Since corrugated cardboard is an important paper packaging material, the world’s corrugated cardboard production has increased every year since 1995. In 1995, the output of corrugated cardboard was 110.403 billion square meters, and in 2000, the output reached 125.285 billion square meters.
According to relevant data, the output of corrugated cardboard on all continents in 2000 was as follows: America ranked first, with 42.596 billion square meters, accounting for 34% of the world’s total output; Asia was second, with 39.037 billion square meters, accounting for 31.2% of the world; Europe ranked first The third place is 34.173 billion square meters, 27.3%; the fourth South America is 6.506 billion square meters, accounting for 5.2% of the world; Africa is 1.640 billion square meters, 1.3%; Oceania is 1.372 billion square meters, accounting for 1.1% of the world
Corrugated board industry market comparison
Most corrugators in European and American countries are wide-width, high-speed production lines, and a complete and efficient production system has been formed, which can change specifications without stopping. Therefore, these production lines have a wide range of adaptability and great production flexibility. It can complete the production of large quantities of orders, and can also complete the production of very small quantities of orders in continuous operations.
From the perspective of the output efficiency of a single production line, the efficiency indicators of several major European and American countries are: 6451 in the United States, 5670 in Germany, 4440 in France, 3670 in the United Kingdom, and 3260 in Spain. The unit is 10,000 square meters/single line/year.
European and American countries have complete sets of carton back-end processing equipment, specific functions and diverse varieties;
Take Canada, which has a small carton industry, as an example. The country produces 2.54 billion square meters of corrugated cardboard annually. It has 129 carton factories, 63 carton processing factories, and 45 corrugated cardboard production lines. There are more than 900 sets (sets) of equipment, including a total of 636 sets (sets) of various printing slotting gluing machines and nail box machines, folding nail box machines, and 157 sets of flat-bed and rotary die-cutting machines. 120 sets of finishing and finishing equipment. Its matching degree is far greater than the usual matching ratio of watt line/printer machine 1 to 3.
3. Product Evaluation
Functionalization: The functionalized packaging and finishing processing of carton boxes in European and American countries are used to display the beautifying content of the packaging, which is more common and strengthened. In addition to fine printing, the application of auxiliary materials and coating and finishing are another aspect. For example, the application of refined paraffin and emulsified paraffin has greatly enhanced the effect of fire-resistant functional packaging and product preservation; the color paper box is changed from the traditional yellow color to the plain color, which has greatly improved the effect of beautifying and promoting products; carton boxes Surface treatment technologies such as surface coating can also play a role in adjusting the atmosphere, preserving freshness, and eliminating static electricity. They can be used to package flavored foods, and are also of great benefit to certain fruits, vegetables, and microelectronics.
Carton structure: In developed countries, three-layer cartons account for the vast majority, accounting for 88.7%-89.4%, double-wall five-layer cardboard accounts for 9.1%-9.5%, and three-watt seven-layer cardboard accounts for only 0.5%-0.6%. In recent years, the application of heavy-duty packaging and full paper pallets has increased, and the proportion of the latter has increased, but the proportion is still small. This is another embodiment of the characteristics of lightweight packaging and green packaging that saves resources and energy.
Corrugated structure and polarization: in the United States, the basis weight of cartons is as small as 500-510 g/m2; the average unit weight of cartons in five European countries such as France also decreased from 550-570 g/m2 in 2002 to 510 in 2004. -520 g/m². There are various corrugated structures, including A, B, C, D, E, F, G, and N corrugated. Among them, E corrugated is called micro-corrugated below. The heights of F, C, and N corrugations are 0.75-0.81mm, 0.50-0.58mm, and 0.46mm, respectively; in recent years, O-type corrugations have appeared again, with a corrugated height of 0.3mm. In addition, the extra-large corrugated K type that has been available in the early years, with a height of 12.7-19.6mm, double-arch (two-layer core paper) molding, is used for heavy-duty packaging and packaging occasions with vibration and shock resistance. In this way, the functional packaging function of corrugated boxes is more comprehensive and strengthened. At present, micro-fluted corrugated cardboard has not really entered the corrugated paper processing field in developing countries around the world, and the application of heavy-duty corrugated cardboard is also far from social demand.
4. Cost comparison
Now, the global corrugated box industry is surging, and the competition is very fierce. It can be said that the competition of global corrugated boxes mainly lies in the competition of economic cost of enterprises.
The more representative ones are the United States and China. According to data, the cost of base paper in American carton factories now accounts for 80%, and the cost of base paper in China accounts for 75%. The production of corrugated carton enterprises has fully entered the stage of quantitative analysis, and various scientific methods have been selected to minimize the cost of carton boxes. Through the quantitative analysis of stock orders and raw materials, choose the best cost plan, cooperate with the same industry online, form a strategic alliance and develop together.
