Modern paper packaging technology and its development trend
The development of China's corrugated paper box industry is inextricably linked with the development of paper industry, paper product processing industry, carton machinery industry and related industries. Many industries have formed a complete paper product packaging industry system. According to statistics, in 2008, the annual consumption of corrugated board was over 33,600 million square meters, the annual growth rate was 13.2%, and the total value of corrugated boxes was 146 billion yuan. It will take longer than the United States to become the largest corrugated packaging country in the world. The rapid growth of paper sales in China is in stark contrast to the shrinking sales in the United States and Other parts of the world.
The International Corrugated Box Association (ICCA) released the â€œGlobal Corrugated Cardboard Market Forecast Report 2006-2010â€. The report pointed out that in 2001 and 2005, the average annual growth rate of corrugated box production was 3.9%, of which, the market development in 2001 and 2002 was relatively slow, and the growth rate was rapid from 2003 to 2005, and the average annual growth rate reached 4.5%. In addition, global corrugated carton market demand increased by 247 billion square feet from 2001 to 2005.
According to ICCA's survey, the countries ranked top 15 in corrugated box production in 2005 were the United States, China, Japan, Germany, Italy, France, Spain, the United Kingdom, Belgium, India, Canada, South Korea, Mexico, Thailand, and Russia. .
It is expected that the average annual growth rate of corrugated box production will remain at around 4% from 2005 to 2010. Among these two mature markets in North America and Western Europe, the once-fade market is expected to show modest rebound. In Central and Eastern Europe, the growth rate will slow down. In most areas that are rapidly emerging, the average growth rate of corrugated box production in Asia is maintained at about 9%. In particular, the growth rates in China, Hong Kong SAR, India, and Southeast Asia and other countries and regions will further accelerate. It is estimated that from 2005 to 2010, the global demand for corrugated box will grow by 387 billion square feet, of which 54% will come from China and India.
China is already a world leader in the production of paper and board and a major consumer. In 2007, there were approximately 3,500 paper and board manufacturers in China. The total paperboard production capacity was 73.5 million tons, and the consumption was 72.9 million tons. The per capita annual consumption was 55 kg. From 2000 to 2007, the annual growth rate of production volume was 13.39%, and the average annual consumption growth was 10.72%, which was higher than the average annual growth rate of GDP of the national economy during the same period. By 2010, China's paper and board capacity plans have been increased to 90 million tons.
According to China's macroeconomic development and the development trend of the paper industry and packaging industry, it is expected that during the period from 2005 to 2015, the demand for paper and board in China will be as shown in the following table. In the next decade, corrugated packaging still has a lot of room for development.
In order to realize the sustainable development of the corrugated paper box industry, give full play to the advantages of corrugated box packaging and utilize the development space for corrugated paper packaging, corrugated paper box industry should also face up to the problems existing in the industry, understand the development trend of the carton industry in China, and clearly define the corrugated packaging industry. Direction of development.

The development of modern packaging and printing technology
With the rapid development of science and technology, packaging and printing technology has been continuously combined with emerging technologies and marginal disciplines, and innovation and breakthroughs have been made in strategic high-tech fields. There has also been the need to transfer inks or other viscous toners to printing without pressure and printing plates. New technologies on the object, such as electrostatic printing, inkjet printing, and digital printing technology. At the same time, a variety of electronic media technologies have developed rapidly. Various new technologies represented by electronic technologies, computer technologies, and smart materials have been used in pre-press information processing, printing, and post-press processing, which has enabled packaging and printing to show a new high-tech situation.
Predicting the future is a strategic and important task. The future is designed based on the "future." The digitization, diversification, integration of printing and packaging processes, digital processing networking, generalization, integration, control automation, and standardization of image sources are the general trend.
Modern packaging design market
As we all know, before the 70s of the last century was the era of productivity, there was a market for product production; in the 1980s, it was the era of sales force, and sales methods became the main link in market competition; entering the era of image power in the 1990s, the competition of commodity images To guide consumer trends.
Modern packaging design has entered a design level with a wide range of aspects and a much more complex production process than ever before. Technology, environmental protection, market demand and experience, customer psychology, corporate image, process control, cultural trends and other elements are often combined into design products, which are highly creative and can exert various functions. Packaging is the most important advertisement for the sale of goods. It is the carrier of advertising and the packaging is the product. The impression given by packaging design far exceeds the number of other forms of dissemination of impressions.
