RFID tags are provided for incorporation into the packaging of a microwavable food item, with the RFID tag being configured to be safely microwaved. The RFID tag includes an antenna defining a gap and configured to operate at a first frequency. An RFID chip is electrically coupled to the antenna across the gap. A shielding structure is electrically coupled to the antenna across the gap and overlays the RFID chip. The shielding structure includes a shield conductor and a shield dielectric at least partially positioned between the shield conductor and the RFID chip. The shielding structure is configured to limit the voltage across the gap when the antenna is exposed to a second frequency that is greater than first frequency. In additional embodiments, RFID tags are provided for incorporation into the packaging of a microwavable food item, with the RFID tag being configured to be safely microwaved. The RFID tag includes an RFID chip and an antenna electrically coupled to the RFID chip. The antenna may have a sheet resistance in the range of approximately 100 ohms to approximately 230 ohms, optionally with an optical density in the range of approximately 0.18 to approximately 0.29. Alternatively, or additionally, the antenna may be configured to fracture into multiple pieces upon being subjected to heating in a microwave oven. Alternatively, or additionally, the RFID tag may be incorporated in an RFID label that is secured to the package by a joinder material with a greater resistance than that of the antenna, such as a sheet resistance in the range of approximately 100 ohms to approximately 230 ohms.

A method of manufacturing the microwave oven cooking utensil includes: an upper heating body and a lower heating body each of which absorbs a microwave and generates a heat; and a heating space for heating a food material located between the upper heating body and the lower heating body, the heating being performed from above and below at the same time. Here, the upper heating body and the lower heating body are each formed by including a heat generating part containing ferrite and a molded foam body.

A construct includes at least one panel for supporting a food product, the at least one panel formed from a laminate structure having a base layer, a conductive layer, and a surface film. The construct further includes at least one spacing feature extending downwardly from the at least one panel for supporting the at least one panel a distance above an induction source for attenuating heat transferred to the food product in response to an oscillating magnetic field interacting with the conductive layer of the laminate structure.

A moulded pulp container for food includes a main body formed from a moulded pulp material and a pulp tab portion. The main body includes a base, upstanding walls extending from the base, and an outer edge defining a container having an inner surface and an outer surface. The pulp tab portion is connected to and arranged outboard of the outer edge. The pulp tab portion has an upper surface and a lower surface. A barrier membrane laminated to the inner surface of the container and the upper surface of the pulp tab portion is removable when the pulp tab portion is detached from the main body, such that the barrier membrane remains bonded to both the main body and the pulp tab portion, which enables the barrier membrane to be peeled from the main body by pulling the pulp tab portion.

A container that includes a microwave interactive web at least partially overlying and joined to a three-dimensional support, wherein the three-dimensional support may be formed prior to having the microwave interactive web mounted thereto. The three-dimensional support may be a preformed container that is sufficiently rigid and dimensionally stable for use in containing food.

A packaging device including a breathable or non-breathable, microwavable composite film structure in the form of a bag, a tray or other type of container is disclosed. The device may include atmospheric control attributes in the form of microperforations, and steam venting mechanisms in the form of precision cuts or channels. The microperforations may form atmospheric conditions within the device for the storage of perishable and/or respiring food products, and the steam venting mechanisms may regulate the pressure and/or heat within the device during microwave cooking of the food products within.

An examination of microwave oven-resistant sheets for heat-insulating foamed paper containers revealed that blisters occur in the containers in the course of microwave oven treatment. That is to say, the present invention addresses the problem of providing a sheet for heat-insulating foamed paper container such that no blisters occur during microwave oven treatment. The present inventors have found that the problem to be solved by the present invention can be solved by a method for producing a sheet for a heat-insulating foamed paper container, wherein an air gap of 150 mm or larger, a drawing speed of 65 m/minute or lower, and a polyethylene resin density of 923 to 930 kg/m.sup.3.

A process for the production of instant alternative protein products, including plant based meat and more particularly to plant based products having the texture, appearance, and taste of meat or dairy. The instant meat or food analog material may be based on a Native Edestin Protein Isolate (NEPI). NEPI may be combined with water to form a protein hydrosol, followed by addition of oil, and heating in a microwave oven to set, thereby forming a hydrogel, or meat analog. The protein hydrosol may be mixed in a microwavable cup being comprised, preferably, of a porous material such as paper or plastic, and having dimensions conducive to forming a meat analog from the protein-fat hydrosol when heated in a microwave. Materials required for production of a meat analog at home from the NEPI may be provided as a convenient kit for production of an instant meat analog.

A package is configured for heating a food in a solid state microwave oven, and a method heats a food in a solid state microwave oven. Particularly, the package comprises includes a tray and a susceptor, and a thermal insulation is positioned between the susceptor and a food to be placed in the tray.
