Potential of polymer clay nanocomposites as barrier materials

1 Potential of polymer-clay nanocomposites as barrier materials 

Light-scattering is a function of refractive and diffractive mechanisms. The particles are too small to diffract visible light. The refractive index of clay is very close to the refractive index of polymers utilized in packaging. 

For rigid-food packaging, three notable types of food, which are all very sensitive to oxygen, could benefit greatly from these composites. Ketchup currently requires either glass bottles or a five-to-seven-layer plastic bottle. 

The second is a related tomato-based food. Salsa. Most Salsa is still sold in glass containers, especially smaller containers, and in complex
