Source summary
RKW’s 2024 sustainability report describes thermally laminated film-and-nonwoven backsheets, including adult-incontinence applications, on page 7. It says the process avoids adhesive in that lamination step.
Against its previous products, RKW reports thickness reductions exceeding 30% for breathable versions and 40% for non-breathable versions. These are supplier comparisons of backsheet materials, not reductions in whole-diaper thickness or environmental impact.
The report was announced on August 22, 2025. This introduces the dated report, rather than a new 2026 product. A later report’s publication does not establish that the older figures remain current specifications.
