Siegwerk and Enplater Group have jointly developed a fully recyclable mono-material polypropylene (PP) pouch designed to deliver barrier and sealing performance for food packaging applications.
The companies announced that the development combines Siegwerk’s ink and coating technologies with Enplater’s converting and packaging expertise to create a mono-PP structure intended to support recyclability targets while maintaining packaging functionality. The project involved production trials under commercial manufacturing conditions to optimise the pouch structure for food packaging applications.
According to the companies, the pouch is designed to provide barrier and sealing properties comparable to conventional multi-material flexible packaging structures while supporting design-for-recycling requirements linked to upcoming European Packaging and Packaging Waste Regulation (PPWR) guidelines.
The development uses Siegwerk’s oxygen-barrier and white ink technologies applied inline to help replace conventional materials such as PVdC, metallised films and EVOH-based structures. The pouch structure also incorporates polyurethane-based ink systems intended to support print quality and adhesion in flexible packaging production environments.
“As the packaging industry continues its transition toward circular solutions, collaboration across the value chain is essential to keep driving innovation forward,” said Javier Garcia. “By combining our advanced ink and coating technologies with Enplater’s specialized converting expertise, we have been able to develop a mono-material PP pouch that performs on-par with existing multi-material barrier solutions, while driving the material efficiency necessary to meet the strict Design for Recycling mandates of the upcoming PPWR.”
The companies stated that the project highlights ongoing efforts within the flexible packaging industry to develop recyclable mono-material packaging structures without compromising technical performance.
