1. A packaging device comprising:
a multi-layer material configured to define an interior space and an opening to the interior space, wherein at least a portion of the multi-layer material comprises:
an inner layer made of a first biodegradable material;
an outer layer made of a second biodegradable material;
a heat-activated expanding foam disposed between the inner layer and the outer layer, wherein the heat-activated expanding foam comprises thermoplastic beads containing low boiling point hydrocarbon; and
a heating element layer encapsulated between the inner and outer layers, wherein the heating element layer is biodegradable and provides resistive heating to the interior space when supplied with electrical power from a power source; and
a coil electrically connected to the heating element layer and configured for inductively coupling with an external power source to provide the electrical power to the heating element layer.
