Development trend of substitute wood packaging in developed countries

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 application of edge, corner, bottom and top reinforcement structural materials and non lignified materials used as buffer, positioning, protection and auxiliary materials (combined filling part) for partitions, gaskets and filling has entered the stage of commercial application as early as the mid-1980s. But up to now, a certain amount of fumigated and antiseptic wooden boxes and packing boxes made of processed wood products such as plywood are still used. Its technology and equipment are of high level

high strength multi-layer corrugated cardboard boxes for heavy packaging

for small and medium-sized wood substitute cartons, three corrugated cardboard (generally seven layers) can be used to make heavy-duty packaging boxes through automatic production lines, Fixed connection with wooden pallets at the bottom of the box (in recent years, paper pallets and non full wood combined pallets have been gradually used. The United States invented the structure of combined heavy-duty cartons as early as the 1950s, and patented the use of octagonal clip pads and large square head self tightening screws to fix the bottom of the box and the seat (pallet) (. Etc.). In the early and mid-1980s, patents were introduced into Japan to form a special Naiguan packaging box, which can pack heavy items, castings Mechanical and electrical products, etc. For overweight large substitute wood packaging, the composite or combined structure of super strong multi-layer corrugated board is used. For example, American Rexam (Rexam can also be transplanted to processing and experimental equipment requiring pressure, displacement and speed) company 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

in 1998, the total output of corrugated board in the United States reached 40.33 billion square meters (11.2 billion square meters in China), with a total sales value of 19.53 billion US dollars, of which 0.5% - 0.6% were corrugated boards with more than three tiles and seven layers, and the output reached 222million square meters. This number itself shows that a considerable number of American carton factories, rather than a few, can always smell a confused smell when making heavy paper packaging boxes. The production speed of their seven layer line is as high as 155 meters/minute (in China, it is meters/minute), and it operates automatically

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 will avoid causing the multi-layer ultra thick paperboard to break when the pressing line is folded into a box to form a right angle. 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 ultra-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 and has the advantage of complementary phase strength. It is used as the base plate of heavy-duty packaging boxes and pallets, which can be seen in the pallets and pallets of imported goods and Exhibition machine tools and product containers with the deepening of China's "one belt and one road" initiative and the acceleration of the "going out" process of the new material industry

honeycomb paperboard

it is of great use as a liner and separator in heavy-duty packaging boxes, as a wall panel material for load-bearing reinforcement in cooperation with the inner wall of boxes, as well as an electro-hydraulic servo universal experimental machine for building materials as an all paper pallet. Tenneco and ixca LIBOR pallet group all have production and service businesses of honeycomb paperboard all paper pallets with waterproof treatment and protective packaging materials with cushioning performance used as corners and bottoms of boxes

in foreign countries, packaging cartons made of honeycomb paperboard are rare. Israel uses mm thick honeycomb cardboard to make packaging boxes for cigarettes, jade and porcelain, and 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

substitute wood pallets

substitute wood pallets include honeycomb cardboard pallets, pulp molded pallets, paper filled ribs, plastic pallets, metal pallets, 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. Saving resources and protecting the environment is a common thing. Therefore, there are various pallet production lines (also known as seats or pallets) for the market to choose, so the pallet quality and price are appropriate. We must develop the production technology and equipment of various pallets as one of the main contents of the innovative technology and product development of "substitute wood packaging"

paper profiles and other combined supporting devices

paper profiles, as a new protective packaging material for edge protection, corner protection, top protection and bottom protection, have opened up a new way of the so-called "container free packaging" with extremely reduced packaging. They are one of the models of green packaging and are happy for the world. All kinds of bulk goods, which only need to protect their edges and corners, do not need to be inclusive as a whole, are greatly benefited. Industrial developed countries such as the United States, Germany, France, Japan and other countries have developed and used this production line for more than 20 years. There are two import lines in China

metal corner guards, box mouth clips, fixed accessories and hardware for box bottom and tray used for box reinforcement of heavy cardboard have been developed and improved abroad for 30 to 40 years. Octagonal clip gaskets and large square head self tightening screws patented in the United States in the 1950s are still used in some places

in addition, there are pulp molded pallets used as seats instead of wood packaging, and "paper mold" products as cushioning pads; Non polluting packaging uses low-grade corn starch foaming particles as buffer fillers, and high-tech equipment has been used in many countries
