characteristics and application of honeycomb corrugated paperboard the development technology of honeycomb paperboard in China began in the late 1980s. After years of research, development, continuous improvement and improvement, China’s honeycomb paperboard technology has made a breakthrough so far. At present, domestic honeycomb paperboard technology and equipment have been greatly improved in terms of equipment processing accuracy, honeycomb paper forming strength and range, as well as reducing energy consumption and production cost. 1、 The main characteristics of honeycomb paperboard honeycomb paperboard is a new type of environmental protection and energy-saving material with sandwich structure, which is composed of high-strength honeycomb paper core and various high-strength kraft paper. It has the advantages of low cost, less materials, sound absorption and heat insulation, high strength, good impact resistance and so on. 1. Light weight, less materials and low cost. Compared with other plate structures, honeycomb sandwich structure has the largest strength to volume ratio, so its finished product has a good performance /price ratio, which is the key to the success of honeycomb paperboard. The density of ordinary honeycomb paperboard is about 30 ~ 50kg /m, which is 1 /3 of that of common corrugated paperboard. The price of ordinary honeycomb paperboard is only 60% of wood, 50% of steel and 66% of heavy seven layer corrugated paperboard. Due to its light weight, it can bring better economic benefits to users. 2. High strength, flat surface and not easy to deform. The honeycomb sandwich structure is approximately isotropic, has good structural stability and is not easy to deform. Its outstanding compressive capacity and flexural capacity are the important characteristics of box packaging materials. The front face of ordinary honeycomb paperboard can bear 2-5kg pressure per square centimeter, which is 5-10 times the compressive capacity of ordinary corrugated paperboard. The bending strength of ordinary honeycomb paperboard is 2-5 times that of reinforced corrugated paperboard and 5-30 times that of ordinary corrugated paperboard. 3. Good impact resistance and cushioning. Honeycomb paperboard is made of flexible paper core and tissue paper. It has good toughness and resilience. The unique honeycomb sandwich structure provides excellent cushioning performance. It has higher unit volume energy absorption value in all cushioning materials. High thickness honeycomb paperboard can replace the EPS plastic foam cushion which has been widely used. According to the research, the compressive strength of honeycomb corrugated paperboard increases approximately linearly with the increase of paperboard thickness and length. The compressive strength of AB corrugated honeycomb corrugated board can reach 8.5kgf /cm square, A Leng can reach 8.5kgf /cm square, B Leng can reach 14kgf /cm square, much higher than the compressive strength of EPS foam plastics. 4. Sound absorption and heat insulation. The interior of honeycomb sandwich structure is a closed chamber filled with air, so it has good sound insulation and heat preservation performance. 5. No pollution and in line with the trend of modern environmental protection. Honeycomb paperboard is made of recycled paper materials, which can save wood instead of wood and replace EPS plastic cushion. It can be recycled after use. The waste products and leftover materials in the production process of corrugated box can also be bonded after die-cutting to make honeycomb corrugated board cushion pads of various shapes. Even if they are not used, they can be naturally degraded and absorbed. They are good green environmental protection packaging materials. 2、 The application of honeycomb paperboard in packaging. Honeycomb paperboard products save resources, protect the ecological environment, have low cost, low price, wide application and good prospect, and are in line with the application and development trend of international packaging industry materials. As a new type of packaging material, honeycomb paperboard is widely used in the packaging of electronics, electrical appliances and other items, especially for the cushioning packaging of heavy household appliances, electromechanical products, mechanical parts, ceramic products and other industrial products. It can be made into honeycomb tray, packing box and packing lining. 1. Honeycomb molded tray. Honeycomb molded tray is made of honeycomb molded plate as the top plate and bottom plate of the tray, and the middle and four corner cushion blocks are bonded by round paper tube or small multi-layer honeycomb paperboard. After drying and forming, a complete honeycomb paper-based molded tray is made. In order to meet the performance requirements required for the use of pallets, necessary chemical additives must be added. (1) adding dry strength agent, such as modified starch, cationic polyacrylamide and polyvinyl acetate emulsion. (2) Add wet strength agent, such as polyamide propylene oxide resin (PAE); (3) Sizing agents, such as water-soluble acrylate polymers. This production process adopts the mixed molding of waste pulp and pollution-free additives in a certain proportion. The production process is simple, the production process does not discharge harmful substances, and the wastewater is recycled, which has almost no load on the environment and meets the requirements of environmental protection. Compared with wooden pallets, honeycomb pallets have better cushioning; Medium performance, its flat compressive strength can reach more than 20t, and its bending strength can reach about 1t, which can play a good protective role for the product. 2. Honeycomb packing box. Honeycomb packing box is a high-strength board composed of high-strength honeycomb paperboard with frame and various hard plates or high-strength waterproof kraft cardboard. It is a new energy-saving packing box with paper instead of wood. The outer hard and inner soft composite box plate of the packing box is resistant to external puncture and has buffer protection for the inside, which realizes the unity of packaging and protection, with flat surface, no seam, tight box coordination, beautiful appearance and convenient printing. It can meet the packaging requirements of 13 products and reduce the commodity inspection obstacles of export commodities. It is a good substitute for wooden packing boxes. 3. Honeycomb packaging lining. According to the shape of the package, honeycomb paperboard can be used for a variety of processing and made into a variety of packaging linings. Compared with the traditional polystyrene foam (EPS), the honeycomb packaging lining has higher strength and better cushioning property. Processing does not need mold forming and is not limited by batch. At the same time, it can also reduce the volume of packaging containers, reduce packaging materials and reduce transportation costs; Moreover, the material can be recycled to avoid white pollution and realize the best protection and rational utilization of resources.
