The packaging sector faces a structural cost reset because the old cost model no longer holds. For years, many packaging businesses worked on the assumption that raw materials, energy and freight would fluctuate, but remain broadly manageable over time.
That balance has changed. The OECD said in its March 2026 interim outlook that escalation in the Middle East had pushed its G20 inflation projection for 2026 up to 4.0%, while the International Energy Agency said member countries released 400 million barrels from emergency reserves in March to address supply disruption stemming from the war.

Those are signs of a market shock large enough to affect industrial cost structures, not only short-term pricing.
Packaging sits close to that shock. Plastic packaging relies on petrochemical feedstocks linked to oil and gas, while glass and aluminium depend on energy-intensive production.
The U.S. Energy Information Administration says oil flows through the Strait of Hormuz averaged about 20 million barrels a day in 2024, equal to roughly 20% of global petroleum liquids consumption, and the route also handled about 20% of global LNG trade.
When disruption affects a corridor of that scale, packaging costs rise through feedstocks, fuel, power and transport at the same time.
Industry reporting suggests this is already changing how packaging markets behave. Packaging Dive said in March that higher fuel and material costs, shipping disruption and weaker consumer spending were combining to affect packaging supply chains, with plastics carrying particular exposure.
Smithers has also argued that supply chain disruption is reshaping all five major packaging material groups, forcing businesses to rethink sourcing and operations. Together, those signals point to a broader packaging sector cost reset rather than a passing spike.
Why cost inflation is becoming structural
The strongest pressure is in plastics. Plastic packaging starts with petrochemical building blocks, so higher crude, naphtha and energy costs tend to move quickly into resin prices.
FoodNavigator reported in March that tensions around the Strait of Hormuz were rapidly driving up global plastic costs and disrupting polyethylene and key packaging inputs.
Plastics Today, citing ICIS analysis, reported that 84% of Middle East polyethylene capacity depends on the Strait of Hormuz for export access, along with large volumes of methanol and ethylene glycol, a precursor for PET and other resins.
That level of concentration means disruption does not just raise prices; it changes the underlying risk profile for packaging buyers.
The effect is broader than plastics alone. The International Energy Agency notes that aluminium production is highly electricity-intensive, which makes metal packaging vulnerable when energy costs rise.
Glass production is also energy intensive, and packaging businesses that buy jars, bottles and other rigid formats face the same problem in a different form. When energy, freight and feedstock costs all rise together, the cost base of the packaging sector shifts upwards across several major substrates at once.
There is also growing evidence that the reset is affecting recycled material markets, not just virgin inputs. ICIS reported on 11 March that, while there had been no direct impact on European recycled polymer prices at that point, secondary effects from movements in related markets and underlying costs could become powerful disruptors.
That matters because many brand owners and converters now depend on recycled content to meet both regulatory and customer targets. If virgin and recycled markets begin to move together under stress, the sector loses one of its traditional buffers against raw material inflation.
How businesses are changing their cost models
One response is a move away from narrow procurement models built around lowest unit price. Packaging Europe has argued that resilience and flexibility are becoming central supply chain goals, not optional extras.
That means more businesses are reviewing supplier concentration, route dependency and contract design instead of focusing only on headline material cost. In a structural cost reset, the cheapest source on paper can become the most expensive once delay risk, freight volatility and allocation problems are taken into account.
Another response is closer management of input exposure. Berlin Packaging said in its Q1 2026 industry update that packaging raw materials were under pressure from rising energy costs, inflation and trade disruption even in a market that had begun the year with relatively stable supply.
Fastmarkets has made a similar point in its 2026 packaging outlook, saying geopolitical tension, volatile energy markets and shifting trade flows are reshaping material costs and supply chain strategy.
That is why more companies are using shorter review cycles, index-linked pricing and tighter cost tracking across resin, energy and freight.
Material strategy is changing as well. Some businesses are simplifying pack specifications, lightweighting designs or broadening the mix of approved materials and suppliers.
None of those steps removes market pressure, but they can reduce exposure to single points of failure.
ICIS’s analysis of recycled polymers suggests buyers now need to monitor virgin and recycled markets together. In practice, that pushes procurement, sustainability and operations teams closer together than before, because packaging cost control increasingly depends on cross-functional decisions rather than isolated buying choices.
What the reset means for long-term competitiveness
The long-term implication is that resilience is becoming part of cost competitiveness. The World Economic Forum reported this week that the Strait of Hormuz disruption is affecting far more than oil and gas, with impacts spreading across multiple commodity flows.
For packaging, that means future cost planning must account for external shocks that can move through energy, chemicals, freight and customer demand at the same time. A cost base shaped by stable global flows is no longer a safe default assumption.
This is why the packaging sector cost reset is likely to outlast the immediate crisis. Smithers has already framed supply chain disruption as a force reshaping packaging materials and business models across the industry.
Packaging Dive has also highlighted that the current strain reaches beyond raw material availability into consumer demand and broader operating conditions. In other words, the reset is structural because it affects how packaging is sourced, priced and planned, not just how much resin or fuel costs in a given month.
For B2B decision-makers, the lesson is clear. The most competitive packaging businesses may no longer be those with the lowest nominal input costs, but those with the best visibility across materials, energy, freight and risk.
Regional sourcing, diversified supplier networks, smarter contract structures and realistic stock strategies all carry a cost. Yet in a structurally more volatile market, those measures can protect margins better than a procurement model built only for stable times.
That is the real meaning of the packaging sector’s structural cost reset.
