Siegwerk and Ravenwood partner to advance linerless labels

Siegwerk and Ravenwood Packaging have partnered to accelerate the adoption of sustainable linerless labels across the packaging industry. As part of this collaboration, Siegwerk has developed and submitted two BPA-free release varnishes now approved for use on Ravenwood’s linerless label systems.

These varnishes meet the stringent requirements of the Nestlé Guidance, as well as the Swiss and German Ink Ordinances, making them fully compliant for nutrition, pharma and hygiene (NPH) applications.

As mentioned before, the varnishes comply with the German Ink Ordinances (GIO), a harmonized set of regulations developed to ensure the safety and regulatory compliance of printing inks used in food packaging. The GIO framework facilitates international market access by aligning ink formulations with strict migration limits and toxicological standards, thereby supporting food safety and consumer protection.

'We are excited to collaborate with Ravenwood to bring high-performance, sustainable solutions to the market,' said Guido Lander, vice president, business unit narrow web, EMEA at Siegwerk. 'This partnership reflects our shared commitment to innovation and environmental responsibility.'

The companies are working closely to align marketing efforts and explore further opportunities for joint innovation. 'We see this as a significant step forward in enabling circular packaging solutions,' said Dan Coe, director at Ravenwood. 'Siegwerk’s expertise in coatings perfectly complements Ravenwood’s linerless technology.'

Linerless labels are a good alternative to traditional pressure-sensitive labels. Unlike conventional labels, they do not require a silicone-coated release liner, which significantly reduces material waste and environmental impact. This technology offers benefits such as increased label yield per roll, reduced storage and transportation costs, and improved sustainability by minimizing landfill waste.

A joint appearance and announcement are planned for the upcoming Labelexpo, where both companies will showcase the benefits of their integrated product.
