Dive Summary:

• Scientists at the Department of Science and Technology-Industrial Technology Development Institute used nanotechnology to develop a new biodegradable food packaging material.
• Led by Dr. Blessie A. Basilia, the team treated clay with ions to create what they call organoclay, or nanoclay, which they then strengthened by blending with thermoplastic starch made from cornstarch. 
• The new packaging is capable of protecting food and extending its shelf life like plastic containers, but won't cause the same harm to the environment if improperly disposed of.

From the article:

... The clay-plastic blend goes through the same process and equipment in making petroleum-based plastics. The resulting product passed the migration test required for packaging films which means that the materials in the product will not contaminate the food it is in contact with. ...
