Nanotechnology is being used to create new types of food packaging that can help address global food issues like hunger, food waste, and foodborne illnesses. By adding tiny particles to packaging materials, they become stronger and better at keeping food fresh. Some packaging can even release helpful substances to extend the shelf life of food. Nanotechnology is also being used to create packaging that can show if food is still safe to eat. While there are concerns about the safety of these new materials, they have the potential to greatly improve food packaging in the future.
