New trend material for food packaging = Nanoclay!

http://nanografi.com/blog/new-trend-material-for-food-packaging-nanoclay/

Food packaging plays a vital role in preserving food throughout the distribution chain. A package provides protection, resistance, and special physical, chemical, or biological needs. In recent years, the development of novel food packaging (modified atmosphere & active packaging) has increased the shelf life of foods. Moreover, their safety and quality has increased parallely.

Nanotechnology offers several advantages to food packaging industry. For example, barrier resistance, functional performance increase with nanotechnology.

A recent trend is to use nanocomposites materials for food-packaging applications. Nanoclay is one the most popular material used in food packaging industry. Small plate-shaped particles of clay, 1nm thick and 1,000nm in diameter. These tiny partciles are embedded into the plastics normally used for packaging, such as polypropylene and polyethylene.

· It provides longer shelf life

· It improves high temperature performance

· It provides flexible packaging

· It provides several functionalty such as anti-temper, ant-microbial, self-repair sensor

· It provides good gas barrier, oxygen barrier, films

Nanotech packaging is not currently used in the most part of the Europe, but is used in the America and other parts of the world. This type of packaging could be particularly useful and advantageous in the developing world, where food spoilage is a major issue.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from: https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
