Thermoplastic Starch (TPS) Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Thermoplastic Starch (TPS) Market Trends and Insights

Rising Demand for Biodegradable Packaging

Under the PPWR 2025/40 regulation, converters are racing against the clock to meet the 2030 deadlines for recyclability or compostability. This urgency is compressing research and development cycles and accelerating material substitutions. By blending TPS with PLA or PBAT, manufacturers can meet EN 13432 and ASTM D6400 standards, allowing brand owners to upgrade their materials without overhauling major equipment. In Germany, France, and the Netherlands, municipal organics-collection initiatives have begun accepting certified TPS films, smoothing the path for wider adoption. Major FMCG companies are on track to eliminate non-recyclable plastics by 2028, shifting their procurement focus to pouches and sachets with higher renewable content. Collectively, these developments are driving up the baseline demand for TPS packaging grades across both consumer and industrial sectors^{[1]EUROPEAN BIOPLASTICS, “Market Data and Industry Information,” European-bioplastics.org}.

Ban on Single-Use Plastics in Major Economies

National prohibitions on polyethylene checkout bags, straws, and food-service items compel rapid TPS substitutions. Canada’s regulations entered full enforcement in December 2024, sweeping food-service operators into compliance overnight. India tightened penalties in 2025, prompting domestic converters to switch to starch blends that meet local compostability norms. China’s revised Solid Waste Law levies fees on non-degradable packaging, pushing leading e-commerce firms toward TPS mailers for urban deliveries. Because starch resins can be certified under multiple regional standards, suppliers capture demand across jurisdictions that previously required separate formulations^{[2]GOVERNMENT OF CANADA, “Single-Use Plastics Prohibition Regulations,” Canada.ca}.

Brand-Owner Sustainability Pledges Beyond Regulatory Mandates

PepsiCo and Mars Wrigley have each committed to TPS-based film development, aiming to achieve science-driven carbon targets ahead of mandated deadlines. These voluntary pledges not only surpass the EU's recycled-content benchmarks but also bolster the demand for suppliers who can ensure traceability from farm to resin. In 2025, long-term offtake agreements were inked, integrating TPS volumes into packaging strategies. This move enhances the financial viability of starch expansion initiatives and reduces borrowing costs for local processors.

Shift Toward Home-Compostable E-Commerce Mailers

California's organic-waste diversion rules now embrace backyard-compostable mailers. This niche is particularly suited for TPS grades, which are coated with thin wax layers. These layers retain moisture during transit but decompose within 26 weeks after use. In 2025, both Australian and U.S. startups witnessed a surge, boasting significant sales growth. This uptick was largely driven by small merchants adopting these eco-friendly mailers to cater to environmentally-conscious consumers. Furthermore, certification logos have emerged as key marketing differentiators, establishing a formidable entry barrier against untested imports.

Moisture Sensitivity Limiting Shelf-Life

Unmodified TPS can absorb significant water within two days at high relative humidity, causing swelling and early tearing in tropical logistics chains. PBAT-rich blends lower water uptake but dilute renewable-content claims and raise cost. Surface coatings, while helpful, must remain under a small percentage of total weight to keep EN 13432 certification, adding process complexity. Consequently, TPS remains preferred for short-lived produce bags and mulch films rather than multi-month shelf-stable goods.

Inferior Mechanical Strength vs. Petro-Plastics

While TPS's tensile strength is lower than polypropylene, this disparity restricts TPS's application in stretch-wrap and shipping sacks. Although nanofiller reinforcement and specialized compatibilizer chemistry help bridge this gap, they also elevate formulation costs. Consequently, converters are compelled to thicken the film gauge, undermining the lightweighting benefits brands seek from their packaging overhauls.

Segment Analysis

By Manufacturing Type: Extrusion Dominates, Injection Gains in Healthcare

Extrusion molding held 58.17% volume in 2025, reflecting its compatibility with existing polyethylene blown-film lines and the high-throughput economics prized by converters. This route lets regional processors retrofit rather than retool, speeding market entry and anchoring standard-grade volumes that reinforce the thermoplastic starch market. Injection molding captured a smaller base but is projected to outpace at 7.89% CAGR as medical-device makers adopt TPS composites for blister packs, trays, and diagnostic housings. The willingness of hospitals to pay a quality premium insulates injection grades from the cost pressures felt in commodity film markets.

