Avient Corporation launched Cesa Solvent Barrier Technology for high-density polyethylene (HDPE) bottles, a non-PFAS additive that helps manufacturers to meet tightening fluorochemical regulations without retooling extrusion blow molding lines.

Avient launches Cesa Solvent Barrier Technology for HDPE bottles.

This technology serves personal care, household, home and garden, and automotive care brands that need reliable solvent containment in mono-layer HDPE packaging.

High barrier performance, non-PFAS, drop-in solution

Avient’s Cesa Solvent Barrier Technology is a solid pellet-blend additive that lets down into HDPE during standard extrusion blow molding, maintaining package integrity and product performance without the need for specialized equipment or secondary processing steps.

Validated internal lab data shows the barrier technology delivers:

• Excellent barrier performance: 2-10x reduction in weight loss vs. unmodified monolayer HDPE for a variety of reagents (mineral spirits, toluene, etc.)

• Compatibility: regrind-compatible and prescreened against 5+ reagents in Avient labs

The new blended barrier additive significantly reduces reagent permeation, which can potentially cause paneling, weight loss, poor label adhesion, and failure against U.S. Department of Transportation hazardous-materials testing under 49 CFR (title 49 of the Code of Federal Regulations).

HDPE bottles across wide range of applications

Cesa Solvent Barrier Technology is engineered for monolayer extrusion blow-molded HDPE bottles across a wide range of applications and markets, including:

• Personal care packaging: helps maintain label adhesion and bottle geometry for body washes, oils, and styling products

• Household cleaners: reduces solvent weight loss and paneling in bottles holding terpene- and citrus-based cleaning formulations

• Home and garden chemicals: supports 49 CFR hazardous-materials package testing for fertilizers, herbicides, and pest-control formulations

• Automotive care fluids: improves containment of mineral spirits and aromatic-solvent formulations, such as wheel cleaners and engine degreasers
