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.

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 microwave heating construct may include a widened base. The construct may be erected by folding end panels of the construct towards one another and optionally securing the panels in the folded position. The construct may be formed from a blank. The construct and/or blank may include a removable portion at least partially defined by a line of disruption.

A container for heating a plurality of food items with microwave energy. The container can comprise a tray comprising a sidewall extending at least partially around an interior of the tray, an insert disposed at least partially in the interior of the tray, and a plurality of receptacles at least partially defined by the insert. Each receptacle of the plurality of receptacles can be for at least partially receiving at least one food item of the plurality of food items.

A microwave heating construct comprises a base, a wall extending upwardly around the base for defining a cavity for receiving a food item, and a microwave energy shielding element overlying a lower margin of the wall, the microwave energy shielding element having an upper edge including a substantially incurved portion.
