Since the United States and the European Union imposed restrictions on wood packaging for the US and Europe shipments in the second half of the previous year, the honeycomb paperboard was pushed to the front desk. The billion-dollar packaging industry, especially paper packaging workers, is deeply concerned about this. This is a gratifying thing.
A corrugated paperboard and honeycomb paperboard corrugated paperboard and honeycomb paperboard both use paper as the basic material, and are two types of doors with different structures. Corrugated cardboard is a corrugated structure, divided into single corrugated cardboard, double corrugated cardboard and three corrugated corrugated cardboard, and was invented in 1856. At that time, corrugated paper was used to pack light bulbs. By 1920, double corrugated paperboard came out, with a speed of 6m/min and a width of 800mm. Now it has reached a speed of 350m/min and a width of 4500mm. It is a stand-alone, single-sided machine to the production line. Corrugated cardboard is used to make corrugated cartons for transport packaging and corrugated cartons for sale and packaging. Honeycomb paperboard is an upright honeycomb structure. The paperboard is made of two layers of paper and an intermediate honeycomb paper core glued together. There is no sandwich. It is divided into metal honeycomb and non-metal honeycomb structure, metal honeycomb mainly refers to aluminum honeycomb, and non-metal honeycomb is mainly paper honeycomb. Honeycomb structure products appeared during the Second World War in the 1940s. Confucius only had an aluminum honeycomb sandwich structure for the lightweight parts of the radio. In the 1950s, the United Kingdom first promoted cellular composite materials to civilian use and spread it to countries such as Europe and the United States. The Netherlands introduced the paper honeycomb core earlier. In the 1960s, China began to introduce honeycomb structure production technology and applied it to aviation and aerospace fields. In the 1990s, honeycomb paper products entered China, and people of insight took the lead in the development of honeycomb paperboard forming equipment with a machine speed of 12m/min, a range of 1600mm, and a thickness of 5mm. -4mm, honeycomb side length 6mm-12mm.
Honeycomb paperboard is another new type of packaging paperboard substrate after corrugated paperboard 100 years ago. Its birth was another revolution in paper packaging, which added a new member to the paper packaging family.
Then, can honeycomb paperboard completely replace corrugated cardboard? The answer is no. The main purpose is not the same. Paper packaging was originally packaged in sheet-fed paper and invented in the Tang Dynasty in China. It was used to package candy, porcelain, and medicine. It was then made of cardboard and fixed in a carton box containing jewelry, gold and silver jewelry, and then corrugated cardboard and corrugated boxes. Although its role is outstanding and the proportion of usage is large, paper and cardboard are not eliminated. The same honeycomb cardboard is added to the big family of paper packaging, and it can only play its part. For example, the maximum weight of a single corrugated box is 40kg, and the maximum overall size is 2000mm (sum of length, width and height); the maximum weight of double corrugated box is 55kg and the maximum overall size is 2500mm. The honeycomb carton far exceeds the weight limit of the “waist” box and can even prosper one or two tons of cargo. The maximum capacity size can be achieved for making honeycomb containers. However, it is not necessary or possible to completely replace corrugated cardboard. It is not conceivable to use honeycomb paperboard instead of corrugated cardboard boxes to form a large horse-drawn cart. It should be said that honeycomb paperboard and corrugated paperboard have their own advantages and disadvantages.
Second, they have different limitations. The pressure resistance of the honeycomb paperboard plane is several times to 20 times higher than double corrugated cardboard, and the puncture strength is not better than corrugated paperboard. The honeycomb paperboard core having a thickness of 10 mm has a slightly smaller or substantially equal amount of paper as the AB crucible. The thicker the honeycomb paperboard, the larger the side length, the less the amount of paper used, but the thickness of the 5mmA type single-brick core paper is 1.53m2, and the same amount of the 5mm honeycomb paper is 1.8m2, which is more than the former. The speed of cardboard manufacturing varies widely. The corrugated board line is 350m/min, and the honeycomb paperboard line is 12m/min, which is one-thirtieth of the former. It can be seen that corrugated cardboard and honeycomb paperboard will exist side by side.
