Market Segmentation Analysis:
By Source
Plant-based sources lead this segment with about 74% share in 2024. Strong adoption comes from rising demand for natural coatings that improve strength, reduce plastic use, and support compostable packaging rules. Seaweed extracts from red and brown algae help producers create uniform films with better barrier control. Animal-based sources hold a smaller role due to supply limits and higher processing needs. Growth stays steady as food brands prefer plant-derived materials for safe and clean-label packaging.
- For instance, Notpla has 10 granted patents covering its seaweed-derived coatings and films, and the company reports its seaweed sachets (used in pilots with brands such as Heinz) are made to hold between 10 and 60 millilitres; the material is stated to biodegrade in about 4–6 weeks in typical composting conditions.
By Packaging Process
Coatings dominate this segment with nearly 52% share in 2024 because manufacturers rely on seaweed-based layers to improve moisture resistance and extend product life. The process is easy to integrate into existing carton lines and supports scalable production. Antimicrobial and nanotechnology methods gain traction as brands adopt advanced film structures to control spoilage. Electro-hydrodynamic and microorganism-based approaches grow slowly due to higher setup costs and technical complexity.
- For instance, A research team at the University of Malaysia Sabah developed a carrageenan-nanocellulose–silver-nanoparticle bionanocomposite seaweed film that achieved a water vapour transmission rate (WVTR) of 5.62 g/m²·day, while also preventing mold growth on bread for 30 days.
By Application
Food applications lead this segment with about 61% share in 2024. Demand rises as retailers shift to sustainable cartons for bakery, produce, and ready-to-eat items. Seaweed coatings help reduce oxidation, maintain freshness, and improve handling strength. Beverage brands adopt these materials at a stable pace for secondary packaging. Pharmaceuticals also expand use cases, mainly in eco-safe cartons designed for dry formulations and non-reactive storage.
Key Growth Drivers
Rising Demand for Sustainable and Compostable Packaging
Global demand for eco-friendly packaging drives strong adoption of seaweed-coated cartons. Many brands shift from petroleum-based coatings to natural alternatives that offer compostability and reduced emissions. Seaweed biopolymers provide strong barrier protection for moisture, grease, and oxygen, helping companies meet sustainability goals without losing performance. Governments push stricter waste regulations, creating new market pathways for renewable materials. Large food and beverage retailers prefer seaweed coatings as these solutions meet circular-economy targets and support certification requirements for biodegradable packaging. This shift encourages investment in seaweed processing, material extraction, and coating technologies, strengthening market growth across multiple applications.
- For instance, Duni Group, in collaboration with Notpla, launched its Alga series in 2024: a range of four fully plastic-free cardboard products (a mealbox, a box, and two tray formats) coated with Notpla’s seaweed-based barrier that resists moisture and oil, yet is fully recyclable with paper/cardboard waste streams.
Expanding Use in Perishable Food and Fresh Produce Packaging
Demand rises in the food sector as seaweed-based coatings extend shelf life and reduce spoilage. Many brands look for natural coatings that avoid synthetic additives while maintaining product quality. Seaweed extracts offer antimicrobial and antioxidant benefits, making them suitable for fruits, vegetables, baked goods, and ready-to-eat items. Retailers focus on packaging solutions that reduce food waste, especially in fresh and chilled categories, which creates strong adoption opportunities. Seaweed-coated cartons help balance durability with sustainability, supporting cold-chain stability and improving handling strength. Growth accelerates as more producers adopt plant-based coatings to meet safety, shelf-life, and environmental demands.
- For instance, in a study, researchers applied a Caulerpa lentillifera (green seaweed) edible coating to tomato, red chili, eggplant, and carrot; under refrigeration, the coated tomatoes retained their firmness and appealing appearance for 7–10 days, while uncoated controls showed wilting by day 5.
Advancement in Coating Technologies and Processing Methods
Innovation in coating processes boosts market expansion as manufacturers adopt advanced methods such as nanotechnology, antimicrobial layering, and precision film-forming techniques. These technologies enhance barrier control and help tailor coatings for specific product needs, including humidity resistance, grease protection, and microbial prevention. Automated production lines also enable consistent application of seaweed solutions, improving scale and reducing defects. Research programs explore new seaweed species for stronger film properties, creating more functional and flexible coatings. Growing collaboration between material scientists, packaging companies, and food producers accelerates commercialization. As technology matures, the market benefits from higher reliability and broader application potential.
Key Trend & Opportunity
Rising Interest in Plastic-Free Packaging Alternatives
Many companies shift toward plastic-free packaging, creating strong opportunities for seaweed-coated cartons. Consumers prefer clean and natural materials, pushing brands to replace polyethylene coatings with renewable layers made from algae extracts. This trend aligns with global bans on single-use plastics and extended producer-responsibility rules. Market leaders explore hybrid coatings using seaweed blended with natural fibers to improve strength and reduce waste. E-commerce and food delivery operators also test plastic-free cartons to meet environmental commitments. As demand for regenerative materials grows, seaweed-coated cartons gain visibility as a high-impact, low-carbon alternative in mainstream packaging portfolios.
- For instance, Notpla did partner with Levy UK + Ireland, the sports and entertainment arm of Compass Group UK & Ireland. The partnership was announced in early March 2024, with Prince William visiting the Kia Oval to mark the occasion.
Growing Investments in Seaweed Farming and Biorefinery Infrastructure
Expansion of large-scale seaweed cultivation creates long-term growth opportunities for coated carton producers. Many countries support seaweed farming due to its low land use, zero freshwater requirement, and strong carbon-sequestration profile. Growing supply improves the availability of high-quality extracts and reduces manufacturing costs. Biorefineries process seaweed into carrageenan, alginate, and other biopolymers required for coating solutions. This infrastructure growth ensures stable raw-material supply and encourages wider commercial production. As governments and investors fund sustainable aquaculture, packaging companies gain more reliable access to materials needed for coating technologies.
- For instance, the company has established the world’s first large-scale mechanized tropical seaweed farm using its proprietary SeaCombine technology for automated seeding and harvesting.
Key Challenge
Limited Industrial-Scale Production and High Processing Costs
Scaling seaweed-based coatings to industrial volumes remains a major challenge. Extraction, purification, and coating processes require specialized equipment, driving higher upfront investment and slower adoption among small manufacturers. The cost of processing seaweed biopolymers remains higher than synthetic coatings, making price competitiveness difficult in mass-market segments. Variability in seaweed supply due to weather and seasonal harvesting also affects consistency. Without efficient large-scale systems, producers struggle to maintain stable pricing and uniform coating quality. This creates barriers for wider adoption in cost-sensitive sectors such as beverages and large-volume packaged foods.
Technical Limitations in Barrier Performance Compared to Conventional Coatings
Although seaweed coatings offer strong environmental benefits, they still face challenges in matching the full barrier performance of petroleum-based coatings. Humidity resistance, mechanical strength, and long-term durability may vary based on seaweed type and processing quality. High-moisture or high-fat products often require stronger barriers, limiting use in certain packaging formats. Manufacturers work to improve rigidity, water resistance, and printability through advanced formulations, but performance gaps still restrict rapid market penetration. Achieving industry-standard barrier levels remains a key technical hurdle, especially for high-shelf-life or export-oriented products.
