Cushions, gussets, etc.
Since corrugated paperboard has a good cushioning property, it is used as cushioning material and insulation board for packaging, and its composite sandwich structure makes its buffering performance better than corrugated cardboard. When using it as a corner pad, it is generally necessary to cut a sheet of paperboard and core paper by size. Retaining only another layer of paper is not scratched, relying on this layer of paper to connect several pads of different sides together, and then cover the corresponding part of the contents to be protected. Similar to cushioning liners, corrugated composite paperboard can also be used as a gusset and protective edge for transport packages, which is particularly suitable for assembly packaging. Corrugated paperboard can also be stamped and molded to the device according to device dimensions to position the device.
Paper tray
Because the corrugated composite board has a good flat compressive performance, it can be fully used for the upper and lower decks in the pallet, and it can also be used as the stringer or pad of the pallet. At this time, according to the standard of the longitudinal beam or the pad, the size of the mattress is formed by several layers of thick corrugated cardboard, that is, the entire pallet is made of corrugated cardboard only.
Application of corrugated composite paperboard in construction The paperboard has high strength, light weight, heat insulation and sound insulation, and is particularly suitable for the production of construction, decorative materials and products. Its light weight can reduce the weight of the building, so it is particularly suitable for high-rise buildings with light-frame structures that are being promoted. At the same time, because of its good heat insulation and sound insulation, it can be made into walls, partitions, doors, etc. The relevant data shows that: At present, China's building materials, wall materials accounted for about 70%. The National Construction Committee has jointly issued a notice that, starting from June 1, 2000, the use of solid clay bricks in construction is prohibited, and the use of new wall materials is actively promoted. This creates a “corrugated composite honeycomb paperboard—gypsum†composite interior wall market. The conditions created a good external environment for the application of corrugated composite honeycomb paperboard in construction.
The application of corrugated composite paperboard in the funeral industry adopts low-cost corrugated composite honeycomb paperboard to produce "hygiene" suitable for one-time use, safety and health, and completely solves the problems of high turnover and unsanitaryness of "turnover". At the same time, "hygiene" adhesives use non-polluting starch glue to achieve the requirements of non-toxic, odorless and residue-free combustion.
Thin corrugated cardboard in agriculture
Single-layer panels can be used as an agricultural nursery trough. The use of such nursery troughs to raise seedlings indoors can not only solve the shortage of light, heat and water resources in agricultural production, but also enable the seedlings to avoid pests during the growth period, and they can be degraded during transplantation, unlike plastic bags, which cause environmental pollution. In addition, paper tubes and drums can also be used for breeding, nursery tools and flower pots.
The use of corrugated and composite cardboard and market forecast analysis of market demand: Take motorcycles as an example, China produces about 1oooo of motorcycles each year. If 75% of them use corrugated composite cardboard boxes, the consumption of 7m 2 will be required. Corrugated composite board 50 million square meters.
According to relevant experts' predictions, the potential market for corrugated honeycomb composite board is very large, and if it is used well in the construction industry, the demand is even greater. The production and application of corrugated honeycomb composite board will surely rise in China, and its market demand will exceed several hundred million square meters every year. Corrugated honeycomb composite board will be welcomed by users at a low price and excellent performance.
It is estimated that the export value of China's products will reach 100 billion U.S. dollars by the year of 2000, which is more than doubled in 2000. The quantity of containers needed for export products, and the demand for cushions and trays in relief products are staggering, with the increasing market economy and foreign trade. With the continuous development of consumer awareness of environmental protection and development, paper trays and substitute wood packaging boxes are favored. Packaging materials and packaging products such as corrugated paperboard are even more unstoppable.
At present, China consumes about 40 million to 50 million wood pallets each year. If about 50% are replaced with corrugated cardboard pallets, 20 million to 25 million will be needed. According to relevant foreign statistics, if corrugated composite cardboard is widely used in various industries such as packaging, construction, vehicle and ship transportation, furniture, agriculture, film and television, and display, social demand will at least increase by more than three times. Based on this ratio, it is conservatively estimated that at present, China needs at least about 100 million corrugated composite cardboard pallets. Coupled with the annual demand of around 150 million in Hong Kong, China’s current total demand will be around 250 million. Of course, compared with developed countries, China's demand for corrugated composite board is still relatively low. The annual demand in Japan is about 3.7 billion, the United States is about 800 million, and the EU is 7.3 billion. According to statistics, in 2000, the annual usage of trays in China was about 45 million. If all the corrugated cardboard were used instead of wood, 90% of the timber could be saved, 2/3 of the funds could be saved, and only 15% of this would be saved. Yuan funds. Moreover, the corrugated composite board can be recycled and recycled, which makes a significant contribution to the protection of forest resources and the maintenance of ecological balance.
Good social benefits
Corrugated composite board production technology has a wide range of social benefits and excellent economic benefits. Replacing wood packaging with corrugated paperboard packaging can save a lot of wood resources. Each ton of recycled corrugated composite paperboard can replace 30 to 50 cubic meters of wood: only mechanical and electrical products are packaged. If you can replace 1/3 each year, you can save 11 million cubic meters, more than 3 million cubic meters of raw wood, and can be recycled in large amounts of waste paper, recycling and disposal of discarded packaging. If according to experts' estimates, the annual production of corrugated composite board of several hundred million square meters can save millions of cubic meters of wood, creating a production value of several billion yuan, coupled with the reduction of packaging costs to promote the export of products, the social benefits can not be Estimated.
Non-top paperboard trays for extended applications of corrugated and composite paperboard
According to the requirements of domestic and export fruit and vegetable producers and consumers, the type and effect of packaging boxes still need to be improved. Driven by this demand, the close cooperation between corrugated board manufacturers and machine builders, such as Boix, has resulted in the production of topless cardboard pallets.
The main purpose of the development of non-top cardboard pallets is to produce a packaging tray with less consumption of cardboard and better resistance, which has been a great success. Due to its high strength and good air permeability, this cardboard tray can make the product better when it reaches the destination.
The wide variety of existing topless cardboard pallets are mostly patented by cardboard manufacturers, which requires the development of machines necessary for the production of such new types of cardboard pallets. This work can only be successful if the cardboard manufacturers and the machine manufacturers cooperate closely. Along with the introduction of the topless cardboard tray, its bottom dimensions are also standardized into four types: 60 X 40, 50 X 40, 40 X 30 and 30 X 20. All these dimensions are for easy handling with the 1 20 X 1OO or 1 20 X 80 standard carrier, making more efficient use of handling tools and storage space. This standardization requires a machine that produces cardboard pallets to produce a variety of standard, fine-sized cardboard pallets.
The new pallets made of standard structural corrugated board, like the garment design, can meet the user's special requirements for size, weight and shipping conditions. It includes rung spacing, top and bottom thickness variations, and coating applications. At present, due to environmental reasons, international transportation requirements do not use wooden pallets as much as possible, so the demand for corrugated cardboard pallets has grown rapidly and favored.
The use of corrugated paperboard trays can reduce transportation costs. A standard wooden pallet weighs about 27 kilograms while a paper pallet weighs only about 47 kilograms. This means that each truck can hold 850 kilograms of cargo and it is easy to carry. In addition, the paper tray has no slivers of trees, no fixed nails and rough corners, and no toxic chemicals left on the oak trays when fumigated, so it does not pollute the environment and harm the human body. And it can be recycled. It is easy to handle. Like all three-layer corrugated cardboard, the pallets are made of A-type corrugated, and the strength and weight ratio are appropriate. The three-layer corrugated cardboard tray is generally the same strength as the wooden tray, and weighs only 20% of the wooden tray.
