delfort, a global specialist in specialty papers, has partnered with Rieusset, a leading packaging producer under the Gerosa Group, to introduce an innovative paper-based packaging solution for ice lollies. The collaboration has resulted in a product that combines sustainability with functionality, as the newly developed packaging—based on delfort’s thinbarrier 201—makes its way from Germany to retailers across Europe.

Replacing traditional plastic wrappers, thinbarrier 201 delivers effective moisture resistance and prevents flavour loss, two critical aspects for maintaining the quality and texture of frozen treats. This new solution also provides a barrier against freezer burn and drying, ensuring that ice lollies retain their original taste and consistency throughout their shelf life.

“This ensures that the ice cream retains its quality, taste and consistency throughout its entire life cycle,” said Peter Hackl, Director of Packaging at delfort.

Recyclability and Responsible Sourcing

One of the standout features of thinbarrier 201 is its verified recyclability. It has passed testing under the Confederation of European Paper Industries (CEPI) method, confirming its compatibility with existing recycling streams. Moreover, all pulp used in the paper comes from sustainably managed forests, with full FSC and PEFC certification, aligning with the increasing demand for responsible sourcing and circular materials.

According to Guillem Pérez González, Director of Purchasing at Rieusset, the environmental motivation behind the switch was clear: “Sustainability is more than a trend; it’s a responsibility. We chose thinbarrier 201 because it aligns with our eco-design guidelines and delivers excellent performance.”

Seamless Integration into Existing Systems

Despite initial concerns about the switch from plastic to paper, delfort and Rieusset ensured the new packaging material could be processed on existing machinery without significant adaptation. The paper is heat-sealable and compatible with tubular bag packaging formats. It is also printed using gravure printing, providing high-quality, consistent visuals that meet branding expectations.

Joaquin Vidal Domene, Director of Technical & R&D at Rieusset, acknowledged the early hesitation among production teams: “There’s often some scepticism when introducing paper-based alternatives. But once our teams handled delfort’s paper, they quickly realized how smoothly it runs on current equipment.”

Driving Sustainable Innovation in Frozen Food Packaging

This initiative represents a wider shift in the food packaging sector, where recyclability and renewable materials are now crucial elements of product development. Paper packaging solutions such as thinbarrier 201 are proving that sustainability and performance no longer need to be mutually exclusive.

As regulatory pressure increases and consumer preferences continue to evolve, collaborations like the one between delfort and Rieusset show how packaging innovation can actively support both brand values and environmental goals. Their joint efforts offer a scalable, practical solution that can inspire similar transitions across the frozen dessert category and beyond.

This paper-based advancement isn’t just wrapping ice lollies—it’s wrapping up a new era of sustainable packaging for the frozen food industry.
