Honeycomb paperboard is a new type of packaging material with high strength, high elasticity, great bearing capacity, low cost and recyclability. It is greatly superior to traditional paper packaging boxes and wooden packaging boxes in terms of protecting packaging items and reducing packaging costs. Widely used in tobacco, glass ceramics, air transport, warehousing, construction, furniture, health care and other industries, is an ideal product to replace the traditional packaging materials. In recent years, developed countries such as Europe, the United States, and Japan have invested a lot of manpower and material resources in the development of honeycomb paperboard production equipment and technology.
In recent years, China's policy of supporting honeycomb paperboard packaging materials has been introduced frequently. In 1999, the "Research on Development Strategies and Planning of China's Green Packaging Industry" compiled by the Department of Comprehensive Utilization and Environmental Protection of the State Economic and Trade Commission, listed the honeycomb paperboard packaging as an extension development plan, and pointed out: "This new kind of honeycomb paperboard will become our country. The ideal packaging for export goods, and its promotion and application will play a positive role in reducing the breakage rate of goods in the circulation process and improving the quality of packaging products.†In April 2000, the honeycomb paperboard was also identified as a new material by the State Planning Commission. Industrialization work focus. In August 2001, Honeycomb Paperboard, one of the “New Generation Wood Packaging Materials†specialties organized by China National Packaging Corporation, was included in the National Key Technology Innovation Plan. In terms of packaging and transportation, the promotion and application of honeycomb paperboard has been included in the national packaging improvement "Ninth Five-Year Plan".
As a country with a relative lack of resources, rapidly expanding export commodities, and an increasingly urgent need for sustainable development, the development of paper honeycomb products in China is an inevitable trend.
Honeycomb Paperboard Features and Benefits
Honeycomb paperboard is a new type of paper which is made of paper honeycomb with a honeycomb structure as the base, and is bonded on both sides with linerboard and single corrugated cardboard. The scientific principle is: Scientists have discovered that the hexagonal hexalobular nest made by bees is a masterpiece. It builds the most solid honeycomb with minimal material consumption, and its structure is more reasonable than any other shape structure. Because of this multi-wall arrangement and a series of continuous honeycomb-shaped mesh structures, external forces from various parties can be distributed and the pressure resistance can be greatly enhanced. The inspiration of the honeycomb structure is that even a very thin material, as long as it is made into a honeycomb shape, can withstand a lot of pressure. According to this principle, the structure of the honeycomb paperboard is the upper and lower two-layer paper (or paperboard), and the middle is a core paper in a natural honeycomb state, and the core paper is adhered between two layers of paper with a certain adhesive. A three-layered structure is formed, which is similar to a single corrugated cardboard structure. The difference between honeycomb paperboard and corrugated paperboard is that the thickness change of honeycomb paperboard is mainly achieved by increasing or decreasing the thickness of honeycomb paperboard. The structure always maintains three layers, and its thickness can vary from 5 to 90mm, unlike corrugated paperboard. Increase the thickness by increasing the number of layers of corrugated board; the size of the hole in the sandwich hole of the honeycomb board can be changed, and its change can change the strength of the honeycomb board, which is also different from the corrugated board.
The structure of honeycomb paperboard determines its characteristics, namely, light weight, uniform compression, high pressure resistance, bending resistance, high shear strength, good buffer vibration isolation performance, low cost, easy recovery, and regeneration. Green, energy saving, environmental protection, high-tech new packaging materials.
Honeycomb paperboard covers all walks of life, from small motors to large aircraft engines. Honeycomb paperboard packaging can be used, especially in the field of packaging and construction. Paper-to-paper and paper-based wood are the general trend. The benefits are widely viewed, and the development of paper honeycomb products in China is an inevitable trend. Because its weight is only one-third of the same size wooden box and wooden pallet, but its load-bearing can be more than wood-based packaging, it is 2 to 10 times the five-layer corrugated cardboard; plus multi-walled honeycomb structure, falling And the impact is evenly shared, for this purpose. The vibration resistance is particularly excellent, and high-expanded polystyrene is generally not included in the packaged goods. In addition, it can be recycled or incinerated, and will not pollute the environment. Therefore, it is internationally recognized as a 3R green packaging.
