Plastic Resins and Materials Prices Fall to 276.3

Plastic Resins and Materials Prices fall 1.5% in September 2026 to 276.3 and up 6.5% from a year earlier. Illustrative only: if an unchanged plastic resins and materials basket costs $250,000 now and tracks this index exactly, a 6.5% year-over-year move implies $15,258 more than a year ago. This is not a measured purchasing bill.
