on your package and artwork; extraction filters, optics, and other machine consumables depend on the configuration.

Do we need a trial before a quote?

Yes. Every MarkLine™ quote follows a PhotonX trial on your package and artwork, where durability, contrast and rate are proven before a machine is specified.

Is this proven in production?

LasX and Procter & Gamble launched LaserSharp® Marking on Tide® Ultra OXI Boost, and the program was named Best in Class at the 2026 PAC Global Awards.

Where does the variable data come from?

LightGuide® builds each mark from the job and live data — the date and time, the job name, or a value sent from your line's control system, such as a lot or serial number — so every unit can carry a different code without redrawing the design.

Can it mark curved surfaces?

Yes — 360° rotation handling marks the full circumference of bottles and containers, and single-sided configurations handle flat or gently curved faces inline.

Can LasX mark packs for us?

For PhotonX trials, and as a bridge while your MarkLine™ is built. LasX does not run pack marking as a standing production service.

Is MarkLine™ a new machine?

No. MarkLine™ is the machine platform formerly the LaserSharp® Marking Workstation, renamed in 2026. LaserSharp® Marking remains the name of the process, and LightGuide® the software.
