Linx UVG5
UV Laser Coder
The Linx UVG5 UV laser coder is the ideal solution for permanent marking on flexible films and rigid plastics, without the need for consumables and whilst maintaining the integrity of the substrate. Providing higher production throughput through fast product marking, and with simple integration into existing lines, the easy-to-use Linx UVG5 laser redefines efficiency.
About UV Laser Marking
UV lasers are different to other marking lasers such as CO2 and fibre. UV uses high-energy photons to break chemical bonds in materials, a process known as ‘cold processing’, which minimises thermal damage to surrounding areas.
By minimising thermal stress, UV laser marking ensures substrate integrity and reduces the risk of damage, making it an ideal choice for marking sensitive materials where traditional CO2 and fibre lasers may cause undesirable effects.
UV lasers are an ideal coding solution for a diverse range of materials including delicate mono-recyclable films, glass and difficult to mark rigid plastics such as HDPE, LDPE and PP, whilst maintaining the integrity of the product.
Capable of marking human-readable text and logos as well as machine-readable codes such as 2D Data Matrix, QR including GS1, the UVG5 delivers consistent code quality to support traceability requirements.
“The Linx UVG5 UV coder is another example of Linx innovation, providing an adaptable and user-friendly solution for challenging substrates that meets a variety of coding requirements, including effective traceability. Companies can be assured of the consistent, sustainable operation of their production lines with fewer product recalls.”
Mariusz Dabrowski, Business Unit Manager – Ink & Non-CIJ Technologies, Linx Printing Technologies

Coding GS1 with UVG5
The Linx UVG5 UV laser coder is well suited to printing GS1 2D codes, delivering high‑precision, permanent marking of Data Matrix and QR formats with excellent readability and contrast to support reliable scanning and traceability.
Its UV “cold processing” technology minimises thermal stress on sensitive materials such as plastics and films, ensuring code quality is maintained even on challenging substrates, while high‑speed performance and consistent marking make it ideal for demanding production environments where GS1 compliance and accuracy are critical.
Linx’s official partnership with GS1 UK reinforces our commitment to delivering trusted, standards-compliant coding solutions. As a GS1 UK-approved provider, our products, including the UVG5 laser, are validated to print GS1-compliant 2D codes with precision and reliability.
Cleaner Coding Backed By Industry Insight
Independent testing by fume extraction experts Donaldson BOFA has shown that UV laser marking generates fewer and smaller particles than some traditional laser technologies. These findings highlight the importance of using a suitable extraction system to help maintain a clean, controlled production environment.
These insights reinforce what Linx customers already experience with the Linx UVG5 — precise, low-impact coding that delivers high-quality results on delicate materials. The UVG5 is fully compatible with a range of industrial extraction systems designed for laser processes.
