Better traceability
The Linx SL1 laser coder has provided the ideal solution for the application of permanent codes onto paper cups, as part of the upgrading of product traceability at global food and drink packaging specialist Huhtamaki’s New Zealand operation.
Huhtamaki identified laser technology as the most appropriate solution to ensure an indelible code and to meet the company’s requirements for improved cleanliness and lower operating costs.
The application was not an entirely easy one, as Huhtamaki Engineering Manager Greg White explains: “We have multiple production lines based on differing converting machines, meaning each installation had its own engineering challenges. Speeds are high, space is tight, health & safety is critical, and production downtime is something we just cannot afford.”
After evaluating different vendors, Huhtamaki selected the Linx SL1 laser coder supplied by Linx distributor Reynolds. “We compared a number of potential vendors, and selected Reynolds based on their strong engineering capability and history of excellent post-sales service,” says Greg.
The five Linx SL1 laser coders are integrated into the different packaging machines, complete with comprehensive safety interlocking and guarding. The SL1 units are ideal due to their highly compact size, flexible configuration and excellent price to performance ratio.
The coder was designed as a cost-effective and compact model. The highly flexible 10W laser delivers a wide range of message types, including multiple lines of high quality text, logos and machine-readable codes, while its small dimensions and light weight mean it is simple to position on the line and fits easily into tight spaces, coding in any orientation.
The Linx SL1 delivers class-leading coding speeds thanks to the use of lightweight and ultra-fast mirrors. It offers 20 per cent more power than other products in its class, but at the same time uses much less laser energy in the coding process, which together with its robust stainless steel design further enhances its reliability and longevity.
Huhtamaki is very happy with the installation. “Some of the installs were very tricky, and it’s great to know we have a really capable partner like Reynolds,” concludes Greg. “In fact, Reynolds has now implemented automated verification systems to ensure the correct packaging variants are being run on the lines. It’s a real advantage having one partner who can deal with all the traceability and verification systems.”
