The birth of leak proof plastic trays marks the evolution of industrial containers from the steel age to the polymer age. By using modified polyethylene (PE) or polypropylene (PP) as the main material and incorporating additives such as anti UV agents and flame retardants through blending modification technology, traditional plastics can achieve metal grade load-bearing capacity (static load up to 8 tons) and ceramic like chemical inertness.
This material innovation not only retains the lightweight characteristics of plastic (weighing only one-third of steel pallets), but also breaks through the limitations of traditional plastics that are prone to aging and deformation.
Using the principle of surface tension control in fluid mechanics, liquid directional flow is achieved through a honeycomb shaped guide groove design (groove depth typically 8-12mm). When a leak occurs, over 90% of the liquid will be introduced into the bottom sealing layer within 30 seconds, and the remaining liquid will be adsorbed through an oleophilic polymer coating (contact angle ≤ 15 °). The surface grid achieves operational visibility, while the bottom sealing layer ensures zero escape of leaked substances;
Its structural design conforms to the principles of fractal geometry:
Macroscopic level: The "pot in pot" structure of overall injection molding forms a physical leak proof double insurance
At the meso level, a hexagonal honeycomb grid (with a porosity of 42% ± 3%) is used to achieve liquid directional flow guidance
Microscopic level: Surface micro level roughness treatment (Ra0.8-1.6 μ m) enhances anti slip performance
Environmental intelligent response
The new generation of products is evolving towards' thinking trays'. By embedding pressure sensing optical fibers (diameter 0.25mm) and pH detection chips, the physical and chemical properties of leaked substances can be sensed in real time, and the data can be uploaded to the cloud EHS management system through the LoRaWAN protocol, forming a complete closed loop from physical protection to digital supervision.
As a key component of modern industrial safety systems, the anti leakage tray is essentially a dynamic protection system that combines physical isolation with intelligent monitoring. This design upgrades traditional passive leak prevention equipment to intelligent terminals with environmental perception capabilities, which not only reflect its value in direct economic loss prevention, but also become an important data node in the enterprise's ESG management system.
