A heat shrinkable film useful for packaging and for cooking in a microwave oven of at least one food item which requires surface browning or crisping, comprising (a) at least one layer of flexible, heat resistant, microwave transparent base film which exhibits shrinkage of at least about 10% when heated unrestrained to 100°C. for 5 seconds, and (b) at least one partially transmissive layer of microwave susceptor material extending over at least a portion of the base film and present in an amount sufficient to cause the film to heat under microwave cooking conditions to a temperature suitable for browning or crisping of a food item placed adjacent thereto. The heat shrinkable film of claim 1 wherein the susceptor material is a substantially continuous layer of metal of appropriate thickness to cause the film to heat. The heat shrinkable film of claim 5 wherein the thickness of the layer of metal is sufficient to provide a resistivity of about 60 to about 1000 ohms/square.
