There are three types of heat transfer.
Conduction
Convection
Radiant
Thermal energy is transfered from hot to cold. (cold technically being the absence of heat).
Conduction: Plastic is not a good conductor of heat. Think of the plastic handle on a metal pot. The plastic material of bubble wrap (ignoring the bubble part) helps prevent the transfer of heat.
Convection: The small air bubbles do not allow the circulating air currents that provide convection heat transfer. A difference in temperature across an air pocket allows air movement. Imagine how hot air rising and then cooling off and sinking down the other side of the void. The large "air pillows" used for packing material in shipping have big air pockets that will allow more convective heat transfer.
Radiant: Foil backed bubble wrap helps prevent radiant heat transfer. Or just wrap aluminum foil around the side of the container that will be hotter. Are you trying to keep something hot or cold? That will define which side gets the foil.
All in all the lightweight bubble wrap is a great product to help prevent the transfer of heat.
