Abstract

Packages for foodstuffs include a heating device, which may comprises the base (2) of the package. The heating device comprises a pattern made up of elongate elements (8) of an electrically conductive material, such as aluminium. The pattern is applied to the substrate by a hot foil stamping process. Alternative configurations for the pattern are possible, for example the elongate elements (8) may be arranged in a radial manner. The elongate elements (8) are heated in the presence of microwaves, to assist crisping or browning of foodstuffs in the package when cooked in a microwave oven.
