Extension of corrugated and composite paperboard products (1)

The total value of China's packaging industry has risen from RMB 7.2 billion in 1980 to RMB 300 billion. The packaging market has grown at an annual rate of about 15%. This growth rate has ranked first in the world, and its total output ranks first in Asia. Second only to the United States, it ranks second in the world and has achieved sustained high-speed development. However, due to the blind production of corrugated cartons, the rapid development has led to serious loss of control, which has added to the already overcapacity situation. According to statistics, the average operating rate of tile lines in China is only 40%. According to information, the number of corrugated cardboard production lines in the United States has not reached the level in China, but its production of corrugated board is more than three times that of ours. The current situation of the corrugated paper box industry in China puts forward the requirements for the development of corrugated board products from singleness to diversification.

The trend of the development of corrugated board products from singularity to multiple orientations

The long-term simplification of the corrugated paperboard manufacturing box in China, and the foreign developed countries began to develop from a single box to a diversified product. 60% of Japan's corrugated cardboard is used to produce cartons, while the remaining 40% of corrugated cardboard is used to develop other products such as corrugated furniture, corrugated toys, light building materials, paper trays, corrugated cardboard and other diversified products. From this point of view, the development of corrugated board made-up products from singleness to diversification can greatly ease the serious surplus crisis in China's corrugated board, and it can also provide a new outlet for China's corrugated industry.

At present, there are Guilin Paper Products Packaging Factory, Guilin Chenguang Paper Products Co., Ltd., Qingdao Conghe Hengye Paperboard Products Co., Ltd., China Shengbai Packaging Industry Group, and Yongfeng Yu Paper Co., Ltd. Packaging Group, Tri-wall Changzhou Production Base, Maanshan Tianfu Carton Paper Products Co., Ltd.

Corrugated and composite board is a kind of green environmental protection material with light weight, low cost, high strength, low intensity, good performance, sound insulation, and easy recycling. In recent years, as the packaging industry has strongly advocated "relying paper for plastic and paper for wood", this green and environmentally-friendly material, as a new type of green packaging material, is gradually paying attention to and vigorously developing its application in the packaging field. This will promote the development of packaging materials to be lighter in order to reduce shipping costs. By using specially designed components and systems to shorten production time, we strive to provide a variety of packaging operations with a minimum amount of materials. The packaging industry is looking at how to reduce packaging waste and labor costs in operations and how to reduce inventory and handling costs from distribution systems. Wood packaging, wooden packaging, wood waste, plastic foam liner packaging and other white pollution, these packaging materials are more serious environmental problems, although corrugated cardboard is green paper products, but basically have not entered the replacement period.

In response to green packaging and environmental issues, the experts proposed 3R1D packaging principles for Reduce, Reuse, Recyc, and Degradab. Since the 1990s, the United States, Canada, Japan, and the European Union and other countries and regions have successively formulated strict packaging waste restriction laws. China has also promulgated corresponding policies and regulations in recent years. In this situation, paper products have achieved unprecedented development. Paper and paperboard already account for 40% to 50% of all packaging materials. At present, the country continues to restrict the cutting of timber and there will be a severe shortage of wood. Therefore, replacing paper and wood—a 100% use of waste paper and recycled paper—corrugated and composite paperboard will become an ideal material for the development of the packaging industry in China. It is imperative to accelerate the development and promotion of corrugated honeycomb composite boards and gradually replace wooden box packaging. Even in the case of fierce competition in packaging materials, especially in the case of plastic products: medium-strike, paper and paperboard still attract people's attention and continue to emerge a variety of new products, development and application of corrugated paperboard and its products have also become In recent years, China's packaging industry has been an important topic.

Corrugated and composite board use performance and advantages and disadvantages

Corrugated and composite board is a kind of light and new material with less consumables and good strength (stiffness), especially composite sandwich structure, which has outstanding compressive and bending resistance and superior performance:

â–  Low material consumption, good flat pressure resistance, high strength, strong rigidity, light weight, and easy adjustment;
â–  Light weight, heat preservation, heat insulation, sound insulation, vibration isolation, moderate shock performance, superior to wooden products;
â–  According to needs, it can also be moisture-proof, waterproof, mold-proof, antibacterial and fresh-keeping;
â–  It is an environment-friendly material and product that does not pollute the environment, has no pests and diseases, is recyclable, can be recycled, can be degraded, and has no secondary pollution, and is exported free of inspection;
â–  The price is cheaper than wood products and plastic products, which can reduce costs;
â–  Easy to carry out special processing, easy to handle and operate, improve transport efficiency.

Of course, as a packaging material, corrugated cardboard also has many deficiencies:

â–  The corrugated cardboard structure such as seven-layer paperboard, composite paperboard, various types of packaging, processing, forming more complex than a single layer of corrugated board manufacturing process;
â– Paper resistance is not strong puncture resistance, poor breaking performance, poor folding resistance;
â–  As a pad filling material and slow; Chinese materials, can not be arbitrarily shaped, there are certain limitations, slow; in the performance effect is not ideal.

Therefore, in use, we should avoid weaknesses and make full use of its advantages to make full use of its advantages.
