Principle
Two Parallel Walls: In a plastic cooler box with a double-wall structure, there are two primary walls: an inner wall and an outer wall. These walls are typically made of the same or similar plastic material, forming the exterior and interior layers of the cooler.
Air Gap: Between the inner and outer walls, there is an air gap, also known as an insulation gap. This gap can vary in width, but it is typically designed to be small and uniform, ensuring a consistent insulating barrier.
Thermal Insulation: The air in the gap serves as a thermal insulator. Air is a poor conductor of heat, and by trapping it between the walls, the double-wall structure prevents the transfer of heat through conduction.
Reduction of Heat Transfer: Heat transfer occurs through conduction, convection, and radiation. In the case of double-wall insulation:
1) Standard packaging: Platic bag+carton box;
2)Customized packaging is acceptable. Pls let us know if you have any special packaging requirment.
