Georgia Tech scientists developed a compostable packaging film from crab shells and plants that blocks oxygen and moisture better than many plastics.
Researchers at Georgia Tech have created a biodegradable, plant-based packaging film using chitin from crab shells and cellulose from plants, inspired by a white beetle’s structure.
The material forms a dense, oxygen- and moisture-resistant barrier that outperforms many conventional plastics.
A 2024 breakthrough using citric acid to cross-link cellulose improved its resistance to humidity.
The film is renewable, compostable, and scalable via industrial roll-to-roll processes.
Patents have been filed, and industry partnerships are underway to bring the technology to market for use in food, pharmaceutical, and personal care packaging.
Científicos de Georgia Tech desarrollaron una película de embalaje compostable a partir de conchas de cangrejo y plantas que bloquea el oxígeno y la humedad mejor que muchos plásticos.
