Food packaging industry into the era of 'nano'

as a high and new technology industry in chaoyang technology, nanotechnology is leading the stock market, with nano in all walks of life are as an opportunity for the development of all kinds of application, so it is with the packaging industry. It is understood that the current printing and packing industry study of nanometer materials is only in forming the application of nanometer materials in the industry research and development stage. The food packaging applications *.

Beijing printing institute qi yuan sheng, director of the center for teaching practice, the current industry only belong to the category of applied research on the study of nanometer materials, the direction of the research is not the same and different institutions, a nanoscale ink research and development, such as research and development of the nanometer packaging material, even as meters of granular size of nano robot research and development.

among them, the future nanoscale packaging plastic film is considered to be in the packaging industry * first breakthrough and * promising applications. “ Nanomaterials application actually not as mysterious as people think. ” Qi yuan said, with the aid of external light, thermal chemical treatment, will the packaging material modification of nano materials, in order to achieve a higher cut off performance, is longer for food preservation, higher tensile strength and hardness, higher plasticity, and other functions, to achieve a wider application. For example, he said, more than ordinary plastic film * only a few kilograms weight of products, and nano packaging film carrying hundreds of kilograms of weight. However, in the field research was still in the stage of development, is not true of industrialization.

at present, has been a breakthrough in the field is the use of high separation performance of nanomaterials in food packaging in the field of application. According to the research and development institutions research proves that the 30 ~ 40 nano material dispersed in the resin to make film, be under 400 nm wavelength light has a strong absorption ability of ultraviolet absorption material, can be used as food sterilization bags and plastic bag * better raw materials. The nanometer material in the packaging industry * for important applications. At present, the domestic also has many research institutions and enterprises in this field. Beijing institute of printing as one of the research and development institutions of packaging materials, existing development stage results. Made of nanometer materials environmental protection film packaging of fruit, with ordinary film packaging * can reach more than 10 days of preservation time, from nano packaging plastic bags can make the fruit fresh longer, but not bad.

however, there are different voices on the market, the consumers are the pursuit of natural, environmental protection, people more and more pursuit made by edible instant fresh food. And so that can save more food packaging within means loss of food nutrition value of time is too long? If the packing bag of this kind of super long preservation time will be widely accepted consumer market? The actual application situation is not good to predict market.

at the same time, even if the prospect of packaging materials, but the effect of nano materials for packaging machinery and expensive testing equipment will be a stumbling block to its huge market application to expand.