The world has become smaller and the market has become larger. With high-tech as the background, the market ON-DEMAND is an inevitable trend in the printing and packaging market, because ON-DEMAND system not only meets the interests of customers, but also will become the basis of the global electronic transmission printing and packaging network, and information highway synthesis in the 21st century. Perfect tomorrow printing package. ON-DEMAND refers to the integration of printing and packaging. Its mark is a digital printing method with no film and no printing. It is connected with the electronic prepress processing system, wide area network system and inline binding into a box system to make distance, color and short editions. Print processing still uses a completely connected approach to meet the needs of the market. For this reason, the packaging and printing industry has integrated design functions in the 21st century to create high-efficiency information and integrate technological functions for high-resolution, high-quality, high-efficiency storage, transmission and reproduction.
Packaging printing process tends to be simplified
Modern science and technology are applied to the field of packaging and printing, so that many packaging and printing processes are simplified and more scientific and rational. For example, in the past, the molding process of plastic packaging, such as extrusion, hot pressing, stamping, etc., has gradually been used in the formation of cardboard packaging, so that paper packaging cannot be used for products that cannot be packaged in the past.
The packaging and printing treatment process is more scientific and applicable, and the packaging performance and effects have undergone significant changes. For example, in the past, wax coating and film coating processes in the surface treatment of packaging have gradually been replaced by surface gluing (spray-bonding), and anti-counterfeit packaging production processes have been transformed from local printing or production to printing and production of large areas. Security. The prepress and postpress printing of the current packaging and printing, the use of computer technology, new equipment to complete the upgrading of production factors, and post-press processing technology innovations have enabled the post-press processing industry to form a new industrial structure and product structure adjustment connotation and commercial behavior in the packaging and printing industry.
Throughout the development of paper packaging printing technology has the following new features:
1. The development of single-layer materials in the direction of multi-layer materials;
2. Offset, gravure, flexo, screen printing and other printing methods coexist, flexo printing will grow fastest;
3. The development of sheet-fed paper to roll paper and stand-alone-to-line production, and the supply of complete sets of equipment;
4. Comprehensive application of various related new technologies (such as computer design, digital technology, laser processing technology and new materials, etc.) Continuously optimize the entire production system;
5. More and more restricted by increasingly stringent environmental and health standards.
In addition, paper product packaging focuses on the development of low-weight, high-strength, lightweight, high-grade paper packaging that meets the goals of standardization, serialization, multi-species, multi-substrate, and multi-use.
Modern packaging and printing machinery intelligent
The 21st century is an era of high technology. Many high technologies will be developed and applied very well. In particular, the packaging industry has always been an industry that absorbs and applies high and new technologies. Once certain new technologies and new technologies break through, they will Application and maintenance in the packaging field.
China's packaging and printing machinery industry will develop to electromechanical, intelligent, and automatic control. The technical characteristics of the future packaging machinery will tend to "three high" - high speed, high efficiency and high quality. The focus of development tends to be low energy consumption, light weight, compact structure, small footprint, high efficiency, appearance and environment adaptability to the environment and the psychological requirements of operators, and environmental protection requirements. Printing equipment will be digitalized and miniaturized, and the cost will tend to be low. Digital printing equipment can be distributed anywhere. Data printing, storage, fiber optics and microwaves will certainly replace traditional transmission systems. In the next decade, paper media printing will have a huge development along with broadband.
The development trend of foreign packaging machinery reflects the modernization of modern advanced packaging machinery and the development and application of modern high-tech special-purpose packaging machinery. New and new technologies for the packaging machinery used today and in the future include microwave technology, aerospace industry technology (thermal control bags), microelectronics technology, information processing technology, sensing technology (optoelectronics and chemistry), laser technology (cutting, anti-counterfeit) Aspects), magnetic technology, nanotechnology, biotechnology and new processing techniques, new mechanical component structures, new fiber materials, etc. These technologies have made many packaging machines more intelligent.
Packaging and printing process integration
Many new packaging technologies are based on new packaging ideas. Technologies in this area include: Packaging and Curing Technology - Curing and Drying Energy is Renewing, From Heat to Light; Packaging Cutting and Forming Technology - New Cutting and Forming Instruments; Packaging Combining with processing--packaging and processing; packaging function borrowing technology--packing function beyond packaging, value-added function; packaging function protection technology--adding preservation, sterilization, moisture-proof, anti-static, anti-odor and other functions to packaging materials Sexual ingredients. In addition, there are also packaging technologies for live products.
