Recently, the author ’s mobile phone friend circle was screened by Alibaba ’s “unmanned supermarket”. There is no salesperson or cashier, just swipe the QR code to enter the store, select the goods and take them away, and the mobile phone will automatically deduct the corresponding amount. It is understood that the goods in the store are using RFID technology. Electronic tags are affixed to the articles and can be sensed when passing through the area of the reader. At present, although the penetration rate of "unmanned supermarkets" is still low, the use of RFID technology in supermarket products has promoted the development of smart packaging. Reflected from the side, smart packaging will become a development trend in the packaging industry in the future.

As the saying goes, "People rely on clothes and saddles." Appearance packaging is very important for various industries, and of course the food packaging industry is no exception. With the arrival of the concept of Industry 4.0, product packaging is gradually developing towards high-end, so smart packaging has also emerged as the times require. Recently, companies such as Shenzhen Jinjia Color Printing and Meiyingsen (002303) have announced their entry into the field of smart packaging, and predict that the smart packaging market space will reach trillions. At present, the technology used in smart packaging is RFID technology, which can identify multiple electronic tags at the same time, and the operation is fast and convenient. There is a variable data barcode, and smart label QR code is also a technology widely used in smart packaging. Intelligent packaging intelligence mainly reflects three aspects. We take food packaging as an example. On the one hand, it can detect the environmental conditions of packaged food. On the other hand, it can provide information about the quality of food packaging during circulation and storage. , To maximize the protection of consumer rights and interests, to achieve product traceability. As a new industry, smart packaging has developed rapidly abroad and its applications are also widely used. However, China's development is still immature and is still in its infancy.

It is understood that there was a report in the United States on "Active and Intelligent Packaging", showing that while the population of the United States is aging, the trend of intelligent packaging is also expanding. Relevant experts predict that the market value of intelligent packaging in the United States in 2017 will reach more than 3 billion US dollars. In the next three years, its compound annual growth rate will be 8%. Among them, pharmaceutical packaging is expected to become the fastest growing application market for intelligent packaging in the United States in the next few years. Recently, Jones Packaging Company of London, Ontario, Canada has begun to "smart packaging" medicines. The introduction of an interactive "smart label" through a convenient method has changed the traditional way consumers buy medicines, especially over-the-counter medicines. The "smart tag" has built-in sensors and tracking devices that enable consumers to "talk" to the product. In addition, Finland has begun to use smart packaging technology in alcoholic products. By applying Speed Tap tags to wine bottles, remote tag management, customized content delivery, data analysis and reporting can be achieved. The most important thing is that each tag is unique, it is almost impossible to copy, and then through NFC technology, users can read the relevant information. Compared with foreign countries, China's smart packaging technology and applications are relatively mature in terms of modified atmosphere packaging and aroma release packaging, but the technical content is not high. The application and popularization of smart packaging technology as a whole will take time.

The future development trend of smart packaging and the huge potential market indicate that this industry is expected to become a new growth point for China's economic development, and will also lead the packaging industry to develop in an intelligent direction, especially the food packaging industry. At present, China's food packaging industry has basically realized automation, such as the application of automatic packaging machines, but intelligent packaging has not yet gained popularity. Compared with foreign countries, the application of smart packaging technology in China is still very low. They all say, "People go high, and water flows low." The packaging industry has always been pursuing new intelligent packaging machinery with high technological content, high degree of automation and high production efficiency. With this, I hope that packaging machinery companies can seize this development opportunity, accelerate the pace of scientific and technological research and development, and promote the development of intelligent food packaging in China, so that intelligent packaging can enter consumers' lives at an early date, and realize real-time consumer and product "dialogue".
