Brief analysis on the demand and printing of corrugated boxes

with the development of the commodity market, the demand for corrugated boxes is increasing year by year. The national carton sales volume was 8 billion square meters in 1996, increased to 125 billion square meters in 2000, and reached 20 billion square meters in 2002, with a 71.5-fold increase in six years

due to the improvement of people's consumption level and the further development of the retail market, it is estimated that China's annual consumption of paper and paperboard will reach 50million tons by 2005, including 15million tons of corrugated paperboard. According to the estimation of relevant experts, there will be a gap of nearly 1million tons by 2005, so the import volume of high-strength corrugated base paper will continue to grow in the near future. According to the market demand, it is a major trend for domestic high-strength corrugated base paper to develop in the direction of low quantity, high strength and full specification. The demand for medium and high strength corrugated base paper is large, and the price of corrugated base paper will rise. At present, reducing cost and reducing quantity are the two major themes of the development of corrugated base paper. In recent years, there have been F, N and G-type corrugations in the market, which are much lower than the traditional corrugations. In this way, the paperboard that confirms whether the number converted is 1 or 0 bit by bit must use low quantity corrugated base paper. At present, there are 90~l15g/M corrugated base paper, and it is expected that 60~90g/m2 corrugated base paper will be produced in the future. Therefore, the quantity of corrugated board, such as the stretching of monofilament in the second stage processing process, will be reduced from the original 1000 ~ 1100g/m2 to the current 600g/m2, and there are only 500g/m2 corrugated board in some countries. At present, the corrugated board produced in China is generally high quantitative, which wastes a lot of resources, and has to import a considerable amount of high-strength corrugated base paper every year

with the continuous development of society and the improvement of consumption level, the printing of corrugated boxes must gradually develop in the direction of high-grade, high-quality, multi-color and strong visual effect, and take the color surface multi-color dot printing as the direction, that is, replace the transportation packaging with commodity packaging, and replace the board ox card with white board ox card, so as to achieve the effect of bright color, good gloss and beauty. In order to achieve the above effect, for example, in many structural auto parts and markets with similar requirements, higher requirements are put forward for plate making and ink. For medium and high-grade carton printing plate making, flexible plate must be used to replace rubber plate. Although the cost is high, the printing effect is very ideal. High quality water-based ink must also be used to achieve gloss, bright color, fast drying, and adapt to high speed and efficiency

in addition to plate making and ink, higher requirements are also put forward for water-based printing slotting machine, which must be high-speed, accurate chromatic registration, and the error is plus or minus 0.5mm. China's printing slotting machines have made great progress and improvement in recent years. The water-based printing slotting machines produced by Shanghai Dinglong and Guangdong Dongfang have reached a relatively advanced level and are sold well at home and abroad. Printing quality is an important aspect to improve the quality of the whole carton. If the die-cutting process is used for trimming, slotting, crimping and corner cutting, it will be neat, smooth and beautiful

with the strengthening of the awareness of environmental protection in the whole society, there will be a lot of room for the development of green paper packaging, and the corrugated box industry should expand the service objects of its products

1. The traditional service objects of corrugated box packaging are outer packaging and transportation packaging. In the future, we should actively develop new products, such as micro fine corrugated box, supermarket goods, honeycomb paperboard, etc., from both breadth and depth

2. Corrugated box packaging should also actively develop to sales packaging. With the development of the commodity market, corrugated boxes not only have packaging functions, but also advertising functions. The carton industry should continue to develop its potential functions

3. Kraft linerboard transportation packaging will gradually be replaced by white kraft paper cartons with color printing, so as to realize the integration of internal and external packaging goods at the northeast border. The carton industry should determine the response strategy as soon as possible
