1. Full PU Foam Insulation
The entire cooler is filled with high-density PU foam, delivering stronger and more stable insulation than hollow or partially filled designs.
2. Three-Layer Temperature-Locking Structure
A reinforced triple-layer system effectively reduces heat transfer, keeping food and beverages hot or cold for extended periods.
3. Thickened Foaming Layer for Long-Lasting Performance
A visibly thicker insulation layer enhances durability and maintains consistent temperature retention during daily or commercial use.
