Introduction
On February 28, 2026, the Islamic Revolutionary Guard Corps of Iran announced a prohibition on any vessel transiting the Strait of Hormuz. This decision immediately triggered severe turbulence in the global energy market. As the sole maritime passage connecting the Persian Gulf to the Gulf of Oman, the Strait of Hormuz handles 25% of the world's seaborne oil trade and 20% of its liquefied natural gas (LNG) trade, with an average daily transport of approximately 20 million barrels of crude oil and refined products. The blockade of this critical waterway not only directly impacts global energy supply but also, through complex industrial chain transmission mechanisms, exerts an unprecedented shock on the takeaway plastic food box industry, which relies heavily on petrochemical raw materials.
As a vital component of the modern food service industry, the industrial chain of plastic food box products used for takeaway is highly dependent on petrochemical feedstocks. According to the latest data, polypropylene (PP) containers account for 68.4% of the global takeaway packaging market, and PP raw material prices show a strong positive correlation with crude oil prices. A $10 per barrel increase in crude oil prices raises PP production costs by approximately 400 RMB per ton. The blockade of the Strait of Hormuz not only severs a crucial oil transportation route but also disrupts the supply of petrochemical raw materials, profoundly impacting the global takeaway plastic food box industry.
This article will comprehensively analyze the impact of the Strait of Hormuz closure on businesses utilizing plastic food box solutions for takeaway, exploring dimensions such as industrial chain structure, cost transmission mechanisms, and market supply-demand dynamics. It will also discuss relevant coping strategies, providing decision-making references for industry participants.
I. The Industrial Chain Structure of Takeaway Plastic Food Boxes and the Strategic Significance of the Strait of Hormuz
1.1 Composition of the Takeaway Plastic Food Box Industrial Chain
The industrial chain for takeaway plastic food box products exhibits a characteristic of "raw materials and end-markets externally dependent, manufacturing clustered internally." It spans multiple stages from raw material supply to end-use applications. The upstream segment primarily involves petroleum refining (producing PP, PS feedstocks) and bio-fermentation (for PLA monomers), with petroleum-based plastic raw materials holding a dominant position. In 2023, China's PP production capacity reached 38 million tons, accounting for 32% of global capacity, yet still requiring substantial imports to meet demand.
The midstream manufacturing segment shows a production capacity distribution that is dense in the East and sparse in the West, with the Yangtze River Delta and Pearl River Delta regions concentrating approximately 65% of the national capacity. These manufacturers primarily use injection molding and thermoforming processes for disposable container production. Injection molding is suitable for producing structurally complex takeaway plastic food box containers, while thermoforming is better suited for thin-walled, large-area containers.
Downstream applications are highly concentrated in online food delivery platforms (accounting for about 68%), chain restaurants (18%), and commercial ready-to-eat meal channels (10%). In 2024, China's takeaway order volume surpassed 100 billion, projected to reach 120 billion by 2025. This indicates a continued surge in demand for packaging materials.
1.2 The Strategic Role of the Strait of Hormuz as an Energy Transport Hub
As the world's most critical energy transport chokepoint, the strategic importance of the Strait of Hormuz is unparalleled. According to the latest data from the U.S. Energy Information Administration (EIA), approximately 20 million barrels per day of oil were transported through the Strait of Hormuz in 2024, equivalent to about 20% of global liquid petroleum consumption. This includes 14 million barrels per day of crude oil and condensate and 6 million barrels per day of refined products.
Regarding destination, 84% of the crude oil and condensate and 83% of the LNG transiting the Strait flow to Asian markets. China, India, Japan, and South Korea are the primary destinations, together accounting for 69% of all crude oil flow through the Strait. This highly concentrated transport pattern makes Asian markets particularly vulnerable to supply disruption risks.