Extrusion’s cost leadership spurs capacity additions in China and India that may temper average selling prices worldwide. Yet medical-grade injection compounds demand ISO 13485 certification and tight tolerances that shield margins. Suppliers that master both processing routes can tier their portfolios, positioning standard grades for retail bags while reserving high-amylose or nanoclay-reinforced grades for healthcare. This dual strategy allows producers to defend their share as petrochemical incumbents leverage compounding assets to challenge the thermoplastic starch market.

By Application: Films Lead, Bags Accelerate on Retail Mandates

Films controlled 47.80% application volume in 2025 and remain the anchor segment because agricultural mulch, e-commerce mailers, and fresh-produce wraps all require thin-gauge, high-surface-area formats well suited to blown extrusion. Mulch adoption surged after Spain and Italy linked farm subsidies to biodegradable film use, cementing Europe’s leadership. Bags, however, are on track for the fastest growth at 8.38% CAGR, lifted by checkout-bag bans that exclude all but ASTM D6400-compliant materials. Together, these two uses safeguard baseline demand and account for more than half of the overall thermoplastic starch market size through 2031.

Technical diversification is also underway. PLA-TPS filaments for 3D printing are winning prototype packaging work for luxury brands that want novel shapes without injection tooling. Smaller but lucrative niches such as loose-fill, plant pots, and coated paper cups extend the addressable space, giving converters multiple on-ramps into the thermoplastic starch industry. Suppliers that secure certifications across these end-uses deepen customer lock-in and can command a price premium over untested imports.

By End-User Industry: Packaging Commands, Medical Surges

Packaging consumed 57.55% of TPS volume in 2025, driven by grocery bags, courier mailers, and flexible food wraps. The segment’s regulatory exposure means volumes will climb as additional states and provinces copy California’s compostable-bag rules. Medical and pharmaceuticals, although smaller, are forecast to grow at 8.90% CAGR, the highest among end-users, because hospitals target single-use plastic reductions and generic drug makers seek packaging differentiation. This shift positions specialty grades to capture premium margins and elevates the thermoplastic starch market share of medical applications by the decade’s close.

Agriculture and horticulture benefit from in-soil degradability, eliminating costly mulch retrieval. Consumer goods, ranging from cutlery to clamshells, fill compliance gaps for quick-service restaurants facing extended producer responsibility fees. Collectively, these outlets diversify revenue streams and buffer suppliers against price swings in any single sector.

Geography Analysis

Europe kept 39.82% global volume leadership in 2025 as PPWR 2025/40 and country-level levies made non-compostable packaging economically unattractive. Germany, France, and Italy pooled more than half of continental demand, underpinned by mature composting infrastructure that validates the thermoplastic starch market size leadership. The United Kingdom’s 2024 plastic packaging tax, although outside the EU, further expanded certified-compostable demand. Nordic pilots that accept TPS films in municipal organics bins remove a historic barrier and promise steady incremental growth across Scandinavia.

Asia-Pacific is the fastest-growing region at an 8.54% CAGR to 2031. China's extended producer responsibility fees target non-degradable cartons, while India's regulations on bag thickness are steering major retail chains towards starch blends. Japan's Plastic Resource Circulation Act sets a reduction target for single-use plastics by 2030, urging retailers to adopt compostable display and produce bags. In ASEAN, harmonized standards introduced in 2024 are slashing certification costs for exporters, facilitating smoother cross-border trade in TPS packaging.

North America's adoption of these trends is uneven. States like California, Washington, and Oregon have mandated compostable food serviceware, but many interior states have yet to catch up. In Canada, a nationwide ban on polyethylene checkout bags set for 2024 has spurred TPS demand among fast-food chains. Meanwhile, Mexican states initiated their own rolling bans in 2025. A notable surge in certification volume at BPI in 2025 underscores a growing acknowledgment of starch-based compliance. However, South America and the Middle-East and Africa lag, hindered by a lack of composting infrastructure and a policy emphasis on mechanical recycling rather than organic diversion.

