Could Crab Shells be the Answer to Sustainable Packaging?


Scientists at Georgia Institute of Technology have created a material derived from crab shells and tree fibers that has the potential to replace flexible plastic packaging, according to a recent article on

The article states that the new material is created by spraying multiple layers of chitin—a natural biopolymer—from crab shells and cellulose from trees in order to form a film that is similar to plastic packaging film. Once the material is fully dried the material is reportedly flexible, strong, transparent and compostable.

Researchers are still working to develop a method to produce chitin and improve the material's ability to block water vapor.