Crucially, the Strait of Hormuz is not only a corridor for crude oil but also a vital artery for petrochemical feedstocks. Approximately one-third of the global seaborne fertilizer trade also passes through this strait, significantly impacting the supply of raw materials for the petrochemical industry. As the world's largest plastic importer, China relies on Iranian sources for about 10% of its PE and 45% of its methanol. The blockade directly cuts off these key raw material supply channels.
1.3 Historical Blockade Events and Their Impacts
While never completely shut down, the Strait of Hormuz has experienced severe shipping disruptions. The most notable was the "Tanker War" during the Iran-Iraq War in the 1980s, where both sides attacked tankers within and near the Strait, using mines to disrupt traffic. Iran threatened to close the Strait at least three times during that period, though it remained open due to international intervention.
Similar risk events have occurred more recently. In June 2019, attacks on two tankers near the Strait of Hormuz led to a 13% short-term spike in oil prices and a tenfold surge in insurance premium rates. These historical incidents demonstrate that even localized shipping disruptions can significantly impact energy markets.
The February 28, 2026, closure event represents the most severe blockade in the history of the Strait of Hormuz. Real-time data from international oil tanker flow monitoring systems shows vessel speeds in the surrounding waters have generally dropped to zero, indicating a complete halt to shipping in the area. Major international shipping lines, including Maersk, MSC, and CMA CGM, have fully suspended services in and around the Strait of Hormuz.
II. Cost Transmission Mechanism: The Price Chain from Crude Oil to Takeaway Plastic Food Boxes
2.1 Direct Impact of Crude Oil Prices on Petrochemical Feedstocks
The closure of the Strait of Hormuz first impacts the petrochemical feedstock market through crude oil price transmission. Industry estimates suggest that a $10 per barrel increase in crude oil prices raises polypropylene (PP) production costs by approximately 400 RMB per ton. Since March 2026, oil prices have risen by $12 per barrel due to the blockade, directly pushing up the theoretical cost of PP by 480 RMB per ton.
This cost transmission mechanism exhibits significant time lags and amplification effects. Rising crude oil prices initially inflate the costs of refining feedstocks like naphtha and liquefied petroleum gas (LPG), with prices for these "chemical industry bottlenecks" surging by over 20% following the conflict. This pressure then transmits to core intermediates like ethylene and propylene – the base materials for polyethylene (PE) and polypropylene (PP), respectively – which also saw price increases exceeding 20%.
Taking PP as an example, when crude oil prices reach $90-100 per barrel, the cost of oil-based PP can approach approximately 8980-9700 RMB per ton. Given that oil-based processes account for over half of China's PP production, the impact of rising crude oil prices on PP costs is particularly pronounced.
2.2 Transmission of Petrochemical Feedstock Costs to Takeaway Container Production
In the cost structure of plastic food box manufacturing for takeaway, raw material costs constitute 65-70% of total costs, labor costs account for 15-20%, and equipment depreciation and management expenses together make up the remaining 15-20%. Substantial increases in raw material costs directly compress the profit margins of manufacturing enterprises.
The unit cost for traditional polypropylene (PP) containers is approximately 0.12-0.18 RMB, molded pulp containers range from 0.25-0.40 RMB, while PLA containers can reach as high as 0.35-0.60 RMB. Following the Strait of Hormuz closure, the rise in PP prices significantly erodes the cost advantage of traditional plastic containers, while the relative competitiveness of biodegradable materials improves.
More severely, raw material supply shortages have left many manufacturers facing a "lack of input" dilemma. China relies on imports for about 45% of its methanol, a crucial intermediate for certain plastic raw materials. The blockade has disrupted these key supplies, forcing manufacturers to seek alternative suppliers or adjust production plans, further escalating production costs.
2.3 Cascading Effects on Logistics Costs
The Strait of Hormuz blockade impacts not only raw material costs but also amplifies cost pressures through logistics channels. With shipping routes disrupted, many cargo vessels are forced to reroute around the Cape of Good Hope, adding 3,500-4,000 nautical miles to the journey and extending transit times by 10-15 days. This change in shipping routes directly leads to substantial increases in logistics costs.
