Create a 'Nano' wall around fresh food

A group of scientists from Texas A & M University has recently announced a development that could put a cap on flat soda and stale crackers.

With a "Nano Brick" film composed 70 percent of clay (the rest made from various polymer materials), scientists find they coat could existing packaging and keep food fresh and flavorable for more. The film is less than 100 nanometers thick (much thinner than a human hair) and reportedly more was oxygen-tight as the Silicon oxide coatings of existing food packaging 100 times.

"This is a new," outside the box ' technology, the plastic is the superior food conservation properties of the glass, "said Grunlan of Jaime, PhD., who reported the research to a meeting of the American Chemical Society." "It will give consumers tastier, longer-lasting food and packaging food industry boost help."

The Nano bricks use Montmorillonite clay to make common ingredient brick building. Viewed under a microscope, is similar to the Nano brick also brick and mortar structure. It is this structure which the Nano bricks to strengthening existing packaging makes.

"Other sound polymer reduction (permeability) have added, but they are diminishing as our film, thousands of times", Grunlan said. "We have the most organized structure - a Nano wall - that is the source for this exceptional barrier." "This is oxygen-absorbing film really most in existence."

Manufacturers use a variety of packaging materials, currently to get food and drinks, but these materials often have disadvantages. Silicon oxide, leads although there is a barrier to oxygen, under or the Nano bricks when it comes to the preservation of food. Plastic packaging, a thin coating of, apart from the fact that un-microwaveable, used can unattractive to consumers, who want to buy their food.

Grunlan said the new coating also shows for flexible electronics, scratch-resistant surfaces, tyres and sporting goods, potentially promise inflated help to stay better basketballs and footballs.
