Stretch Film, PP Strapping & OPP Tape:
Japan's Packaging Materials Crisis Explained
Supply Disruption · Price Surge · Outlook — As of April 16, 2026 ｜ Last Updated: April 16, 2026
The Crisis Overview — Japan's 2026 Naphtha Shock
As of April 18, 2026, Japan's packaging materials market is facing an unprecedented compound crisis. Three critical industrial materials — stretch film, PP strapping, and OPP tape — are simultaneously experiencing severe supply disruption and sharp price increases. Stretch film and PP strapping in particular have entered a state of complete shortage: imports have effectively stopped, and the only supply available is limited domestic production distributed under strict allocation (rationing) systems.
The primary trigger was the military conflict in the Middle East that began on February 28, 2026, and the de facto closure of the Strait of Hormuz. Approximately 90% of Japan's crude oil imports pass through the Strait of Hormuz, and this disruption has directly cut off Japan's access to naphtha — the upstream feedstock for virtually all petrochemical products. According to the Ministry of Economy, Trade and Industry (METI, March 24, 2026), Japan's naphtha sourcing is split roughly 40% from the Middle East, 40% domestic refining, and 20% from other regions. The loss of the Middle East supply channel has directly constrained domestic petrochemical plant operations.

How Naphtha Disruption Reaches Packaging Materials
The supply chain logic is straightforward. Naphtha, a light petroleum fraction derived from crude oil refining, is cracked at over 800°C in petrochemical plants to produce basic chemicals: ethylene, propylene, and butadiene. These are then polymerized into synthetic resins — polyethylene (PE), polypropylene (PP), and oriented polypropylene (OPP). All three packaging products covered in this report depend directly on these resins:
- Stretch film: Linear low-density polyethylene (LLDPE)
- PP strapping: Polypropylene (PP)
- OPP tape: Biaxially oriented polypropylene (OPP) film + acrylic or rubber-based adhesive
These three products sit at the very end of the naphtha → ethylene/propylene → resin → product chain, meaning upstream shortages and price surges translate directly into product-level impacts.
Crisis Timeline
The Root Problem: Loss of Domestic Production Capacity and the Gap with Government Messaging
The most critical — and most overlooked — aspect of this packaging materials crisis is the following: even if sufficient naphtha were available domestically, Japan currently lacks the manufacturing capacity to produce stretch film and PP strapping in meaningful volumes as domestic alternatives.
The Japanese government has framed its response around resolving "bottlenecks" — securing naphtha supply so that domestic ethylene plants can resume full operation and resin output can recover (METI, March 24, 2026). This framing is accurate for the upstream petrochemical level. However, the crisis facing packaging materials operates on an entirely different level — one that naphtha availability alone cannot fix.
Decades of Cost-Driven Import Dependence Created a Hollow Industry
The history of stretch film tells the story clearly. When stretch film gained widespread adoption in Japan in the mid-1990s, it was produced domestically. Prices at that time ranged from ¥1,300–2,000 per roll (500mm × 200–300m). However, as the 21st century began, domestic production progressively shifted offshore — mirroring the broader trend across the plastics industry. By 2000–2002, imported stretch film (typically 16–18μ thickness) had become dominant, with prices falling below ¥400 per roll. This competitive pressure from low-cost imports made domestic investment in production equipment economically unviable (industry records, Minamide KK).
The result: over 90% of stretch film circulating in Japan today is manufactured overseas (Asahi Sangyo survey). Domestic film forming equipment has been dramatically scaled back through years of disinvestment. PP strapping faces the same structural condition — long-term price competition from imports suppressed domestic production investment.
As of April 2026, the largest domestic stretch film producer by volume is Daika Kogyo Co., Ltd. (Daikalap brand) — yet its output represents less than 10% of total Japanese market distribution (Asahi Sangyo survey). Other domestic manufacturers have similarly limited capacity. Even if naphtha and resin were available, the film-forming equipment and factory infrastructure required to convert that resin into finished stretch film products simply does not exist at meaningful scale within Japan. Rebuilding that infrastructure would require years of capital investment — there is no rapid solution.
Why "Naphtha Fixes It" Does Not Apply to Packaging Materials
When the government speaks of clearing "bottlenecks," it refers to restarting ethylene crackers so that PE and PP resin output can increase. This is meaningful at the polymer level. But the resin must then be converted into finished products — stretch film, PP strapping — by downstream manufacturing equipment. That downstream forming capacity has been hollowed out in Japan over 20+ years of import competition.
In other words, this crisis is not simply an acute "naphtha shortage" that government procurement can solve. It is a structural consequence of two decades of manufacturing hollowing-out, triggered and exposed by geopolitical shock. This is the fundamental disconnect between government supply-side announcements and the reality experienced on the logistics floor.
From the 2000s onward, Malaysia, Thailand, China, and South Korea made massive investments in petrochemical manufacturing, producing LLDPE and PP at costs far below Japanese domestic producers. Japanese consumers and businesses — rationally — chose cheaper imported packaging materials. Domestic manufacturers, unable to earn sufficient margins to justify capital reinvestment, progressively exited the market. The rational economic choices of individual actors, accumulated over 20 years, created a structurally defenseless supply chain. The 2026 naphtha crisis has simply made that vulnerability impossible to ignore.
