A Dutch startup, SeaWrap, has launched the world’s first mass-produced seaweed-based edible coating for fresh produce and ready meals, replacing single-use plastic cling films and trays. The plant-based material is compostable, tasteless, and extends shelf life by 3–5 days, marking a major milestone in the fight against plastic food waste.

SeaWrap’s coating is derived from sustainable kelp and red algae harvested in the North Sea. The seaweed is processed into a thin, flexible film that adheres to fruits, vegetables, and deli items without adhesives. Unlike plastic, it breaks down in home compost within 6 weeks and leaves no microplastics or toxic residues.

Dutch supermarket chain Albert Heijn has begun rolling out SeaWrap coatings for avocados, berries, and pre-cut vegetables in all 1,000+ stores. German retailer REWE and French group Carrefour are conducting national trials for fresh meat and cheese. Fast-food giant McDonald’s is testing SeaWrap-wrapped burgers in select European locations to replace plastic clamshells.

Lab tests show SeaWrap’s oxygen and moisture barrier properties match or exceed conventional plastic films, reducing food spoilage by up to 40%. Each ton of seaweed coating replaces 2.3 tons of plastic and absorbs 1.8 tons of CO₂ during cultivation. The material is also 25% lighter than plastic, cutting logistics emissions.

The launch aligns with the EU’s PPWR (Packaging and Packaging Waste Regulation), which bans single-use plastic films for fresh produce from August 2026. A April 2026 survey by Eurostat found that 82% of European consumers prefer products in seaweed or plant-based packaging, with 68% willing to pay a 5–8% premium.

Analysts at McKinsey project that seaweed-based food packaging will capture 12% of the global biodegradable packaging market by 2030, driven by scaling production and falling costs (expected to drop 40% by 2028). Companies like Unilever and Nestlé are investing in seaweed farming partnerships to secure supply.

“Seaweed is a regenerative, zero-waste resource that turns the ocean into a solution for plastic pollution,” said SeaWrap’s CEO. “This isn’t just about replacing plastic—it’s about building a food system where packaging nourishes both people and the planet.”
