A container formed from a blank, a forming, tool and a method of forming a container are disclosed. The container includes features that are formed by a plurality of score lines in a marginal portion of the blank. The container has a bottom wall, a side wall, and a flange extending from the side wall. The flange has a thickness that is greater than a thickness of the blank.

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 frame is injection molded onto a group of panels to form a container. The panels extend at least partially around, and at least partially define, a cavity of the container.

A method for forming a container having an injection-molded feature. The method includes obtaining a blank, forming the blank into a three-dimensional article having at least one sidewall, and forming the injection-molded feature extending around the perimeter of the article. The injection-molded feature comprises an anchor portion and a flange portion. The anchor portion is in contact with an interior surface of the at least one sidewall and the flange portion extends from the anchor portion outwardly from the at least one sidewall.

A method for forming a laminate can comprise moving an initial laminate and a sacrificial web at least partially coated with an adhesive in a downstream direction. The initial laminate can comprise a base web and an interactive web comprising a retained section and a scrap section. The method also can comprise forming a compound laminate by nipping the sacrificial web and at least the scrap section of the interactive web between a raised feature of a nip roller and an opposing support surface so that the adhesive at least partially bonds the sacrificial web to the scrap section. In addition, the method can comprise separating the compound laminate into a resultant laminate, comprising the base web and at least the retained section of the interactive web, and a sacrificial laminate, comprising the sacrificial web and at least the scrap section of the interactive web.

A package for combined steam and microwave heating of food, wherein the package may include microwave energy interactive materials (MEIMs) configured for providing rapid, simultaneous microwave and steam cooking in a domestic microwave oven. The MEIMs may be configured for controlling the heating pattern within the package and to control volumetric heating of food in the package. The MEIMs may include one or more of a susceptor, shield, and/or resonating patch antenna. The package may be paper-based, or it may be manufactured of any other suitable material. One or more of the different sections of the package may comprise separate chambers respectively for the steam source and the food to be steamed, so that the steam source and the food to be steamed are separated from one another during manufacturing, storage, and cooking.

Portions of microwave energy interactive material may be cut and removed during intermediate steps in a lamination processes, so that remaining microwave energy interactive material in a resultant laminate is arranged in a pattern. Regarding the removal of the portions of the microwave energy interactive material, a compound laminate may be delaminated into parts, and one of the parts may be a sacrificial laminate that includes the removed portions of the microwave energy interactive material.

A container for holding at least a first food item and a second food item. The container can comprise a sidewall with a microwave energy interactive layer. A shielded interior portion of an interior of the container can be defined by at least the microwave energy interactive layer and can be for at least partially receiving the first food item. An at least partially unshielded interior portion of the interior of the container can be at least partially defined by the sidewall and can be for at least partially receiving the second food item. A plurality of apertures can extend through at least the microwave energy interactive layer, and each aperture can have a characteristic dimension that is selected based on a cutoff frequency of a microwave oven to be sufficiently small so that substantially all microwave energy incident on the container is substantially prevented from passing through the apertures.
