Current situation of the development of wood packa

  • Detail

Development status of wood packaging for China's export commodities

at present, the annual consumption of wood used for packaging in China is about 5 ~ 8 million cubic meters. In the packaging of export commodities, the utilization rate of wooden cases is 23.8%. If wooden chassis, pallets, bedding and fixing materials are added, nearly half of China's export commodities at this stage use wooden packaging directly or indirectly. In 2002, China's exports of more than 100 billion US dollars directly or indirectly used wooden packaging. These commodities involve electromechanical instruments, hardware tools, chemical products, ceramic glass products and some agricultural and sideline products. The main export countries and regions include the United States, the European Union, Germany, Canada, Japan, Australia and Southeast Asia. They involve a wide range of commodities and many export countries, which has a significant impact on China's foreign trade exports

types and origin of wood packaging materials

wood packaging materials for export commodities are mainly divided into two categories: natural wood and man-made wood. Natural wood mainly includes coniferous wood (Korean pine, white pine, larch, masson pine, etc.), broad-leaved wood (poplar, elm, birch, oak, etc.); Artificial wood includes medium density fiberboard, particleboard, plywood, etc. Natural wood is mainly concentrated in the northeast, South China, southwest and other major forest areas, and some pine trees are imported from North America and other regions; Artificial wood is basically produced domestically. According to the survey, the wood pest Anoplophora glabripennis in China is mainly distributed in eight provinces in North China, central China and Northwest China. The main favorite hosts are poplar, willow, elm and maple, while the others are not parasitic species. At present, ordinary wooden cases and small wooden cases used for export commodities have low strength requirements due to their small packing weight. Therefore, in addition to the main components of coniferous wood such as larch, broad-leaved wood such as poplar is basically used. Due to the large volume, heavy storage and high strength requirements of large wooden cases, frame wooden cases and large wooden chassis, pine and other coniferous wood are basically used in all parts of the packaging. In addition, wood pallets, wood matting and fixing materials are messy, mainly poplar and other broad-leaved wood and various hard miscellaneous wood. From the above situation, the inspection and quarantine treatment of wood packaging for export commodities focuses on small wooden boxes, wooden pallets, wooden matting and fixing materials processed with broad-leaved wood

supply channel of wood packaging materials

with the opening of the market, as the main packaging material, the supply channel of wood has also changed from a single form to a multiple form. Small collective or individual timber operators have flocked, and they have become the main body of the timber market, at least in Beijing, and there are at least hundreds of such timber merchants around the third ring road. Of course, this has brought convenience and benefits to wood demanders. People can choose to purchase, the service attitude is relatively good, and the price is much cheaper than that in the monopoly period. At the same time, we also feel that it is difficult to control the quality of wood due to irregular market competition. For example, it is almost impossible to purchase qualified specification wood in the market, and more than 90% of the dealers sell specification wood whose section size is 5 ~ 10 cm smaller than the nominal size. Another example: in the individual market, except for imported wood, almost 100% of all dried wood is smoked fake dried wood, and the moisture content of these wood is generally high. Because these woods have not been treated, the pests and diseases carried in them must not be disassembled. In fact, metal objects and sandpaper must not be used to wipe the surface of the experimental machine, which cannot be effectively controlled or eliminated. These packing boxes carrying diseases and pests flow around, which has hidden dangers of expanding or transferring the epidemic area of forest diseases and pests

in addition, because most Timber Merchants directly transport logs from forest areas to large and medium-sized cities and then process them into specification timber for sale, all kinds of leftover materials are transferred from forest areas to cities. This process not only caused the waste of national transportation capacity and forest resources, but also made the already heavy urban environmental problems more serious. China is a country that is not rich in forest resources, but the wood scraps that could have been further processed and utilized have become garbage that destroys the environment

