Laser Marking Machines

A laser marking machine creates permanent, label-free identification directly on a product or its packaging. This is used where conventional adhesive labels are impractical — due to surface material, temperature, or the need for identification that cannot be detached, damaged, or falsified. Common applications include marking expiry dates, barcodes and QR codes, batch codes, and serial numbers onto blister foils, glass containers, cartons, and plastic packaging. BCI offers laser marking as part of its track-and-trace and automated identification hardware portfolio.

Labels can peel, fade, smear, or be removed — all of which can compromise traceability, compliance, or consumer trust. Laser marks are permanent, tamper-proof, and resistant to heat, chemicals, and abrasion. In pharmaceutical packaging, glass containers, and food packaging lines where label adhesion is unreliable, laser marking ensures that the identification survives the full product lifecycle — from production through distribution to end use.

Laser marking is compatible with a wide range of industrial packaging materials, including blister foils (aluminium and PVC), glass, plastics (PET, HDPE, LDPE), carton board, and certain metals. The specific laser type (CO₂, fibre, or UV) determines compatibility with different material types. BCI can specify the correct laser system based on the target substrate in a given production environment.

Laser marks can carry serialised codes, GS1 DataMatrix codes, batch and lot numbers, and QR codes — exactly the data required for track-and-trace workflows. Because the mark is integral to the product surface rather than a removable label, it provides a permanent, verifiable link between the physical item and its digital record. This is particularly valuable in pharmaceutical and food manufacturing where regulators require end-to-end traceability.

Yes. Laser marking systems can be integrated into production and packaging lines as inline stations, triggered by line PLC or WMS signals to mark each item as it passes through. BCI integrates laser marking hardware with its broader track-and-trace and manufacturing execution solutions so that the mark event is logged, verified, and linked to the production record automatically.

Laser-marked barcodes and Data Matrix codes can be read using compatible barcode scanners or machine vision systems. In most cases, no special equipment is required, provided the scanner supports reading direct part marks (DPM) or laser-etched codes. The choice of scanner depends on the marking type, material, and application.
