An examination of near- and long-term pressures on packaging manufacturers—and whether the tools you’re using to manage the response are equal to the pace at which conditions are changing.

April 2026

The closure of the Strait of Hormuz — the 33-kilometer waterway through which roughly 20% of the world’s daily oil supply travels — is not just an energy story. For flexible packaging producers, folding carton and label converters, it is a direct and immediate operational threat already moving through material costs, freight rates, and production planning in real time.

Understanding what’s happening — and what the best-run operations are doing about it — can help mitigate the short and longer term challenges ahead.

Flexible Packaging: First to Feel the Shock

Much of modern packaging is, in a very real sense, bottled oil. The majority of flexible plastic packaging materials — polyethylene, polypropylene, PET, and PVC — are derived from petrochemical feedstocks: the raw materials behind the plastics, adhesives, inks, and coatings used throughout packaging. Flexible packaging is the most directly exposed segment because it depends most heavily on these materials.

When energy supply chains are disrupted, the cost of these materials increases almost immediately.  Recent reporting confirms plastic resin prices are already rising sharply due to supply disruptions and logistics uncertainty tied to the Middle East conflict.

For flexible manufacturers, this creates immediate challenges: rapid material cost shifts, reduced resin availability, longer lead times for film structures, and increased reliance on alternate suppliers. Even small changes in resin pricing can significantly impact margins. More importantly, those changes are happening faster — often between quote and production.

Label Converters: Tightly Balanced, Highly Exposed

For label converters, the impact runs directly through adhesives, face stocks, liners, coatings, and inks — inputs that rely on petrochemical supply chains. Label production depends on a tightly balanced combination of materials where even a single disruption can affect availability, performance, and cost simultaneously.

Resins — used in filmic label constructions — are experiencing significant price increases. Freight surcharges of $1,500 to $4,000 per container are increasing the landed cost of imported label materials — films, liners, and specialty components — while rerouted vessels are extending transit times by two or more weeks. FlexoTech reports that European ink and coatings organizations are monitoring rising costs and tightening supply conditions tied to ongoing disruption, adding pressure to inks, coatings, and other critical consumables.

For label converters, the challenge is not just cost — it is variability. Adhesive pricing, material availability, and delivery timelines are all becoming less predictable, increasing the risk between estimate and production in a segment where margins are already tight and turnaround expectations are high.

Folding Carton: Caught Between Materials and Energy Costs

Folding carton manufacturers are less directly exposed to petrochemical price shocks than flexible packaging or labels — but still highly sensitive to secondary disruption effects. While paperboard itself may remain relatively stable in the near term, the total cost of a carton is shaped by far more than the substrate.
Coatings, laminations, adhesives, and specialty finishes are all tied to petrochemical inputs. Even aqueous coatings and dispersion adhesives are influenced by upstream chemical markets. Finishing adds another layer of exposure: foil stamping, metallization, and specialty embellishments depend on aluminum and other materials now under pressure.

Energy is the other major factor. Folding carton production is inherently energy-intensive — printing, drying, die cutting, folding, gluing — and when oil markets tighten, energy costs rise across the entire converting process. A job estimated with stable board pricing can still lose margin if finishing, energy, or logistics shift before production begins.

The Real Operational Problem: Managing Volatility in Motion

The reach is expected to spread if the conflict drags on.  The issue isn’t just that costs are rising. It’s how quickly manufacturers can see those changes, respond, and protect margins before jobs are already in motion.

This is where the gap between connected and disconnected operations becomes costly. When substrate prices shift weekly and lead times become unpredictable, the spread between estimated and actual cost widens fast. Manufacturers relying on spreadsheets face a compounding challenge: updating pricing, re-estimating jobs, chasing suppliers, and coordinating across departments — all while conditions keep changing.

The manufacturers navigating this best share one advantage: real-time visibility. When costs shift, their systems reflect it immediately — before margins erode.

Where a Modern Packaging ERP Changes the Equation

An integrated packaging ERP doesn’t prevent the geopolitical shock. The value is that it gives manufacturers a way to respond faster and with less guesswork — closing the window between when conditions change and when the operation adjusts.

Pricelist management and real-time cost updates. When resin prices move, material costs update and push revised pricing directly into the estimating workflow. HiFlow’s AI-powered pricelist management module automates this process, flagging cost changes and propagating them across affected products and estimates without manual intervention

Margin visibility before quotes go out. In a volatile market, the most dangerous moment is sending a quote built on yesterday’s costs. HiFlow’s estimating system shows margin exposure at the job level before any quote reaches a customer — catching pricing errors before they become production losses.

Supplier tracking and procurement coordination. When a supplier reprices, extends lead times, or declares force majeure, that information needs to flow immediately into scheduling and purchasing. HiFlow’s integrated procurement module connects purchasing, estimating, and production planning — so supplier changes trigger the right downstream responses automatically rather than getting lost in email.

Production path modeling and substrate substitution. When a primary substrate becomes unavailable or cost-prohibitive, HiFlow’s estimating platform models alternate substrates and production paths instantly — showing what a substitution does to waste factors, run speeds, and final cost before the decision is made.
Inventory visibility and real-time scheduling. Knowing what’s on hand and what jobs it’s committed to becomes critical when replenishment timelines stretch. HiFlow’s warehouse management and scheduling modules provide real-time inventory visibility connected to production planning — so operations can make informed decisions about what to run, hold, or communicate before a shortage creates a crisis.

Business intelligence and analytics. Geopolitical risk has become a permanent component of supply chain planning. HiFlow’s business intelligence module gives leadership a real-time view of margin performance, cost trends, and operational exposure — the data needed to act while there’s still time, not after month-end when the damage is already done.

What This Means for Your Operation Right Now

The Hormuz disruption is still developing. Petrochemical and resin markets are likely to remain tight, with elevated prices and high volatility as the situation evolves. The risks — insurance costs, political uncertainty, rerouting premiums — will continue to pressure packaging margins for months regardless of how quickly the immediate crisis resolves.

The question worth asking now is not whether your costs are going up. They are. The question is how quickly your operation can see it, respond, and protect the margins on jobs already in the queue — and whether your tools are equal to the pace at which conditions are changing.
