Recognizes the advantages and disadvantages of food based on "color" smart packaging attracts attention

[Chinese Packaging Network News] By observing the color change, we can know whether the food is fresh or deteriorating? At the Aseptic Packaging Industry Development Forum held in Beijing on August 19th, a “smart label” attached to the outer packaging of goods using nanotechnology attracted much attention. Through observing the process of changing from green to red, people can be intuitive. Determine whether the product is fresh or not.

According to reports, “smart tags” are based on big data that are degraded under abnormal storage and transportation conditions. They can monitor the product quality in the logistics and sales links and the temperature and time inside and outside the packaging in real time. Consumers can go from green to red. The color gradient visually identifies whether the quality of the product is fresh or deteriorating. Experts at the meeting believed that they circumvented the safety hazards existing in the current printed warranty date labels, thereby avoiding food waste.

“The market application of smart labels will track upstream and downstream of the cold chain, and overall monitoring will cover every link from production, transportation to use, and can comprehensively monitor the quality of various common perishable products such as food and beverages, pharmaceutical vaccines and cosmetics.” Li Wei, executive vice president of Beijing Haocai Technology Co., Ltd. said.

For the promotion of the technology, Wang Yuezhong, vice president and secretary-general of the China Packaging Federation, stated that strengthening scientific and technological research and development and using high-tech technology to realize intelligent packaging are important means for promoting the technological upgrading of the packaging industry in China and developing the national packaging industry. The emergence of "smart label" technology will provide strong impetus to the developing intelligent packaging industry.
