New 40ft High Cube Thickened Foam Insulation Container

The outer shell of the insulated box is generally made of high-strength, impact-resistant materials such as plastic and metal to provide good protection and support. Common plastic shells have the advantages of light weight and corrosion resistance, while metal shells are more sturdy and durable. The insulation layer is the core part of the insulated box and is usually filled with insulation materials. Common insulation materials include polystyrene foam (EPS), polyurethane foam (PU), perlite, etc. These materials have low thermal conductivity and can effectively reduce heat transfer, thereby achieving the effect of insulation. The inner liner of the insulated container is generally made of food-grade plastic or stainless steel, which has good hygiene and corrosion resistance and can directly contact food or other items that need to be insulated.
