A food packaging includes a food product and a microwave susceptor for emitting infrared energy. The microwave susceptor has a susceptor plate including a non-conductive material and an electrically conductive component imparting electrical conductivity. The susceptor element has a resistance of 10 to 1000 Ohm/square, preferably 30 to 300 Ohm/square, and the susceptor plate is capable of withstanding a temperature above 400 C.

A self-supporting flexible film container is disclosed that includes a container base and a flexible film attached to the container base that forms a container wall and defines a packing region within the container. The container wall has at least one support column, such as a tubular support column, integrally formed therein. A method of conforming the container includes providing a web of flexible film, forming tubular support columns in the web of flexible film and forming a container from the web of flexible film containing the support columns. The support columns can be formed by ploughing and forming the web of flexible film.

A hermetically sealed package, for example a freezable microwavable package containing a food product, has a sealing film that includes a vent system that is scored by a laser into the package.

An ovenable package comprises an ovenable receptacle configured to hold a food product. The receptacle has an open face surrounded by a rim. An ovenable laminated film lid is attached to the rim of the receptacle by a welded seal between a lower face of the laminated film lid and the rim of the receptacle. The laminated film lid comprises a first layer, a second layer above the first layer and a resealable adhesive between the first and second layers. An unopened package is openable by separating the second layer from the first layer in a peripheral region. The opened package can be reclosed to a ventable state by reattaching the second layer to the peripheral region of the first layer by the resealable adhesive. The ventable state permits venting of gas from an interior of the receptacle between the second layer and the peripheral region of the first layer.

Packaging material includes microwave interactive material and is automatically reconfigurable for selectively controlling transmission of microwave energy through the packaging material. The packaging material is configured to vary, as a function of time, a ratio of microwave energy transmitted through the packaging material. The packaging material is configured so that the microwave energy is automatically selectively transmitted in different ratios.

The purpose of the present invention is to provide: a packaging container that can be industrially mass-produced, that can be used as Modified Atmosphere Packaging (MAP) while ensuring sealing performance, and that allows contents to be displayed in a three-dimensional manner; a packaged product contained in the packaging container; and a manufacturing method and manufacturing apparatus for the packaging container. This packaging container has: a container main body having a bottom face part and sidewall parts, and having a flange at the upper end part periphery of the sidewall parts; and a lid material heat-sealed to the flange. The lid material is made of a film or sheet. A pair of opposing sidewall parts has the same shape, and upper end parts of the pair of side wall parts are at least positioned higher than the upper end parts of another pair of opposing sidewall parts.

A microwave pot includes an upper lid made of metal and a pot body. A microwave absorption layer is provided on the outer surface of the bottom wall of the pot body and used for absorbing electromagnetic waves emitted by a microwave oven and converting into heat. An opening of the upper lid and/or the pot body is provided with a first flange; a plurality of first through holes are formed in the first flange; silica gel members are provided on the upper and lower surfaces wrapping the first flange; the silica gel members are integrally formed with the first flange and fill the first through holes, thus the silica gel members cannot be separated from the first flange after molding. The first flange and the silica gel members are integrally formed, which improves the combination firmness, and improves user experience of a user.

The present invention relates to a susceptor combination comprising: metallic particles; particles of at least two or more semiconductor materials; and one or more alkaline or alkaline earth metal salts; to a susceptor ink composition containing it. It also relates to a laminate comprising a dielectric substrate and the susceptor ink composition printed on the substrate, as well as a microwaveable package comprising the laminate.

A microwavable food packaging can be configured to absorb fluid. The packaging can include a first sheet and a flexible second sheet. The first sheet can include a first polymeric layer. The first sheet can define an upper portion of a food pocket. The flexible second sheet can include an absorbent layer. The absorbent layer can include a paper-based side and a polymer-based side. The paper-based side can include paper fibers, define a bottom of the food pocket and be configured to absorb fluid released from food disposed within the food pocket. The first polymeric layer can be bonded to the polymer-based side through the paper-based side to form a non-hermetic seal, the non-hermetic seal enabling passage of moisture therethrough.