Stretch Film: Market Structure, Regional Supply Status & Outlook
Japan's Procurement Structure (Normal Conditions)
More than 90% of stretch film distributed in Japan is manufactured overseas, with Malaysian-origin product accounting for approximately 70% of import share (Asahi Sangyo survey). Domestic production — led by Daika Kogyo, Sekisui Jushi, and a handful of others — represents less than 10% of total supply. Even Japan's largest stretch film brand, Taikasei Kogyo (Dia Stretch), is primarily produced through overseas partner factories, including a co-development arrangement with Malaysia-headquartered SCIENTEX, one of the world's six largest film manufacturers.
Regional Supply Status by Origin (as of April 18, 2026)
Current Price Situation
Market prices have risen more than 20% year-on-year. Spot procurement commands even higher premiums. General-purpose resin transaction prices rose 30% in April versus March alone (Nikkei Shimbun, April 15, 2026). Under allocation conditions, the primary question is not price but physical availability.
Switching to Chinese-Origin Film: Key Considerations
With Malaysian, Thai, and Korean sources effectively unavailable, Chinese film is the only realistic incremental supply option. However, procurement teams should note: Chinese stretch film has lower elongation characteristics compared to Malaysian product. Using Chinese film at the same tension settings as Malaysian film risks tearing at box corners or over-compressing cardboard. Tension (pre-stretch ratio) adjustment and field testing are mandatory before full substitution. Additionally, bulk ordering of 2–3 months' stock is not feasible under current allocation conditions. If inventory building is essential, developing a Chinese import channel is the only practical path.
Prioritize maintaining relationships with existing suppliers to secure your allocation quota. Simultaneously begin Chinese-origin film quality validation — elongation testing and tension setting calibration — as an emergency backup channel. Do not rely on spot market procurement alone.
PP Strapping: Complete Shortage — Current State & Outlook
Product Overview and Supply Chain Structure
PP strapping (polypropylene strapping band) is used across logistics and distribution operations for carton sealing, bundling multiple packages, and securing pallet loads against collapse. Available in machine-grade (for automatic strapping machines) and hand-grade variants, typically 12–19mm width. The material is 100% polypropylene, giving it excellent tensile strength, water resistance, and light weight. PP resin is produced via the naphtha → propylene → polypropylene chain.
Current Supply Situation (as of April 18, 2026) — Complete Shortage
PP strapping has entered the same complete shortage state as stretch film. Imports have effectively ceased, and only limited domestic production volumes are available, distributed under strict allocation. Domestic producers including Taikasei Kogyo (Cyclone Band) and Sekisui Jushi continue operating, but the PP resin feedstock they require is itself subject to allocation at the resin level — manufacturers are receiving only 70–80% of historical supply volumes.
Major domestic petrochemical companies including Mitsubishi Chemical and Asahi Kasei are operating in a condition where producing more PP resin generates losses at current market prices. This has created an industry-wide "contraction equilibrium" where all players simultaneously restrict output — directly constraining PP strapping availability downstream.
New orders from non-established customers and incremental volume requests above historical purchase levels are being declined by both resin suppliers and strapping manufacturers. Ordering 2–3 months' worth of additional stock is not possible under current allocation conditions. If inventory building is a business necessity, sourcing Chinese-origin PP strapping through direct import is the only realistic path to incremental volume.
Price Trends
Market prices have risen approximately 20–35% year-on-year. PP resin transaction prices are up 30% versus March alone, creating continued upward pressure that is unlikely to abate before H2 2026. Spot procurement commands additional premiums above these levels.
Outlook
Asahi Kasei's President stated that naphtha procurement is "on track through June" (Jiji Press, April 15, 2026), suggesting upstream resin availability may begin recovering in H2 2026. However — as discussed in Section 2 — the structural shortage of domestic forming capacity means that product-level supply recovery will lag raw material recovery by additional months. Year-end 2026 prices are expected to remain 20–35% above prior-year levels.
Protect existing supplier relationships and confirmed allocation volumes as the top priority. Begin parallel qualification of Chinese-origin PP strapping — verify tensile strength, machine compatibility, and consistent buckle performance. Target completing field trials before June to have a validated alternative ready if allocation conditions worsen.
OPP Tape: Brand-by-Brand Analysis — 3M, Sekisui, Tesa, Okamoto, Nitto & More
Product Overview and Cost Structure
OPP (Oriented Polypropylene) tape is the dominant carton-sealing tape across Japan's logistics and e-commerce fulfillment sectors, prized for its strength, water resistance, and transparency. Products are divided by adhesive type: acrylic-based (heat-resistant, lower cost) and rubber-based (cold-resistant, higher strength and cost).