The U.S. Printing Technology Association announced not long ago that the 11 new technology products that emerged in the future will have a real impact on the packaging and printing industry. The 11 new technologies include: the first PDF-based high-end prepress production system; the dot technology dedicated to flexographic printing; the Polar cutting system using CIP3 workflow; offset printing rotary press; the first laser successfully used Technical system for engraving gravure cylinders; professional digital photographic technology; new drying technology (online formation at one time); new technology for printing pressure sensitive internal labels; software packages (prepress systems); scanning software systems; on-demand printing market Printing system.
Green packaging and high-tech digital
With the rising awareness of environmental protection, the global economy and industrial system is embarking on the concept of â€œzero packaging,â€ â€œsimplified packaging,â€ and â€œgreen packagingâ€ that are preceded by the packaging revolution and put into practice. Green goods and green packaging will become new. Hot spot. Green packaging is a high-tech form of packaging. From the beginning of raw materials, to the design and manufacture of packaging, and to the recycling of products, every link must be source-cut, efficient, and harmless.
The future packaging will be green packaging. The future development trend of paper packaging containers is: once formed molded paper containers will gradually replace the current die-cutting combined paper containers; deep plastic coating technology will gradually replace the past wax; composite technology becomes paper containers The development of important techniques; CAD and CAM system will greatly reduce the design and manufacturing cycle of paper packaging containers. Moreover, the boundaries between the future sales of packaging containers and transport packaging containers are gradually disappearing.
The emergence of electronic systems based on computer processing is a major turning point in the history of packaging printing. The color electronic system mainly includes image processing technology, color separation and management technology, image scanning technology, digital video technology, and image information exchange technology. Elecroc technology contains four major technologies, JDF, XML database, PDF and INTERNET. Elecroc integrates these currently hottest technologies and standards, and it is a leading technology for the future of the packaging and printing industry. In the 21st century, the digital control data CIP3 was created due to the entire digitization and process simplification of the printing and packaging process. The combination of digital printing technology and network technology will completely change the traditional printing production model. This is a kind of brand-new production method based on "digital flow + digital media/high-density storage + network transmission". It can also be said that traditional packaging printing is a production mode of "production and then sales", and digital printing is "Production after production" production mode. The digital management of the entire packaging and printing industry is in its infancy. The poor foundation is a disadvantage and an advantage. The low starting point, large space for improvement, and easy to achieve a good ratio of input to output are among the investment directions for the highest investment recovery rate in the packaging and printing industry.
Application Prospect of Nanotechnology in Packaging and Printing Field
The formation of nanotechnology and the emergence of nanomaterials are the three most active frontier research fields in the 21st century and have achieved breakthrough results. From the date of its invention, printing has gone through more than 500 years of "lead and fire" years, spent nearly 100 years of "light and electricity" time, and now entered the "number and network" era. Qian Xuesen, a renowned scientist, believes that â€œthe structure of nanometers and below and nanometers will be the focus of the next stage of scientific and technological development. It will be a technological revolution that will lead to another industrial revolution in the 21st century.â€ Almost at the same time, in the 1990s, high-fidelity printing has quietly come to us, and its network is approximately between 10Î¼m and 20Î¼m. This shows that the printed material is not far from the nano level. The worldâ€™s first gold newspaper Shenzhenâ€™s â€œChinese Eventâ€ uses nano 24k gold paper and special printing technology and is ranked as the fifth largest invention in the world.
The latest 10 nanotechnology applications in the field of paper packaging in China and its industrialization prospects: nano-water ink, nano uv light oil and nano-pigment ink; nano spot hologram anti-fake packaging label (CI imaging anti-counterfeiting mark new technology); nano-ceramics Coating technology and nano-tungsten carbide-cobalt-based hard alloy corrugating rollers and tools, wear-resistant parts; Nano-coated fresh-keeping waterproof coating materials; Nano-scale organic and inorganic antimicrobial aseptic packaging technology; Nano-sensitive resin plate, nano-PS version Nano-structured nano-paper and paperboard (binary synergistic nano-interface material); nano-miniature sensor and nano-magnetic switch (micro-electronic control system); nano "universal adhesive" (nano sealant); nano-powder Microparticles and their modification technologies improve new materials such as high-performance packaging boxes. There are already dozens of companies in China that have applied nanotechnology to realize the industrialization of nano packaging, which indicates that the application of nanotechnology in the packaging field has entered a new stage.
