High-performance, biodegradable insulation and coolant, made from a single precursor.

Keeping medicines cold and stable.
With seaweed.

We engineer seaweed-based thermal packaging with superior insulation, extended cold retention, and full end-of-life degradability.

Our systems outperform incumbent materials in logistics efficiency and environmental impact with no performance compromise.

Zero plastic.
Drop-in ready.
Designed for
planetary boundaries.

Sealeo replaces expanded polystyrene and synthetic coolants.

Transportation of temperature-sensitive medicines, like vaccines & insulin, relies on fossil-derived outputs.

Bulky.
Non-compostable.
Thermally unreliable across global supply routes, leading to waste and avoidable loss.

Why Sealeo

  • Single use packaging, that keeps the industry’s preferred choice, and naturally decomposes in about 6 weeks after disposal.

  • Our bio-based coolant conforms closely to the payload, eliminating dead space and reducing convective heat loss. This allows for tighter thermal envelopes and less insulation material without compromising duration. By minimising both weight and volume, Sealeo enables reclassification into lower shipping brackets, where distribution costs are calculated based on dimensional (volumetric) weight.

  • Moulded to the shape and size of the medicine it protects, whether it's a single vial or multiple units. This flexibility allows tailoring the packaging to meet specific mission requirements.
