In today's world, environmental protection is one of the key issues for human survival in development. The problem of environmental pollution and waste of resources caused by packaging has attracted the attention of all countries in the world. Therefore, green packaging has undoubtedly become the mainstream development direction of international packaging. At present, EU countries have strict restrictions and regulations on packaging materials, accessories and packaging wastes such as wooden pallets, wooden packaging boxes, EPS foaming plastics, adhesives, printing inks, and paints. This constitutes the export of goods to China. Direct obstacles. Therefore, as a new type of green paper packaging honeycomb paperboard and pulp molding, not only can meet the requirements of saving resources, protecting the ecological environment, but also in line with the international packaging trends.
Honeycomb cardboard
Honeycomb cardboard overview
Honeycomb cardboard is made according to the structural principle of nature's honeycomb. It adopts recycled paper to form a series of uniformly distributed hexagonal-shaped daily-dyed honeycombs, and then it is continuously bonded to different renewable materials that can be used as a new environmental protection material after drying and curing. Its production process, as shown in Figure 1.
The structure of the honeycomb paperboard consists of upper and lower 2-layer paper, and the middle is a honeycomb core paper, which is adhesively bonded into a 3-layer structure. The thickness change of the honeycomb paperboard mainly depends on the change of the thickness of the honeycomb paper core, and its thickness generally varies from 5mm to 90mm. The column hole size of the honeycomb paper core can also be changed according to the required strength.
Because of its versatility, high strength, great bearing capacity, good elasticity, low raw material, low cost, low quality, and recyclability, Honeycomb Paperboard can meet the packaging needs of electronic and electrical appliances, especially for heavier home appliances and electromechanical devices. Buffered packaging of industrial products such as products and ceramic products. Honeycomb paperboard can be made into honeycomb trays, packing boxes and packaging liners. At the same time, the honeycomb paperboard forms a new honeycomb composite by compounding with other materials. Honeycomb composite material is a new type of material with characteristics of light weight, high strength and high rigidity. It is also used in construction, furniture manufacturing, packaging and transportation. It has functions of buffer, vibration isolation, heat preservation, heat insulation and sound insulation. Industry, replacing wood, clay bricks and high-expanded polystyrene, has a high economic value; at the same time can be recycled, save a lot of forest resources, protect and improve the ecological environment, is a new green packaging material that meets the requirements of environmental protection.
Application of Honeycomb Paperboard in Packaging
Honeycomb cardboard box
Honeycomb paperboard boxes are affixed with different grammage papers on the honeycomb paper core underneath, and made into various forms and sizes of packaging boxes. This kind of packing box is an ideal container for fragile, fragile and high-grade goods packaging, and can be used instead of corrugated boxes.
Honeycomb cardboard lined boxes
The packaging box adopts a honeycomb paperboard with better cushioning properties on the inner surface of the original corrugated cardboard box, which can enhance the shockproof, compressive, and anti-jamming capabilities of the corrugated box, and is more suitable for electronic products, glassware, instruments, and medical equipment. Packaging of valuables such as equipment.
Honeycomb cardboard tray
The pallets and beams are made of cured honeycomb paperboard, which is inexpensive and easy to recycle. It is suitable for storage and one-time use.
Honeycomb cardboard composite tray
Honeycomb paperboard composite trays are made of honeycomb paper core and fiberboard. Beams are made of wood beams or composite cores. The frame is made of wood. Such pallets can bear heavy weight and can be reused. In a certain range, they can replace wooden pallets, steel flat pallets, etc. The cost is only 1/3 of the steel pallets. After adoption, it can save money and achieve better economic benefits.
Honeycomb composite panels for furniture applications
In the manufacture of furniture, honeycomb composite materials are mostly used in the form of honeycomb composite panels. Honeycomb composite panel is a composite panel made by thin stencil and honeycomb paper core that has been sizing and pressure bonded. As a sandwich material, the honeycomb paper core material only accounts for about 1% to 5% of the solid material. Using 1 ton of honeycomb paper composite material can replace 30 to 50 cubic meters of wood. as shown in picture 2.
