Abstract
As pharmaceutical products become increasingly sensitive and regulatory expectations continue to rise, primary packaging must deliver uncompromising safety while supporting ambitious sustainability targets. Today, performance and environmental responsibility are no longer separate objectives — they must advance together.
To address these evolving demands, Syensqo has developed innovative solutions within the Diofan® PVDC portfolio that combine ultra-high barrier protection with measurable sustainability benefits.
Diofan® Super B represents the best-in-class solution for sustainable blister films needing best-in-class protection to water vapour and oxygen. This transparent, PFAS-free technology delivers ultra-high water vapor barrier performance comparable to PCTFE and aluminum-based solutions, meeting the most stringent WVTR requirements for moisture-sensitive drugs. At the same time, it significantly lowers environmental impact. With one of the lowest Global Warming Potentials among high-barrier materials, Diofan® Super B enables significant reduction in carbon emissions per square meter of blister film compared to incumbent high-barrier alternatives.
Building on this progress, Diofan® Ultra736 is the last product launched by Syensqo and it helps further reduce the carbon footprint of pharmaceutical blister packaging. By enabling up to a 50% reduction in barrier layer thickness versus standard PVDC coatings — while maintaining equivalent protection — it lowers raw material usage and reduces the carbon footprint of a typical medium-barrier film by approximately 13%. It also provides a significant contribution to film manufacturers in reducing their operating and logistic costs.
Sustainability in pharmaceutical packaging extends beyond carbon reduction. Recyclability is a critical pillar of circularity. Recent studies demonstrate that Diofan®-coated substrates such as PET and PVC can be effectively recycled at scale, supporting both industrial and post-consumer waste streams and contributing to more circular packaging solutions.
This presentation explores how the Diofan® portfolio enables pharmaceutical companies to balance superior product protection with sustainability and economic performance — delivering high-barrier packaging solutions without compromise.
