What is Avient's new Cesa Solvent Barrier Technology and what problem does it solve?

Avient Corporation has launched Cesa Solvent Barrier Technology, a new non-PFAS additive for HDPE bottles designed to help manufacturers comply with fluorochemical regulations by reducing solvent permeation by up to ten times. It solves the problem of solvent migration in packaging without requiring modifications to existing extrusion blow-molding lines, and it is compatible with current production processes and regrind materials, supporting applications ranging from personal care to automotive fluids.

Why is the non-PFAS nature of Cesa Solvent Barrier Technology significant for HDPE packaging manufacturers?

The non-PFAS nature of Cesa Solvent Barrier Technology is significant because it enables HDPE packaging manufacturers to meet increasingly strict fluorochemical regulations—particularly those restricting or banning PFAS (per- and polyfluoroalkyl substances) due to environmental and health concerns—without overhauling their production infrastructure. Since the technology functions as an additive that delivers up to tenfold reduction in solvent permeation and integrates seamlessly into existing extrusion blow-molding lines and regrind streams, it offers a regulatory-compliant, drop-in solution that avoids capital investment, process downtime, or formulation requalification.
