What Are Thermal Shipping Covers?
Thermal shipping covers—also known as thermal pallet covers, insulated blankets or cargo sleeves—are specialized protective blankets designed to wrap around pallets or containers. They use materials with low thermal conductivity and high reflectivity to limit heat transfer. The primary function is to create a micro-climate around the goods, shielding them from external temperature swings during transportation and handling. Unlike active refrigeration units, covers are passive. They do not require power or complex installation, making them flexible and cost-effective.
How Thermal Covers Work
Thermal covers typically consist of several layers:
Outer reflective layer: Often made of aluminum or metallized polyester, this layer reflects radiant heat from sunlight or nearby heat sources.
Insulating core: Common cores include air-bubble films, closed-cell foams or multiple paper layers. These materials trap air pockets to slow conduction and convection.
Optional vapor barrier: Some covers include a vapor-resistant layer to prevent moisture condensation, which can damage goods or compromise insulation.
By combining reflectivity with insulation, thermal covers reduce the rate at which external temperatures penetrate the cargo. When properly installed, they maintain stable temperatures during transit and handling.
