  • BARRIER ADDITIVE COMPOSITIONS FOR CONTAINERS
    Publication number: 20250051567
    Abstract: Exemplary barrier additive compositions have useful barrier properties. An exemplary barrier additive composition includes a nylon 6, the nylon 6 including a nylon 6/6,9 copolymer, a compatibilizer including maleic anhydride grafted polyethylene and ethylene propylene diene terpolymer (EPDM), and an optional optical tracer. The barrier additive composition can be used in containers for liquid chemicals, such as petroleum derived products. Also disclosed are polymer blends and films that include the barrier additive composition, methods of making the barrier additive composition, and methods of making containers and films that include the barrier additive composition.
