Siegwerk, a global provider of printing inks and coatings for packaging applications and labels, and Ravenwood Packaging, a pioneer in linerless labeling technology, have announced a strategic partnership aimed at accelerating the adoption of sustainable linerless label solutions across the packaging industry.

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

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.

Compliance

As mentioned before, the varnishes comply with the German Ink Ordinances (GIO). This serves as 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,” says Guido Lander, vice president, Business Unit Narrow Web EMEA, 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,” remarks Dan Coe, director at Ravenwood. “Siegwerk’s expertise in coatings perfectly complements Ravenwood’s linerless technology.”

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