Corrugated board plays an important role in the field of "green packaging"

According to the concept of sustainable development, green environmental protection packaging materials refer to packaging materials that can not pollute the environment, ensure human survival safety, make full use of resources, reduce consumption and save natural resources. Green packaging materials will not pollute the environment in the whole life cycle of its development, production, circulation and recycling.

In recent years, as a green paper packaging material, corrugated board has developed rapidly in China. Its consumption accounts for more than 60% of paper packaging materials, and began to extend to other fields.

After nearly 30 years of development, China's corrugated board industry has formed a scale. At present, it has 4000 corrugated board production lines, with an annual output of 20 billion square meters. Products with corrugated board as raw materials include cartons, cartons, trays, paper corners and extended products, such as house partitions, furniture products, supermarket shelves, display shelves, cushioning materials, etc.

Because corrugated board production does not need high and new technology and the access threshold is low, the competition in this industry is very fierce. In the face of the unprecedented financial crisis in the current international market and the relative reduction of China's export products, how to deal with the fierce market competition and make the healthy and sustainable development of the industry become the focus of the industry.

Experts pointed out that in the future, the development of China's corrugated board industry should pay attention to the following aspects

The industry realizes large-scale production. At present, China has more than 3000 tile lines with overcapacity. Although the United States has only more than 1000 production lines, its output ranks first in the world, mainly because of the high degree of modernization and scale of enterprises. In the current situation of fierce market competition in China, eliminate backward equipment with low manual or automation degree, high energy consumption and low efficiency, such as production lines with a line speed of less than 80m per minute and a width of less than 1.6m, introduce automatic control equipment with a width of more than 2m and a line speed of more than 150m / min, and carry out scientific management of the production of the enterprise, To enhance the overall competitiveness of enterprises is the development focus of corrugated board industry in the future.

Product functions are developing in a diversified direction. At present, corrugated board should develop from a single transportation and packaging function to a multi variety, multi-function and multi-purpose direction. In the field of packaging, high strength, low gram weight and light weight will replace the traditional five or seven layer board, reflecting the environmental protection concept of high quality and low consumption. At the same time, products should also develop from a single packaging function to beautifying product functions. At present, corrugated board has developed from traditional a, C, B and D types to e, F and G types. The new corrugated board can not only meet the requirements of high strength, but also reflect the characteristics of saving materials, direct printing and exquisite surface patterns. At present, the three-layer tile plate in developed countries in the world has reached more than 80%, while China accounts for only 30%. In addition, the industry should break the situation that a single variety of corrugated board products dominate the market, and develop micro corrugated board, heavy corrugated board, moisture-proof and water-resistant corrugated board, fresh-keeping corrugated board, anti embroidery corrugated board, etc.

High strength corrugated paperboard can replace wooden tray, reduce wood consumption, tile plate gasket instead of foam plastics, reduce white pollution, replace plastic, wood and metal packaging materials, and have broad market prospects in the packaging of color TV, refrigerator and mobile phone products.

The industry should promote the preprint process. The printing of corrugated boxes in China mostly adopts the printing after plate making. In the process of high-speed printing, due to the influence of many factors, the multi-color printing accuracy of paperboard is not high and can not meet the requirements of high quality. The flexographic pre printing with water-based ink is to print on the web before the tile plate is formed. After printing, the web is still the web, and then the printed web is used as the tile line on the carton surface paper to make the tile plate. Flexographic printing has the advantages of non-toxic, pollution-free, multi-color, large format, low cost, high efficiency, high precision and good quality. It is suitable for the production of large quantities of corrugated boxes such as food and medicine.
