With the continuous development of society, people pay more and more attention to the packaging of commodities, and the selection of commodities is no longer just based on conventional information, but needs to display further information of products. Under such a development trend, the original traditional packaging can no longer meet the requirements, and intelligent packaging came into being.
At present, there are a lot of product types in intelligent packaging. Among them, RFID information intelligent packaging has the largest market segment, which is mainly used for product quality monitoring, authenticity identification and anti-counterfeiting, freight tracing, etc., which is not only conducive to the industrial upgrading of all walks of life, but also conducive to the protection of people’s livelihood.
Integrating RFID and other Internet of things technologies, intelligent packaging is developing rapidly
Through the observation of the whole social environment, it can be found that there are two main reasons for the transformation of the packaging industry to the intelligent direction: on the one hand, the rapid rise of e-commerce and logistics industries; On the other hand, it is the transformation of different industries and industrial links by digitalization and intelligence. For the packaging industry, it has become a development path to inject communication technology, electronic information technology and intelligent material technology into it.
As an industry with wide coverage and huge volume, the development of the packaging industry has always been attached great importance. During the 13th Five Year Plan period, Chinese government departments launched six major projects to transform the packaging industry into intelligent packaging, safe packaging and green packaging, pointing out the future development direction of the industry.
According to the statistics of relevant departments, in 2013, the output value of the domestic packaging industry exceeded RMB100 billion, and the market scale of the intelligent packaging industry exceeded RMB100 billion for the first time in the same year. It is expected that the market scale of China’s intelligent packaging industry will exceed RMB200 billion by 2023.
Under the guidance of this trend, relevant enterprises have taken intelligent packaging as the growth point of future development. As early as the end of 2015, Jinjia Co., Ltd. clearly put forward in its development strategic plan for the next five years: the company will vigorously promote the in-depth application of Internet +, RFID sensing technology, Internet of things, big data and other technologies in the field of packaging products, strive to achieve the wide application of RFID and other technologies in the field of large packaging by 2020, and promote the intelligent upgrading of packaging products.
In 2018, Stora Enso launched a sustainable RFID tag technology: eco technology, which combines RFID with paper tags of 100% wood fiber to provide a plastic free and recyclable tag scheme. By combining RFID with paper labels, the manufacturing process becomes more flexible. Eco labels can be recycled together with paper and paperboard materials, which is very environmentally friendly.
Alidenison developed a temperature monitoring label by using NFC technology. With the help of the NFC temperature sensing label on the package, the temperature inside the package and the external ambient temperature can be monitored and recorded, and the data can be transmitted to the smart phone. At present, NFC has been highly popularized on smart phones, and the practicability of this function has been greatly improved.
RFID promotes the development of information intelligent packaging
The rapid development of China’s intelligent packaging industry has brought new development opportunities to traditional packaging and printing enterprises. In the future, with the development and deep integration of innovative technologies such as printing electronics, RFID and flexible display, especially the rapid development of RFID technology, it will bring benefits to the development of intelligent packaging and enterprises in the industry.
According to the differences in function and technology, intelligent packaging can be generally divided into three types: functional material type, functional structure type and information type, and the information type accounts for the largest proportion among the three types. With the development of science and technology and the popularization of Internet technology, RFID information-based intelligent packaging has developed most rapidly. It is a kind of packaging form mainly used to detect the safety, internal quality and product information in the process of transportation and sales.
Looking back at the evolution of intelligent packaging, we can find that the development of information-based intelligent packaging has gone through the process from one-dimensional code and two-dimensional code to the current multi-dimensional code, RFID, NFC, EPC and other high-tech. It is widely used in logistics, warehousing, anti-counterfeiting, traceability, mobile payment and other fields.
Taking the application in food safety as an example, intelligent packaging can realize the detection of food quality, identify the authenticity of products, and realize the traceability function of products, which can protect the rights and interests of consumers to a great extent. In addition, due to the high unit price of alcohol products, various means of counterfeiting emerge in endlessly, such as recycling old packaging, forging bottle bodies, bottle caps, and even anti-counterfeiting labels to the point that they can confuse the fake with the real. In this case, the advantages of RFID technology in the scene of alcohol anti-counterfeiting and tracing naturally highlight.
Intelligent packaging still has a lot of room to play in terms of function and product form
With the increasing degree of globalization, the market scope is greatly extended, and the product supply chain is also expanding. Consumers have higher and higher requirements for product quality, especially the freshness of food, the protection of precision instruments, and the safety of drugs. In this process, intelligent packaging is increasingly becoming the extension of product functions, and the carrier of various innovative technical means such as integrated printing electronics, RFID, flexible display, etc., which are applied to almost all fields and industries including electronic products, food, beverage, medicine, daily necessities, etc.
Since the 2008 Beijing Olympic Games, the government has strengthened the supervision of drugs and food, effectively promoting the use of RFID electronic labels in China, and the application of intelligent packaging in logistics, packaging, retail and other industries has also entered a high-speed growth stage.
In general, the functions of smart labels and packaging include many aspects. For example, it can track inventory, prevent goods loss, detect whether food has gone bad, identify the authenticity of wine, remind patients to take medicine on time, and become a carrier of coupons and discount promotions to interact with consumers in games. Therefore, with the development of technology, intelligent packaging still has a lot of room to play in function and product form.
