Laser coding solutions for manufacturers
Product identification has become a critical part of modern manufacturing. Whether it's a use-by date on a food package, a batch code on a pharmaceutical product, or a barcode used to track goods through a distribution network, manufacturers need marking systems that are accurate, durable and easy to manage.
While inkjet remains a widely used technology, laser coding is attracting growing interest due to its ability to deliver permanent, high-speed marking without the consumables and maintenance requirements associated with traditional printing systems.
For manufacturers looking to strengthen compliance, improve uptime and support sustainability initiatives, laser technology is becoming an increasingly attractive option.
Why Traceability Matters
In industries such as food and leverage, pharmaceuticals, medical devices and building products, coding serves a far greater purpose than simply displaying a date or batch number. Permanent identifiers such as batch codes, expiry dates, serial numbers, barcodes and 2D codes play a critical role in product traceability, helping manufacturers track products throughout the supply chain from production through to distribution and end use.
For heavily regulated sectors, these identifiers are essential for meeting regulatory requirements, supporting product recalls, verifying product authenticity and maintaining accurate records for audits and quality assurance programs. In industries such as pharmaceuticals and medical devices, they also help combat counterfeiting and ensure products can be traced back to their source if safety concerns arise.
Unlike printed marks that can fade, smudge or become damaged during handling, laser codes are permanently etched onto the product or packaging itself. This provides a durable, tamper-resistant solution that remains readable throughout the product lifecycle.
Because laser systems operate without physical contact, they can also keep pace with high-speed production environments while maintaining consistent mark quality.
Understanding Laser Coding Technologies
Laser coding uses a focused beam of light to permanently apply information such as batch numbers, expiry dates and barcodes directly onto products and packaging. Different laser technologies are designed for different applications.
CO₂ lasers are widely used on materials such as cardboard, paper, glass, plastics and timber products, making them ideal for food and beverage manufacturing, secondary packaging and building products.
Fibre lasers are designed for marking metals and engineered plastics, making them well suited to pharmaceutical packaging, industrial components and automotive applications.
UV lasers represent the latest advancement in laser coding technology. Their shorter wavelength allows them to mark sensitive materials such as films and flexible packaging with exceptional precision. They are also helping manufacturers support more sustainable packaging initiatives by marking directly onto recyclable mono-material packaging without the need for additional labels or inks.
Why Manufacturers Are Reassessing Inkjet
Continuous inkjet technology remains a proven solution for many applications. However, manufacturers evaluating long-term operating costs are increasingly comparing it with laser alternatives.
One of the biggest advantages is permanence. Because laser marks become part of the substrate itself, they provide a level of durability that traditional printed codes cannot always achieve.
Laser systems can also help reduce maintenance requirements. Unlike inkjet printers, they do not rely on inks, solvents or cartridges, reducing consumable costs and minimising routine servicing.
Sustainability is another consideration. By eliminating consumables and reducing waste, laser coding can help support broader environmental objectives while simplifying day-to-day operations.