status of wood packaging production enterprises for export commodities

according to incomplete statistics, China's existing wood packaging industry for export commodities is also one of the three largest tomato production and processing countries in the world, with nearly 1000 industrial enterprises. The vast majority of these enterprises are small enterprises with less than 500 people, some of which are township enterprises and private enterprises. The enterprises are small-scale, with an annual output value of 2-3 million yuan generally, and a few annual output values of more than 5 million yuan. Most of these enterprises are semi mechanized and semi manual production, and the main processing equipment is band saw, cutting saw, press planer, plane planer, etc. a few enterprises have drying facilities. Due to the simple processing technology and poor production conditions, such enterprises are obviously inferior to other types of packaging enterprises in terms of personnel quality, automatic production level, management level and product quality

inspection and supervision of wood packaging for export commodities

according to the provisions of the commodity inspection law, the original commodity inspection and quarantine institutions have implemented the export packaging quality license management on the wooden packaging containers for export commodities listed in the statutory inspection category table since 1991, and the relevant wood packaging production enterprises have begun to establish a quality assurance system, and according to the characteristics of wood packaging, they have focused on strengthening the purchase and selection of raw materials The control of the three links of packaging structure design and finished product assembly basically achieves the frost resistance. The material selection is excellent, the structure is reasonable, and the assembly is firm. On the basis of the qualified factory inspection of the production enterprise, the original commodity inspection authority will carry out the inspection before the packaging leaves the factory. The main inspection items include appearance items such as structure, materials, materials, process processing, and strength items such as falling, lifting, stacking, and bearing. Enterprises with stable quality and continuous production will be subject to synchronous inspection, and enterprises that have not yet formed continuous production will be subject to batch by batch inspection. Therefore, the wood packaging containers for export commodities listed in the category list are of good quality as a whole, while the wood packaging and wooden pallets for export commodities not listed in the category list have certain problems in material selection, structural design, processing quality and so on due to the lack of strict and systematic management. In particular, wooden pallets, most of which use poplar as planking and hard miscellaneous wood as longitudinal beams, have adverse phenomena such as uneven planking thickness, many burrs, serious mildew, dead joints and insect eyes exceeding the standard

due to the small scale and small production batch of wood packaging enterprises for export commodities, the original commodity inspection and quarantine institutions once relaxed the license management, resulting in some enterprises producing without licenses. Since the United States put forward strict quarantine requirements for China's export commodity wood packaging in October 1998, the State Administration for entry exit inspection and Quarantine has required local inspection and quarantine institutions to implement strict license management for export commodity wood packaging production enterprises, including enterprises that produce and use their own products, and added conditions and requirements for quarantine and quarantine treatment to the contents of assessment and review, It is emphasized that production enterprises must print packaging marks on wood packages that have passed the inspection and quarantine

comparison between wood packaging of bamboo powder moisture volatile products of exporters and imported commodity wood packaging

imported commodity wood packaging mainly includes standard wooden cases and pallets, which are generally used to hold electromechanical instruments and other valuable commodities. From the overall situation, its appearance and strength quality are significantly better than that of China's export commodity wood packaging. Pine is generally used as the main stress components, and multilayer wood plywood is mostly used as the box board and bedding. The utilization rate of artificial wood is much higher than that of China's export wood packaging. In comparison, the quality of EU and Germany is the best, followed by the United States and Canada, followed by Italy, Japan, Southeast Asia, Taiwan and Hong Kong. Although the appearance and strength quality of imported wood packaging are better than that of exported wood packaging in China, there are also serious pest problems. From 1998 to October 1999, Chinese inspection and quarantine institutions intercepted pine wood nematode batches from coniferous wood packaging from the United States and Japan for as many as 44 times and 28 times respectively. Recently, Jiangsu inspection and quarantine department intercepted a large number of live termites from the wooden packages of machinery and equipment imported from the United States. In order to prevent pine wood nematodes and other wood packaging from entering China, the Chinese government issued an announcement on November 1st, 1999, stipulating that strict quarantine requirements should be adopted for wood packaging in the United States and Japan from January 1st, 2000. If the wood packaging is made of coniferous wood, it must be heat treated before leaving China, and its official organization should issue a certificate
