Plastic prices hitting four-year highs has achieved something that years of sustainability pledges and consumer pressure could not: it has made alternative packaging commercially attractive almost overnight. For FMCG brands still weighing the cost of switching, the Iran war has effectively made that decision for them.
South Korean cosmetic packaging manufacturer Yonwoo, a supplier to L’Oréal and other major multinationals, has seen inquiries for its paper-based tubes and pouches increase threefold since the conflict began disrupting oil and petrochemical flows from the Middle East. The company’s paper tubes use just 20 per cent of the plastic required by conventional packaging — a specification that was once a sustainability talking point and is now a cost argument.
What Is Driving the Plastic Price Surge
The Iran war has choked off supplies of the raw materials — oil and petrochemicals — that feed plastic production across Asia. The region is heavily exposed: China, Japan, South Korea and Southeast Asia together consumed almost a third of the world’s total plastic by 2022, according to OECD data, a figure representing a 900 per cent increase since 1990.
Japan’s position is particularly acute. The country ranks behind only the United States in plastic production and consumption per capita, according to a recent Tsinghua University study published in the science journal Nature. Japanese wholesalers are already warning of potential shortages of plastic trays and bags, with supermarket operators openly discussing contingency plans for a world without reliable plastic supply.
Mitsubishi Chemical and Sanipak, two of Japan’s major plastic bag and cling wrap manufacturers, have announced price increases of approximately 30 per cent on some products in the coming weeks, citing raw material cost pressures driven directly by the conflict.
Green Packaging Demand Triples as Plastic Costs Bite
Yonwoo’s parent company, Kolmar Korea, confirmed that initial interest in its eco-friendly range came from sustainability-focused brands. But the inquiry pipeline has since broadened significantly as plastic costs have risen. “Interest initially came from companies focused on sustainability, but if the plastics issue gets prolonged, we expect demand to further increase,” said Kim Min-sang, a senior manager at Kolmar Korea.
The shift is visible across the region. In Malaysia, dairy producer Farm Fresh has temporarily switched to paper-based milk cartons after disruptions to its plastic supply chain. Taiwan’s Lastic, which produces bamboo-based biodegradable material, lost US airline customers after Trump’s import tariffs dampened American interest last year — but has since received fresh quote requests from those same buyers as plastic prices have climbed.
“It’s not that I like to look at the upside of war, but if you can’t control it, you’ve got to find the silver lining,” said Luke Anderson, senior development manager at Lastic.
Where the Supply Chain Is Breaking Down
Not every manufacturer can pivot quickly. South Korea’s Gaone International, which produces packaging for face masks, has slashed daily output to between 10 and 20 per cent of its usual one million units as it searches for alternative suppliers. Testing new materials takes time — time that clients waiting up to eight weeks for orders simply do not have.
“I hope things return to normal as soon as possible,” said Han Kyung-hun, sales team manager at Gaone, adding that recovery could take months even if the conflict ended immediately. For brands relying on high-volume, low-margin packaging runs, that kind of disruption has direct consequences for shelf availability and production planning.
| Company | Country | Response to Plastic Disruption | Impact |
|---|---|---|---|
| Yonwoo / Kolmar Korea | South Korea | Scaling paper tube and pouch production | Inquiries up threefold |
| Farm Fresh | Malaysia | Switched to paper-based milk cartons | Temporary supply continuity |
| Lastic | Taiwan | Bamboo-based biodegradable material | US buyers returning for fresh quotes |
| Gaone International | South Korea | Hunting for new suppliers | Output cut to 10–20%, 8-week order delays |
| Mitsubishi Chemical / Sanipak | Japan | Raising prices ~30% on select products | Cost pressure passed directly to buyers |
What This Does Not Change for FMCG Operators
The shift toward alternative packaging is real, but it is largely reactive and, for many companies, temporary. Manufacturers like Gaone are not redesigning their supply chains — they are managing a crisis. Once plastic prices stabilise, the commercial incentive to revert to conventional materials will return for cost-sensitive categories.
The global treaty to tackle plastic pollution remains stalled after the US and plastic-producing nations pushed back against EU-led production caps. Without a binding regulatory framework, the structural economics of plastic — cheap, versatile, scalable — have not fundamentally changed. Price spikes driven by geopolitical disruption are not the same as a permanent cost shift.
Australian FMCG brands sourcing packaging from Asian suppliers should also note that the disruption is uneven. Categories with complex packaging requirements or long material-testing cycles face a different risk profile than those that can substitute paper or bamboo alternatives quickly.
Sustainable packaging suppliers with ready-to-scale alternatives — particularly those already qualified with major FMCG multinationals — are the clearest near-term beneficiaries. Brands that invested early in alternative packaging development now have a cost-competitive product to offer buyers who previously dismissed the premium. The timeline for commercial benefit is immediate for those with existing supply agreements, and three to six months out for those entering qualification processes now.
Green Packaging’s Structural Moment or a Temporary Window
I’ve tracked sustainability packaging trends across FMCG for years, and the pattern is familiar: interest spikes when conventional materials become expensive or scarce, then retreats when supply normalises. What’s different this time is the scale of the disruption and the speed of the inquiry surge. Threefold inquiry growth at a single supplier in a matter of weeks is not a trend — it’s a signal that procurement teams are taking alternative materials seriously at a category level, not just as a sustainability footnote.
If plastic prices remain elevated through the second half of 2026, the brands that locked in alternative packaging supply now will carry a meaningful cost and availability advantage over those that waited. The sustainability case for green packaging has not changed. The cost case just got considerably stronger.
If you’re a procurement lead or brand manager reassessing your packaging supply chain right now, the window to qualify alternative materials and lock in supplier agreements is open — but it will not stay that way if the rest of the market moves at the same pace.
