According to statistics, in 2016, the total output value of China's packaging industry reached 1.9 trillion yuan, ranking second in the world. There are about 250000 packaging enterprises in China, among which there are more than 7000 Enterprises above designated size. The output value of Enterprises above designated size is 1.2 trillion yuan, and the profit is 71.5 billion yuan. By the end of the 13th five year plan, the total output value of China's packaging industry is expected to reach 2.5 trillion yuan, with an average annual growth rate of 6.79%, of which the output value of paper packaging industry will exceed 900 billion yuan.

　　Nowadays, packaging is the carrier and protector of products. With the rise of cloud computing, mobile Internet, Internet of things and other technologies, a small packaging box can not only display relevant text and picture information of built-in products, but also realize big data collection, product traceability, anti-counterfeiting and whole process tracking through mobile phone scanning, More through ar Augmented Reality and other effects to achieve interactive communication with consumers, scientific and technological innovation is leading the traditional packaging and printing industry to the road of industrial 4.0 transformation and upgrading, and the wave of packaging intelligent and environmental protection is rising.

　　Transformation and upgrading is imminent

　　"In the application field of packaging industry, consumer goods is the most widely used downstream industry, and the packaging industry is closely related to the total retail sales of social consumer goods." According to Wang Huajun, chairman of Shenzhen Yutong Packaging Technology Co., Ltd., especially in recent years, with the rise of Internet e-commerce and the accelerated pace of consumption upgrading in China, the retail sales of social consumer goods have increased rapidly. From 2013 to 2017, the annual compound growth rate of China's total retail sales of consumer goods exceeded 10%. Over the same period, the average annual compound growth rate of China's packaging industry was 16%. In the first half of 2017, the income of paper packaging enterprises above designated size increased by 14%, and the total profit increased by 14%, outperforming the total sales of social goods.

　　In terms of total amount, although China has become a big packaging country, there is a gap with developed countries in terms of variety, quality, new product R & D ability and economic benefits. Wang Huajun pointed out that on the one hand, there are some problems in China's packaging industry, such as small-scale enterprises, low-level repeated construction and low industrial concentration. At present, the intensive development trend of the industry has gradually emerged. From the perspective of industrial layout, China's packaging industry has formed three major industrial belts: Pearl River Delta with Guangdong as the center, Yangtze River Delta with Shanghai and Jiangsu and Zhejiang as the center, and Bohai rim with Beijing and Tianjin as the center. According to the list of China's top 100 printing enterprises over the years published by printing manager magazine, the number of enterprises located in the three major industrial belts among the top 100 enterprises is stable at about 70% all the year round, and their sales share is close to 80%.

　　On the other hand, China's packaging products are still lack of variety, low quality and low technology; The product structure is unreasonable, and the main high-grade packaging equipment and raw and auxiliary materials are heavily dependent on imports; The research and development funds of packaging science and technology are low, and the innovation ability is insufficient; The recycling rate of packaging waste is low. In view of the key and difficult problems that seriously restrict the development of China's packaging industry, Wang Huajun believes that it is urgent to enhance the competitiveness of packaging enterprises through technological progress, independent innovation and new product development.

　　Looking at the history of China's packaging industry, it is not difficult to find that although many enterprises achieve technological innovation and obtain economic benefits through technological transformation, technology introduction, new product development, design and manufacturing, due to the lack of long-term sustainable independent innovation ability, once the technological innovation is imitated by competitors, they will fall into trouble again. Wang Huajun pointed out that the key to promoting the development of China's packaging industry in the next few years or even longer is to form the technological innovation ability in time, improve the technological innovation mechanism rapidly, and promote the overall transformation and upgrading of the industry.

　　In order to break the bottleneck of technological innovation and establish a path of technological innovation for sustainable development, Yutong technology always adheres to the core of independent innovation. Only in 2016, the cost of R & D reached 3% of the turnover. It has also established long-term and stable industry university research cooperation with South China University of technology, Shenzhen Polytechnic and other scientific research institutes, and established a postdoctoral innovation base Shenzhen academician (expert) workstation, Shenzhen 3D printing technology engineering laboratory, CNAs testing laboratory, ISTA laboratory and other scientific research laboratories have obtained the qualifications of China paper packaging and printing materials R & D center, national high-end printing standardization innovation practice base, Shenzhen new green packaging materials engineering technology research center, etc.

　　The trend of intelligent packaging

　　In December 2016, the 13th five year development plan of China Packaging Industry issued by China Packaging Federation clearly put forward four key points for the development of packaging industry, namely, promoting the sustainable development of green packaging, promoting the in-depth development of safety packaging, promoting the rapid development of intelligent packaging, and promoting the breakthrough development of key fields. Wang Huajun believes that with the emergence of more and more new technologies, it is an inevitable trend to promote the development of the whole packaging industry in the direction of intelligence.

　　Wang Huajun further explained that the so-called intelligent packaging mainly refers to the use of two-dimensional code, ar Augmented Reality (image recognition), invisible watermark, digital watermark, dot matrix technology, RFID electronic label and other technologies to collect product information on product packaging, so as to build a big data platform of intelligent IOT, To achieve product anti-counterfeiting, traceability, mobile marketing, brand promotion and other functions.

　　In October 2017, Yutong technology, as one of the initiators, United more than 40 enterprises and institutions to establish the international printing electronics and intelligent packaging industry consortium, which is committed to promoting the development and application of international / domestic intelligent packaging industrialization. By integrating the resources of intelligent packaging industry chain and cooperating to develop typical applications of intelligent packaging, Yutong technology can promote the popularization and application of intelligent packaging Market driven and applied standards development.

