The self-inflating thermal envelopes arrive in patented large compression sleeves (pictured) and inflate when removed from the sleeve. These thermal mailers are made using a Mylar outer cover (an added benefit over non-reflective inflatable insulated pouches) and a high-performance polyurethane insulated panel offering unmatched insulation as well as excellent cushioning, shock and vibration protection.

The thermal pouches could not be simpler to use. Simply fill them up with your temperature-sensitive goods, and seal it up with the peel-and-seal adhesive strip.
