Dynamic analysis of the hottest paper packaging in

Dynamic analysis of paper packaging industry

this synthesis: Farewell to lead and fire and enter light and electricity was once an image description of the technological transformation of China's printing industry. Since then, the 16 character policy of Laser Phototypesetting, electronic color separation, offset printing and binding Phototypesetting has guided China's printing industry into a new era of light and electricity. Today, we have completed the mission and task of the optical and electrical era, and are carrying out a more comprehensive and thorough technological revolution to meet the arrival of the digital era with 0 and 1 as the basic units. Perhaps, saying goodbye to lead and fire, going through light and electricity, and entering 0 and 1 is a more complete road map for the technological development and transformation of the printing industry, and it is also an image representation of our era

in the first year of the eleventh five year plan, it is of great significance for the long-term planning and strategic development of China's printing industry to review the path of printing industry technology and look forward to its development prospects and directions

I. review of the development process of printing industry technology

if the development of printing industry technology is characterized by the degree of digitization, the development of modern printing technology can be roughly divided into three main stages, namely, the analog era, the era of coexistence of analog and digital, and the digital era. These three eras basically correspond to the three stages of the title of this article, that is, the analog era corresponds to lead and fire, the era in which analog and digital coexist corresponds to light and electricity, and the digital era corresponds to 0 and 1

second, the foundation of printing industry technology is shifting

like other media technologies, printing industry technology is based on four basic elements: product processing and processing mode, presentation mode, storage mode and communication mode. These four basic elements, like the four cornerstones supporting the building of printing industry technology, determine the basic attributes and characteristics of the printing industry and industrial technology

(1) the production and processing mode changes from analog process to digital process

(2) the media changes from physical media to digital media

(3) the storage mode changes from warehouse storage to high-density digital storage mode with the improvement of technical level

(4) the transmission mode changes from traffic transportation to digital network transmission

III Printing industry technology has entered the era of cross media

if the manuscript and printed matter are regarded as the entrance and exit of the printing process, the caliber of this entrance and exit is constantly expanding, and what connects them is a constantly multiplying and growing digital resource

IV. complete market coverage

the advantages of paper media as an information carrier and the advantages of high-speed, high-quality and low-cost printing technology in mass reproduction endow printing technology with strong vitality, which makes it remain immortal after centuries of changes, the continuous emergence of new media and fierce competition. In fact, paper media has mostly become an important part of modern civilized society, which is expensive. There is a very good reason to call it paper culture

v. ctp+cip is an ultimate goal of the digitalization of printing industry technology

print is the best method to meet the needs of popularization, and it is also the key to the enduring of printing media for several centuries. Computer direct plate making technology (CTP) and computer integrated production technology (CIP) are the inevitable destination of the development of print technology, and also an important symbol of printing industry technology in the digital era

ctp technology realizes the direct conversion from digital page (digital film) to printing plate, saves the trouble of using film and supporting links in CTF technology, and is obviously superior to CTF technology in terms of efficiency, quality, cost and so on. Therefore, it is inevitable that CTP will replace CTF and become the mainstream of the next generation of printing technology

VI. digital printing technology leads the formation and development of the on-demand market.

digital printing is the best way to provide paper media products with personalized needs. It is another new space for the development of the printing industry, and it is also the key to realize on-demand printing production and services

VII. China's printing industry can provide innovative adhesive solutions to meet the short-term and long-term business development of customers. Changes in education

China's printing higher education is divided into three levels: in addition to undergraduate and graduate students, there is also college higher vocational education. Undergraduate printing education is positioned as a cross applied discipline of higher education; College higher vocational education is classified as a kind of professional education, which is more about cultivating practical and applied talents; As for the postgraduate direction, it can be said that it is a great pity that when collecting the postgraduate discipline catalogue in 1997, the printing major was not included, and there is actually no such concept in the graduate education stage. In reality, China's printing education is still a kind of printing based on traditional printing technology, rather than the so-called education in the cross media era, so we need to make some adjustments to printing education

in addition, the distribution of printing education resources is also very uneven. Colleges and universities are relatively concentrated in the Bohai rim and Yangtze River Delta, but few in the Pearl River Delta. At present, more than 30 colleges and universities across the country have opened printing majors, represented by Beijing Institute of printing, Xi'an University of technology, Wuhan University and other colleges and universities. The distribution of educational resources of these majors is very uncoordinated with the regional distribution of China's printing industry

