Live from Hall 11 at interpack 2026, Packaging Journal is hosting a panel at the Herrmann Ultrasound booth on one of the industryâs most pressing tensions: sustainable packaging isnât decided at the concept stage â itâs decided on the production line. New materials are more sensitive, process windows are narrowing, and the demand for stable seals keeps rising.
Together with Jenny Haase (Heyne & Penke Verpackungen GmbH), Morito Ito (Fuji Machinery), Felix Bischopink (Packiro) and Micha Augenstein (Herrmann Ultraschall), the panel explores how material innovation and production reality can actually be reconciled. The central question: what still holds up when the material changes?
From mono-materials and recyclable laminates to paper-based structures, the speakers unpack what brand owners, converters, machine builders and joining-technology specialists each need from one another to make sustainable packaging robust enough for real production conditions. A particular focus lies on the role of modern joining technologies â and on why ultrasonic sealing is becoming a key enabler when traditional heat-sealing reaches its limits with sensitive, sustainable substrates.
A practical discussion involving all parties about what truly works in practice, rather than just what is stated in the specifications.
