In the field of logistics transportation, plastic pallets may seem ordinary but play a crucial role. A cross-border e-commerce enterprise once caused damage to the transportation of precision instruments worth millions due to improper selection of pallets, which highlights the importance of scientific selection. This article will break down the five core elements of plastic tray selection from a professional perspective, helping you make accurate decisions.
High density polyethylene (HDPE) and polypropylene (PP) are mainstream materials, but their performance differences are significant. HDPE exhibits stable performance in low-temperature environments, with an impact strength of up to 60kJ/m ², making it suitable for cold chain logistics scenarios; PP material maintains shape stability even at high temperatures, with a bending modulus of 1500MPa, making it more suitable for use in high-temperature workshops. Food grade materials need to pass FDA certification, and the pharmaceutical industry should choose medical grade anti-static materials with surface resistance controlled within the range of 10 ^ 6-10 ^ 9 Ω.
The ratio of dynamic load to static load is usually 1:4, and the usage scenario should be clearly defined when selecting. The Sichuan style structure forklift has the best adaptability, allowing for a pallet with two-way forks to increase operational efficiency by 60%. The bending strength of the T-shaped bottom plate is 45% higher than that of the nine legged type, making it suitable for storing 5-ton heavy-duty shelves. The anti slip strip design can reduce the sliding coefficient of goods to below 0.15, and smart pallets embedded with RFID chips can be selected for special industries.
The international standard tray size of 1.2m × 1m matches 95% with ISO containers, but actual selection needs to consider reserving 8-10cm of operating space for shelf crossbeam spacing. The height error of double-sided pallets should be controlled within ± 1.5mm, and special attention should be paid to the clearance between the pallet legs and the crossbeam for embedded shelves. Cross border e-commerce companies are advised to choose pallets with nested designs, which can save 75% of space when transporting empty boxes.
The initial cost of new material trays is 40% higher than that of recycled materials, but their service life can reach 8-10 years, which is three times that of recycled material trays. A tray with a repairable design can reduce maintenance costs by 30%, and a modular structure allows for separate replacement of damaged parts. It is recommended to establish a pallet lifecycle management system, which can trace the usage and maintenance history of each pallet through a QR code.
From the perspective of supply chain optimization, the selection decision of plastic pallets directly affects 15% of logistics efficiency and 20% of warehousing costs. A certain automotive parts manufacturer has increased the turnover rate of pallets to 28 times per year and reduced the damage rate from 12% to 3% through scientific selection. It is recommended that enterprises establish a standardized management system for pallets and combine IoT technology to achieve full cycle management of pallet assets, so that this logistics cornerstone can truly play a role in reducing costs and increasing efficiency.