The use of two honeycomb paperboard features The use of honeycomb paperboard is very extensive. If corrugated cardboard is only used for packaging, most of them are made into corrugated cardboard boxes or corrugated paper boxes, and honeycomb paperboard is used for packaging less than 40%. Partially combined with other materials used in architectural doors, non-load-bearing inner partitions, half-walled, interiors and mobile homes; tabletops, beds, bookcases, shoes racks used in furniture production; used in transportation Made into trays, inserts, and other areas of billboards, exhibition boards, display racks, clean blackboards, funerals, and childbirth. However, it is the first thing we need to consider when it comes to packaging. In addition to being made into a tray in combination with transportation, it can be used as a heavy-weight packaging box to hold electric motors, auto parts, and aluminum products; it can be used as a fragile commodity packaging and ceramics. Tubes, arts and crafts, glass products, lamps and lanterns; to do large-scale packaging, tubs, motorcycles, home appliances, electronic equipment, medical equipment, computer containers; to do hygienic packaging, food, drugs, and irregular opening products, instead of EPS Cushions, grids, dividers, etc. The use of honeycomb paperboard in packaging is basically clear, and its improvement in paper packaging has brought good news. Recently, the National Packaging Improvement Office’s “Opinions on Strengthening National Packaging Improvement Work” pointed out that first, we must solve the problem of product damage, and second, we must solve the problem of waste pollution. Because of the special function of honeycomb paperboard, it can be used in flat glass, sanitary wares and export machinery and electronic products that will improve the packaging of key 8 types of products in the future. It is superior to corrugated boxes through rolling and dropping tests, and the damage rate of products is extremely low or destroyed. .
Secondly, to solve the pollution problem, honeycomb paperboard is an ideal green packaging material. It can be recycled without pollution, and can replace the WPS cushion liner in electrical goods packaging instead of wooden pallets. The pallets made of honeycomb paperboard in China have been approved by the United States and Europe at the end of 1998, which verifies the feasibility of this new product.
Many features of honeycomb paperboard are similar to those of corrugated cardboard. Its light weight, low price, material saving, easy recycling, and no pollution to the environment. It also has its unique place. It has higher strength than corrugated cardboard. It not only has 20 times higher flat compressive strength, but also has higher longitudinal strength. With large bearing capacity, 10mm honeycomb paperboard has the same hole moment with a load capacity of 0.5-12T/m2; it is less corrugated. Excellent cardboard protection performance, good elasticity, high cushioning performance, strong seismic performance. The more important feature is the saving of materials, the production of more than 10mm thick sheet, the minimum amount of paper used in honeycomb paperboard. Because honeycomb paperboard is based on the principle of bionics, made of honeycomb structure. Bee nests use the least amount of beeswax, and the thickness of the beeswax partition on each side is less than 0.1mm, resulting in a nest with the largest area of ​​the regular hexagon. Therefore, we do not choose triangles, squares or other shapes when selecting column pillars. It is preferred to take vertical and parallel six-sided cylinders, and the geometric angle between the walls is 120 degrees. The reason is to choose the honeycomb with the least material, the largest area, and the strongest tolerance.
In addition, it can be composited with a variety of materials made of honeycomb composite panels. Such as: with aluminum (plastic) into a paper honeycomb aluminum (plastic) plate, and fiber into a paper honeycomb fiberboard, and gypsum compound into a paper honeycomb gypsum board, but also with plywood, Polaroid and other composite.
In a word, compared with corrugated paperboard, honeycomb paperboard can be used in construction, furniture, transportation and other fields in addition to packaging materials. It shows many characteristics and has been gradually accepted by people. Production Status of Three Honeycomb Paperboard China's corrugated paperboard production line introduced three production lines in Tengtian and Neida from Japan in the late 1970s. In the 1980s, there were 10 professional fixed-point manufacturers. After 20 years, there are more than 1,000 “tile lines” in the country today. , the world's first, domestic "wattage" manufacturing capacity, the annual output of more than 200, and the more the better the build, in the past from the hydraulic support, computer cutting, vacuum adsorption on the eye, is now automatic paper, non-stop replacement specifications, automatic Change the tile roller, central computer control and walk towards wide and high speed. Carton equipment tends to be automated, multi-functional, and continuous production, and four-color ink-and-ink printing machines have attracted widespread attention. The corrugated board production line has become more and more mature, and manufacturers are learning from each other and competing with each other. Although the honeycomb paperboard production line has a history of 30 to 40 years abroad, it seems as if the technology blockade has just emerged. In the early 1990s, China installed the first manufacturer in Beijing, and started on the basis of self-reliance. By the end of the 1990s, Huangyang and Ruian, Xi’an, and Huangyan, which had passed the provincial and ministerial level appraisal, had successively manufactured cellular production lines. Other regions such as Guangdong Shunde, Zhaoqing, and Shenzhen are also eager to try. After the scramble, single or simple cellular product manufacturers are also among them. In the future, there will only be big waves and high quality wins.
