Abstract: A laminated wrap for packaging articles of food requiring browning and crispening and a degree of shielding during microwave cooking is disclosed. The wrap comprises a layer of flexible, heat resistant, microwave transparent plastic film, a layer of flexible, heat resistant, heat stable, microwave transparent film, and a layer of substantially continuous microwave susceptor material located on an interior surface of a film of the laminate.

Abstract: The present invention provides a composite material for generation of heat by absorption of microwave energy comprising a porous dielectric substrate and a coating comprising a thermoplastic dielectric matrix and flakes of a micorwave susceptive material distributed within the matrix, said flakes having an aspect ratio of at least about 10, a generally planar, plate-like shape, with a thickness of about 0.1 to about 1.0 micrometers, a transverse dimension of about 1 to about 50 micrometers, and angular edges. The composite material exhibits decreased microwave transmission as a function of previously applied pressure.

Abstract: A package for uniform microwave cooking of a food item such as an egg roll, which requires surface browning or crispening, comprises a drapable, liquid permeable, microwave susceptive composite material draped around the food item, and a paper board holder having at least one cutout portion into which the wrapped food item nestles.

Abstract: A heat-shrinkable barrier film comprised of an oriented polyolefin film coated on one side with a vinylidene chloride copolymer are disclosed. The films have excellent gas and vapor barrier properties, can surprisingly be made using conventional dispersion coating techniques, and retain acceptable optical properties even on shrinking up to as high as 35% in either transverse or machine directions or both.
