Main applications of stretched corrugated board

The application situation of corrugated and composite paperboard and its products in the packaging industry in China is mainly in the following aspects: slow, medium liners, paper trays and composite trays; gussets and ribs; other easing; middle structural parts, such as transportation The cushions, sandwiches, baffles and direct molding of the packaging or pallet packaging unit; middle structural parts, etc.; large-scale household electrical appliances, heavy-duty telecommunications products, and non-heavy-duty mechanical and electrical products. Slow; middle pads, gussets, etc.

Since corrugated paperboard has good easing, it can be used as cushioning material and insulation board for packaging, and its composite sandwich structure can make it slow. The introduction can be better than corrugated paperboard. 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 scratched, relying on this layer of paper to join together several pads of different sides, and then cover the corresponding part of the contents to be protected. Similar to the pad, the corrugated composite board can also be used as a gusset and a protective edge of a transport package, which is particularly suitable for assembly packaging. The corrugated board can also be dimensioned according to the device; medium pressure is molded 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 size of the longitudinal beam or pad, it is processed by several layers of thick corrugated cardboard, that is, the entire tray is only made of corrugated cardboard.

Application of Corrugated Composite Board in Construction

The cardboard has high strength, light weight, heat insulation and sound insulation, and is particularly suitable for making buildings, 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, due to its good heat insulation and sound insulation, salt walls, partitions and doors can be made. The relevant data shows that: At present, China's building materials, wall materials accounted for about 70%. The National Construction Commission has jointly issued a notice that, starting from June 1, 2000, solid clay bricks have been banned in construction and the use of new wall materials has been actively promoted. This has created the “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.

Application of Corrugated Composite Board in Funeral Industry

The use of low-cost corrugated composite honeycomb paperboard for the production of "hygiene" is suitable for one-time use, safety and health, and completely solved the problems of high turnover, unsanitary and other problems. 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.

Corrugated and composite board use and market forecast

Analysis of market demand: Take motorcycles as an example. China produces about 10 million motorcycles each year. If 75% of them use corrugated composite cardboard boxes, each with a dosage of 7 m2, 50 million square meters of corrugated composite board will be required.

According to relevant experts' forecasts, the potential market for corrugated honeycomb composite board is very large, and if it is used 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 by 2005 China’s product exports will reach 100 billion U.S. dollars, which is more than doubled in 2000, and its export products are required to be packed; the demand for liners and trays is staggering. With the market economy and foreign trade The ever-increasing development and increasing awareness of environmental protection by consumers have led to the popularity of paper trays and wood-based packaging boxes. 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 is about 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 370 million, the United States is about 800 million, and the European Union. 300 million. According to relevant statistics, in 2001, the annual usage of trays in China was about 45 million. If all the corrugated cardboard were used instead of wood, 90% of the wood and 2/3 of the funds could be saved. This alone can save 15 billion 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 board can replace 30 to 50 cubic meters of wood. Only one mechanical and electrical product package can replace 1/3 each year. 1.1 million cubic meters, or more than 3 million cubic meters of logs, and can recycle a large amount 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.
