At Interpack 2014, Sun Chemical launched the newest evolution of its SunLase laser marking solutions, a coating that enables brand owners to add information to both secondary and primary packaging after the filling and closure of the pack, whether for practical supply chain purposes or as a late stage pack differentiator.
The SunLase solution prints a transparent or tinted coating onto a packaging substrate during the printing process. After the packaging has been sealed, variable coding graphic information, such as barcodes, QR codes, and “Use By” dates or branding, can be created using a low power CO2 or fibrer laser to change the color of the patch to black where marked, with no risks to the packaged product.
“In today’s market place, modern supply chain management and track-and-trace requirements mean that most packs must carry identification markings, such as barcodes,” said Eric Dejean, product manager, water-based products Europe, Sun Chemical. “Additionally, brand owners are finding that consumers want complex on-pack information about ingredients, dietary information, usage guidelines, recycling. With SunLase laser marking solutions, brand owners now have the flexibility to add information to packaging at the latest possible stage of the supply chain. This avoids the potential cost implications of more flexible, shorter-run package production and allows their packaging to become more adaptable to what consumers demand.”
Visitors during Interpack 2014 saw how SunLase works first-hand with live demonstrations provided by Videojet, a leading laser manufacturer. The demos showed how a collection of images, such as QR codes, barcodes, logos, text and serial numbers, will appear on various substrates, including corrugated board and film.
