How Abundant Resin Masked A Fragile Supply Chain

The global resin market's long-term strategy of prioritizing low-cost, concentrated supply chains collapsed following the 2026 closure of the Strait of Hormuz. This report outlines how historical overcapacity and reliance on single-choke-point logistics left producers vulnerable, and proposes steps to build future supply resilience.

Key Takeaways

• 1.Decades of global petrochemical overcapacity created a market that, while initially efficient due to low costs, became structurally fragile to supply chain disruptions like the Strait of Hormuz closure.
• 2.The February 2026 closure of the Strait of Hormuz exposed the vulnerability of global resin supply chains, leading to price spikes and logistical constraints that will impact markets through 2026.
• 3.Packaging producers should focus on building optionality and supply security—such as qualifying alternative regional sources—rather than prioritizing the lowest short-term spot price.
