Mujō’s packaging materials are 100% biobased and chemically unmodified, making them an environmentally friendly alternative to traditional plastic. They are also biodegradable in home composting systems, ensuring minimal impact on the environment after use.

This unique material has impressive properties, including excellent fat resistance, a strong oxygen barrier, and water insolubility. These qualities make it suitable for a wide range of applications, from packaging to more complex uses. It can be customised in various forms, ranging from smooth, transparent, and glossy—reminiscent of conventional plastic—to matte, coloured, and opaque.

At the core of this material is alginate, derived from brown seaweed, which is found in oceans worldwide. Brown seaweed grows 20 times faster than trees, sequestering vast amounts of CO₂ while simultaneously helping to clean ocean water. This makes the material not only a sustainable choice but also one that contributes to the health of the planet.

Mujō’s artisanal manufacturing process currently allows for meticulous refinement and ensures the highest quality while efforts are underway to scale production for continuous, efficient manufacturing. This approach maintains precision in the early stages of development while supporting the transition to large-scale production.
