Related paper tray words: storage cage, crates, wood pallets, steel pallets, cardboard, pulp molding wooden pallets, paper for Kok, pallets plastic pallets, shelf paper tray material in pulp, paperboard raw material processing and manufacturing of pallets. With the international market's increasing environmental packaging requirements, in order to achieve rapid clearance inspection requirements in order to achieve rapid logistics, Pallet manufacturers have successfully developed a high-strength paper tray. The main parameters: length / width / height / length and breadth error / diagonal error / rated load / maximum stacking layers / deflection / slip coefficient surface / water immersion time / humidity range characteristic use of the environment: the whole paper, high strength, specifications may vary customized. Purpose tray paper tray (Pallet) for container, stacking, handling and transportation of goods and place standard platform device as a unit load products. Usually made of wood, metal, fiber production, ease of handling, transport unit supplies and small quantities of material. The main types of wooden pallets, plastic, metal and other materials wood is now the most widely used, because of its cheap, strong; plastic tray more expensive point, the load is small, but with the progress of the manufacturing process of plastic pallets, Some high load of plastic pallets has emerged, is slowly replace wooden pallets. Durable metal tray, the disadvantage is corrosive, higher prices. Paper tray Classification 1: hexagonal honeycomb structure honeycomb paper tray is a masterpiece of bees, it consumes a minimum of material to build a nest rugged peaks, its structure has extraordinary scientific. Honeycomb honeycomb structure is modeled to paper as a substrate, with modern electromechanical unity to produce a honeycomb of new material. It is light weight, high strength, stiffness, and a buffer, vibration, thermal insulation, sound insulation properties. While its low cost and wide applicability, widely used in packaging, storage and transportation, construction, travel industry, the furniture industry, in order to replace wood, clay brick, expanded polystyrene (EPS), etc., to reduce deforestation and protect the ecological environment of great significance if the home is no paper tray, you can also use other paper tray. Use current situation of China Federation of Logistics and Purchasing Pallet Professional Committee in September 2002 in Beijing, Tianjin, Shanghai, Guangzhou and four cities in more than 300 production, transportation, storage and distribution companies were surveyed tray from the status quo, existing and how to solve the problem and other aspects of China's use of specific tray understanding and analysis, this work will help strengthen the coordination of the pallet industry and guidance, but also for the logistics management and related businesses to provide valuable information and recommendations . (1) The preliminary investigation of existing materials tray China Federation of Logistics and Purchasing Pallet Professional Committee show: China now has various types of pallets about 5000 million to 7000 million, the annual output of about 20 million increments. Which accounts for about 90% of flat pallets of wood, plastic flat tray 8%, steel tray, the complex composite material tray tray tray and paper together accounted for 2%. Composite flat pallets and plastic pallets large proportion of the rise. (2) The main specifications of China tray and the tray currently existing, China pallet specifications rather confusing. In addition to the machinery industry system JB3003-81 prescribed 800 mm × 1 000 mm and 500mm ~ 800 mm two specifications tray, 1996, Chinese Research Academy of the Ministry of Transportation has proposed to ISO6780: 1988 "General intermodal flat pallets and main dimensions Tolerance "is equivalent to using the national standard for the Chinese tray. Later, the former State Bureau of Technical Supervision to GB / T2934-1996 standard series Symbol approved and published this equivalent standards, including the 1 200mm × l 000mm, l 200mm × 800mm, 1 140mm × l 140mm and 1 219mm × l 016mm 4 trays and other specifications. In addition, with regard to tray standard, China still has GB / T3716-2000 tray term, GB / T 16470-1996 tray packaging, GB / T15234-1994 plastic flat tray, GB / T4995-1996 transport general flat pallets performance requirements, GB / T4996 --1996 transport general test methods for flat pallets and other national standards. Moreover, the Japanese in China, and also a large number of Korean enterprises use the l 100mm × 1 100mm specifications of the tray. All these are described tray standard adopted by many Chinese as not to rectify, it is difficult to effectively address the question of reunification Chinese tray specifications. According Pallet Professional Committee investigation found that the current circulation tray specifications messy. Including: 2000mm × 1 000m tray m, 1 500mm × 1 100mm, 1 500 mm × 1 000 mm, 1 400 mm × 1 200 mm, 1 300mm × 1 000 mm, l 200 mm × 1 000 mm, 1 200 mm × 800mm, l 200 mm × 1 100 mm, 1 100 mm × l 000 mm, 1 100mm × 1 100 mm, 1 100 mm × 900 mm, l 000 mm × 1 000mm, l 000 mm × 800 mm, l 200 mm × l 200 mm, l 300mm × l 600mm, l 300mm × l 100mm and dozens of kinds of specifications. Wherein the plastic tray specification is relatively concentrated, mainly 1 100mm × 1 100 mm and 1 200 mm × 1 000 mm, accounting for about 50% of the plastic pallets. This is due to the production of plastic pallets to be used in injection mold, and mold development costs are relatively high. Wooden pallets specifications chaotic, the current specification is mainly the use of units according to custom specifications of their products, which is a wooden pallet manufacturing process is relatively simple and relevant. Steel tray specifications are not many, concentrated in two to three specifications, mainly used for carrying the weight of the tray is relatively high in ports and other units. Also pallet professional committee also found in the survey, companies now use mostly flat four-way fork-sided pallets, accounting for about 60% of the total use of the tray. The rest of the plane as well as the use of two-way fork into the duplex tray, use a flat-sided pallet, box pallets and Column tray. Use of special tray number is relatively small. Box-type tray is now used for the production process, material handling, basically does not enter the circulation. Statistics (3) Working way Pallet Professional Committee indicate, at this stage Chinese pallets in use is basically the internal turnover. For manufacturers, it has no business pallets, use of the tray is limited to transport from the enterprise warehouse to transport links between. For logistics companies, the tray can use to deploy within the enterprise, there is no mechanism for the formation of a smooth flow of pallets. (4) the development of the job situation tray tray can be said synchronized with forklift. Forklift and pallet together to form an effective handling system that allows loading and unloading efficiency is greatly improved. From a statistical perspective, the current tray is basically used with forklifts. Each truck is equipped with an average of 800 to 1000 trays.