　　Among them, taking the application of RFID technology as an example, RFID is a kind of radio frequency identification technology, which can identify in a long distance (30 meters). It is a relatively mature application of intelligent packaging at present. The products with RFID tags can be recognized when they pass through the area with reader. As long as the products enter the scanning area, they can instantly complete the cumulative calculation of all products synchronously. Therefore, in the "unmanned supermarket", most of the products are sold by adding RFID chips to the packaging to sense and start the background payment process.

　　Thanks to the continuous development of intelligent technology, packaging is no longer purely responsible for the single function of protecting goods, but has become a bridge between everything. The function and value of packaging industry in the information age are being repositioned“ With packaging as the carrier and by means of digital and intelligent technology, packaging visualization can be realized, which can promote the visualization and high efficiency of supply chain management. " According to Wang Huajun, in recent years, Yutong technology has been committed to the technological innovation of intelligent packaging. Through the application of intelligent and digital technical means such as QR code, AR, RFID, NFC, invisible watermark, TTI tag, intelligent sensor and Beidou global positioning, Yutong technology has collected information from multiple links of commodity circulation and built a big data platform of intelligent IOT, Make packaging become the carrier of real interconnection of everything, and constantly enhance the added value of packaging in anti-counterfeiting traceability, intelligent positioning, information decision-making, consumer experience, mobile marketing, brand promotion, cultural communication, etc., so as to lay a solid technical foundation for the visualization and efficient management of supply chain.

　　In May this year, with the assistance of Shiyan street, Bao'an District, Shenzhen, Yutong technology became the only branch venue of the 14th China (Shenzhen) International Cultural Industry Expo and Trade Fair hosted by enterprises in Bao'an District, comprehensively displaying its intelligent packaging technologies including dot matrix, visual code, invisible code, AR, NFC, including fully degradable plastics, pulp molding, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging, plastic packaging Environmental protection ink development and other environmental protection packaging products, and developed a variety of new products in the field of new packaging materials, including 3D printing, surface finishing, micro lens 3D printing, digital printing and so on, which has aroused extensive attention from all walks of life.

　　Green environmental protection to the future

　　With the improvement of national awareness of environmental protection, as well as the government, society and printing and packaging enterprises gradually pay attention to environmental protection, with the continuous deepening of scientific and technological innovation and intelligent development, green and environmental protection packaging will be the only way for printing and packaging enterprises to achieve sustainable development.

　　In December 2016, the Ministry of industry and information technology and the Ministry of Commerce clearly proposed in the guidance on accelerating the transformation and development of China's packaging industry that we should build an industrial technology innovation system around green packaging, safety packaging and intelligent packaging, and form a green production system covering the whole life cycle of packaging around clean production and green development.

　　Especially at present, due to the rapid development of logistics express industry, disposable express packaging and non degradable sealing glue are widely used, which brings a huge burden to the environment. According to statistics, in 2017, China's express business volume reached 40 billion pieces. Last year alone, the total length of the tape used for packaging and express delivery can be 425 circles around the equator of the earth. The actual recovery rate of paperboard and plastic is less than 10%, and the overall recovery rate of packaging is less than 20%. Data show that in China's mega cities, express packaging waste has accounted for 93% of the increase in domestic waste, and the number in some large cities has also reached 85% to 90%.

　　"Focusing on the core elements of green packaging, such as reduction, recycling and so on, it is an inevitable development direction for packaging users and packaging enterprises to actively adopt appropriate packaging solutions that are material saving, easy to recycle and scientific and reasonable." Wang Huajun pointed out that taking the express box as an example, the new type of environmental protection and anti-theft packaging box without adhesive tape developed by Yutong technology innovation not only does not need to seal the box with adhesive tape, but also can be easily packed in 10 seconds. The fully enclosed box design increases its bearing pressure by five times, which can effectively reduce the damage to the contents during transportation.

　　Wang Huajun said that in order to realize the sustainable development of the packaging industry, accelerating the R & D and innovation of new materials, enhancing the self innovation ability of packaging enterprises, and combining high and new technology with applicable technology to develop new products are the top priority. Since its establishment, Yutong technology has established a multi-level R & D innovation system. In terms of environmental protection packaging, the company has mature production technologies of fresh-keeping packaging and fully biodegradable plastic bags. The self-developed biodegradable express plastic bags can be completely degraded within six months after being discarded. They can be widely used in tableware, shopping bags, express packaging bags and other kinds of products. Some packaging products have been sold in fresh places of origin, fresh e-commerce, fresh packaging industry, etc Logistics is widely used in e-commerce.

　　Nano fresh-keeping carton is a case that can solve several key pain points in the process of storage and transportation of fruits and vegetables. According to Wang Huajun, the traditional foam fruit and vegetable packaging box is not only bulky, but also has its own peculiar smell, which will affect the quality of fruits and vegetables. The most important thing is that the materials used are not degradable. Yutong technology's self-developed nano fresh-keeping carton integrates nano fresh-keeping materials in the production process. This material is a kind of natural mineral with nano level treatment, and has strong physical adsorption function. It can effectively absorb ethylene and other harmful substances emitted by fruits and vegetables' respiration in the carton, so as to prolong the fresh-keeping time of fruits and vegetables, and the packaging volume is small Forming simple, can reduce transportation costs and labor costs, increase the distribution radius.

　　With the continuous deepening of technological innovation, as a leading printing and packaging enterprise in China, Yutong technology has obtained 208 patents, including 22 invention patents, 168 utility model patents, 18 design patents, and 43 national and industrial standards. Continuous change and innovation has brought the rapid development of enterprises. In 2017, Yutong technology achieved an annual revenue of 6.948 billion yuan, a year-on-year increase of 25.36%. In 2016 and 2017, Yutong technology ranked first among the "top 100 printing enterprises in China" for two consecutive years.