based on the above situation, we can see that the current printing education in China mainly has the following problems: first, printing education has not established its own discipline system, so that there is no corresponding discipline foundation in the graduate stage; Second, the content of education still tends to traditional technology and industry; Third, the training and cultivation of printing engineering education is not enough, which is actually consistent with the development and situation of the industry; The fourth is the uneven distribution of educational resources and industrial development areas; The fifth is vocational education. Vocational education here is not only higher, but also secondary, which is completely incompatible with the development and needs of the industry

analysis on the development trend of packaging materials for fast moving consumer goods

since the 1990s, China's packaging industry has developed rapidly, especially in the field of fast moving consumer goods packaging, which has effectively promoted the progress of food, daily chemicals, daily necessities, medicine and other industries. At the same time, the development of these industries, in turn, has further stimulated the market demand for various packaging materials and technologies. In the face of this situation, the development of FMCG packaging materials has the following trends

trend - packaging reduction

the competition in the FMCG industry is becoming more and more fierce. Enterprises usually control costs to ensure profits, and packaging materials, as auxiliary materials of FMCG, often bear the brunt. Therefore, the cost of packaging materials is often limited to a very low level; In addition, it is also in line with the requirements of environmental protection to save the use of materials as much as possible. Therefore, on the premise of meeting the packaging function, the material will show the trend of thin and lightweight

in the plastic flexible packaging industry, there have been new raw materials that can process thinner films and are not difficult to process, such as metallocene polyolefins. The thickness of tinplate material used in canning and beverage cans in Europe is only 0 14mm, which has reached the limit thickness of materials that can be supplied by steel companies. Foreign container manufacturers are also competing to develop rigid plastic cans, hoping to replace metal containers with their advantages of light weight, easy molding and low price. Now they have made breakthroughs in several varieties, such as cooking cans, beverage polyester cans and milk polypropylene cans

trend 2 material safety

since 2005, people's consumption concept has also gradually changed, from the past requirements for general protective functions of product packaging (such as vision, smell, touch, etc.) to deeper requirements for packaging safety. With the gradual improvement of laws and regulations, FMCG enterprises have gradually increased their efforts to control the safety of their own products, have increasingly strict requirements on the hygiene and functional safety of packaging materials, and have gradually expanded the scope of protection of packaging materials. Now many customers have asked packaging material manufacturers to provide certificates of biological safety and chemical stability of packaging materials issued by authoritative departments, especially for the use of inks and adhesives. In addition, there are many restrictions on the production environment of packaging materials. For example, because the monomer after PVC decomposition is harmful to human body, the currently widely used PVC drug blister packaging is being phased out; Some foreign companies even require packaging material suppliers to provide items such as testing the sensitivity of materials to human bodies

trend 3 production efficiency

with the continuous progress of technology, a variety of new commodities and new packaging equipment continue to appear, but in general, the production concentration and automation of FMCG enterprises are constantly improving, and the packaging equipment is developing in the direction of large-scale, rapid, efficient and automated. Packaging material production enterprises must keep up with the development of forms and strive to improve the adaptability of packaging materials, Continuously research and develop materials that ensure higher production efficiency in practical applications

for example, in the packaging of some heat sensitive products such as chocolate and ice cream, low-temperature fast sealing packaging materials are gradually replacing the traditional hot pressing packaging materials. The difference between hot pressing packaging materials and hot pressing packaging materials is that special glue is used to replace the hot sealing layer, locally coated on the surface of the base material, and then extruded at room temperature. As the heat transfer time is reduced, the sealing speed is greatly improved. Generally, the speed is 8 ~ 10 times that of the hot pressing sealing material. At the same time, the odor that may be caused by the heating material is eliminated. Due to the local coating, the material is greatly saved

trend four function intellectualization

today, some traditional packaging forms and packaging materials can no longer meet the ever-changing market demand and increasingly complex circulation protection needs. The implementation requirements of packaging materials have changed from static to dynamic. New concept packaging materials and packaging technologies have emerged or are about to appear. Functional and intelligent packaging and materials will be an important research and development direction of packaging enterprises

at present, there are many functional and intelligent packaging and materials, such as some child protective packaging, anti-theft packaging, thermal and pressure-sensitive packaging materials. Japan has recently developed packaging that can quickly reduce the temperature of food heated by microwave. In addition, fresh-keeping packaging that adds antioxidants to packaging materials has also emerged. Of course, many functional and intelligent packaging materials and packaging technologies still face many new problems to be solved and scientific and technological difficulties to be overcome, but the potential market demand is still great

trend 5. Novelty of structural form

with the intensification of competition, the differences between similar products are gradually decreasing, and the homogeneity of brand use value is increasing
