Carton packaging industry in the coastal areas, especially in the Pearl River Delta region is a mature industry, with the most advanced production technology is the most close, carton packaging industry production scale, in the Pearl River Delta region started in early 80s, later than the mainland 10 years - 20 years. The Pearl River Delta region carton packaging industry matures in mid 90s, after fifteen years of rapid development mainly in Hong Kong, Taiwan, local entrepreneurs bold introduction of corrugated board production line and carton production line abroad, through the introduction of digestion and absorption to fully grasp the foreign advanced production technology. It can be said that the corrugated box production in the PRD has made great contributions to the production and processing technology of the whole carton in our country. The Yangtze River Delta region started earlier, and the real development was later than the Pearl River Delta. As a result of drawing on the successful development experience of the Pearl River Delta, many detours were made. At present, the total production of corrugated box packaging industry in the Pearl River Delta and the Yangtze River delta accounts for more than 60% of the country's carton packaging, and production technology is relatively leading. In the middle and late 90s, with the successful development of laser engraving technology, corrugated boxes, packaging plates, laser engraving technology gradually applied. In fact, corrugated carton packaging is divided into two categories, one is the sale of packaging, and the other is transport packaging. Sales packaging generally belongs to the inner packing, which should be met with the consumer during the sales process, such as toothpaste, soap, cigarettes (one package and one package). Transport packaging generally belongs to the packaging, such as: the packaging of toothpaste, soap, cigarette case, basically do not meet the consumer in the sales process, its main function is convenient for storage and transportation. In addition, color TV, refrigerator, air conditioning electric cooker is between the two transport packaging is packaging, printing requirements in about 60 lines, transport packaging generally in about 40 lines, the sales package in more than 80 line belongs to the color printing. According to relevant departments statistics, more than 90% of our cartons are transport packaging, most of the use of carton printing equipment production. Laser engraving machine is the world's high-tech products, products, light, mechanical and electrical integration, high technology content. Laser engraving has high efficiency, quick, precise and clear automatic engraving function. A laser engraving machine output power of only 900W, practice has proved that laser plus energy saving processing, environmental protection processing. Automatic laser engraving, can reach 40 - 60 line line printing effect, manual plate in the 40 line. Laser engraving plate completely replaces manual engraving and plate making. Due to the low cost of laser engraving, only resin version cost 1/4. At present, the carton industry generally use laser engraving plate and resin version, for corrugated box packaging printing plate. More laser processing equipment is used in the market, and the resin version is made of BASF and TDR plates. Now the laser engraving plate and manual engraving plate, resin version of a contrast analysis, for the vast number of friends in the industry reference.
At present, in the Pearl River Delta, Yangtze River Delta economic developed area, photosensitive resin plate, laser engraving is popular, 30% market share of transport packaging printing, laser engraving and fully accept the original hand engraving occupy 70% of the market. Corrugated box 90% belong to the transport packaging, printing requirements are generally in about 40 lines, and the carton printing machinery can reach up to 80 line, more than 80 commonly used color printing line. Electronic packaging, which covers electrical packaging between transportation, packaging and distribution, is available in laser engraving, and is now used mostly in resin versions for some manufacturers and operators. Competition and prediction of low energy consumption, environmental protection and laser engraving plate and photosensitive resin plate.
In the transportation, packaging and sale of packaging between the electrical and food packaging applications, the use of laser engraving plate, in addition to economic reasons, but more importantly, environmental protection. In carton packing printing practice, printing by air or high elasticity sponge pad printing, can obtain high resolution, can improve the printing effect of 10 line 20 line. At present, many carton packaging enterprises try this method to achieve better results. More robust approach is, on these basis, for a number of smaller text patterns using resin version, more than seven characters, text patterns using laser engraving plate. Examples: Zhuhai Doumen Chiba paper products company limited on the use of this method in the system of GREE air conditioning export carton, in addition to 7 words following text patterns using resin version, all using laser engraving. Thus reducing the cost of plate making under the condition of guaranteeing quality. If all of the use of photosensitive resin plate, a plate of not less than two, three thousand yuan, while the use of laser engraving, supplemented by a photosensitive resin plate, the plate is only more than 500 yuan, the enterprise to reduce the cost of production, should pay attention to the environmental is more valuable. Diversified competition in plate making technology. Competition not only provides more choice for the carton packaging industry, but also greatly reduces costs and improves the economic benefits for the carton packaging industry. Before the laser engraving plate came out, the average price of photosensitive resin was 5 yuan / in2. At that time, the Pearl River Delta almost every industrial zone has a photosensitive resin plate production and processing, but also has spread trend. Laser engraving market, imprints of abrupt drop the price fell to 1.25 yuan / in2, today the production scale also will shrink. The benefits of plate making competition to the carton packaging industry are obvious. To sum up, in the future, corrugated carton packaging enterprises in the printing plate technology competition will continue, laser engraving plate and photosensitive resin version contention will continue, and will be more intense. According to the corrugated carton packaging industry experts predict: the future in the transport packaging carton printing, photosensitive resin will completely withdraw, ranging from transportation and sales packaging printing, photosensitive resin plate or the upper hand, about 60% using the photosensitive resin plate 40% using laser engraving, the original reason imprints of monopolized situation, no doubt has become history. At present, the corrugated packaging industry is on the whole plate, laser engraving plate occupy 75% of the market share, but also the continuation of delivery extension potential, although the photosensitive resin has the advantages of high stability, high definition printing effect, but the cost is the bottleneck of its development, even if the cost can be reduced, the environmental problem is restricting the development of the key the problem. Therefore, the economic and environmental protection of laser engraving plate is the future direction of carton packaging industry
