U.S. Polypropylene prices experienced a shift from neutral stability to mild bullish momentum in January 2026. During the first week Polypropylene prices remained unchanged amid balanced fundamentals with stable domestic production, steady imports and comfortable inventory at the Gulf Coast. The feedstock polymer-grade propylene traded in a narrow range, keeping producer margins intact, while other developments in the wider packaging sector - which is under scrutiny over recyclability and mono-material solutions as part of the US Plastics Pact - pointed to a steady underlying consumption outlook without short-term upward pressure on prices. On second week Polypropylene recorded a 1.65% gain, which was buoyed by an evident recovery in downstream demand, especially AptarGroup's upcoming amounts for pharmaceutical aerosol inhalers and vials and tightening spot supplies in rigid packaging industry. The market transitioned from a very volatile neutral formation to a somewhat positive one, although there was no drastic turnaround in freight, energy prices, or consumer confidence to offset the shift.