Regulatory Landscape

Thermoplastic starch (TPS) demand is closely tied to packaging and compostability rules, as well as the test standards used to substantiate claims. In the EU, the Packaging and Packaging Waste Regulation (EU) 2025/40 (PPWR) enters full application on 12 August 2026, tightening sustainability, labeling, and compostability-related requirements for packaging placed on the market. This increases the compliance bar for TPS-based packaging formats and their labeling.

EU food-contact requirements also continue to influence resin selection and additive packages. Transitional provisions under Regulation 2025/351 (amending Regulation (EU) No 10/2011) allow certain non-compliant plastic materials and articles first placed on the market before 16 September 2026 to be sold until stocks are exhausted. Outside Europe, TPS compliance is shaped by national standards and by the need to meet widely referenced compostability specifications demanded by global brand owners and converters. In China, GB/T 33796-2025 replaced the 2017 version and updated technical requirements for TPS, including a shift toward performance-oriented controls and making biodegradability an optional requirement, which affects how domestic grades are specified and qualified for downstream conversion. For suppliers selling into multiple jurisdictions, dual alignment to EN 13432 and ASTM D6400 remains a practical pathway to support transatlantic packaging programs and reduce certification and reformulation friction across markets.

Value Chain Analysis

The TPS value chain starts with starch feedstock sourcing, followed by plasticizer supply, compounding, and downstream conversion into films, bags, and molded parts. Corn starch remains the most common global feedstock, while tapioca is important in Southeast Asia and wheat and potato starch play larger roles in Europe, creating region-specific exposure to agricultural availability and pricing. Native starch is destructured under heat and shear with plasticizers such as glycerol, sorbitol, and water, typically via extrusion, to produce TPS pellets. These are then compounded and frequently blended with biodegradable polyesters (PLA, PBAT, PCL) to improve moisture resistance and mechanical properties for packaging and other applications.

Midstream compounders and specialty producers provide tailored grades and certifications that gate access to end markets. Companies such as Rodenburg Biopolymers (Netherlands) supply starch-based compounds and services for extrusion-oriented converters, while Sunar NP (Turkiye) markets W-Natural TPS blends positioned around EN 13432 and ASTM D6400 compostability compliance. In Thailand, RosEco leverages tapioca-based feedstock to supply TPS compounds used in flexible packaging and thermoforming. Downstream, film extruders, bag makers, and injection molders convert these compounds for brand owners and institutional buyers, and qualification is increasingly tied to compostability labeling, food-contact requirements, and application-specific performance testing. Feedstock diversification, including the use of agro-industrial side streams (such as potato rejections), is an emerging lever to reduce raw-material risk and address food-versus-materials concerns while improving circularity narratives.

Market Opportunities and Future Outlook

Opportunities concentrate where regulation and infrastructure make certified compostability a procurement requirement rather than a marketing claim. Europe is the primary commercialization arena because PPWR (EU) 2025/40 moves into full application on 12 August 2026, which raises the importance of compliant labeling and verified end-of-life pathways for packaging. This regulatory anchor supports TPS blends that meet recognized compostability specifications, commonly EN 13432 in Europe and ASTM D6400 for suppliers supporting cross-border programs. It also reinforces demand for accredited testing, in-house lab capability, and multi-standard certification portfolios among TPS compounders.

Material performance and function are also widening white space beyond commodity films. Published 2026 academic work on antimicrobial TPS/polyester nanocomposites (including zinc oxide and copper oxide additives) points to an innovation track for applications where hygiene and shelf-life are critical, including medical and certain food-contact packaging formats, as long as compostability and food-contact constraints are maintained. On the supply side, Asia-Pacific offers scale and localization headroom linked to regional conversion clusters and starch availability; China has concentrated TPS activity near corn-producing provinces, supporting high-throughput compounding ecosystems that can feed film and bag capacity additions. Brand-owner programs aimed at sustainable procurement shape material selection as well. Under its PASSION 2026 management plan, Kuraray has communicated actions around increasing sustainable procurement and expanding capacity for bio-based films used in detergent and pharmaceutical packaging, highlighting how established materials companies are upgrading bio-based film supply chains that can incorporate TPS-based structures where performance and certification align.