Application of Honeycomb Paperboard in China
The application of honeycomb paperboard mainly has four aspects. One is used as a cushion liner. The honeycomb sandwich structure of honeycomb paperboard makes its buffering performance better than that of corrugated cardboard. It can use full buffer or partial buffer to protect the contents; the second is used as tray, honeycomb paperboard tray and wooden tray. Compared with light weight and high strength, it can be used as ordinary flat tray and single-sided tray. It can also be used to set up column tray structure. Third, it is used as packing box. Like corrugated cardboard box, honeycomb paperboard can be processed into cardboard box. , but generally only use thinner honeycomb paperboard to make cartons; fourth is to use as gussets, guard edges and other accessories. Similar to cushion liners, honeycomb paperboard can be used as gussets and protection edges for transport packages. Suitable for assembly packaging, protection, reduce collision and friction, reduce damage.
From a practical point of view, honeycomb paperboard is popular in home appliance packaging in China. At present, there are many situations in which electronic equipment and household appliances exported from China are replaced with honeycomb paperboard, water quality trays, packing boxes, and EPS foamed plastic cushions.
Gree Electric Appliance Co., Ltd. took the lead in the use of honeycomb paperboard packaging air conditioners in previous years. An air-conditioning production line requires about 3,000 sets of honeycomb paperboard liner materials every year, and consumes about 20 million square meters of honeycomb paperboard every year; Kelon Air-Conditioning Co., Ltd. established projects in 2000 to improve the original Air-conditioned packaging, replacing the original packaging with honeycomb paperboard and EPE. This program began in 2002 and was put into use in batches. It was fully applied in 2003 and used about 40 million yuan in honeycomb paperboard materials. At the same time, Kelon brand refrigerators will also use honeycomb paperboard to replace the original EPS plastic packaging materials. Oaks Company exported 300,000 sets of air conditioners with honeycomb paperboard packaging in 2003. The number of export air conditioners will account for 50% of the company's total air-conditioning output in the next 3-5 years, and the amount of honeycomb paperboard will also be considerable. Haier's air-conditioning cabinets began to formally use honeycomb paperboard packaging materials in early 2004. The current daily usage has exceeded 20,000 square meters, and will also be promoted and applied to refrigerators and other electrical products. According to Haier's development plan, the Group's various products will gradually adopt honeycomb cardboard packaging, and the annual demand will be around 50 million square meters.
Following the use of honeycomb paper for air conditioning, other home appliance companies have also started to deal with honeycomb paperboard. Aucma, Changhong and other well-known corporate brands at home and abroad, air conditioners, refrigerators, followed by honeycomb cardboard instead of EPS foam plastic and wooden pallets. Sichuan Changhong Electric Appliance Co., Ltd. has conducted technical research and research in the past few years. In 2002, it purchased honeycomb paperboard and paper corner protection production lines. Honeycomb paperboard was used as the main material, and corrugated cardboard, paper corner protection, pulp molding and other environmental protection were adopted. Materials, combination applications, and gradually formed the Changhong brand air conditioning, color TV, rear projection, audio-visual and other home appliances products green packaging solutions, and has gradually replaced the EPS foam plastic and wooden pallets, and achieved gratifying results. Other enterprises such as air conditioners and refrigerator compressor manufacturers—Shunde Meiyi, Guangzhou Mitsubishi Electric, Shunde Wanjiale for home appliances, Galanz for microwave ovens, Shenzhen Zhongkang Glass Shell Factory for producing glass tubes, and Foshan Color CRT Become a potential user of honeycomb cardboard. According to user feedback, the use of pulp molding and honeycomb paperboard materials not only reduces the overall packaging costs, but also helps to enhance the company's brand and image, reducing the "white pollution" and opening up a "green channel" for the export of foreign trade products. ". At present, most of the home appliance packaging uses other materials. The space for the development of honeycomb paperboard is very large.
