Colour change specialist Sherwood Technology has launched a process which it says allows highly cost-effective, high fidelity coding of a wide range of packaging substrates using low power laser light.
DataLase inorganic chemistry can be incorporated into inks, coatings or the substrate to enable high speed laser coding at up to 350m/min. The process catalyses a simple chemical change in the ink, additive or material, creating a high contrast, stable, scuff- and U/V light-resistant image.
Coding is possible on metals, flexible packaging, board and plastics, and through polypropylene and polyethylene films, allowing images to be embedded within laminates.
Sherwood applications marketing manager Andrew Jackson explains: “DataLase eliminates the need to use high powered lasers. With no production line consumables and low emissions, it is environmentally-friendly too.”
One early adopter is Muller Dairy which is using DataLase to code both plastic and paper packs.
