Smart nano-plastic food packaging developed in Mexico

A group of scientists from the Center for Research in Applied Chemestry (CIQA) have developed an intelligent and enviroment-friendly plastic packaging method for food preservation.

The wrappings contain nanoparticles that provide the package with "smart" characteristics such as the release or absorption of substances to or from food, as well as labels with antimicrobial features that change color or shape depending on the food´s condition.

Saúl Sánchez Valdez, the project coordinator, said that there are different types of nanoparticles that give specific characteristics to the packaging.