China's honeycomb paper industry needs to be upgraded
Honeycomb paperboard began to heat up in October 1998. The reason was that in the United States in 1998, the United States discovered an insect pest such as Anoplophora glabripennis in the wood packaging of China's exported goods. On September 17th, it announced that it prohibited China’s solid wood processing without strict high temperature, fumigation or preservative treatment. Packaging material entry. Canada, the United Kingdom, etc. followed closely and successively issued similar bans to impose restrictions on China's solid wood packaging materials. In June 1999, 15 EU countries implemented emergency measures to prevent the spread of insect pests in wood packaging of Chinese products in the EU.
Since October 1998, China’s foreign trade exports have fallen, and the solution to the problem of wood packaging is imminent. The state leaders are very concerned about this and issued emergency notices on many occasions, requesting relevant departments to study countermeasures and propose solutions to the problems. About half of China's exports to the United States use wood packaging. If fumigation is used, the cost of fumigation is very high. Therefore, we must consider the development of new packaging materials suitable for China's national conditions and export needs as quickly as possible, and accelerate the introduction of substitute wood packaging materials. Honeycomb paperboard is an ideal material and has become a hot spot for popularization and application. This is the direct reason for the rapid temperature rise of honeycomb paperboard.
At present, the production and application of China's paper honeycomb products are still at the initial stage of development. The research and development of production line equipment, the structural design of products and the processing capability of products and the serialization and standardization of products are progressing slowly. The integrity, stability, processing precision, and processing quality of our country's honeycomb paperboard production line are still far from those of foreign advanced equipment. The degree of automation of production equipment is low, and some processes are still operated manually, resulting in low production efficiency. Forming processing equipment is relatively simple, in the product forming process, many processes can not guarantee high product quality, such as edge sealing, indentation, printing, moisture, flatness, smoothness, etc. There are still such problems, many factory production The surface of the honeycomb paperboard products is rough, the color is not good, it is difficult to achieve standardization, serialization, so it is difficult to meet the needs of users. Some companies' products, especially in the waterproof, moisture-proof aspects of the problems that need to be solved. In terms of cellular trays, almost all cellular manufacturers are hand-made, so there are low efficiency, low output, low quality, and high cost, and of course the cost is high. The poor quality of handmade products is not welcome. The tray line abroad has a high technological content and is expensive and of high quality. However, for some small domestic enterprises, it is elusive, foreign equipment is difficult to operate, accessories are difficult to purchase, and maintenance is difficult.
Due to lack of funds, research, development, design, production, promotion, promotion, sales and other aspects of the work have certain difficulties, the company's small-scale production, far from adapting to rapidly expanding market demand. Initially, China's paper honeycomb was developed in both directions of building materials and packaging. Its basic model is to learn from foreign experience. The first is to develop and promote equipment. In the process, related processes, materials, products, and technologies are developed. At present, this model is still the mainstream in the paper honeycomb industry. However, due to excessive profit-taking behavior and weak technological development capabilities, the entire industry has been slow to develop, resulting in a large number of low-quality, low-efficiency investments. The current state of the industry. There are mainly the following reasons: First, the technical foundation is weak, ignoring the importance of technological innovation to the development of new projects and new industries. The second is the low level of equipment investment, which on the one hand reduces the investment efficiency, and on the other hand it weakens the product development capacity from both cost and quality. According to rough statistics, nearly 20% of the equipment that has been put into use is already in abandonment. In the equipment that can be used, if it is measured by the technology and technical standards of foreign equipment, about 90% of the equipment should be phased out, and the equipment is Two extreme distributions: pursuing low cost and simplicity while pursuing unrealistically high automation and high productivity. There are very few equipments that meet the requirements of product processing and adapt to China's national conditions. (Text/Jiang Qijiang)
