Plastic squeeze lifts greener packaging

Paper tubes, cartons and bamboo-based alternatives are gaining commercial ground across Asia as the war-linked disruption to petrochemical supplies pushes plastic costs higher and leaves manufacturers, retailers and consumer brands scrambling for substitutes. What began as a supply shock tied to oil and chemical flows from the Middle East is now rippling through supermarket shelves, cosmetics counters and factory floors, giving an unexpected opening to packaging formats that use less plastic or avoid it altogether.

South Korea’s Yonwoo, which makes cosmetics packaging and supplies major brands including L’Oréal, says enquiries for its paper-based options have tripled as buyers look for ways to reduce exposure to tight plastic supply. One of its better-known offerings, a paper tube used for sunscreen and lotion products, uses only about 20% of the plastic found in conventional packaging. The shift is not purely ideological. Plastic prices have climbed to roughly four-year highs as conflict-related disruption chokes the flow of oil and petrochemical feedstocks, making alternatives that once looked niche appear commercially sensible, at least for part of the market.

Asia is especially exposed because it is both heavily dependent on Middle East feedstock and deeply tied to plastic consumption. OECD data cited by Reuters show China, Japan, South Korea and Southeast Asia together accounted for almost a third of global plastic use by 2022, a rise of about 900% from 1990. The region also generates more than a third of plastic waste leaking into the environment. Japan, meanwhile, ranks behind only the United States in plastic production and consumption per person, according to a 2025 study published in Nature by researchers from Tsinghua University. That combination of dependence, scale and waste has long made Asia central to the plastics debate; the current supply squeeze is forcing that debate into boardrooms far faster than policy negotiations managed to do.

Strain is already visible in Japan’s retail and manufacturing chain. Marutake supermarket in Saitama has been warned about possible shortages of plastic trays and bags, a sign that the pressure is moving beyond raw materials into everyday distribution. Mitsubishi Chemical and Sanipak have said they plan to raise prices by around 30% on some plastic bags and cling-wrap products in coming weeks as raw-material costs climb. Broader industrial sentiment has deteriorated as well: the Reuters Tankan poll showed Japanese manufacturers’ confidence suffered its sharpest monthly drop in more than three years in April, with chemicals among the sectors hit hardest by surging costs and procurement uncertainty.

Elsewhere in Asia, companies are making tactical pivots rather than wholesale transitions. Malaysia’s Farm Fresh has temporarily switched to paper-based milk cartons because of the disruption in plastic supply. Taiwan’s Lastic, which produces bamboo-based biodegradable material, says higher plastic prices have brought U. S. customers back for fresh quotes after trade tariffs had cooled interest. These moves suggest the market is not turning decisively away from plastic so much as repricing risk: when conventional resin is plentiful and cheap, greener formats struggle to win volume; when war, shipping disruption and feedstock shortages make plastic scarcer, alternatives suddenly look viable.

That does not mean the transition will be smooth or durable. South Korea’s Gaone International, which makes packaging for face masks, says testing alternative materials takes time and cannot be done at industrial speed without commercial risk. The company has cut output to between 10% and 20% of its usual one million units a day while it searches for new suppliers, and it is warning clients they may wait up to eight weeks for orders. Even a quick easing in the conflict would not instantly repair the system. South Korea has already moved to curb hoarding of key petrochemical feedstocks, banning inventories of seven naphtha-based chemicals from rising more than 80% above year-earlier levels through June 30, an indication of how seriously governments view the supply threat.