There are basically two kinds of honeycomb paperboard manufacturing methods in China, one is a winding type and the other is a stacked type. Strictly speaking, our country's honeycomb paperboard production line has not yet reached the continuous production of single machines and systems from all the processes from paper feeding to board-out, and it can only become a honeycomb core production line and a honeycomb manufacturing line. At present, only Xi'an connects the manufacturing of cores with the board making line, but the speed is relatively slow and no climate has yet been formed. In short, China's "bee line" is not high at the level of design and craftsmanship. It is only at the primary or middle level development stage of honeycomb paperboard. To achieve the mid-level world level in the 1980s remains to be further improved, improved and improved.
At present, China's honeycomb paperboard manufacturers, including self-made simple "bee lines" and stand-alone machines, and about 80 paper-core manufacturing boards, have just begun to use in the packaging and storage of military materials, and later spread to civilian use. It was a manufacturer in the Dalian Economic Development Zone. Until 1998, the United States restricted the entry of wooden pallets, and it only launched the honeycomb paperboard. The successful export of paper pallets instead of wood pallets was widely recognized.
At present, there are fewer kinds of honeycomb paperboard products, which are used in packaging. There is no uniform form for “bee plate” boxes, and there is no complete series of box making machinery. In some “beehives”, manual operations are still used, and Wang may complete mass production. The manufacturing of honeycomb paper trays is also hand-cutting and affixing. The amount of orders is still small, but when the quantity is large, it is impossible to engage in "human sea tactics". It is also hand-glued after it is molded by a circular die-cutting machine. Furniture and doors are still hand-bonded and planed. The number of categories that have been developed is already so many. We also use manual work to single-make a variety, imagine how full the task is, and how to quickly win the trust of the market. It urges our packaging technology workers to participate in the cooperation, support it vigorously, and jointly develop this virgin land that has not yet been fully exploited.
The development prospect of the four-honeycomb paperboard During the development of the honeycomb paperboard, relevant government departments have made policy provisions in many aspects such as honeycomb paper boxes, walls, trays, and hygiene. It will certainly promote the rapid development of honeycomb paperboard.
On the honeycomb carton, the draft of the “Research on China's Green Packaging Development Strategies and Planning” prepared by the State Council pointed out that “this new kind of honeycomb cardboard box will become the ideal packaging for China’s export commodities, and its promotion and application will reduce the circulation of commodities in China. The rate of damage in the product plays an active role in improving the quality of packaged products.” In the relevant circular, the State Economic and Trade Commission again emphasized the need to accelerate the development and promotion of honeycomb paperboard and gradually replace some of the wooden box packaging. According to the market forecast, the motorcycle output will be 10 million vehicles per year, 75% will be packed in beehives, and 20 “bee lines” will be needed; the output value of mechanical and electrical products will be 800 billion per year; if the packaging value accounts for 3%, it will be packed in 10% “beehives”. Requires 25 “bee line” supplies; electronic products require 50 “bee line” supplies; glass and ceramics also require 30 “bee line” supplies; only one box must have more than 200 'bee lines to meet need.
In the construction, the National Construction Commission and other joint notices, from June 1, 2000, new houses in large and medium-sized cities in provinces, gradually forbid the use of solid clay bricks, and actively promote the application of new wall materials, to open the wall of paper honeycomb gypsum board Road. It is estimated that in the future, the use of paper honeycomb composite materials will reach 400 million square meters per year when used in buildings, and 240 “bee lines” will be required for a city of 2.3 million square meters per year.
On the transportation pallets, the State Economic and Trade Commission issued an emergency notice on issues related to the delivery of American goods and improved packaging, and called for "actively promoting the upgrading and replacement of wooden packaging, and encouraging enterprises to adopt economical and affordable new packaging materials." Now the port has wood (fumigated), steel, and plastic pallets. After the export of wooden pallets is restricted, honeycomb cardboard pallets, bamboo pallets, plywood pallets, corrugated cardboard pallets, and fiberboard pallets appear. The honeycomb paperboard tray has greater advantages in terms of saving wood, price, and environmental protection. If the port pallets need 35 million per year, and 50% of them are made of honeycomb paperboard, they must also have 20 “bee line” supplies.
In terms of hygiene and other aspects, Guangdong Province has explicitly stipulated that from April 1, 2000, it is forbidden to use wood clams in the remains of cremation. At the same time, the use of eco-friendly paper clams will be promoted throughout the province. The natural mortality rate of our country is 6 years, cremation 2
