Avient launches non-PFAS solvent barrier additive for HDPE bottles in North America

Avient Corporation launched Cesa Solvent Barrier Technology, a solid pellet-blend additive for monolayer extrusion blow-molded HDPE bottles that reduces solvent permeation up to 10x versus unmodified HDPE. The non-PFAS additive runs on standard extrusion blow-molding lines without specialized equipment and is regrind-compatible. It is now available for commercial orders in North America, targeting personal care, household, home and garden, and automotive care packaging.

Key facts

Market context

High-density polyethylene is one of the most widely used packaging resins, valued for its toughness, chemical resistance and low cost, and it is commonly blow-molded into bottles for detergents, personal care products and automotive fluids. Those bottles can let aggressive solvents permeate through the wall, which has historically pushed some converters toward fluorinated barrier treatments that face growing regulatory scrutiny. Demand for alternatives therefore tracks the consumer packaged goods, household chemicals, lawn and garden, and automotive care segments, where barrier performance and regulatory compliance both matter. Additives that work on existing extrusion blow-molding lines and tolerate recycled regrind can shorten qualification timelines for converters, since they avoid new capital equipment. For resin suppliers and compounders, such products add value to commodity polyethylene and can shift specification choices away from multilayer structures or fluorinated treatments. Buyers typically weigh barrier gains, processing compatibility and recyclability when evaluating these options.
