Selar® Barrier Resin

Barrier Resins to Keep Food Fresh

DuPont™ Selar® PA amorphous nylon barrier resins provide unique oxygen barrier properties when wet or chilled, making the resins a perfect choice for flavor-sensitive refrigerated foods and beverages.

In bottles, jars and other rigid structures, Selar® PA barrier resins offer the crystal clarity of glass, but with lower weight and better impact resistance. Selar® PA can be blended with other barrier reins like nylon 6 and EVOH to provide certain property and processing advantages.
