Constantia Flexibles, the world’s third-largest flexible packaging manufacturer, will showcase its broadest ever presence at interpack 2026, with its materials running live on equipment from 30 machine suppliers throughout the trade show. This extensive on-machine visibility highlights the company’s long-standing partnerships and demonstrates how its solutions perform in real production environments.
A central focus will be the Ecolutions portfolio, Constantia Flexibles’ comprehensive range of materials designed for recycling. The portfolio comprises mono-polyethylene (PE), mono-polypropylene (PP), aluminum-based, and paper-based structures.
“Determining the right material for each product is something we assess together with our customers, on a case-by-case basis,” said Marc Rademacher, EVP Consumer Commercial, Group R&D, and Group Sustainability at Constantia Flexibles. “Seeing a broad range of our materials running on equipment across the trade show provides valuable orientation. We are proud to showcase the performance of our products, and particularly our designed for recycling Ecolutions range, in real production environments.”
Across the show, exhibitors will process Constantia Flexibles’ materials on lines representing nearly all major packaging categories. Demonstrations will cover applications such as pet food, savory snacks, dairy, milk powder, confectionery, fruit purées, nuts and seeds, dry goods, as well as selected cosmetic and pharmaceutical products.
Ecolutions portfolio in operation across machine types
Building on this broad presence, machine suppliers will showcase a selection of the EcoLam family, Constantia Flexibles’ mono PE structures, which received RecyClass Technology Approval. These will be processed in various pouch formats, including inverted pouches, stabilo bags, and stand-up pouches, many of which feature zipper reclosure systems. Meanwhile, EcoVer, the company’s mono PP portfolio, will be used on equipment producing formats such as side-gusset bags, pillow packs, stand-up pouches with spouts, and flow wraps. These demonstrations will show how PP-based materials perform reliably in standard industrial processing environments.
Constantia Flexibles’ lidding and packaging materials will be prominently featured at the show. A broad range of aluminum die-cut lids and PP-based lids, commonly used in dairy and other sensitive product categories, will be processed on high-speed machinery at several exhibitor booths. In the paper segment, multiple wrapper and flow-pack lines will run EcoPaper materials engineered for strong printing performance, reliable machinability, and available in various barrier grades. These solutions will also be demonstrated in fold-wrap applications and selected chocolate bar flow-packs, allowing visitors to see their versatility in live production.
Constantia Flexibles already offers its packaging solutions in PFAS-free designs upon request and is well advanced in converting its global production network to PFAS-free manufacturing, a major transition that began ahead of PPWR requirements. Fully in line with regulations, Constantia Flexibles will remove PFAS-containing packaging entirely from its portfolio. Several plants are already well progressed, and the remaining locations continue to move forward as planned, ensuring readiness ahead of the August 2026 deadline under the Packaging and Packaging Waste Regulation (PPWR).
Pharmaceutical materials highlighted on partner machinery
In addition to consumer packaging, interpack will also highlight several of Constantia Flexibles’ specialized pharmaceutical materials. The company’s PP-based PERPETUA solution, which has received RecyClass Technology Approval and recognition from cyclos-HTP for compatibility with the polypropylene recycling stream, will be shown running on partner machinery. In parallel, various printed blister materials will be demonstrated, along with a mono-polyethylene terephthalate (PET) film, which is used in blister lidding applications for healthcare products. Together, these demonstrations give visitors a detailed look at how Constantia Flexibles’ pharmaceutical substrates perform in the precision-driven, highly regulated production environments typical of the industry
