Abstract: A microwave packaging material for forming a construct for holding a food item. The microwave packaging material can include a film at least partially secured to a substrate by a pattern of adhesive. A plurality of closed cells can extend between the film and the substrate, each closed cell of the plurality of closed cells can be at least partially defined by the pattern of adhesive, and each of the closed cells can be configured to expand during heating to form respective expanded cells. The microwave packaging material further can include a bonded region extending along at least a portion of the microwave packaging material. The film can be secured to the substrate along the bonded region, and the bonded region can be for forming at least one recess among the expanded cells and can be for extending along the food item when the microwave packaging material is heated.

Abstract: A container for heating a food product with microwave energy having a wavelength. The container can include a generally circular centerline having an axis, and a receptacle including a sidewall extending at least partially around a cavity. At least a portion of the cavity can extend along at least a portion of the centerline. The sidewall can include an inner edge and an outer edge each being spaced apart from the axis of the centerline for at least partially retaining the food product in the cavity in proximity to the centerline.

Abstract: A microwave heating construct that includes a bottom and upstanding side walls formed from a first pair of opposing side walls and a second pair of opposing side walls. The first pair of opposing side walls being substantially parallel and the second pair of opposing side walls being substantially parallel. The first pair of opposing side walls being connected to the second pair of opposing side walls along corners to form a continuous upper surface above the bottom. The construct includes at least one raised surface disposed above the bottom with the at least one raised surface being defined by an upper surface that slopes downwardly to the bottom. The construct can be packaged with a pad and a product to be heated under a film.
