A method of manufacturing a foil for enclosing or wrapping a product configured to be heated in an oven includes: providing an aluminium layer, applying a first ink material at a surface of the aluminium layer to form a first ink layer, and applying a second ink material at a surface of the first ink layer to form a second ink layer. The first ink layer is positioned between the aluminium layer and the second ink layer, and is configured to absorb radiant energy. The second ink layer is configured to allow radiant energy to pass through to reach the first ink layer. A binder system of the first ink material or the second ink material is based at least in part on polyvinyl butyral (PVB).

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 food container using a heating element, which container enhances convenience since a user can simply inject water toward the heating element by opening an inflow passage of an outer container without removing an inner container, and can keep the heating element stable in a simplified structure since a space containing the heating element inside the outer container and a space containing water are formed to be divided by a protrusion jaw but to communicate with each other.

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 packaged food product with a seasoning disk is provided. The food product includes potatoes. The seasoning disk includes seasoning and fat that is in solid form at the food product's anticipated normal storage temperature. The fat includes milkfat.

A package includes: a film including a crystalline stretched oriented film; and a breaking portion provided in the film and including one or more non-oriented portions formed by heating a part of the crystalline stretched oriented film at a temperature equal to or higher than a melting point of the crystalline stretched oriented film and facing each other with an oriented portion of the crystalline stretched oriented film interposed therebetween.

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.

Embodiments include a container with a leak resistant seal. The leak resistant seal provides access to the inside of the container when the leak resistant seal is open. The leak resistant seal includes first and second seal portions that are configured to be coupled together to close the container. A gap is arranged between ends of the first seal portion and the second seal portion, which provides an abutment that each of the ends of the first and second seal portions contact when the first seal portion is coupled to the second seal portion.

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.
