Development of the hottest wood packaging 1

Development of substitute wood packaging

substitute wood heavy packaging in developed countries, including the use of high-strength multi-layer (double arch) corrugated boxes (box Department); Non wood products tray (seat part); The technology and equipment of edge, corner, bottom and top reinforcement structural materials and the application of non lignified materials used as buffer, positioning, protection and auxiliary materials (combined filling part) for septum, liner and filling have a high current level

high strength multi-layer corrugated cardboard box

for small and medium-sized wood substitute cartons, three layers of corrugated cardboard (generally seven layers) are generally used; It can be made into heavy-duty packing boxes through automatic production lines, which are fixedly connected with wooden pallets at the bottom of the box (in recent years, paper pallets and non wood composite pallets have been gradually used). Rexam company of the United States uses two three-layer and seven layer corrugated cardboard to stick together to make and form a 14 layer overweight corrugated cardboard box, which can bear large Ford Trucks with a load of more than 7.5 tons

among the heavy-duty packaging cartons, there are also large cartons in the shape of octagonal prism. In addition, octagonal shallow plate-shaped bottom and cover are made to form a heavy-duty packaging container by bonding with glue after the packaging operation is completed. This avoids the fracture of multi-layer ultra thick paperboard when it is folded into boxes to form a right angle from 2005 to 2010. In Japan, this large container box weighs 3.45 tons of plastic granular materials (the size of the box is 2.5 meters in diameter and 2.3 meters in height)

there is also the super rigid high-strength multilayer corrugated board with staggered bonding in the vertical direction of corrugated, which overcomes the difference in the direction of the comprehensive strength index before completing the dream of multi-dimensional material map, and has the advantages of mutual strength complementarity. It is used as the base plate of heavy-duty packaging boxes and pallets, which can be seen on the pallets and pallets of imported goods, exhibition machine tools and product containers

application of honeycomb paperboard

it is of great use as a cushion and partition in heavy-duty packaging boxes, as a wall panel material for load-bearing reinforcement in cooperation with the inner wall of boxes, and in the production of all paper pallets. The United States has the production and service business of waterproof honeycomb paperboard all paper pallets and cushioning protective packaging materials used as corners and bottoms

in foreign countries, packaging cartons made of honeycomb paperboard are rare. Israel uses 8-10 mm thick honeycomb paperboard to make packaging boxes for cigarettes, jade and porcelain. Its packaging equipment and process are similar to the processing equipment and process of corrugated boxes. The processing of thick honeycomb paperboard into boxes is not so convenient. Like the production of honeycomb paperboard, some links are not easy to be connected into automatic lines, and high-speed production cannot be carried out. This is inconvenient for the "low profit" carton industry to rely on mass production to obtain high efficiency of large-scale production

nevertheless, the speed, performance and product quality of foreign honeycomb paperboard production lines are still higher than those of domestic equipment, so the price is very high. The price of the honeycomb paperboard production line of IMA engineering company in Israel is US $1.1 million (9.24 million yuan); The asking price of American OMS company is 1.2 million dollars (10.4 million yuan); Dutch hollyson company offers 20million yuan. Other foreign companies also have such production lines available, such as honeycomb paper technology companies in Japan, Britain, Finland and the United States

application of substitute wood pallets

substitute wood pallets include honeycomb cardboard pallets, pulp molded pallets, and paper filled ribs, which are senior researcher Xi Guodong of Autodesk software (China) Co., Ltd. Plastic tray, metal tray, etc. They, together with the packing cases, as a whole of transportation packaging, participate in the high-quality circulation process, which has a history of more than 20 years abroad
