Enplater and Siegwerk Develop Flexible Mono-PP Packaging with Integrated Barrier and High Sealing Performance

Through close collaboration, both companies have successfully developed a fully recyclable mono-material polypropylene (PP) packaging solution that combines technical innovation and sustainability. This jointly developed project once again demonstrates how inks and coatings, combined with packaging converting expertise, can continue to drive circular innovations.
Siegwerk, one of the world’s leading providers of printing inks and coatings for packaging and label applications, and Enplater Group, a specialist in the printing and production of rigid and flexible packaging, today announced the joint development of an innovative mono-material polypropylene (PP) packaging solution that delivers high technical performance while facilitating recyclability.
The joint development combines Siegwerk’s expertise in high-performance, regulation-compliant ink and coating systems with Enplater’s extensive knowledge and experience in rigid and flexible packaging. Through close collaboration between the technical and R&D teams of both companies, comprehensive testing was carried out under real production conditions, generating data and results that supported the optimization of the new high-barrier mono-material PP packaging structure for food applications.
“As the packaging industry continues its transition toward circular solutions, collaboration across the value chain is essential to drive further innovation,” said Javier García, Sales and Technology Director for the Iberian Peninsula at Siegwerk. “By combining our advanced ink and coating technologies with Enplater’s specialized converting expertise, we have been able to develop a mono-material PP packaging solution that delivers performance comparable to existing multi-material barrier structures, while supporting the material efficiency required to meet the design-for-recycling requirements outlined in the PPWR.”
