Soils are soils. Among the most hated enemy of food processing. We change shoes before entrance to processing area. Soil particles might stick to our shoes and we are carrying them in by keeping the shoes unchanged. We keep the door closed at all times. We lined every window with fine screens or we never built any. Soil particles and other contaminants are carried by wind, birds and insects.
Seeing a soil particle even on outside package is a no no but Jaime Grulan Ph.D. is literally adding soil particles on packaging. But the soils are not visible by human naked eye. Its a very thin layer thousand times thinner that human hair strand. It is composed of 70 percent montmorillonite clay ( used for making bricks and other pot works) and the rest is polymer. The technology is called nano bricks.
Some advantages of this technology:
1) Can be used for flexible electronics, scratch resistant surfaces, tires and sports items.
2) Make basketball and footballs inflated for a longer period. It is also useful for inflated plastic toys.
3) Provide exceptional oxygen barrier. Better than silicone oxide and aluminum foil.
4) Increases plastic packaging tensil strength. Some plastic material are easily broken.
5) It is completely transparent. More appealing to customers who want to see the package contents before making buying decision.
6) More environment friendly than current plastic. As stated earlier, it is 70 percent clay.
7) Make the food fresh for longer periods.
8) Microwave oven safe. Presence of aluminum foil in some packaging materials make them unsafe for microwave applications.
Grulan still plan to make improvements such as: making it more moisture resistant, able to block sunlight and has antimicrobial properties.
