What are the best practices for preventing warpage in WPC outdoor trash cans during storage?

Preventing warpage in Wood Plastic Composite (WPC) outdoor trash cans during storage requires careful attention to environmental conditions and handling practices. The best practices begin with proper positioning - always store WPC trash cans on a flat, level surface to distribute weight evenly and prevent uneven stress that causes warping. Avoid storing bins on uneven ground or surfaces that slope. Temperature control is crucial since WPC materials can expand and contract with temperature fluctuations. Store your trash cans in shaded areas away from direct sunlight and extreme heat sources, as prolonged exposure to high temperatures can soften the material and make it prone to deformation. For long-term storage, avoid stacking multiple trash cans unless they're specifically designed for stacking, and if you must stack, place protective padding between units. Ensure the trash cans are completely clean and dry before storage to prevent moisture buildup that could lead to material degradation. Rotate the bins periodically if storing for extended periods to prevent continuous pressure on the same points. Additionally, consider using breathable covers that allow air circulation while protecting from dust and debris. Following these practices will help maintain the structural integrity and appearance of your WPC outdoor trash cans throughout their storage period.
