The ongoing conflict involving Iran is sending shockwaves far beyond energy markets, with significant implications for packaging supply chains, food systems and global logistics. As oil and gas flows through the Strait of Hormuz remain constrained, the resulting surge in energy prices is beginning to reshape cost structures across multiple industries — including packaging.

Energy is a fundamental input for packaging production, particularly for plastics derived from petrochemicals. As crude oil prices rise, so too do the costs of key feedstocks such as naphtha, paraxylene and purified terephthalic acid (PTA), all essential for producing materials like PET. In Asia, especially China, these dynamics are already driving up export prices for plastic resins, with manufacturers facing a dual pressure from higher raw material costs and disrupted logistics.

The situation is further complicated by severe disruptions in global freight networks. With shipping routes through the Persian Gulf and Red Sea under strain, container availability has become highly uneven. An estimated 500,000 TEUs are stranded in the region, while congestion is increasing in alternative ports across India and Southeast Asia. This imbalance is extending transit times, increasing costs and forcing companies to rethink transportation strategies.

As a result, packaging suppliers are increasingly declaring force majeure and tightening commercial terms, including shifting toward pre-payment models. The combined effect of higher feedstock costs and freight surcharges is significantly inflating the price of packaging materials, particularly for export-oriented markets.

If oil prices were to escalate further — potentially reaching USD 200 per barrel — the impact on packaging could become even more pronounced. Analysts suggest that PET resin prices alone could increase by as much as USD 250 per tonne, with the added risk of production slowdowns or plant shutdowns due to feedstock shortages.

Beyond materials, the crisis highlights the structural vulnerability of packaging supply chains to geopolitical events. Regions heavily dependent on imported energy, such as East Asia, are particularly exposed, as disruptions in crude oil flows directly affect the availability and cost of packaging inputs.

The current crisis underscores how packaging is deeply interconnected with global energy systems, making it highly sensitive to geopolitical instability and supply chain disruptions.

In response, companies across the packaging value chain may accelerate efforts to diversify sourcing, optimise logistics and explore alternative materials. There is also growing interest in shifting certain shipments from containerised freight to breakbulk solutions, which offer greater flexibility under volatile conditions.

Ultimately, the Iran conflict is reinforcing a broader industry trend: packaging is no longer just a downstream consideration but a strategic component of global supply chains, directly influenced by energy markets, trade routes and geopolitical risk. As volatility persists, resilience and adaptability will become critical for manufacturers, converters and brand owners alike.