OPP tape faces cost pressure from two directions simultaneously. First, the base OPP film substrate is derived from PP resin — directly impacted by the naphtha shortage and price surge. Second, adhesive costs are rising: DIC Corporation announced price increases of over ¥100/kg for styrene-based raw materials (the basis for rubber adhesives) on March 24, 2026 — a direct cost signal for rubber-type OPP tape. Acrylic-type adhesives face parallel increases in acrylic monomer costs.
Unlike stretch film and PP strapping, however, major domestic OPP tape manufacturers continue to operate, and physical supply has not reached allocation status. OPP tape is currently the most "procurable" of the three products covered in this report — at a higher price.
Brand-by-Brand Latest Developments (as of April 18, 2026)
Overall OPP Tape Market Price Trends
Based on data from 139 OPP tape products registered with Metoree (as of March 18, 2026), market prices across standard products are showing year-on-year increases of approximately 15–30%. Rubber-type adhesive products are trending toward the higher end of this range. Multiple Japanese packaging materials distributors have issued customer notices characterizing the situation as: "combined increases in naphtha and petrochemical feedstock prices, synthetic resin raw material costs, electricity tariffs, labor costs, and freight charges have created a situation that cannot be absorbed through internal cost reduction efforts alone."
Outlook for OPP Tape
OPP tape faces compounding cost pressures from both its base film and adhesive components, suggesting further price increases of 10–20% are likely through summer 2026. European-sourced adhesive components continue to carry rerouting freight surcharges. That said, supply continuity is maintained, and OPP tape remains the most accessible of the three materials covered in this report. Procurement teams should address stretch film and PP strapping supply security first, then focus on OPP tape cost optimization.
Consolidate OPP tape purchasing through volume contracts to lock in negotiated pricing. Review thickness specifications by use case — lighter packaging can use thinner (50μ) grades, reserving heavier gauges for genuine heavy-carton applications. Consider consolidating suppliers to leverage volume pricing, as multiple small-lot purchases compound the per-unit cost impact.

Price Scenarios & Future Outlook
Direct impact phase of Hormuz closure. Stretch film and PP strapping allocation continues. No near-term recovery expected from Malaysia, Thailand, or South Korea. Chinese-origin material is the only incremental supply option. Government's non-Middle East procurement ramp-up (900,000 kL/month) begins arriving in Japan. Further price increases across all three products are expected through this period.
Asahi Kasei President indicated naphtha procurement is "on track through June" (Jiji Press, April 15, 2026). Non-Middle East alternative procurement gains traction. China's H2 2026 PE production capacity additions (~7 million tons new capacity) begin coming online, expected to improve Chinese export availability and pricing. However, the structural gap in Japanese forming capacity persists — product-level supply recovery will lag resin recovery. Prices expected to remain 20–35% above year-ago levels.
Structural supply chain diversification advances. Industry and government pressure mounts to rebuild domestic production capacity — but new film-forming or strapping extrusion facilities require multi-year investment timelines. "Pre-COVID pricing" is not expected to return. Long-term purchase contracts and naphtha-linked price formulas become industry standard. The 2026 crisis is expected to serve as a structural turning point in how Japan manages industrial supply chain resilience.

Immediate Action Guide for Procurement Teams
Secure your allocation quota: Contact existing suppliers immediately to confirm your current allocation volume. Under rationing conditions, customers without established purchasing history or those requesting incremental volume are being deprioritized or declined. Affirm your ongoing business relationship and historical purchase record urgently.
"Stockpiling 2–3 months of supply" is not feasible under current allocation constraints. If inventory building is operationally critical, developing a Chinese-origin import channel is the only realistic mechanism for incremental volume. There is no domestic alternative.
Stretch Film: Begin quality validation of Chinese-origin film immediately. The critical variable is elongation performance — Chinese film behaves differently than Malaysian film at identical tension settings. Conduct wrap testing on your actual pallet configurations and adjust pre-stretch ratios before full substitution. Document new operating parameters for machine operators.
PP Strapping: Test Chinese-origin strapping for tensile strength and machine compatibility on your specific automatic strapping equipment. Different equipment models have different band-width and stiffness tolerances.
OPP Tape: Contact 3M Japan, Sekisui, and other preferred suppliers to review Q2 and Q3 pricing. Consolidate purchase volumes for volume-pricing negotiations. Confirm January and April 2026 price revision details.
This price environment is structural, not temporary — expect elevated costs for at least 6–12 months. Begin customer price revision discussions, supported by documented evidence of naphtha/petrochemical feedstock cost increases. Preparation of supplier-side cost substantiation (market price data, manufacturer price revision notices) will strengthen negotiations.
Initiate a supply chain mapping exercise to identify all packaging materials in your procurement portfolio that are naphtha-derived. Prioritize dual-sourcing for the highest-volume or highest-criticality items.
The 2026 crisis has exposed a systemic vulnerability: over-dependence on single-origin imported materials. Key structural responses include transitioning from single-supplier to multi-supplier and multi-origin procurement models; moving from pure just-in-time inventory models toward holding a defined safety stock buffer for critical packaging materials; exploring naphtha-linked price formula mechanisms with key suppliers to create transparent, predictable cost adjustment frameworks; and engaging with industry associations on policy discussions around rebuilding domestic production capacity.
