A microwave reheating container for food including a concave base and a cover. The base and cover both have a core formed of PET sheet material, formed into the appropriate base and cover shapes. The PET cores are crystallized to CPET on their interior. Each core is overmolded on its exterior with TPC capable of injection molding and having greater strength. The cover may include an elastomeric seal about its periphery. The cover may be secured to the base by one or more locking clips.

A packaging or wrapping for a food product, capable of resisting to high temperatures and of eliminating the overpressure generated by the water vapour inside the packaging due to temperature rise, without the same packaging having any aperture communicating its inside and the outside environment. The packaging is also adapted to restrain/reduce the emission of odor-generating substances that are generated during the heating or baking of the packaged food product, with respect to what occurs in the absence of a packaging, or with a packaging provided with apertures.

The present invention relates to paper or paperboard comprising cellulose fibers, said paper or paperboard comprising at least one coating layer formed by extrusion coating of a PP (polypropylene) resin, characterized in that the PP resin comprises at least 50% by weight of a branched PP copolymer having a density in the range of 890-910 kg/m.sup.3 (as determined according to ISO 1183), a melting temperature in the range of 155-170° C. (as determined according to ISO 11357-3), and a melt flow rate (230° C./2.16 kg) in the range of 10-15 g/10 min (as determined according to ISO 1133), and wherein the PP resin is applied to the paper or paperboard at a grammage of less than 30 g/m.sup.2.

Methods and apparatus for vacuum forming and subsequently applying topical coatings fiber-based food containers. The slurry includes an embedded moisture barrier and/or vapor barrier, and the topical coating comprises an oil barrier comprising acrylate, rice bran wax, pectin, and pea protein.

A microwaveable container for holding food includes a first container, a second container and a lid. The first container has a lower food holding space sized and shaped to hold a first food and a second container receiving space disposed above the lower food holding space. The first container has a shoulder extending outward from the lower food holding space. The second container nests with the first container and has an upper food holding space sized and shaped to hold a second food. The second container is positionable in the second container receiving space of the first container such that the second container separates the first and second foods held in the respective lower and upper food holding spaces. The second container engages and rests on the shoulder of the first container when nested. The lid attaches directly to the first container.

The present invention relates to a container for liquid containing food products, manufactured by press forming of a polymer coated fiber based substrate, said container comprising a bottom portion, a sidewall portion and a top flange portion, wherein said press forming has resulted in the formation a plurality of creases extending in a direction from the bottom portion to the top flange portion and further across the top flange portion. The container comprises an indentation pattern (130, 140, 150, 160, 170, 180, 190a, 190b, 200) formed at a creased inner surface of said sidewall portion and/or at a creased top surface of said top flange portion, said indentation pattern preventing migration of liquid from a liquid containing food product in the container along said creases. The invention relates also to a method for manufacturing such container.

The present invention relates to the technical field of pizza boxes, comprising a box body and a top cover. The box body and the top cover have triangular sector structures. The top end of the box body is open, and the edge of the open end extends outward to form a clamping flange; a lower end surface of the top cover is hermetically abutted against an upper end surface of the clamping flange; the side wall of the top cover is hinged with a plurality of claw buckles along a circumferential direction; the claw buckles have clamping plates and are clamped with the lower end surface of the clamping flange; and the bottom of the box body and the edge of the top cover are wrapped with heat insulation layers. The heat insulation pizza box of the present invention has good sealing and heat insulation effects.

An object is to provide a microwave container configured to precisely discharge vapor from a vapor-discharging part to avoid any vapor discharge from the remaining portions, and the microwave container includes: a container main body having an opening in its upper portion; a flange part formed to extend outwardly from the opening of the container main body; and a heat-seal part in a rib shape formed over the entire periphery of an upper surface of the flange part and heat-sealed to a film-shaped lid member for sealing the opening, wherein the heat-seal part includes a first heat-seal part for discharging vapor generated in the container main body by breaking the heat seal with the lid member when the vapor reaches a predetermined pressure, and a second heat-seal part wider than the first heat-seal part.

A container for holding a food product. The container can comprise a base layer and a liner at least partially attached to an inner surface of the base layer, a flange comprising a central panel of the base layer, an opening extending in the central panel, and a sidewall comprising at least a panel foldably connected to the central panel along the opening.

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.
