Nanotechnology is widely used in packaging

Antibacterial Packaging Materials Japan has added a new type of inorganic antibacterial agent to packaging materials. At present, antibacterial films are widely used. Pure natural base materials can exert amazing bactericidal effect under the transformation of nanotechnology. Antibacterial and aseptic packaging can denature or sediment the bacteria. Once it encounters water, it will exert greater destruction on the bacteria. The adsorption capacity and penetrating power are also very strong, and there are still strong antibacterial effects after multiple washings. The antifouling film has an efficiency of more than 98% in the barrier aerosol, and the film has excellent air permeability, barrier, and filtration properties.

Nano-preservation packaging materials can improve the fresh-keeping effect of fresh fruits and vegetables and extend the shelf life. Adding nano-silver powder to the fresh-keeping packaging material can accelerate the release of ethylene from the oxidized fruits and vegetables and reduce the ethylene content in the package, thereby achieving a good preservation effect.

Ceramics and glass containers can obtain high toughness ceramic materials or glass materials. The United Kingdom blended nano-alumina with zirconium dioxide to obtain high-toughness ceramic materials. Japan added aluminum oxide nanoparticles to ordinary glass, significantly changing the brittleness of the glass.

UV-proof packaging materials In the UV-proof packaging materials, nano-anti-UV powders are added, so that the manufactured UV-proof packaging bags can achieve good UV protection effects.

Anti-counterfeit packaging material A kind of nano-particles with characteristics such as absorption of infrared rays, large surface area and high surface activity, which are sensitive to the surrounding environment (temperature, light, humidity, etc.), are added to the packaging material, or after the coating is applied to the surface of the packaging material, When people choose commodities, they can use the temperature, light or humidity to identify them, so as to achieve the purpose of anti-counterfeiting.

Anti-Static Packaging Materials Metal nanoparticles have the special function of eliminating static electricity. As long as a small amount of metal nanoparticles is added during the production of packaging materials, electrostatic phenomena can be eliminated, so that the surface of the package will no longer absorb dust and reduce friction-induced scratches. At the same time, at the time of printing, due to the absence of electrostatic adsorption on the surface, the printing speed is high and the printing effect is good.
