Isothermal constitution


COLD & CO’s Self-Inflating Thermal Wrap is a patented compressed thermal wrap technology. Delivered under vacuum, the self-inflating thermal envelope has a high density, high quality foam insulation. Before use, the opening tab of the vacuum compartment must be removed. The foam then regains its insulating thickness of 20mm. This technology is a real asset to optimise its transport and storage before use.

External construction: a robust shipping envelope

The outer coating of the self-inflating envelope guarantees a secure shipment. Designed with a white opaque film on the outside and black on the inside, COLD & CO’s self-inflating envelope ensures the confidentiality of your shipment. Its co-extruded coating makes the envelope waterproof and resistant to punctures, tears and breakage.



The self-inflatable isothermal envelope is easily closed with a flap with a definitive and tamper-proof self-adhesive closure.
