US producers of polyethylene are increasing purchases of ethylene, a key ingredient used in manufacturing common plastics for packaging and containers. The buying surge indicates manufacturers are positioning to capitalize on export opportunities as global supplies tighten due to war-related disruptions.

The disruptions stem from ongoing conflicts involving Iran, which have created ripple effects throughout global supply chains for petrochemical products. Polyethylene is one of the world's most widely used plastics, found in everything from food packaging to industrial containers.
