Abstract

A microwave energy interactive structure includes a layer of indium tin oxide, which may be supported on a microwave energy transparent substrate. In one embodiment, the microwave energy interactive structure may have at least one of an oxygen transmission rate of less than about 0.05 cc/m2/day and a water vapor transmission rate of less than about 0.09 g/m2/day.
