Masterpress adds in-house pouch line for paper-based flexible packaging

Masterpress has installed a Karlville Swiss pouch-making machine at its Białystok plant in Poland, bringing pouch forming in-house for the first time. The line produces pouches from material containing more than 90 percent paper and more than 95 percent bio-based content, free of PFAS and PVDC, and designed to meet PPWR recyclability and easy-opening requirements.

Why this mattersA converter-owned paper-pouch line signals a shift away from laminated flexible formats toward mono-material, PPWR-compliant structures ahead of EU deadlines.

• Machine installed in August 2026, fully operational from September 2026 at Masterpress's Białystok site
• Material contains more than 90 percent paper and more than 95 percent bio-based content
• Material is free of PFAS and PVDC and suitable for food contact
• Oxygen transmission rate below 1 cm3/m2/day and water vapour transmission rate below 1 g/m2/day under test conditions
• Material achieved Level A under the Aticelca 501 paper recyclability assessment and passed CEPI recyclability testing
• Line also converts single-layer PE and PP structures and standard laminates in two-side-seal, three-side-seal and stand-up pouch formats
