In recent years, with the increasing voice of environmental protection, consumers have higher and higher requirements for cushioning packaging materials. Due to the serious environmental pollution problem, the environmental protection packaging materials widely used in the market are corrugated board and honeycomb board.
However, because honeycomb paperboard has the advantages of reasonable structure, light weight and high strength, corrugated paperboard is regarded as a competitor.Corrugated Board And Honeycomb Board
In fact, corrugated board and honeycomb board have their own advantages and disadvantages. Therefore, how they will develop in the future is a problem worthy of consideration
Characteristics of corrugated board
Corrugated board is a kind of widely used board with paper instead of wood, especially for commodity packaging. According to the shape of corrugated, it can be divided into u, V and UV corrugated.
According to the cross-section structure of the corrugated layer, it can be divided into five kinds of corrugated boards: A, B, C, D and E. According to the number of corrugated layers,Corrugated Board And Honeycomb Board
it can also be divided into one layer, two layers, three layers, five layers and seven layers of paperboard (i.e. triple corrugated paperboard). The main features of corrugated board are:Corrugated Board And Honeycomb Board
(1) The corrugated box made of corrugated board is usually transported in the form of folding or tiling, which is convenient to carry, improves the transportation efficiency and saves the storage space.Corrugated Board And Honeycomb Board
(2) The production cost of corrugated cardboard packing box is low and saves materials.Corrugated Board And Honeycomb Board
(3) It has high strength and good cushioning performance, which can avoid the collision and impact of the packaged goods. It is especially suitable for the transportation and packaging of machinery, electromechanical and other heavy products.Corrugated Board And Honeycomb Board
(4) The production of corrugated boxes can be carried out on highly mechanized, automatic and efficient equipment with high work efficiency.
Characteristics of honeycomb paperboard
Honeycomb paperboard is made according to the principle of honeycomb structure in nature. It is a new type of environmental protection and energy-saving material with sandwich structure, which connects the corrugated base paper into countless hollow three-dimensional regular hexagons by glue bonding method to form an integral stress-bearing part – paper core, and adheres face paper on both sides. The main features of honeycomb paperboard are:
(1) Light weight, less materials and low cost. Compared with other plate structures, honeycomb sandwich structure has the largest strength / mass ratio, so the performance / price ratio of its finished products is good, which is the key to the success of honeycomb paperboard.Corrugated Board And Honeycomb Board
(2) High strength, flat surface, not easy to deform. 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 most important characteristics required by box packaging materials.Corrugated Board And Honeycomb Board
(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. The honeycomb paperboard with high thickness can replace the EPS plastic foam cushion which is now widely used.
(4) Sound absorption and heat insulation. The interior of the honeycomb sandwich structure is a closed chamber filled with air, so it has good sound insulation and thermal insulation performance.Corrugated Board And Honeycomb Board
(5) No pollution, in line with the trend of modern environmental protection. Honeycomb paperboard is made of recycled paper, which can be recycled 100% after use.Corrugated Board And Honeycomb Board
The waste products and leftover materials in the production process of corrugated boxes can also be bonded after die-cutting to make honeycomb corrugated board cushion pads of various shapes. Corrugated Board And Honeycomb Board
Even if they are not used, they can be degraded and absorbed by nature. They are good green environmental protection packaging materials.Corrugated Board And Honeycomb Board
In European and American countries, the wood packaging required for goods imported from China must be fumigated, and honeycomb paperboard, as a new environmental protection material, can fully meet the packaging requirements of European and American countries for goods imported from China.