Market data indicate that freight rates have surged 3-4 times following the rerouting around the Cape of Good Hope, while war risk insurance premiums have skyrocketed by 300%-500%. For instance, the freight cost for a standard container from the Persian Gulf to Asia, originally around $3,000, has risen to $12,000-$15,000 post-blockade. These additional costs are ultimately passed through to final prices, including the transportation costs for takeaway containers.
Furthermore, extended transit times necessitate increased inventory levels to ensure production continuity, thereby raising capital carrying costs and warehousing expenses. For small and medium-sized enterprises with weaker financial positions, such cost pressures can be fatal.
2.4 Cost Pass-Through Mechanisms Across the Industrial Chain
Facing cost pressures, all segments of the industrial chain are seeking ways to pass through costs. Market research suggests that a 10%-15% increase in takeaway packaging costs is transmitted to the end market through several channels:
At the petrochemical enterprise level, producers pass on cost pressures by raising ex-factory prices. In the first week of March, acrylic acid prices surged 22.26% week-on-week, while PET rose 7.40% in a single day, marking a 22.68% year-on-year increase. Chemical giant BASF announced price hikes of up to 20% for key plastic additives.
At the packaging enterprise level, given that raw materials account for over 75% of production costs, rising raw material prices directly squeeze profit margins. Many packaging companies are forced to raise product prices to survive, with ex-factory prices for takeaway plastic food box units increasing by 0.1-0.2 RMB on average.
At the restaurant business level, facing rising packaging costs, operators face a dilemma. Increasing packaging fees or meal prices could lead to order volume decline, while absorbing the costs would squeeze their own profit margins. Surveys indicate many businesses are subtly raising meal prices by 1-3 RMB or reducing discounts and promotions to compensate.

3.2 Supply-Side Capacity Changes and Supply Chain Disruption
The Strait of Hormuz blockade has severely impacted the supply side, primarily manifested in:
Raw material shortages have the most direct impact. China's dependence on Iranian imports for about 10% of its PE and 45% of its methanol has been cut off by the blockade. Concurrently, import costs for major raw materials like PP and PS have surged, forcing many small and medium-sized enterprises to reduce production or shut down due to unaffordable cost pressures.
Reduced capacity utilization. Industry data suggests capacity utilization rates for leading enterprises generally range between 75%-85%, while the average for SMEs is below 60%. Post-blockade, due to raw material shortages and cost increases, capacity utilization among SMEs has further declined, with some facing production suspension risks.
Supply chain restructuring. Facing supply disruptions, many companies are seeking alternative suppliers and adjusting supply chain layouts. Some are turning to regions like Southeast Asia or other parts of the Middle East for raw material sourcing. However, supply capacity in these regions is limited, and transportation costs have also risen sharply. Others are increasing procurement from domestic sources, but domestic capacity is also under strain.
3.3 Structural Adjustments on the Demand Side
Changes on the demand side primarily involve shifts in consumer behavior and market structure: Increased price sensitivity. The rising cost of takeaway packaging ultimately translates into higher takeaway prices for consumers. Estimates suggest packaging fees and plastic bag costs have increased by 0.2-0.5 RMB per order. For price-sensitive consumers, this could lead to reduced takeaway consumption or a shift towards lower-priced alternatives.
Growing demand for eco-friendly options. Amidst cost pressures, the relative competitiveness of biodegradable materials has improved. Although PLA containers cost 0.35-0.60 RMB, 2-3 times that of traditional PP takeout containers, the proportion of consumers willing to pay a premium for environmentally friendly packaging is increasing due to heightened environmental awareness.
Market segmentation intensifies. The high-end market is relatively less price-sensitive, placing greater emphasis on product quality and environmental attributes. Hence, biodegradable packaging is gaining faster penetration in this segment. The mid-to-low-end market remains more cost-focused, where traditional plastic packaging still dominates, albeit with a gradually shrinking market share.
3.4 Differentiated Regional Market Impacts
