The new structure of honeycomb paperboard applies modern bionics principle, using kraft paper as raw material and made by special process and equipment. The new structure honeycomb paperboard material has been widely promoted due to the following features:
Significant. The scientifically processed honeycomb paper core has important characteristics. After testing, the load bearing capacity of the lOmm-thick honeycomb paperboard is 0.5 tons/square meter, which is 2 to 10 times that of the five-layer corrugated paperboard.
Good elasticity. Due to the different sparse density of the honeycomb structure of the honeycomb paperboard inner core, the elasticity range thereof is large, thereby resulting in strong seismic resistance. Due to its unique natural honeycomb structure, the high-strength B honeycomb core paper has strong compressive and bending resistance. The compressive strength of the lOmm-thick honeycomb paperboard is 2-75.6 times that of the five-layer corrugated cardboard, and its bending strength is Five times the transverse strength of the five-layer corrugated cardboard, 29.2 times the longitudinal strength.
Light weight. 1 square meter of 25.1mm thick five-layer corrugated paper can make 1.44m2 of 10mm thick honeycomb paperboard. Its weight is only 2/3 of the same size corrugated board and 1/3 of the wooden board.
low cost. Because honeycomb paperboard has less raw materials than corrugated paperboard and has a wide range of raw materials, honeycomb paper cores are manufactured using low-cost kraft paper, so that the material cost of honeycomb paperboard is only 2/3 of the size corrugated board and 1/3 of the wood board.
According to the statistics of China Packaging Yearbook 2001, the output value of China's paper product packaging production has increased year by year, and the paper industry and packaging industry will face the severe situation of shortage of raw materials due to the country's restrictions on timber felling. Therefore, the ideal “paper and wood†is sought. Packing instead of materials, adopting the new structure of wood-saving honeycomb paperboard materials to gradually replace the traditional corrugated paper will become an important trend in the development of China's packaging industry; the current foreign substitution rate has reached more than 70%.
Through the government's policy orientation, the traditional and high-energy corrugated paperboard production lines are gradually restricted and eliminated, and the adoption of advanced new structural honeycomb paperboard production lines is encouraged and supported. It will also become an important trend in the renewed development of China's packaging industry equipment.
The government has begun to guide the policy direction of China's packaging industry. Honeycomb paperboard is favored by packaging and other related industries due to its unmatched superiority and good development prospects. Recently, the State Economic and Trade Commission forwarded the “Opinions on Strengthening National Packaging Improvement Work†of the National Packaging Improvement Office to make it clear: “The quality of the box packaging is poor. It is necessary to speed up the development and application of honeycomb paperboard and gradually replace some of the wood packagingâ€. The “Research on Development Strategies and Planning of China's Green Packaging Industry†developed by the Comprehensive Utilization and Environmental Protection Division of the State Economic and Trade Commission’s Department of Resources and Resources has clearly included the honeycomb cardboard packaging box in the promotion development plan, and pointed out: “This new type of honeycomb paperboard The box will become the ideal packaging for China's export commodities, and its popularization and application will play a positive role in reducing the breakage rate of commodities in the circulation process and improving the quality of packaging products."
The new structural honeycomb paperboard material project can stimulate the development of various industries and solve the re-employment problem. This project can be widely used in the tobacco industry, ceramics industry, glass storage industry, pallets in port and dock transportation industry, military weapons ammunition depots, hygienic facilities for funeral industry, furniture industry, building and building materials industry, agriculture potted plants, flower industry and most of the Corrugated carton packaging industry equipment replacement or replacement of foam plastic packaging industry with honeycomb paper core cushions. Can pull the corresponding development of various industries in the national economy. After the project has driven the development of dozens of related industries across the country, it is expected to resolve the reemployment of millions of laid-off workers and contribute to social stability and economic development. Take Kunming R&D Center as an example: After implementing the national high-tech industrialization project “New Structure Honeycomb Paperboard Materials†demonstration project of Kunming R&D Center, it has solved the problem of laid-off and re-employment for hundreds of people inside the company, and also merged more than 900 times. The bankruptcy enterprise of the people—Yunnan No. 1 Light Industry Machinery Factory has contributed to the social stability and economic development of Kunming City.
In the process of industrialization, the state needs support
The government should gradually restrict the investment in the construction of traditional corrugated cardboard production lines from the policy orientation, and through enterprise restructuring, shut down, stop, and transfer those small and medium-sized corrugated cardboard box packaging plants with poor economic returns and backward equipment.
The state should take strict measures to prohibit the production, sale, and use of EPS foamed plastics as cushions in packaging boxes (the international deadline is 2000, forcing manufacturers to adopt environmentally friendly honeycomb paper core cushions as soon as possible.
The government should actively encourage investment in those projects that adopt the new structure of honeycomb paperboard materials from the policy orientation; and provide support for tax reduction and exemption for project construction units.
It is suggested that the government should actively encourage export enterprises in China to use honeycomb carton boxes and honeycomb trays for export packaging to solve the “Cattle†problem, reduce fumigation costs, promote foreign trade, reward rewards to active units and meritors, and actively use environmental protection. Products - Honeycomb cartons, honeycomb trays of the company to give up the "export packaging permit" and reduce the relevant fee. It is suggested that the government give preferential policies for partial reduction of business tax to enterprises that use cellular paper core cushions instead of foaming to promote the elimination of “white pollution†in China.
