Plastic Resin Prices.

As of late March 2026, plastic resin prices are experiencing a sharp upward surge due to significant supply chain disruptions and rising energy costs. Commodity resins such as Polyethylene (PE) and Polypropylene (PP) have seen contract prices jump by as much as $0.10 to $0.11 per pound in March alone, with even larger increases announced for April.

Market analysts attribute the current volatility to geopolitical conflicts in the Middle East, specifically the closure of the Strait of Hormuz, which has choked off global supplies of oil and gas.

Polyethylene (PE): Contract prices increased by $0.10/lb in March. Major producers like Dow Inc. have already announced a further $0.30/lb hike effective April 1, 2026, while LyondellBasell is seeking a total increase of $0.35/lb through May.
