Microwave ovens transfer energy primarily to water and other polar components in food. The resulting heat then moves into the container wall, coating, seal and lid. This is why the same package can behave differently with broth, rice, oily curry, sugary sauce or a frozen prepared meal. Container geometry also matters.

Heat-resistant normally means that a material can tolerate a stated food or service temperature for a defined period. This may describe hot filling, delivery holding or contact with soup, oil or sauce. It does not automatically address electromagnetic interaction, food hot spots, steam pressure, seal stability or repeated heating. Microwave-transparent means that microwave energy can pass through a material with relatively little direct absorption.
