Grid plastic pallets, as the basic load-bearing tools in modern logistics systems, have become a key link connecting storage, transportation, and production processes with their unique structure and excellent performance. It is mainly made of HDPE (low pressure high-density polyethylene) or HDPP (low pressure high-density polypropylene) as raw materials, and is molded in one go through injection molding process. Its structure presents obvious grid like characteristics. According to the different bottom support structures, it can be subdivided into core categories such as Sichuan shaped, Tian shaped, nine legged, and double-sided. Different types are suitable for forklift operations, shelf storage, economic turnover, anti stacking of bagged goods and other diversified scenarios. It has been widely used in many industries such as medicine, food, papermaking, and chemical industry.
The performance advantage of this tray comes from its scientific design and high-quality materials. In terms of load-bearing capacity, some models can lift dynamic loads up to 1.5 tons and static loads up to 6 tons through built-in steel pipes. Double sided pallets can carry dynamic loads up to 1.5T, static loads up to 4.0-6.0T, and shelf loads up to 1.0T, while single-sided pallets can carry dynamic loads up to 1.2T, static loads up to 3.0-4.0T, and shelf loads up to 0.8-1.0T. Although the nine legged model is mainly economical and practical, it can also reach dynamic loads up to 0.5 tons and static loads up to 1.5 tons or more. At the same time, it has the characteristics of light weight, sturdy and durable. HDPE material brings good heat resistance, cold resistance and chemical stability, while HDPP performs well in strength and stiffness. In addition, the nail free and stab free design can not only avoid damage to goods but also ensure the safety of operators. It can also be recycled and reused, with a service life of 2-5 times that of turnover wooden pallets.
In practical application scenarios, grid plastic trays exhibit strong adaptability and efficiency. In the warehousing process, its standardized parameters can adapt to more than 80% of shelf systems, the four-way fork is compatible with mainstream handling equipment, the pallets with anti slip particles can effectively prevent goods from overturning, and the nine legged pallets can also be stacked for storage, saving 38% of storage space compared to the Sichuan shaped pallets; On the production line, the mesh hollow structure can prevent parts from getting damp and oxidized, and can quickly identify the status of lower level goods through stacking gaps, reducing the time for flipping and inspection. After being used by a certain automotive parts manufacturer, the production line error rate decreased by 40%; In special scenarios, customized mesh plastic trays can provide anti-static coatings or conductive inner layers to control the failure rate of electrostatic sensitive devices below 0.05 ‰, meeting special requirements such as precision instrument assembly.
Of course, grid plastic trays also have certain limitations, such as the grid structure being prone to accumulating dust, creating hygiene blind spots, and potentially damaging packaging bags under gravity. Additionally, their moisture resistance is not as good as flat plastic trays. But overall, its advantages far outweigh its shortcomings. With the development of the logistics industry, grid plastic pallets with built-in chips also demonstrate the potential for IoT integration. By binding RFID tags, real-time tracking of pallet position status can be achieved, increasing warehouse utilization by 22% and optimizing picking paths by over 35%. It is transforming from a simple carrying tool to a data terminal, providing strong support for the upgrade of intelligent warehousing.
